Terms, Icons, and Labels

Many classes have shortcut names used when creating (instantiating) a class with a configuration object. The shortcut name is referred to as an alias (or xtype if the class extends Ext.Component). The alias/xtype is listed next to the class name of applicable classes for quick reference.

Access Levels

Framework classes or their members may be specified as private or protected. Else, the class / member is public. Public, protected, and private are access descriptors used to convey how and when the class or class member should be used.

Member Types

Member Syntax

Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).

lookupComponent ( item ) : Ext.Component
protected

Called when a raw config object is added to this container either during initialization of the items config, or when new items are added), or {@link #insert inserted.

This method converts the passed object into an instanced child component.

This may be overridden in subclasses when special processing needs to be applied to child creation.

Parameters

item :  Object

The config object being added.

Returns
Ext.Component

The component to be added.

Let's look at each part of the member row:

Member Flags

The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.

Class Icons

- Indicates a framework class

- A singleton framework class. *See the singleton flag for more information

- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)

- Indicates that the class, member, or guide is new in the currently viewed version

Member Icons

- Indicates a class member of type config

- Indicates a class member of type property

- Indicates a class member of type method

- Indicates a class member of type event

- Indicates a class member of type theme variable

- Indicates a class member of type theme mixin

- Indicates that the class, member, or guide is new in the currently viewed version

Class Member Quick-Nav Menu

Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.

Getter and Setter Methods

Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.

History Bar

Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.

Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.

If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.

Search and Filters

Both API docs and guides can be searched for using the search field at the top of the page.

On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.

The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.

Clicking on an empty search field will show your last 10 searches for quick navigation.

API Doc Class Metadata

Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:

Expanding and Collapsing Examples and Class Members

Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.

Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.

Desktop -vs- Mobile View

Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:

Viewing the Class Source

The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.

Ext.ux.statusbar.StatusBar xtype: statusbar

Summary

Basic status bar component that can be used as the bottom toolbar of any Ext.Panel. In addition to supporting the standard Ext.toolbar.Toolbar interface for adding buttons, menus and other items, the StatusBar provides a greedy status element that can be aligned to either side and has convenient methods for setting the status text and icon. You can also indicate that something is processing using the showBusy method.

Ext.create('Ext.Panel', {
    title: 'StatusBar',
    // etc.
    bbar: Ext.create('Ext.ux.StatusBar', {
        id: 'my-status',

        // defaults to use when the status is cleared:
        defaultText: 'Default status text',
        defaultIconCls: 'default-icon',

        // values to set initially:
        text: 'Ready',
        iconCls: 'ready-icon',

        // any standard Toolbar items:
        items: [{
            text: 'A Button'
        }, '-', 'Plain Text']
    })
});

// Update the status bar later in code:
var sb = Ext.getCmp('my-status');
sb.setStatus({
    text: 'OK',
    iconCls: 'ok-icon',
    clear: true // auto-clear after a set interval
});

// Set the status bar to show that something is processing:
sb.showBusy();

// processing....

sb.clearStatus(); // once completeed

configs

Optional Configs

actions : Object
bindable bind

An object containing properties which define named Ext.Action for this container and any descendant components.

An Action encapsulates a shareable, reusable set of properties which define a "clickable" UI component such as a Ext.button.Button or Ext.menu.Item, or panel header tool, or an Ext.grid.column.Action

An Action, or more conveniently, the name of an action prefixed with '@' may be used as a config object for creating child components which use a handler config property to reference a Controller method to invoke when the component is clicked.

The property name is the action name, which may then be used as a child item configuration in an items configuration in any descendant component such as a toolbar or a menu, or in a tools configuration of a Panel.

The property value is a configuration object for any clickable component.

See the Ext.Action class for an example of reusable Actions.

Defaults to:

null

Available since: 6.2.0

getActions : Object

Returns the value of actions

Returns

Object

setActions (actions)

Sets the value of actions

Parameters

actions :  Object

activeChildTabIndex : Number

DOM tabIndex attribute to set on the active Focusable child of this container when using the "Roaming tabindex" technique.

Defaults to:

0

activeCounter : Number
bindable bind private pri

An incrementing numeric counter indicating activation index for use by the zIndexManager to sort its stack.

Defaults to:

0

getActiveCounter : Number

Returns the value of activeCounter

Returns

Number

setActiveCounter (activeCounter)

Sets the value of activeCounter

Parameters

activeCounter :  Number

activeItem : String / Number
bindable bind

A string component id or the numeric index of the component that should be initially activated within the container's layout on render. For example, activeItem: 'item-1' or activeItem: 0 (index 0 = the first item in the container's collection). activeItem only applies to layout styles that can display items one at a time (like Ext.layout.container.Card and Ext.layout.container.Fit).

Available since: 2.3.0

setActiveItem ( item ) : Ext.Component

Sets a component as the active layout item. This only applies when using a Ext.layout.container.Card layout.

var card1 = Ext.create('Ext.panel.Panel', {itemId: 'card-1'});
var card2 = Ext.create('Ext.panel.Panel', {itemId: 'card-2'});
var panel = Ext.create('Ext.panel.Panel', {
    layout: 'card',
    items: [card1, card2]
});
// These are all equivalent
panel.getLayout().setActiveItem(card2);
panel.getLayout().setActiveItem('card-2');
panel.getLayout().setActiveItem(1);

Parameters

item :  Ext.Component/Number/String

The component, component id, itemId, or index of component.

Returns

:Ext.Component

the activated component or false when nothing activated. False is returned also when trying to activate an already active item.

alignOnScroll : Boolean

By default, when the alignTo method is called, a floating component will scroll to keep aligned with the anchoring element if the anchoring element is part of the scroll.

If this is not necessary, and the alignTo is a one-off operation then set this config to false.

Defaults to:

true

alignTarget : String

A Component or Element by which to position this component according to the defaultAlign. Defaults to the owning Container.

Only applicable if this component is cfg-floating

Used upon first show.

Defaults to:

null

allowFocusingDisabledChildren : Boolean

Set this to true to enable focusing disabled child items via keyboard.

Defaults to:

false

alwaysOnTop : Boolean / Number
bindable bind

A flag indicating that this component should be on the top of the z-index stack for use by the zIndexManager to sort its stack.

This may be a positive number to prioritize the ordering of multiple visible always on top components.

This may be set to a negative number to prioritize a component to the bottom of the z-index stack.

Defaults to:

false

getAlwaysOnTop : Boolean / Number

Returns the value of alwaysOnTop

Returns

Boolean / Number

setAlwaysOnTop (alwaysOnTop)

Sets the value of alwaysOnTop

Parameters

alwaysOnTop :  Boolean / Number

anchor : String

This configuration option is to be applied to child items of a container managed by an Ext.layout.container.Anchor.

This value is what tells the layout how an item should be anchored to the container. items added to an AnchorLayout accept an anchoring-specific config property of anchor which is a string containing two values: the horizontal anchor value and the vertical anchor value (for example, '100% 50%'). The following types of anchor values are supported:

  • Percentage : Any value between 1 and 100, expressed as a percentage.

    The first anchor is the percentage width that the item should take up within the container, and the second is the percentage height. For example:

    // two values specified
    anchor: '100% 50%' // render item complete width of the container and
                       // 1/2 height of the container
    // one value specified
    anchor: '100%'     // the width value; the height will default to auto
    
  • Offsets : Any positive or negative integer value.

    This is a raw adjustment where the first anchor is the offset from the right edge of the container, and the second is the offset from the bottom edge. For example:

    // two values specified
    anchor: '-50 -100' // render item the complete width of the container
                       // minus 50 pixels and
                       // the complete height minus 100 pixels.
    // one value specified
    anchor: '-50'      // anchor value is assumed to be the right offset value
                       // bottom offset will default to 0
    
  • Sides : Valid values are right (or r) and bottom (or b).

    Either the container must have a fixed size or an anchorSize config value defined at render time in order for these to have any effect.

  • Mixed :

    Anchor values can also be mixed as needed. For example, to render the width offset from the container right edge by 50 pixels and 75% of the container's height use:

    anchor:   '-50 75%'
    

anchorSize : Number / Object

Defines the anchoring size of container. Either a number to define the width of the container or an object with width and height fields.

animateShadow : Boolean

true to animate the shadow along with the component while the component is animating. By default the shadow is hidden while the component is animating

Defaults to:

false

ariaAttributes : Object
bindable bind

An object containing ARIA attributes to be set on this Component's ARIA element. Use this to set the attributes that cannot be determined by the Component's state, such as aria-live, aria-flowto, etc.

Note that this config is only meaningful at the Component rendering time, and setting it after that will do nothing.

Defaults to:

null

getAriaAttributes : Object

Returns the value of ariaAttributes

Returns

Object

setAriaAttributes (ariaAttributes)

Sets the value of ariaAttributes

Parameters

ariaAttributes :  Object

ariaDescribedBy : String

DOM selector for a child element that is to be used as description for this Component, set in aria-describedby attribute. The selector works the same way as ariaLabelledBy.

ariaLabel : String

ARIA label for this Component. It is best to use ariaLabelledBy option instead, because screen readers prefer aria-labelledby attribute to aria-label. ariaLabel and ariaLabelledBy config options are mutually exclusive.

ariaLabelledBy : String

DOM selector for a child element that is to be used as label for this Component, set in aria-labelledby attribute. If the selector is by id, the label element can be any existing element, not necessarily a child of the main Component element.

ariaLabelledBy and ariaLabel config options are mutually exclusive, and ariaLabelledBy has the higher precedence.

autoClear : Number

The number of milliseconds to wait after setting the status via setStatus before automatically clearing the status text and icon. Note that this only applies when passing the clear argument to setStatus since that is the only way to defer clearing the status. This can be overridden by specifying a different wait value in setStatus. Calls to clearStatus always clear the status bar immediately and ignore this value.

Defaults to:

5000

autoDestroy : Boolean

If true the container will automatically destroy any contained component that is removed from it, else destruction must be handled manually.

Defaults to:

true

Available since: 2.3.0

autoEl : String / Object

A tag name or Ext.dom.Helper spec used to create the Element which will encapsulate this Component.

You do not normally need to specify this. For the base classes Ext.Component and Ext.container.Container, this defaults to 'div'. The more complex Sencha classes use a more complex DOM structure specified by their own cfg-renderTpls.

This is intended to allow the developer to create application-specific utility Components encapsulated by different DOM elements. Example usage:

{
    xtype: 'component',
    autoEl: {
        tag: 'img',
        src: 'http://www.example.com/example.jpg'
    }
}, {
    xtype: 'component',
    autoEl: {
        tag: 'blockquote',
        html: 'autoEl is cool!'
    }
}, {
    xtype: 'container',
    autoEl: 'ul',
    cls: 'ux-unordered-list',
    items: {
        xtype: 'component',
        autoEl: 'li',
        html: 'First list item'
    }
}

Available since: 2.3.0

autoRender : Boolean / String / HTMLElement / Ext.dom.Element

This config is intended mainly for non-cfg-floating Components which may or may not be shown. Instead of using renderTo in the configuration, and rendering upon construction, this allows a Component to render itself upon first show. If cfg-floating is true, the value of this config is omitted as if it is true.

Specify as true to have this Component render to the document body upon first show.

Specify as an element, or the ID of an element to have this Component render to a specific element upon first show.

Defaults to:

false

autoScroll : Boolean
deprecated dep bindable bind

true to use overflow:'auto' on the components layout element and show scroll bars automatically when necessary, false to clip any overflowing content.

This should not be combined with overflowX or overflowY.

Defaults to:

false

Deprecated since version 5.1.0
Use scrollable instead

setAutoScroll ( scroll ) : Ext.Component
chainable ch deprecated dep

Sets the overflow on the content element of the component.

Parameters

scroll :  Boolean

True to allow the Component to auto scroll.

Returns

:Ext.Component

this

Deprecated since version 5.0.0
Use setScrollable instead

autoShow : Boolean

true to automatically show the component upon creation. This config option may only be used for cfg-floating components or components that use autoRender.

Defaults to:

false

Available since: 2.3.0

baseCls : String

The base CSS class to apply to this component's element. This will also be prepended to elements within this component like Panel's body will get a class x-panel-body. This means that if you create a subclass of Panel, and you want it to get all the Panels styling for the element and the body, you leave the baseCls x-panel and use componentCls to add specific styling for this component.

Defaults to:

Ext.baseCSSPrefix + 'container'

bind : Object / String
bindable bind

Setting this config option adds or removes data bindings for other configs. For example, to bind the title config:

 var panel = Ext.create({
     xtype: 'panel',
     bind: {
         title: 'Hello {user.name}'
     }
 });

To dynamically add bindings:

 panel.setBind({
     title: 'Greetings {user.name}!'
 });

To remove bindings:

 panel.setBind({
     title: null
 });

The bind expressions are presented to Ext.app.ViewModel#bind. The ViewModel instance is determined by lookupViewModel.

Note: If bind is passed as a string, it will use the Ext.Component#property-defaultBindProperty for the binding.

Defaults to:

null

getBind : Object / String

Returns the value of bind

Returns

Object / String

setBind (bind)

Sets the value of bind

Parameters

bind :  Object / String

border : Number / String / Boolean
bindable bind

Specifies the border size for this component. The border can be a single numeric value to apply to all sides or it can be a CSS style specification for each style, for example: '10 5 3 10' (top, right, bottom, left).

For components that have no border by default, setting this won't make the border appear by itself. You also need to specify border color and style:

border: 5,
style: {
    borderColor: 'red',
    borderStyle: 'solid'
}

To turn off the border, use border: false.

setBorder ( border )

Parameters

border :  String/Number

The border, see border. If a falsey value is passed

bubbleEvents : String[]

An array of events that, when fired, should be bubbled to any parent container. See Ext.util.Observable#enableBubble.

Available since: 3.4.0

busyIconCls : String

The default iconCls applied when calling showBusy. It can be overridden at any time by passing the iconCls argument into showBusy.

Defaults to:

'x-status-busy'

busyText : String

The default text applied when calling showBusy. It can be overridden at any time by passing the text argument into showBusy.

Defaults to:

'Loading...'

childEls : Object / String[] / Object[]
bindable bind

The canonical form of childEls is an object keyed by child's property name with values that are objects with the following properties.

  • itemId - The id to combine with the Component's id that is the id of the child element.
  • id - The id of the child element.
  • leaf - Set to true to ignore content when scanning for childEls. This should be set on things like the generated content for an Ext.view.View.
  • select: A selector that will be passed to Ext.dom.Element#method-select.
  • selectNode: A selector that will be passed to Ext.dom.Element#method-selectNode.

For example:

 childEls: {
     button: true,
     buttonText: 'text',
     buttonImage: {
         itemId: 'image'
     }
 }

The above is translated into the following complete form:

 childEls: {
     button: {
         name: 'button',
         itemId: 'button'
     },
     buttonText: {
         name: 'buttonText',
         itemId: 'text'
     },
     buttonImage: {
         name: 'buttonImage',
         itemId: 'image'
     }
 }

The above can be provided as an array like so:

 childEls: [
     'button',
     { name: 'buttonText', itemId: 'text' },
     { name: 'buttonImage', itemId: 'image' }
 }

For example, a Component which renders a title and body text:

Note: childEls in the renderTpl must be referenced in a data-ref attribute. Notice in the above example that the "title" childEl is set in the renderTpl using data-ref="title".

When using select, the property will be an instance of Ext.CompositeElement. In all other cases, the property will be an Ext.dom.Element or null if not found.

Care should be taken when using select or selectNode to find child elements. The following issues should be considered:

  • Performance: using selectors can be 10x slower than id lookup.
  • Over-selecting: selectors are applied after the DOM elements for all children have been rendered, so selectors can match elements from child components (including nested versions of the same component) accidentally.

This above issues are most important when using select since it returns multiple elements.

Defaults to:

{}

getChildEls : Object / String[] / Object[]

Returns the value of childEls

Returns

Object / String[] / Object[]

setChildEls (childEls)

Sets the value of childEls

Parameters

childEls :  Object / String[] / Object[]

cls : String

The base class applied to the containing element for this component on render.

Defaults to:

'x-statusbar'

columnWidth : Number

Defines the column width inside Ext.layout.container.Column.

The columnWidth property is always evaluated as a percentage and must be a decimal value greater than 0 and less than 1 (e.g., .25). See the description at the top of Ext.layout.container.Column for additional usage details when combining width and columnWidth configs within the layout.

componentCls : String

CSS Class to be added to a components root level element to give distinction to it via styling.

componentLayout : String / Object
bindable bind

The sizing and positioning of a Component's internal Elements is the responsibility of the Component's layout manager which sizes a Component's internal structure in response to the Component being sized.

Generally, developers will not use this configuration as all provided Components which need their internal elements sizing (Such as Ext.form.field.Base) come with their own componentLayout managers.

The Ext.layout.container.Auto will be used on instances of the base Ext.Component class which simply sizes the Component's encapsulating element to the height and width specified in the setSize method.

Defaults to:

'autocomponent'

setComponentLayout ( layout )
private pri

Parameters

layout :  Object

constrain : Boolean

True to constrain this Components within its containing element, false to allow it to fall outside of its containing element. By default this Component will be rendered to document.body. To render and constrain this Component within another element specify renderTo.

Defaults to:

false

constraintInsets : Object / String

An object or a string (in TRBL order) specifying insets from the configured constrain region within which this component must be constrained when positioning or sizing. Example:

constraintInsets: '10 10 10 10' // Constrain with 10px insets from parent

constrainTo : Ext.util.Region / Ext.dom.Element

A Ext.util.Region (or an element from which a Region measurement will be read) which is used to constrain the component. Only applies when the component is floating.

contentEl : String

Specify an existing HTML element, or the id of an existing HTML element to use as the content for this component.

This config option is used to take an existing HTML element and place it in the layout element of a new component (it simply moves the specified DOM element after the Component is rendered to use as the content.

Notes:

The specified HTML element is appended to the layout element of the component after any configured HTML has been inserted, and so the document will not contain this element at the time the event-render event is fired.

The specified HTML element used will not participate in any layout scheme that the Component may use. It is just HTML. Layouts operate on child items.

Add either the x-hidden or the x-hidden-display CSS class to prevent a brief flicker of the content before it is rendered to the panel.

Available since: 3.4.0

controller : String / Object / Ext.app.ViewController
bindable bind

A string alias, a configuration object or an instance of a ViewController for this container. Sample usage:

Ext.define('MyApp.UserController', {
    alias: 'controller.user'
});

Ext.define('UserContainer', {
    extend: 'Ext.container.container',
    controller: 'user'
});
// Or
Ext.define('UserContainer', {
    extend: 'Ext.container.container',
    controller: {
        type: 'user',
        someConfig: true
    }
});

// Can also instance at runtime
var ctrl = new MyApp.UserController();
var view = new UserContainer({
    controller: ctrl
});

Defaults to:

null

getController Ext.app.ViewController

Returns the Ext.app.ViewController instance associated with this component via the controller config or setController method.

Returns

:Ext.app.ViewController

Returns this component's ViewController or null if one was not configured

setController (controller)

Sets the value of controller

Parameters

controller :  String / Object / Ext.app.ViewController

data : Object
bindable bind

The initial set of data to apply to the tpl to update the content area of the Component.

Defaults to:

null

Available since: 3.4.0

getData : Object

Returns the value of data

Returns

Object

setData (data)

Sets the value of data

Parameters

data :  Object

defaultAlign : String

The default Ext.dom.Element#getAlignToXY anchor position value for this component relative to its alignTarget (which defaults to its owning Container).

Only applicable if this component is cfg-floating

Used upon first show.

Defaults to:

'c-c'

defaultButtonUI : String

A default ui to use for Ext.button.Button items. This is a quick and simple way to change the look of all child Ext.button.Button.

If there is no value for defaultButtonUI, the button's ui value will get -toolbar appended so the Ext.button.Button has a different look when it's a child of a Ext.toolbar.Toolbar. To prevent this and have the same look as buttons outside of a toolbar, you can provide a string value to the defaultButtonUI:

Ext.create('Ext.panel.Panel', {
    renderTo    : document.body,
    width       : 300,
    title       : 'Panel',
    html        : 'Some Body',
    dockedItems : [
        {
            xtype           : 'toolbar',
            dock            : 'top',
            defaultButtonUI : 'default',
            items           : [
                {
                    text : 'Save'
                },
                {
                    text : 'Remove'
                }
            ]
        }
    ]
});

Defaults to:

'default-toolbar'

defaultFieldUI : String

Default UI for form field items.

Defaults to:

'default'

defaultFocus : String

Specifies a child Component to receive focus when this Container's method-focus method is called. Should be a valid Ext.ComponentQuery selector.

getDefaultFocus

Finds the configured default focus item. See defaultFocus.

defaultFooterButtonUI : String

Default UI for Buttons if the toolbar has a UI of 'footer'

Defaults to:

'default'

defaultFooterFieldUI : String

Default UI for Form Fields if the toolbar has a UI of 'footer'

Defaults to:

'default'

defaultIconCls : String

The default iconCls value (see the iconCls docs for additional details about customizing the icon). This will be used anytime the status bar is cleared with the useDefaults:true option.

Defaults to:

''

defaultListenerScope : Boolean
bindable bind

If true, this component will be the default scope (this pointer) for events specified with string names so that the scope can be dynamically resolved. The component will automatically become the defaultListenerScope if a controller is specified.

See the introductory docs for Ext.container.Container for some sample usages.

NOTE: This value can only be reliably set at construction time. Setting it after that time may not correctly rewire all of the potentially effected listeners.

Defaults to:

false

getDefaultListenerScope : Boolean

Returns the value of defaultListenerScope

Returns

Boolean

setDefaultListenerScope (defaultListenerScope)

Sets the value of defaultListenerScope

Parameters

defaultListenerScope :  Boolean

defaults : Object / Function

This option is a means of applying default settings to all added items whether added through the cfg-items config or via the method-add or insert methods.

Defaults are applied to both config objects and instantiated components conditionally so as not to override existing properties in the item (see Ext#applyIf).

If the defaults option is specified as a function, then the function will be called using this Container as the scope (this reference) and passing the added item as the first parameter. Any resulting object from that call is then applied to the item as default properties.

For example, to automatically apply padding to the body of each of a set of contained Ext.panel.Panel items, you could pass: defaults: {bodyStyle:'padding:15px'}.

Usage:

defaults: { // defaults are applied to items, not the container
    scrollable: true
},
items: [
    // default will not be applied here, panel1 will be scrollable: false
    {
        xtype: 'panel',
        id: 'panel1',
        scrollable: false
    },
    // this component will have scrollable: true
    new Ext.panel.Panel({
        id: 'panel2'
    })
]

Available since: 2.3.0

defaultText : String

The default text value. This will be used anytime the status bar is cleared with the useDefaults:true option.

Defaults to:

''

defaultType : String

The default Ext.Component of child Components to create in this Container when a child item is specified as a raw configuration object, rather than as an instantiated Component.

Defaults to:

'panel'

Available since: 2.3.0

detachOnRemove : Boolean

True to move any component to the detachedBody when the component is removed from this container. This option is only applicable when the component is not destroyed while being removed, see autoDestroy and method-remove. If this option is set to false, the DOM of the component will remain in the current place until it is explicitly moved.

Defaults to:

true

disabled : Boolean
bindable bind

true to disable the component.

Defaults to:

false

Available since: 2.3.0

setDisabled ( disabled )
chainable ch

Enable or disable the component.

Parameters

disabled :  Boolean

true to disable.

disabledCls : String

CSS class to add when the Component is disabled.

Defaults to:

Ext.baseCSSPrefix + 'item-disabled'

dock : 'top' / 'bottom' / 'left' / 'right'
bindable bind

The side of the Ext.panel.Panel where this component is to be docked when specified in the panel's dockedItems config.

Possible values are:

  • top
  • bottom
  • left
  • right

setDock ( dock ) : Ext.Component
chainable ch

Sets the dock position of this component in its parent panel. Note that this only has effect if this item is part of the dockedItems collection of a parent that has a DockLayout (note that any Panel has a DockLayout by default)

Parameters

dock :  Object

The dock position.

Returns

:Ext.Component

this

draggable : Boolean / Object

Specify as true to make a cfg-floating Component draggable using the Component's encapsulating element as the drag handle.

This may also be specified as a config object for the Ext.util.ComponentDragger which is instantiated to perform dragging.

For example to create a Component which may only be dragged around using a certain internal element as the drag handle, use the delegate option:

new Ext.Component({
    constrain: true,
    floating: true,
    style: {
        backgroundColor: '#fff',
        border: '1px solid black'
    },
    html: '<h1 style="cursor:move">The title</h1><p>The content</p>',
    draggable: {
        delegate: 'h1'
    }
}).show();

Defaults to:

false

emptyText : String

The text string to use if no text has been set. If there are no other items in the toolbar using an empty string ('') for this value would end up in the toolbar height collapsing since the empty string will not maintain the toolbar height. Use '' if the toolbar should collapse in height vertically when no text is specified and there are no other items in the toolbar.

Defaults to:

'&#160;'

enableOverflow : Boolean

Configure true to make the toolbar provide a button which activates a dropdown Menu to show items which overflow the Toolbar's width. Setting this too true is the equivalent of setting overflowHandler:'menu'.

Defaults to:

false

fixed : Boolean

Configure as true to have this Component fixed at its X, Y coordinates in the browser viewport, immune to scrolling the document.

Defaults to:

false

flex : Number
bindable bind

Flex may be applied to child items of a box layout (Ext.layout.container.VBox or Ext.layout.container.HBox). Each child item with a flex property will fill space (horizontally in hbox, vertically in vbox) according to that item's relative flex value compared to the sum of all items with a flex value specified.

Any child items that have either a flex of 0 or undefined will not be 'flexed' (the initial size will not be changed).

setFlex ( flex )
private pri

Sets the flex property of this component. Only applicable when this component is an item of a box layout

Parameters

flex :  Number

floating : Boolean

Specify as true to float the Component outside of the document flow using CSS absolute positioning.

Components such as Ext.window.Windows and Ext.menu.Menus are floating by default.

Floating Components that are programmatically rendered will register themselves with the global Ext.WindowManager

Floating Components as child items of a Container

A floating Component may be used as a child item of a Container. This just allows the floating Component to seek a ZIndexManager by examining the ownerCt chain.

When configured as floating, Components acquire, at render time, a Ext.ZIndexManager which manages a stack of related floating Components. The ZIndexManager sorts its stack according to an incrementing access counter and the alwaysOnTop config when the Component's toFront method is called.

The ZIndexManager is found by traversing up the ownerCt chain to find an ancestor which itself is floating. This is so that descendant floating Components of floating Containers (Such as a ComboBox dropdown within a Window) can have its zIndex managed relative to any siblings, but always above that floating ancestor Container.

If no floating ancestor is found, a floating Component registers itself with the default Ext.WindowManager.

Floating components do not participate in the Container's layout. Because of this, they are not rendered until you explicitly method-show them.

After rendering, the ownerCt reference is deleted, and the floatParent property is set to the found floating ancestor Container. If no floating ancestor Container was found the floatParent property will not be set.

Defaults to:

false

focusableContainer : Boolean

Enable or disable navigation with arrow keys for this FocusableContainer. This option may be useful with nested FocusableContainers, when only the root container should handle keyboard events.

Defaults to:

false

focusCls : String

CSS class suffix that will be used to compose the CSS class name that will be added to Component's focusClsEl, and removed when Component blurs.

Note that this is not a full CSS class name; this suffix will be combined with component's UI class via addClsWithUI and removeClsWithUI methods.

Defaults to:

'focus'

focusOnToFront : Boolean

Specifies whether the floated component should be automatically focused when it is brought to the front.

Defaults to:

true

formBind : Boolean

When inside FormPanel, any component configured with formBind: true will be enabled/disabled depending on the validity state of the form. See Ext.form.Panel for more information and example.

Defaults to:

false

frame : Boolean

Specify as true to have the Component inject framing elements within the Component at render time to provide a graphical rounded frame around the Component content.

This is only necessary when running on outdated, or non standard-compliant browsers such as Microsoft's Internet Explorer prior to version 9 which do not support rounded corners natively.

The extra space taken up by this framing is available from the read only property frameSize.

height : Number / String
bindable bind

The height of this component. A numeric value will be interpreted as the number of pixels; a string value will be treated as a CSS value with units.

getHeight Number

Gets the current height of the component's underlying element.

Returns

:Number

setHeight ( height ) : Ext.Component

Sets the height of the component. This method fires the resize event.

Parameters

height :  Number

The new height to set. This may be one of:

  • A Number specifying the new height in pixels.
  • A String used to set the CSS height style.
  • undefined to leave the height unchanged.
  • null to clear the height.

Returns

:Ext.Component

this

hidden : Boolean
bindable bind

true to hide the component.

Defaults to:

false

Available since: 2.3.0

setHidden ( hidden ) : Ext.Component

Sets the hidden state of this component. This is basically the same as setVisible but the boolean parameter has the opposite meaning.

Parameters

hidden :  Boolean

Returns

:Ext.Component

hideMode : String

A String which specifies how this Component's encapsulating DOM element will be hidden. Values may be:

  • 'display' : The Component will be hidden using the display: none style.
  • 'visibility' : The Component will be hidden using the visibility: hidden style.
  • 'offsets' : The Component will be hidden by absolutely positioning it out of the visible area of the document. This is useful when a hidden Component must maintain measurable dimensions. Hiding using display results in a Component having zero dimensions.

Defaults to:

'display'

Available since: 1.1.0

html : String / Object
bindable bind

An HTML fragment, or a Ext.dom.Helper specification to use as the layout element content. The HTML content is added after the component is rendered, so the document will not contain this HTML at the time the event-render event is fired. This content is inserted into the body before any configured contentEl is appended.

Defaults to:

''

Available since: 3.4.0

setHtml ( html, [loadScripts], [callback], [scriptScope] )

Update the content area of a component.

Available since: 3.4.0

Parameters

html :  String/Object

If this component has been configured with a template via the tpl config then it will use this argument as data to populate the template. If this component was not configured with a template, the components content area will be updated via Ext.Element update.

loadScripts :  Boolean (optional)

Only legitimate when using the html configuration. Causes embedded script tags to be executed. Inline source will be executed with this Component as the scope (this reference).

Defaults to: false

callback :  Function (optional)

Only legitimate when using the html configuration. Callback to execute when scripts have finished loading.

scriptScope :  Object (optional)

The scope (this reference) in which to execute inline script elements content. Scripts with a src attribute cannot be executed with this scope.

Defaults to: 'this'

iconCls : String

One or more space separated CSS classes to be applied to the icon element. The CSS rule(s) applied should specify a background image to be used as the icon.

An example of specifying a custom icon class would be something like:

// specify the property in the config for the class:
iconCls: 'my-home-icon'

// css rule specifying the background image to be used as the icon image:
.my-home-icon {
    background-image: url(../images/my-home-icon.gif) !important;
}

In addition to specifying your own classes, you can use the font icons provided in the SDK using the following syntax:

// using Font Awesome
iconCls: 'x-fa fa-home'

// using Pictos
iconCls: 'pictos pictos-home'

Depending on the theme you're using, you may need include the font icon packages in your application in order to use the icons included in the SDK. For more information see:

Example usage:

// Example CSS rule:
.x-statusbar .x-status-custom {
    padding-left: 25px;
    background: transparent url(images/custom-icon.gif) no-repeat 3px 2px;
}

// Setting a default icon:
var sb = Ext.create('Ext.ux.statusbar.StatusBar', {
    defaultIconCls: 'x-status-custom'
});

// Changing the icon:
sb.setStatus({
    text: 'New status',
    iconCls: 'x-status-custom'
});

Defaults to:

''

id : String

The unique id of this component instance.

Use of this config should be considered carefully as this value must be unique across all existing components. Components created with an id may be accessed globally using Ext.getCmp.

Instead of using assigned ids, consider a reference config and a ViewController to respond to events and perform processing upon this Component.

Alternatively, itemId and Ext.ComponentQuery can be used to perform selector-based searching for Components analogous to DOM querying. The Ext.container.Container class contains several helpful shortcut methods to query its descendant Components by selector.

Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.

Defaults to an auto-assigned id.

Note: Valid identifiers start with a letter or underscore and are followed by (optional) additional letters, underscores, digits or hyphens.

Available since: 1.1.0

getId String

Retrieves the id of this component. Will auto-generate an id if one has not already been set.

Returns

:String

inactiveChildTabIndex : Number

DOM tabIndex attribute to set on inactive Focusable children of this container when using the "Roaming tabindex" technique. This value rarely needs to be changed from its default.

Defaults to:

-1

itemId : String

The unique id of this component instance within its container. See also the reference config.

An itemId can be used as an alternative way to get a reference to a component when no object reference is available. Instead of using an id with getCmp, use itemId with getComponent which will retrieve itemId's or id's. Since itemId's are an index to the container's internal collection, the itemId is scoped locally to the container -- avoiding potential conflicts with Ext.ComponentManager, which requires a unique id value.

var c = new Ext.panel.Panel({ //
    height: 300,
    renderTo: document.body,
    layout: 'auto',
    items: [{
        itemId: 'p1',
        title: 'Panel 1',
        height: 150
    },{
        itemId: 'p2',
        title: 'Panel 2',
        height: 150
    }]
});

p1 = c.getComponent('p1'); // not the same as Ext.getCmp()
console.log(p1);
p2 = p1.ownerCt.getComponent('p2'); // reference via a sibling
console.log(p2);

Also see id, Ext.container.Container#query, Ext.container.Container#down and Ext.container.Container#child.

Note: Valid identifiers start with a letter or underscore and are followed by (optional) additional letters, underscores, digits or hyphens.

Note: to access the container of an item see ownerCt.

Available since: 3.4.0

getItemId String

Returns the value of itemId assigned to this component, or when that is not set, returns the value of id.

Returns

:String

items : Object / Object[]

A single item, or an array of child Components to be added to this container

Unless configured with a layout, a Container simply renders child Components serially into its encapsulating element and performs no sizing or positioning upon them.

Example:

// specifying a single item
items: {...},
layout: 'fit',    // The single items is sized to fit

// specifying multiple items
items: [{...}, {...}],
layout: 'hbox', // The items are arranged horizontally

Each item may be:

If a configuration object is specified, the actual type of Component to be instantiated my be indicated by using the xtype option.

Every Component class has its own xtype.

If an xtype is not explicitly specified, the cfg-defaultType for the Container is used, which by default is usually panel.

Notes:

Ext uses lazy rendering. Child Components will only be rendered should it become necessary. Items are automatically laid out when they are first shown (no sizing is done while hidden), or in response to a method-updateLayout call.

Do not specify contentEl or html with items.

Defaults to:

undefined

Available since: 2.3.0

keyMap : Object
bindable bind

An object containing handlers for keyboard events. The property names of this object are the key name and any modifiers. The values of the properties are the descriptors of how to handle each event.

The handler descriptor can be simply the handler function(either the literal function or the method name), or it can be an object with these properties:

  • handler: The function or its name to call to handle the event.
  • scope: The this pointer context (can be "this" or "controller").
  • event: An optional override of the key event to which to listen.

Important: Calls to setKeyMap do not replace the entire keyMap but instead update the provided mappings. That is, unless null is passed as the value of the keyMap which will clear the keyMap of all entries.

Defaults to:

null

Properties

scope : String

The default scope to apply to key handlers which do not specify a scope. This is processed the same way as the scope of cfg-listeners. It defaults to the "controller", but using 'this' means that an instance method will be used.

getKeyMap : Object

Returns the value of keyMap

Returns

Object

setKeyMap (keyMap)

Sets the value of keyMap

Parameters

keyMap :  Object

keyMapEnabled : Boolean
bindable bind

Enables or disables processing keys in the keyMap. This value starts as null and if it is null when initKeyMap is called, it will automatically be set to true. Since initKeyMap is called by Ext.Component at the proper time, this is not something application code normally handles.

Defaults to:

null

getKeyMapEnabled : Boolean

Returns the value of keyMapEnabled

Returns

Boolean

setKeyMapEnabled (keyMapEnabled)

Sets the value of keyMapEnabled

Parameters

keyMapEnabled :  Boolean

keyMapTarget : String
protected pro

The name of the member that should be used to listen for keydown/keypress events. This is intended to be controlled at the class level not per instance.

Defaults to:

'el'

layout : Ext.enums.Layout / Object
bindable bind

This class assigns a default layout (layout: 'hbox' or layout: 'vbox' depending upon orientation).

Developers may override this configuration option if another layout is required. See Ext.container.Container#layout for additional information.

Defaults to:

undefined

getLayout Ext.layout.container.Container

Returns the Ext.layout.container.Container instance currently associated with this Container. If a layout has not been instantiated yet, that is done first

Returns

:Ext.layout.container.Container

The layout

setLayout ( configuration )

Reconfigures the initially configured layout.

NOTE: this method cannot be used to change the "type" of layout after the component has been rendered to the DOM. After rendering, this method can only modify the existing layout's configuration properties. The reason for this restriction is that many container layouts insert special wrapping elements into the dom, and the framework does not currently support dynamically changing these elements once rendered.

Parameters

configuration :  Object

object for the layout

liquidLayout : Boolean

Components that achieve their internal layout results using solely CSS with no JS intervention must set this to true. This allows the component to opt out of the layout run when used inside certain container layouts such as Ext.layout.container.Form and Ext.layout.container.Auto resulting in a performance gain. The following components currently use liquid layout (liquidLayout: true):

It is important to keep in mind that components using liquidLayout do not fire the following events:

In addition, liquidLayout components do not call the following template methods:

Any component that needs to fire these events or to have these methods called during its life cycle needs to set liquidLayout to false. The following example demonstrates how to enable the resize event for a Ext.form.field.TextArea:

Use caution when setting liquidLayout to false as it carries a performance penalty since it means the layout system must perform expensive DOM reads to determine the Component's size.

Defaults to:

false

listeners : Object
bindable bind

A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.

DOM events from Ext JS Ext.Component

While some Ext JS Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually only done when extra value can be added. For example the Ext.view.View's itemclick event passing the node clicked on. To access DOM events directly from a child element of a Component, we need to specify the element option to identify the Component property to add a DOM listener to:

new Ext.panel.Panel({
    width: 400,
    height: 200,
    dockedItems: [{
        xtype: 'toolbar'
    }],
    listeners: {
        click: {
            element: 'el', //bind to the underlying el property on the panel
            fn: function(){ console.log('click el'); }
        },
        dblclick: {
            element: 'body', //bind to the underlying body property on the panel
            fn: function(){ console.log('dblclick body'); }
        }
    }
});

setListeners ( listeners )

An alias for addListener. In versions prior to 5.1, listeners had a generated setter which could be called to add listeners. In 5.1 the listeners config is not processed using the config system and has no generated setter, so this method is provided for backward compatibility. The preferred way of adding listeners is to use the on method.

Parameters

listeners :  Object

The listeners

liveDrag : Boolean

True to drag the component itself. Else a lightweight version of the component will be shown (using the component's ghost() method).

Note: This config is only relevant when used with dragging implemented via Ext.util.ComponentDragger.

Defaults to:

false

loader : Ext.ComponentLoader / Object

A configuration object or an instance of a Ext.ComponentLoader to load remote content for this Component.

Ext.create('Ext.Component', {
    loader: {
        url: 'content.html',
        autoLoad: true
    },
    renderTo: Ext.getBody()
});

getLoader Ext.ComponentLoader

Gets the Ext.ComponentLoader for this Component.

Returns

:Ext.ComponentLoader

The loader instance, null if it doesn't exist.

margin : Number / String
bindable bind

Specifies the margin for this component. The margin can be a single numeric value to apply to all sides or it can be a CSS style specification for each style, for example: '10 5 3 10' (top, right, bottom, left).

setMargin ( margin )

Sets the margin on the target element.

Parameters

margin :  Number/String

The margin to set. See the margin config.

maskDefaults : Object

Default LoadMask configuration for method-setLoading.

maskElement : String

Related to the cfg-childEls configuration which specifies named properties which correspond to component sub-elements.

The name of the element property in this component to mask when masked by a LoadMask.

Defaults to null to indicate that Components cannot by default contain a LoadMask, and that any LoadMask should be rendered into the document body.

For example, Panels use "el" to indicate that the whole panel should be masked. This could be configured to be "body" so that only the body is masked and toolbars and the header are still mouse-accessible.

Defaults to:

null

maxHeight : Number
bindable bind

The maximum value in pixels which this Component will set its height to.

Warning: This will override any size management applied by layout managers.

Defaults to:

null

getMaxHeight : Number

Returns the value of maxHeight

Returns

Number

setMaxHeight (maxHeight)

Sets the value of maxHeight

Parameters

maxHeight :  Number

maxWidth : Number
bindable bind

The maximum value in pixels which this Component will set its width to.

Warning: This will override any size management applied by layout managers.

Defaults to:

null

getMaxWidth : Number

Returns the value of maxWidth

Returns

Number

setMaxWidth (maxWidth)

Sets the value of maxWidth

Parameters

maxWidth :  Number

minHeight : Number
bindable bind

The minimum value in pixels which this Component will set its height to.

Warning: This will override any size management applied by layout managers.

Defaults to:

null

getMinHeight : Number

Returns the value of minHeight

Returns

Number

setMinHeight (minHeight)

Sets the value of minHeight

Parameters

minHeight :  Number

minWidth : Number
bindable bind

The minimum value in pixels which this Component will set its width to.

Warning: This will override any size management applied by layout managers.

Defaults to:

null

getMinWidth : Number

Returns the value of minWidth

Returns

Number

setMinWidth (minWidth)

Sets the value of minWidth

Parameters

minWidth :  Number

modal : Boolean

True to make the floated component modal and mask everything behind it when displayed, false to display it without restricting access to other UI elements.

Defaults to:

false

modelValidation : Boolean

This config enables binding to your Ext.data.Model#validators. This is only processed by form fields (e.g., Ext.form.field.Text) at present, but this setting is inherited and so can be set on a parent container.

When set to true by a component or not set by a component but inherited from an ancestor container, Ext.data.Validation records are used to automatically bind validation results for any form field to which a value is bound.

While this config can be set arbitrarily high in the component hierarchy, doing so can create a lot overhead if most of your form fields do not actually rely on validators in your data model.

Using this setting for a form that is bound to an Ext.data.Model might look like this:

 {
     xtype: 'panel',
     modelValidation: true,
     items: [{
         xtype: 'textfield',
         bind: '{theUser.firstName}'
     },{
         xtype: 'textfield',
         bind: '{theUser.lastName}'
     },{
         xtype: 'textfield',
         bind: '{theUser.phoneNumber}'
     },{
         xtype: 'textfield',
         bind: '{theUser.email}'
     }]
 }

Notice that "validation" is a pseudo-association defined for all entities. See Ext.data.Model#getValidation for further details.

nameable : Boolean

Set to true for this component's name property to be tracked by its containing nameHolder.

Defaults to:

false

nameHolder : Boolean

When true child components are tracked by their name property and can be retrieved using the lookupName method.

Defaults to:

false

overCls : String

An optional extra CSS class that will be added to this component's Element when the mouse moves over the Element, and removed when the mouse moves out. This can be useful for adding customized 'active' or 'hover' styles to the component or any of its children using standard CSS rules.

Defaults to:

''

Available since: 2.3.0

overflowHandler : String

  • null - hidden overflow
  • 'scroller' to render left/right scroller buttons on either side of the breadcrumb
  • 'menu' to render the overflowing buttons as items of an overflow menu.

Defaults to:

null

overflowX : String
deprecated dep

Possible values are:

  • 'auto' to enable automatic horizontal scrollbar (Style overflow-x: 'auto').
  • 'scroll' to always enable horizontal scrollbar (Style overflow-x: 'scroll').

The default is overflow-x: 'hidden'. This should not be combined with autoScroll.

Deprecated since version 5.1.0
Use scrollable instead

overflowY : String
deprecated dep

Possible values are:

  • 'auto' to enable automatic vertical scrollbar (Style overflow-y: 'auto').
  • 'scroll' to always enable vertical scrollbar (Style overflow-y: 'scroll').

The default is overflow-y: 'hidden'. This should not be combined with autoScroll.

Deprecated since version 5.1.0
Use scrollable instead

padding : Number / String

Specifies the padding for this component. The padding can be a single numeric value to apply to all sides or it can be a CSS style specification for each style, for example: '10 5 3 10' (top, right, bottom, left).

plugins : Array / Ext.enums.Plugin / Object / Ext.plugin.Abstract

This config describes one or more plugin config objects used to create plugin instances for this component.

Plugins are a way to bundle and reuse custom functionality. Plugins should extend Ext.plugin.Abstract but technically the only requirement for a valid plugin is that it contain an init method that accepts a reference to its owner. Once a plugin is created, the owner will call the init method, passing a reference to itself. Each plugin can then call methods or respond to events on its owner as needed to provide its functionality.

This config's value can take several different forms.

The value can be a single string with the plugin's Ext.enums.Plugin:

plugins: 'cellediting',

The preferred form for multiple plugins or to configure plugins is the keyed-object form (new in version 6.5):

 plugins: {
     gridviewdragdrop: true,
     cellediting: {
         clicksToEdit: 1
     }
 },

The keys are id's as well as the default type alias.

The plugins config can also be an array of plugin aliases:

plugins: [ 'cellediting', 'gridviewdragdrop' ],

An array can also contain elements that are config objects with a ptype property holding the type alias:

 plugins: ['gridviewdragdrop', {
     ptype: 'cellediting',
     clicksToEdit: 1
 }],

Available since: 2.3.0

getPlugins
private pri

Returns an array of current fully constructed plugin instances.

publishes : String / String[] / Object
bindable bind

One or more names of config properties that this component should publish to its ViewModel. Generally speaking, only properties defined in a class config block (including ancestor config blocks and mixins) are eligible for publishing to the viewModel. Some components override this and publish their most useful configs by default.

Note: We'll discuss publishing properties not found in the config block below.

Values determined to be invalid by component (often form fields and model validations) will not be published to the ViewModel.

This config uses the cfg-reference to determine the name of the data object to place in the ViewModel. If reference is not set then this config is ignored.

By using this config and cfg-reference you can bind configs between components. For example:

 ...
     items: [{
         xtype: 'textfield',
         reference: 'somefield',  // component's name in the ViewModel
         publishes: 'value' // value is not published by default
     },{
         ...
     },{
         xtype: 'displayfield',
         bind: 'You have entered "{somefield.value}"'
     }]
 ...

Classes must provide this config as an Object:

 Ext.define('App.foo.Bar', {
     publishes: {
         foo: true,
         bar: true
     }
 });

This is required for the config system to properly merge values from derived classes.

For instances this value can be specified as a value as show above or an array or object as follows:

 {
     xtype: 'textfield',
     reference: 'somefield',
     publishes: [
         'value',
         'rawValue',
         'dirty'
     ]
 }

 // This achieves the same result as the above array form.
 {
     xtype: 'textfield',
     reference: 'somefield',
     publishes: {
         value: true,
         rawValue: true,
         dirty: true
     }
 }

In some cases, users may want to publish a property to the viewModel that is not found in a class config block. In these situations, you may utilize publishState if the property has a setter method. Let's use setFieldLabel as an example:

  setFieldLabel: function(fieldLabel) {
      this.callParent(arguments);
      this.publishState('fieldLabel', fieldLabel);
  }

With the above chunk of code, fieldLabel may now be published to the viewModel.

Defaults to:

null

Available since: 5.0.0

getPublishes : String / String[] / Object

Returns the value of publishes

Returns

String / String[] / Object

setPublishes (publishes)

Sets the value of publishes

Parameters

publishes :  String / String[] / Object

reference : String

Specifies a name for this component inside its component hierarchy. This name must be unique within its view or its Ext.app.ViewController. See the documentation in Ext.container.Container for more information about references.

Note: Valid identifiers start with a letter or underscore and are followed by zero or more additional letters, underscores or digits. References are case sensitive.

Defaults to:

null

referenceHolder : Boolean

If true, this container will be marked as being a point in the hierarchy where references to items with a specified reference config will be held. The container will automatically become a referenceHolder if a controller is specified.

See the introductory docs for Ext.container.Container for more information about references & reference holders.

Defaults to:

false

region : "north" / "south" / "east" / "west" / "center"

Defines the region inside Ext.layout.container.Border.

Possible values:

  • north - Positions component at top.
  • south - Positions component at bottom.
  • east - Positions component at right.
  • west - Positions component at left.
  • center - Positions component at the remaining space. There must be a component with region: "center" in every border layout.

Defaults to:

undefined

getRegion ( [contentBox], [local] ) : Ext.util.Region

Returns a region object that defines the area of this element.

Parameters

contentBox :  Boolean (optional)

If true a box for the content of the element is returned.

local :  Boolean (optional)

If true the element's left and top relative to its offsetParent are returned instead of page x/y.

Returns

:Ext.util.Region

A Region containing "top, left, bottom, right" properties.

renderConfig : Object

renderConfig wraps configs that do not get applied until after the component is rendered. Unlike normal config system properties, renderConfigs use a special setter method to store values on the instance instead of running the apply and update methods if it is called before the component is rendered. Then, after the component has been rendered, these values are processed by the normal apply and update method for the config.

This means that calling the get method for the config prior to render will return whatever raw value has been set, while calling the getter after render will return the value after processing by the config's apply method. If this distinction needs to be made, it is the caller's responsibility to check for the rendered state and handle such intermediate config values.

renderData : Object

The data used by renderTpl in addition to the following property values of the component:

  • id
  • ui
  • uiCls
  • baseCls
  • componentCls
  • frame

See renderSelectors and cfg-childEls for usage examples.

renderSelectors : Object
deprecated dep

An object containing properties specifying CSS selectors which identify child elements created by the render process.

After the Component's internal structure is rendered according to the renderTpl, this object is iterated through, and the found Elements are added as properties to the Component using the renderSelector property name.

For example, a Component which renders a title and description into its element:

 Ext.create('Ext.Component', {
     renderTo: Ext.getBody(),
     renderTpl: [
         '<h1 class="title">{title}</h1>',
         '<p>{desc}</p>'
     ],
     renderData: {
         title: "Error",
         desc: "Something went wrong"
     },
     renderSelectors: {
         titleEl: 'h1.title',
         descEl: 'p'
     },
     listeners: {
         afterrender: function(cmp){
             // After rendering the component will have a titleEl and descEl properties
             cmp.titleEl.setStyle({color: "red"});
         }
     }
 });

The use of renderSelectors is deprecated (for performance reasons). The above code should be refactored into something like this:

 Ext.create('Ext.Component', {
     renderTo: Ext.getBody(),
     renderTpl: [
         '<h1 class="title" id="{id}-titleEl" data-ref="titleEl">{title}</h1>',
         '<p id="{id}-descEl" data-ref="descEl">{desc}</p>'
     ],
     renderData: {
         title: "Error",
         desc: "Something went wrong"
     },
     childEls: [
         'titleEl',
         'descEl'
     ]
 });

To use childEls yet retain the use of selectors (which remains as expensive as renderSelectors):

 Ext.create('Ext.Component', {
     renderTo: Ext.getBody(),
     renderTpl: [
         '<h1 class="title">{title}</h1>',
         '<p>{desc}</p>'
     ],
     renderData: {
         title: "Error",
         desc: "Something went wrong"
     },
     childEls: {
         titleEl: { selectNode: 'h1.title' },
         descEl: { selectNode: 'p' }
     }
 });

Deprecated since version 5.0
Use cfg-childEls instead.

renderTo : String / HTMLElement / Ext.dom.Element

Specify the id of the element, a DOM element or an existing Element that this component will be rendered into.

Notes:

Do not use this option if the Component is to be a child item of a Ext.container.Container. It is the responsibility of the Ext.container.Container's layout manager to render and manage its child items.

When using this config, a call to render() is not required.

See also: method-render.

Available since: 2.3.0

renderTpl : Ext.XTemplate / String / String[]

An Ext.XTemplate used to create the internal structure inside this Component's encapsulating Element.

You do not normally need to specify this. For the base classes Ext.Component and Ext.container.Container, this defaults to null which means that they will be initially rendered with no internal structure; they render their Element empty. The more specialized classes with complex DOM structures provide their own template definitions.

This is intended to allow the developer to create application-specific utility Components with customized internal structure.

Upon rendering, any created child elements may be automatically imported into object properties using the renderSelectors and cfg-childEls options.

Defaults to:

'<tpl if="hasTabGuard">{% this.renderTabGuard(out, values, \'before\'); %}</tpl>' + '{% this.renderContainer(out,values) %}' + '<tpl if="hasTabGuard">{% this.renderTabGuard(out, values, \'after\'); %}</tpl>'

resetFocusPosition : Boolean

When true, FocusableContainer will reset last focused position whenever focus leaves the container. Subsequent tabbing into the container will always focus the first eligible child item.

When false, subsequent tabbing into the container will focus the child item that was last focused before.

Defaults to:

false

resizable : Boolean / Object

Specify as true to apply a Ext.resizer.Resizer to this Component after rendering.

May also be specified as a config object to be passed to the constructor of Ext.resizer.Resizer to override any defaults. By default the Component passes its minimum and maximum size, and uses Ext.resizer.Resizer#dynamic: false

resizeHandles : String

A valid Ext.resizer.Resizer handles config string. Only applies when resizable = true.

Defaults to:

'all'

saveDelay : Number

A buffer to be applied if many state events are fired within a short period.

Defaults to:

100

scrollable : Boolean / String / Object
bindable bind

Configuration options to make this Component scrollable. Acceptable values are:

  • true to enable auto scrolling.
  • false (or null) to disable scrolling - this is the default.
  • x or horizontal to enable horizontal scrolling only
  • y or vertical to enable vertical scrolling only

Also accepts a configuration object for a Ext.scroll.Scroller if if advanced configuration is needed.

The getter for this config returns the Ext.scroll.Scroller instance. You can use the Scroller API to read or manipulate the scroll position:

// scrolls the component to 5 on the x axis and 10 on the y axis
component.getScrollable().scrollTo(5, 10);

Defaults to:

null

getScrollable : Boolean / String / Object

Returns the value of scrollable

Returns

Boolean / String / Object

setScrollable (scrollable)

Sets the value of scrollable

Parameters

scrollable :  Boolean / String / Object

session : Boolean / Object / Ext.data.Session
bindable bind

If provided this creates a new Session instance for this component. If this is a Container, this will then be inherited by all child components.

To create a new session you can specify true:

 Ext.create({
     xtype: 'viewport',
     session: true,

     items: [{
         ...
     }]
 });

Alternatively, a config object can be provided:

 Ext.create({
     xtype: 'viewport',
     session: {
         ...
     },

     items: [{
         ...
     }]
 });

Defaults to:

null

getSession : Boolean / Object / Ext.data.Session

Returns the value of session

Returns

Boolean / Object / Ext.data.Session

setSession (session)

Sets the value of session

Parameters

session :  Boolean / Object / Ext.data.Session

shadow : String / Boolean

Specifies whether the floating component should be given a shadow. Set to true to automatically create an Ext.Shadow, or a string indicating the shadow's display Ext.Shadow#mode. Set to false to disable the shadow.

Defaults to:

'sides'

shadowOffset : Number

Number of pixels to offset the shadow.

shareableName : Boolean

Set to true to allow this component's name to be shared by other items in the same nameHolder. Such items will be returned in an array from lookupName.

Defaults to:

false

shim : Boolean

true to enable an iframe shim for this Component to keep windowed objects from showing through.

shrinkWrap : Boolean / Number

The possible values for shrinkWrap are:

  • 0 (or false): Neither width nor height depend on content.
  • 1: Width depends on content (shrink wraps), but height does not.
  • 2: Height depends on content (shrink wraps), but width does not.
  • 3 (or true): Both width and height depend on content (shrink wrap).

In CSS terms, shrink-wrap width is analogous to an inline-block element as opposed to a block-level element.

Non-Panel Components

The shrinkWrap config is a class-level config and should be used when defining a subclass. It is not intended to be set as a config on instances of a given component.

For non-Panel components, shrinkWrap is a descriptive config only. It should be set when defining your own custom class including the DOM elements used to construct the component. The shrinkWrap property does not itself apply styling on the component elements. Rather, it should describe the CSS styling you've applied to your custom component (refer to the numeric matrix above).

When a component is owned by a container the layout of that container will inspect the component's shrinkWrap property during layout. The layout then uses the content-wrapping policy described by shrinkWrap to correctly size and position the container's child items.

Defaults to:

2

stateEvents : String[]

An array of events that, when fired, should trigger this object to save its state. stateEvents defaults to the stateEvents associated with the component you are using. Any events you statically set will be appended to that list. stateEvents may be any type of event supported by this object, including browser or custom events (e.g., ['click', 'customerchange']).

See stateful for an explanation of saving and restoring object state. By default the following stateEvents are added:

stateful : Boolean / Object
bindable bind

A flag which causes the object to attempt to restore the state of internal properties from a saved state on startup. The object must have a stateId for state to be managed.

Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a object.

For state saving to work, the state manager's provider must have been set to an implementation of Ext.state.Provider which overrides the set and get methods to save and recall name/value pairs. A built-in implementation, Ext.state.CookieProvider is available.

To set the state provider for the current page:

Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
    expires: new Date(new Date().getTime()+(1000*60*60*24*7)), // 7 days from now
}));

A stateful object attempts to save state when one of the events listed in the stateEvents configuration fires.

To save state, a stateful object first serializes its state by calling getState.

The Component base class implements getState to save its width and height within the state only if they were initially configured, and have changed from the configured value.

The Panel class saves its collapsed state in addition to that.

The Grid class saves its column state and store state (sorters and filters and grouper) in addition to its superclass state.

If there is more application state to be save, the developer must provide an implementation which first calls the superclass method to inherit the above behaviour, and then injects new properties into the returned object.

The value yielded by getState is passed to Ext.state.Manager#set which uses the configured Ext.state.Provider to save the object keyed by the stateId.

During construction, a stateful object attempts to restore its state by calling Ext.state.Manager#get passing the stateId

The resulting object is passed to applyState*. The default implementation of applyState simply copies properties into the object, but a developer may override this to support restoration of more complex application state.

You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events. In some simple cases, passing an object for the stateful config may suffice. If an object is provided, the properties of that object are used to include or exclude stateful properties returned by getState. For example:

 stateful: {
     height: false, // never persist the height
     width: true    // always persist the width
 }

The above is roughly equivalent to the following:

 getState: function () {
     var state = this.callParent();

     delete state.height;
     state.width = this.width;

     return state;
 }

Defaults to:

false

getStateful : Boolean / Object

Returns the value of stateful

Returns

Boolean / Object

setStateful (stateful)

Sets the value of stateful

Parameters

stateful :  Boolean / Object

stateId : String

The unique id for this object to use for state management purposes.

See stateful for an explanation of saving and restoring state.

getStateId String
private pri

Gets the state id for this object.

Returns

:String

The 'stateId' or the implicit 'id' specified by component configuration.

statusAlign : String

The alignment of the status element within the overall StatusBar layout. When the StatusBar is rendered, it creates an internal div containing the status text and icon. Any additional Toolbar items added in the StatusBar's cfg-items config, or added via method-add or any of the supported add* methods, will be rendered, in added order, to the opposite side. The status element is greedy, so it will automatically expand to take up all sapce left over by any other items. Example usage:

// Create a left-aligned status bar containing a button,
// separator and text item that will be right-aligned (default):
Ext.create('Ext.Panel', {
    title: 'StatusBar',
    // etc.
    bbar: Ext.create('Ext.ux.statusbar.StatusBar', {
        defaultText: 'Default status text',
        id: 'status-id',
        items: [{
            text: 'A Button'
        }, '-', 'Plain Text']
    })
});

// By adding the statusAlign config, this will create the
// exact same toolbar, except the status and toolbar item
// layout will be reversed from the previous example:
Ext.create('Ext.Panel', {
    title: 'StatusBar',
    // etc.
    bbar: Ext.create('Ext.ux.statusbar.StatusBar', {
        defaultText: 'Default status text',
        id: 'status-id',
        statusAlign: 'right',
        items: [{
            text: 'A Button'
        }, '-', 'Plain Text']
    })
});

style : String / Object
bindable bind

A custom style specification to be applied to this component's Element. Should be a valid argument to Ext.dom.Element#applyStyles.

new Ext.panel.Panel({
    title: 'Some Title',
    renderTo: Ext.getBody(),
    width: 400, height: 300,
    layout: 'form',
    items: [{
        xtype: 'textarea',
        style: {
            width: '95%',
            marginBottom: '10px'
        }
    },
    new Ext.button.Button({
        text: 'Send',
        minWidth: '100',
        style: {
            marginBottom: '10px'
        }
    })
    ]
});

Available since: 1.1.0

setStyle ( property, [value] ) : Ext.Component
chainable ch

var name = Ext.create({
    xtype: 'component',
    renderTo: Ext.getBody(),
    html: 'Phineas Flynn'
});

// two-param syntax
name.setStyle('color', 'white');

bindable bind

DOM tabIndex attribute for this component's focusEl.

getTabIndex Number

Return the actual tabIndex for this Focusable.

Returns

:Number

tabIndex attribute value

setTabIndex ( newTabIndex )

Set the tabIndex property for this Focusable. If the focusEl is available, set tabIndex attribute on it, too.

Parameters

newTabIndex :  Number

new tabIndex to set

text : String
bindable bind

:Ext.ux.statusbar.StatusBar

this

toFrontOnShow : Boolean

True to automatically call toFront when the method-show method is called on an already visible, floating component.

Defaults to:

true

touchAction : Object
bindable bind

Emulates the behavior of the CSS touch-action property in a cross-browser compatible manner.

Keys in this object are touch action names, and values are false to disable a touch action or true to enable it. Accepted keys are:

  • panX
  • panY
  • pinchZoom
  • doubleTapZoom

All touch actions are enabled (true) by default, so it is usually only necessary to specify which touch actions to disable. For example, the following disables only horizontal scrolling and pinch-to-zoom on the component's main element:

touchAction: {
    panX: false,
    pinchZoom: false
}

Touch actions can be specified on child elements using the child element name, for example:

// disables horizontal scrolling on the main element, and double-tap-zoom
// on the child element named "body"
touchAction: {
    panY: false
    body: {
        doubleTapZoom: false
    }
}

The primary motivation for setting the touch-action of an element is to prevent the browser's default handling of a gesture such as pinch-to-zoom, or drag-to-scroll, so that the application can implement its own handling of that gesture on the element. Suppose, for example, a component has a custom drag handler on its element and wishes to prevent horizontal scrolling of its container while it is being dragged:

Ext.create('Ext.Component', {
    touchAction: {
        panX: false
    },
    listeners: {
        drag: function(e) {
            // implement drag logic
        }
    }
});

Defaults to:

null

trackMenus : Boolean

If true, when a toolbar button has a menu open, then mousing over other toolbar buttons opens their menus.

Defaults to:

true

twoWayBindable : String / String[] / Object
bindable bind

This object holds a map of config properties that will update their binding as they are modified. For example, value is a key added by form fields. The form of this config is the same as publishes.

This config is defined so that updaters are not created and added for all bound properties since most cannot be modified by the end-user and hence are not appropriate for two-way binding.

Defaults to:

null

getTwoWayBindable : String / String[] / Object

Returns the value of twoWayBindable

Returns

String / String[] / Object

setTwoWayBindable (twoWayBindable)

Sets the value of twoWayBindable

Parameters

twoWayBindable :  String / String[] / Object

ui : String
bindable bind

A UI style for a component.

Defaults to:

'default'

setUI ( ui )

Sets the UI for the component. This will remove any existing UIs on the component. It will also loop through any uiCls set on the component and rename them so they include the new UI.

Parameters

ui :  String

The new UI for the component.

uiCls : String[]
private pri

An array of of classNames which are currently applied to this component.

Defaults to:

[]

userCls : String / String[]
bindable bind

One or more CSS classes to add to the component's primary element. This config is intended solely for use by the component instantiator (the "user"), not by derived classes.

For example:

 items: [{
     xtype: 'button',
     userCls: 'my-button'
 ...
 }]

Defaults to:

null

getUserCls : String / String[]

Returns the value of userCls

Returns

String / String[]

setUserCls (userCls)

Sets the value of userCls

Parameters

userCls :  String / String[]

vertical : Boolean

Set to true to make the toolbar vertical. The layout will become a vbox.

Defaults to:

false

viewModel : String / Object / Ext.app.ViewModel
bindable bind

The ViewModel is a data provider for this component and its children. The data contained in the ViewModel is typically used by adding bind configs to the components that want present or edit this data.

When set, the ViewModel is created and links to any inherited viewModel instance from an ancestor container as the "parent". The ViewModel hierarchy, once established, only supports creation or destruction of children. The parent of a ViewModel cannot be changed on the fly.

If this is a root-level ViewModel, the data model connection is made to this component's associated Ext.data.Session. This is determined by calling getInheritedSession.

Defaults to:

null

getViewModel : String / Object / Ext.app.ViewModel

Returns the value of viewModel

Returns

String / Object / Ext.app.ViewModel

setViewModel (viewModel)

Sets the value of viewModel

Parameters

viewModel :  String / Object / Ext.app.ViewModel

weight : Number

A value to control how Components are laid out in a Ext.layout.container.Border layout or as docked items.

In a Border layout, this can control how the regions (not the center) region lay out if the west or east take full height or if the north or south region take full width. Also look at the Ext.layout.container.Border#regionWeights on the Border layout. An example to show how you can take control of this is:

Ext.create('Ext.container.Viewport', {
    layout      : 'border',
    defaultType : 'panel',
    items       : [
        {
            region : 'north',
            title  : 'North',
            height : 100
        },
        {
            region : 'south',
            title  : 'South',
            height : 100,
            weight : -25
        },
        {
            region : 'west',
            title  : 'West',
            width  : 200,
            weight : 15
        },
        {
            region : 'east',
            title  : 'East',
            width  : 200
        },
        {
            region : 'center',
            title  : 'center'
        }
    ]
});

If docked items, the weight will order how the items are laid out. Here is an example to put a Ext.toolbar.Toolbar above a Ext.panel.Panel's header:

Ext.create('Ext.panel.Panel', {
    renderTo    : document.body,
    width       : 300,
    height      : 300,
    title       : 'Panel',
    html        : 'Panel Body',
    dockedItems : [
        {
            xtype : 'toolbar',
            items : [
                {
                    text : 'Save'
                }
            ]

null

width : Number / String
bindable bind

The width of this component. A numeric value will be interpreted as the number of pixels; a string value will be treated as a CSS value with units.

getWidth Number

Gets the current width of the component's underlying element.

Returns

:Number

setWidth ( width ) : Ext.Component

Sets the width of the component. This method fires the resize event.

Parameters

width :  Number

The new width to set. This may be one of:

  • A Number specifying the new width in pixels.
  • A String used to set the CSS width style.
  • undefined to leave the width unchanged.
  • null to clear the width.

Returns

:Ext.Component

xtype : Ext.enums.Widget

Note: Only applies to Ext.Component derived classes when used as a config in Ext.define.

This property provides a shorter alternative to creating objects than using a full class name. Using xtype is the most common way to define component instances, especially in a container. For example, the items in a form containing text fields could be created explicitly like so:

 items: [
     Ext.create('Ext.form.field.Text', {
         fieldLabel: 'Foo'
     }),
     Ext.create('Ext.form.field.Text', {
         fieldLabel: 'Bar'
     }),
     Ext.create('Ext.form.field.Number', {
         fieldLabel: 'Num'
     })
 ]

But by using xtype, the above becomes:

 items: [
     {
         xtype: 'textfield',
         fieldLabel: 'Foo'
     },
     {
         xtype: 'textfield',
         fieldLabel: 'Bar'
     },
     {
         xtype: 'numberfield',
         fieldLabel: 'Num'
     }
 ]

When the xtype is common to many items, Ext.container.Container#defaultType is another way to specify the xtype for all items that don't have an explicit xtype:

 defaultType: 'textfield',
 items: [
     { fieldLabel: 'Foo' },
     { fieldLabel: 'Bar' },
     { fieldLabel: 'Num', xtype: 'numberfield' }
 ]

Each member of the items array is now just a "configuration object". These objects are used to create and configure component instances. A configuration object can be manually used to instantiate a component using Ext#widget:

 var text1 = Ext.create('Ext.form.field.Text', {
     fieldLabel: 'Foo'
 });

 // or alternatively:

 var text1 = Ext.widget({
     xtype: 'textfield',
     fieldLabel: 'Foo'
 });

This conversion of configuration objects into instantiated components is done when a container is created as part of its {Ext.container.AbstractContainer#initComponent} process. As part of the same process, the items array is converted from its raw array form into a Ext.util.MixedCollection instance.

You can define your own xtype on a custom Ext.Component by specifying the xtype property in Ext#define. For example:

Ext.define('MyApp.PressMeButton', {
    extend: 'Ext.button.Button',
    xtype: 'pressmebutton',
    text: 'Press Me'
});

Care should be taken when naming an xtype in a custom component because there is a single, shared scope for all xtypes. Third part components should consider using a prefix to avoid collisions.

Ext.define('Foo.form.CoolButton', {
    extend: 'Ext.button.Button',
    xtype: 'ux-coolbutton',
    text: 'Cool!'
});

See Ext.enums.Widget for list of all available xtypes.

properties

Instance Properties

$className
private pri

Defaults to:

'Ext.Base'

$configPrefixed : Boolean
private pri

The value true causes config values to be stored on instances using a property name prefixed with an underscore ("_") character. A value of false stores config values as properties using their exact name (no prefix).

Defaults to:

true

Available since: 5.0.0

$configStrict : Boolean
private pri

The value true instructs the initConfig method to only honor values for properties declared in the config block of a class. When false, properties that are not declared in a config block will be placed on the instance.

Defaults to:

true

Available since: 5.0.0

$configTransforms : Object / Array
private pri

A prototype-chained object storing transform method names and priorities stored on the class prototype. On first instantiation, this object is converted into an array that is sorted by priority and stored on the constructor.

Defaults to:

{}

$eventOptions
private pri

Matches options property names within a listeners specification object - property names which are never used as event names.

Defaults to:

{
    scope: 1,
    delay: 1,
    buffer: 1,
    onFrame: 1,
    single: 1,
    args: 1,
    destroyable: 1,
    priority: 1,
    order: 1
}

$vetoClearingPrototypeOnDestroy
private pri

We don't want the base destructor to clear the prototype because our destroyObservable handler must be called the very last. It will take care of the prototype after completing Observable destruction sequence.

Defaults to:

true

_applyDefaultsOptions
private pri

Defaults to:

{
    defaults: true,
    strict: false
}

_isLayoutRoot : Boolean
protected pro

Setting this property to true causes the isLayoutRoot method to return true and stop the search for the top-most component for a layout.

Defaults to:

false

_renderState : Number
readonly ro private pri

This property holds one of the following values during the render process:

  • 0 - The component is not rendered.
  • 1 - The component has fired beforerender and is about to call beforeRender. The component has just started rendering.
  • 2 - The component has finished the beforeRender process and is about to call onRender. This is when rendering is set to true.
  • 3 - The component has started onRender. This is when rendered is set to true.
  • 4 - The component has finished its afterrender process.

Defaults to:

0

Available since: 5.0.0

allowDomMove
private pri

Defaults to:

true

ariaEl : String
readonly ro private pri

The name of the Component property that holds a reference to the Element that serves as that Component's ARIA element. This property will be replaced with the actual Element reference after rendering.

Most of the simple Components will have their main element as ariaEl.

Defaults to:

'el'

Available since: 6.0.0

ariaRenderAttributes : Object
private pri

Instance specific ARIA attributes to render into Component's ariaEl. This object is only used during rendering, and is discarded afterwards.

ariaRole : String

ARIA role for this Component, defaults to no role. With no role, no other ARIA attributes are set.

Defaults to:

'presentation'

autoGenId : Boolean
private pri

true indicates an id was auto-generated rather than provided by configuration.

Defaults to:

false

borderBoxCls
private pri

Defaults to:

Ext.baseCSSPrefix + 'border-box'

captureArgs
private pri

Defaults to:

Super.captureArgs

clearPropertiesOnDestroy : Boolean / "async"
protected pro

Setting this property to false will prevent nulling object references on a Class instance after destruction. Setting this to "async" will delay the clearing for approx 50ms.

Defaults to:

true

Available since: 6.2.0

clearPrototypeOnDestroy : Boolean
private pri

Setting this property to true will result in setting the object's prototype to null after the destruction sequence is fully completed. After that, most attempts at calling methods on the object instance will result in "method not defined" exception. This can be very helpful with tracking down otherwise hard to find bugs like runaway Ajax requests, timed functions not cleared on destruction, etc.

Note that this option can only work in browsers that support Object.setPrototypeOf method, and is only available in debugging mode.

Defaults to:

false

Available since: 6.2.0

componentLayoutCounter : Number
private pri

The number of component layout calls made on this object.

Defaults to:

0

containsFocus : Boolean
readonly ro

true if this currently focused element is within this Component's or Container's hierarchy. This property is set separately from hasFocus, and can be true when hasFocus is false.

Examples:

  • Text field with input element focused would be: focusable: true, hasFocus: true, containsFocus: true

  • Date field with drop-down picker currently focused would be: focusable: true, hasFocus: false, containsFocus: true

  • Form Panel with a child input field currently focused would be: focusable: false, hasFocus: false, containsFocus: true

See also hasFocus.

Defaults to:

false

contentPaddingProperty : String

The name of the padding property that is used by the layout to manage padding. See managePadding

Defaults to:

'padding'

defaultBindProperty : String

This property is used to determine the property of a bind config that is just the value. For example, if defaultBindProperty="value", then this shorthand bind config:

 bind: '{name}'

Is equivalent to this object form:

 bind: {
     value: '{name}'
 }

The defaultBindProperty is set to "value" for form fields and to "store" for grids and trees.

Defaults to:

'html'

deferLayouts
private pri

Defaults to:

false

destroyed : Boolean

This property is set to true after the destroy method is called.

Defaults to:

false

eventsSuspended
private pri

Initial suspended call count. Incremented when suspendEvents is called, decremented when resumeEvents is called.

Defaults to:

0

floating : Boolean
readonly ro private pri

The value true indicates that this Component is floating.

floatingItems : Ext.util.MixedCollection

The MixedCollection containing all the floating child items of this container. Will be undefined if there are no floating child items.

Available since: 4.1.0

floatParent : Ext.container.Container
readonly ro

Only present for cfg-floating Components which were inserted as child items of Containers.

There are other similar relationships such as the Ext.button.Button which activates a menu, or the Ext.menu.Item which activated a submenu, or the Ext.grid.column.Column which activated the column menu.

These differences are abstracted away by the up method.

Floating Components that are programmatically rendered will not have a floatParent property.

See cfg-floating and zIndexManager

focusable : Boolean
readonly ro

true for keyboard interactive Components or Widgets, false otherwise. For Containers, this property reflects interactiveness of the Container itself, not its children. See isFocusable.

Note: It is not enough to set this property to true to make a component keyboard interactive. You also need to make sure that the component's focusEl is reachable via Tab key (tabbable). See also tabIndex.

Defaults to:

false

focusableContainerEl : String / Ext.dom.Element

The name of the element that FocusableContainer should bind its keyboard handler to. Similar to ariaEl, this name is resolved to the Ext.dom.Element instance after rendering.

Defaults to:

"el"

focusClsEl : Ext.dom.Element

The element that will have the focusCls applied when component's focusEl is focused.

focusEl : Ext.dom.Element

The element that will be focused when focus method is called on this component. Usually this is the same element that receives focus via mouse clicks, taps, and pressing Tab key.

Defaults to:

'el'

frameSize : Object
readonly ro

Indicates the width of any framing elements which were added within the encapsulating element to provide graphical, rounded borders. See the frame config. This property is null if the component is not framed.

This is an object containing the frame width in pixels for all four sides of the Component containing the following properties:

Defaults to:

null

Properties

top : Number

The width of the top framing element in pixels.

Defaults to: 0

right : Number

The width of the right framing element in pixels.

Defaults to: 0

bottom : Number

The width of the bottom framing element in pixels.

Defaults to: 0

left : Number

The width of the left framing element in pixels.

Defaults to: 0

width : Number

The total width of the left and right framing elements in pixels.

Defaults to: 0

height : Number

The total height of the top and right bottom elements in pixels.

Defaults to: 0

hasFocus : Boolean
readonly ro

true if this component's focusEl is focused. See also containsFocus.

Defaults to:

false

hasListeners : Object
readonly ro

This object holds a key for any event that has a listener. The listener may be set directly on the instance, or on its class or a super class (via observe) or on the Ext.app.EventBus. The values of this object are truthy (a non-zero number) and falsy (0 or undefined). They do not represent an exact count of listeners. The value for an event is truthy if the event must be fired and is falsy if there is no need to fire the event.

The intended use of this property is to avoid the expense of fireEvent calls when there are no listeners. This can be particularly helpful when one would otherwise have to call fireEvent hundreds or thousands of times. It is used like this:

 if (this.hasListeners.foo) {
     this.fireEvent('foo', this, arg1);
 }

horizontalPosProp
private pri

Defaults to:

'left'

layoutCounter : Number
private pri

The number of container layout calls made on this object.

Defaults to:

0

layoutSuspendCount
private pri

Defaults to:

0

maskOnDisable : Boolean

This is an internal flag that you use when creating custom components. By default this is set to true which means that every component gets a mask when it's disabled. Components like FieldContainer, FieldSet, Field, Button, Tab override this property to false since they want to implement custom disable logic.

Defaults to:

true

ownerCt : Ext.container.Container
readonly ro

This Component's owner Ext.container.Container (is set automatically when this Component is added to a Container).

Important. This is not a universal upwards navigation pointer. It indicates the Container which owns and manages this Component if any. There are other similar relationships such as the Ext.button.Button which activates a menu, or the Ext.menu.Item which activated a submenu, or the Ext.grid.column.Column which activated the column menu.

These differences are abstracted away by the up method.

Note: to access items within the Container see itemId.

rendered : Boolean
readonly ro

Indicates whether or not the component has been rendered.

Defaults to:

false

Available since: 1.1.0

rootCls

scrollerCls
private pri

Defaults to:

Ext.baseCSSPrefix + 'scroll-scroller'

scrollFlags : Object
readonly ro private pri

An object property which provides unified information as to which dimensions are scrollable based upon the scrollable settings (And for views of trees and grids, the owning panel's scroll setting).

Note that if you set overflow styles using the style config or bodyStyle config, this object does not include that information. Use scrollable if you need to access these flags.

self : Ext.Class
protected pro

Get the reference to the current class from which this object was instantiated. Unlike Ext.Base#statics, this.self is scope-dependent and it's meant to be used for dynamic inheritance. See Ext.Base#statics for a detailed comparison

Ext.define('My.Cat', {
    statics: {
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        alert(this.self.speciesName); // dependent on 'this'

    }
});

var cat = new My.Cat();                     // alerts 'Cat'
var snowLeopard = new My.SnowLeopard();     // alerts 'Snow Leopard'

var clone = snowLeopard.clone();
alert(Ext.getClassName(clone));             // alerts 'My.SnowLeopard'

Defaults to:

synthetic : Boolean
private pri

This property is true if the component was created internally by the framework and is not explicitly user-defined. This is set for such things as Splitter instances managed by border and box layouts.

Defaults to:

tabGuardAfterEl : Ext.dom.Element
private pri

This element reference is generated when tabGuard is true. This element is generated after all dockedItems in the DOM.

Available since: 6.0.0

tabGuardAfterIndex : Number
private pri

The tabIndex attribute value to assign to the "after" tab guard element. Default is undefined for automatic detection from the DOM.

Available since: 6.2.0

tabGuardBeforeEl : Ext.dom.Element
private pri

This element reference is generated when tabGuard is true. This element is generated before all dockedItems in the DOM.

Available since: 6.0.0

tabGuardBeforeIndex : Number
private pri

The tabIndex attribute value to assign to the "before" tab guard element. Default is undefined for automatic detection from the DOM.

Available since: 6.2.0

tabGuardElements : Object
private pri

Read only object containing property names for tab guard elements, keyed by position.

Defaults to:

{
    before: 'tabGuardBeforeEl',
    after: 'tabGuardAfterEl'
}

Available since: 6.2.0

tabGuardTpl : String / String[] / Ext.XTemplate
private pri

This template is used to generate the tabGuard elements. It is used once per element (see tabGuardBeforeEl and tabGuardAfterEl).

Defaults to:

// We use span instead of div because of IE bug/misfeature: it will focus
// block elements upon clicking or calling node.focus() regardless of
// tabIndex attribute. It doesn't do that with inline elements, hence span.
'<span id="{id}-{tabGuardEl}" data-ref="{tabGuardEl}" aria-hidden="true"' + ' class="' + Ext.baseCSSPrefix + 'tab-guard ' + Ext.baseCSSPrefix + 'tab-guard-{tabGuardPosition}"' + ' style="width:0px;height:0px;">' + '</span>'

Available since: 6.0.0

validRefRe : RegExp
private pri

Regular expression used for validating reference values.

Defaults to:

/^[a-z_][a-z0-9_]*$/i

zIndexManager : Ext.ZIndexManager
readonly ro

Only present for floating Components after they have been rendered.

A reference to the ZIndexManager which is managing this Component's z-index.

The Ext.ZIndexManager maintains a stack of floating Component z-indices, and also provides a single modal mask which is insert just beneath the topmost visible modal floating Component.

Floating Components may be brought to the front or sent to the back of the z-index stack.

This defaults to the global Ext.WindowManager for floating Components that are programatically rendered.

For floating Components that are added to a Container, the ZIndexManager is acquired from the first ancestor Container found that is floating. If no floating ancestor is found, the global Ext.WindowManager is used.

See Ext.Component#cfg-floating and zIndexParent

zIndexParent : Ext.container.Container
readonly ro

Only present for Ext.Component#cfg-floating Components which were inserted as child items of Containers, and which have a floating Container in their containment ancestry.

For Ext.Component#cfg-floating Components which are child items of a Container, the zIndexParent will be a floating ancestor Container which is responsible for the base z-index value of all its floating descendants. It provides a Ext.ZIndexManager which provides z-indexing services for all its descendant floating Components.

Floating Components that are programmatically rendered will not have a zIndexParent property.

For example, the dropdown Ext.view.BoundList of a ComboBox which is in a Window will have the Window as its zIndexParent, and will always show above that Window, wherever the Window is placed in the z-index stack.

See Ext.Component#cfg-floating and zIndexManager

addListener ( eventName, [fn], [scope], [options], [order] ) : Object
chainable ch

The on method is shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("itemclick", this.onItemClick, this);

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

myGridPanel.on({
    cellclick: this.onCellClick,
    select: this.onSelect,
    viewready: this.onViewReady,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellclick: {fn: this.onCellClick, scope: this, single: true},
    viewready: {fn: panel.onViewReady, scope: panel}
});

Names of methods in a specified scope may also be used:

myGridPanel.on({
    cellclick: {fn: 'onCellClick', scope: this, single: true},
    viewready: {fn: 'onViewReady', scope: panel}
});

Parameters

eventName :  String/Object

The name of the event to listen for. May also be an object who's property names are event names.

fn :  Function/String (optional)

The method the event invokes or the name of the method within the specified scope. Will be called with arguments given to Ext.util.Observable#fireEvent plus the options parameter described below.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

An object containing handler configuration.

Note: The options object will also be passed as the last argument to every event handler.

This object may contain any of the following properties:

scope :  Object

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

delay :  Number

The number of milliseconds to delay the invocation of the handler after the event fires.

single :  Boolean

True to add a handler to handle just the next firing of the event, and then remove itself.

buffer :  Number

Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

onFrame :  Number

Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.

target :  Ext.util.Observable

Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

element :  String

This option is only valid for listeners bound to Ext.Component. The name of a Component property which references an Ext.dom.Element to add a listener to.

This option is useful during Component construction to add DOM event listeners to elements of Ext.Component which will exist only after the Component is rendered.

For example, to add a click listener to a Panel's body:

  var panel = new Ext.panel.Panel({
      title: 'The title',
      listeners: {
          click: this.handlePanelClick,
          element: 'body'
      }
  });

In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.

 panel.body.un(...)

delegate :  String (optional)

A simple selector to filter the event target or look for a descendant of the target.

The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

See the delegate example below.

capture :  Boolean (optional)

When set to true, the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase.

The capture option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

stopPropagation :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopPropagation on the event object before firing the handler.

preventDefault :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call preventDefault on the event object before firing the handler.

stopEvent :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopEvent on the event object before firing the handler.

args :  Array (optional)

Optional set of arguments to pass to the handler function before the actual fired event arguments. For example, if args is set to ['foo', 42], the event handler function will be called with an arguments list like this:

 handler('foo', 42, <actual event arguments>...);

destroyable :  Boolean (optional)

When specified as true, the function returns a destroyable object. An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un; particularly when removing multiple listeners. NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config.

Defaults to:

false

priority :  Number (optional)

An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.

order :  String (optional)

A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:

  • 'before': equal to a priority of 100
  • 'current': equal to a priority of 0 or default priority
  • 'after': equal to a priority of -100

Defaults to:

'current'

order :  String (optional)

A shortcut for the order event option. Provided for backward compatibility. Please use the priority event option instead.

Defaults to: 'current'

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners =  = myButton.on({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

addManagedListener ( item, ename, [fn], [scope], [options] ) : Object

The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.

Example:

Ext.define('Foo', {
    extend: 'Ext.Component',

    initComponent: function () {
        this.addManagedListener(MyApp.SomeSharedMenu, 'show', this.doSomething);
        this.callParent();
    }
});

As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.

As of version 5.1 it is no longer necessary to use this method in most cases because listeners are automatically managed if the scope object provided to addListener is an Observable instance. However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item to which to add a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function/String (optional)

If the ename parameter was an event name, this is the handler function or the name of a method on the specified scope.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

options :  Object (optional)

If the ename parameter was an event name, this is the addListener options.

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners = myButton.mon({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

this

anim ( config )
private pri

Process the passed fx configuration.

Parameters

config :  Object

animate ( animObj ) : Object
chainable ch

Performs custom animation on this object.

This method is applicable to both the Ext.Component class and the Ext.draw.sprite.Sprite class. It performs animated transitions of certain properties of this object over a specified timeline.

Animating a Ext.Component

When animating a Component, the following properties may be specified in from, to, and keyframe objects:

  • x - The Component's page X position in pixels.

  • y - The Component's page Y position in pixels

  • left - The Component's left value in pixels.

  • top - The Component's top value in pixels.

  • width - The Component's width value in pixels.

  • height - The Component's height value in pixels.

The following property may be set on the animation config root:

  • dynamic - Specify as true to update the Component's layout (if it is a Container) at every frame of the animation. Use sparingly as laying out on every intermediate size change is an expensive operation.

For example, to animate a Window to a new size, ensuring that its internal layout and any shadow is correct:

myWindow = Ext.create('Ext.window.Window', {
    title: 'Test Component animation',
    width: 500,
    height: 300,
    layout: {
        type: 'hbox',
        align: 'stretch'
    },
    items: [{
        title: 'Left: 33%',
        margin: '5 0 5 5',
        flex: 1
    }, {
        title: 'Left: 66%',
        margin: '5 5 5 5',
        flex: 2
    }]
});
myWindow.show();
myWindow.header.el.on('click', function() {
    myWindow.animate({
        to: {
            width: (myWindow.getWidth() == 500) ? 700 : 500,
            height: (myWindow.getHeight() == 300) ? 400 : 300
        }
    });
});

For performance reasons, by default, the internal layout is only updated when the Window reaches its final "to" size. If dynamic updating of the Window's child Components is required, then configure the animation with dynamic: true and the two child items will maintain their proportions during the animation.

Parameters

animObj :  Object

Configuration for Ext.fx.Anim. Note that the to config is required.

Returns

:Object

this

applyBind ( binds, currentBindings ) : Object

private pri

Transforms a Session config to a proper instance.

Available since: 5.0.0

Parameters

session :  Object

Returns

:Ext.data.Session

beforeBlur ( e )
protected pro

Template method to do any pre-blur processing.

Parameters

e :  Ext.event.Event

The event object

beforeDestroy
deprecated dep template tpl protected pro

Invoked before the Component is destroyed. This method is deprecated, override onDestroy instead.

Deprecated since version 6.2.0
Please override onDestroy instead

beforeFocus ( e )
protected pro

Template method to do any pre-focus processing.

Parameters

e :  Ext.event.Event

The event object

beforeLayout
template tpl protected pro

Occurs before componentLayout is run. In previous releases, this method could return false to prevent its layout but that is not supported in Ext JS 4.1 or higher. This method is simply a notification of the impending layout to give the component a chance to adjust the DOM. Ideally, DOM reads should be avoided at this time to reduce expensive document reflows.

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

beforeRender
template tpl protected pro

Allows additional behavior before rendering.

Note: If the Component has a ViewController and the controller has a beforeRender method it will be called passing the Component as the single param.

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

beforeSetPosition ( x, y, animate )
private pri

Template method called before a Component is positioned.

Ensures that the position is adjusted so that the Component is constrained if so configured.

Parameters

x :  Object

y :  Object

animate :  Object

beforeShow
template tpl protected pro

Invoked before the Component is shown.

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

bubble ( fn, [scope], [args] ) : Ext.Component
chainable ch

Bubbles up the component/container hierarchy, calling the specified function with each component. The scope (this) of function call will be the scope provided or the current component. The arguments to the function will be the args provided or the current component. If the function returns false at any point, the bubble is stopped.

Parameters

fn :  Function

The function to call

scope :  Object (optional)

The scope of the function. Defaults to current node.

args :  Array (optional)

The args to call the function with. Defaults to passing the current component.

Returns

:Ext.Component

this

cacheRefEls ( el )
private pri

Ensures that all elements with "data-ref" attributes get loaded into the cache. This really helps on IE8 where getElementById is a search not a lookup. By populating our cache with one search of the DOM we then have random access to the elements as we do our childEls wire up.

Parameters

el :  Object

calculateAnchorXY ( [anchor], [extraX], [extraY], [size] ) : Number[]
private pri

Calculates x,y coordinates specified by the anchor position on the element, adding extraX and extraY values.

Parameters

anchor :  String (optional)

The specified anchor position. See alignTo for details on supported anchor positions.

Defaults to: 'tl'

extraX :  Number (optional)

value to be added to the x coordinate

extraY :  Number (optional)

value to be added to the y coordinate

size :  Object (optional)

An object containing the size to use for calculating anchor position {width: (target width), height: (target height)} (defaults to the element's current size)

Returns

:Number[]

[x, y] An array containing the element's x and y coordinates

calculateConstrainedPosition ( [constrainTo], [proposedPosition], [local], [proposedSize] ) : Number[]
private pri

Calculates the new [x,y] position to move this Positionable into a constrain region.

By default, this Positionable is constrained to be within the container it was added to, or the element it was rendered to.

Priority is given to constraining the top and left within the constraint.

An alternative constraint may be passed.

Parameters

constrainTo :  String/HTMLElement/Ext.dom.Element/Ext.util.Region (optional)

The Element or Ext.util.Region into which this Component is to be constrained. Defaults to the element into which this Positionable was rendered, or this Component's Ext.Component#constrainTo.

proposedPosition :  Number[] (optional)

A proposed [X, Y] position to test for validity and to coerce into constraints instead of using this Positionable's current position.

local :  Boolean (optional)

The proposedPosition is local (relative to floatParent if a floating Component)

proposedSize :  Number[] (optional)

A proposed [width, height] size to use when calculating constraints instead of using this Positionable's current size.

Returns

:Number[]

If the element needs to be translated, the new [X, Y] position within constraints if possible, giving priority to keeping the top and left edge in the constrain region. Otherwise, false.

callOverridden ( args ) : Object
deprecated dep protected pro

Call the original method that was previously overridden with Ext.Base#override

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callOverridden();

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callOverridden(arguments)

Returns

:Object

Returns the result of calling the overridden method

Deprecated since version 4.1.0
Use method-callParent instead.

callParent ( args ) : Object
protected pro

Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext#define).

 Ext.define('My.Base', {
     constructor: function(x) {
         this.x = x;
     },

     statics: {
         method: function(x) {
             return x;
         }
     }
 });

 Ext.define('My.Derived', {
     extend: 'My.Base',

     constructor: function() {
         this.callParent([21]);
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // alerts 21

This can be used with an override as follows:

 Ext.define('My.DerivedOverride', {
     override: 'My.Derived',

     constructor: function(x) {
         this.callParent([x*2]); // calls original My.Derived constructor
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // now alerts 42

This also works with static and private methods.

 Ext.define('My.Derived2', {
     extend: 'My.Base',

     // privates: {
     statics: {
         method: function(x) {
             return this.callParent([x*2]); // calls My.Base.method
         }
     }
 });

 alert(My.Base.method(10));     // alerts 10
 alert(My.Derived2.method(10)); // alerts 20

Lastly, it also works with overridden static methods.

 Ext.define('My.Derived2Override', {
     override: 'My.Derived2',

     // privates: {
     statics: {
         method: function(x) {
             return this.callParent([x*2]); // calls My.Derived2.method
         }
     }
 });

 alert(My.Derived2.method(10); // now alerts 40

To override a method and replace it and also call the superclass method, use method-callSuper. This is often done to patch a method to fix a bug.

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

Returns

:Object

Returns the result of calling the parent method

callSuper ( args ) : Object
protected pro

This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.

Consider:

 Ext.define('Ext.some.Class', {
     method: function() {
         console.log('Good');
     }
 });

 Ext.define('Ext.some.DerivedClass', {
     extend: 'Ext.some.Class',

     method: function() {
         console.log('Bad');

         // ... logic but with a bug ...

         this.callParent();
     }
 });

To patch the bug in Ext.some.DerivedClass.method, the typical solution is to create an override:

 Ext.define('App.patches.DerivedClass', {
     override: 'Ext.some.DerivedClass',

     method: function() {
         console.log('Fixed');

         // ... logic but with bug fixed ...

         this.callSuper();
     }
 });

The patch method cannot use method-callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callSuper(arguments)

Returns

:Object

Returns the result of calling the superclass method

cancelFocus
protected pro

Cancel any deferred focus on this component

cascade ( fn, [scope], [origArgs] ) : Ext.container.Container
chainable ch

this

clipTo ( clippingEl, sides )
private pri

Clips this Component/Element to fit within the passed element's or component's view area

Parameters

clippingEl :  Ext.Component/Ext.dom.Element/Ext.util.Region

The Component or element or Region which should clip this element even if this element is outside the bounds of that region.

sides :  Number

The sides to clip 1=top, 2=right, 4=bottom, 8=left.

This is to support components being clipped to their logical owner, such as a grid row editor when the row being edited scrolls out of sight. The editor should be clipped at the edge of the scrolling element.

clipToScroller ( scroller )
private pri

Clips this floating element to the scrolling element in line with how its topmost anchoring element is clipped.

Parameters

scroller :  Object

cloneConfig ( overrides ) : Ext.Component

Clone the current component using the original config values passed into this instance by default.

Parameters

overrides :  Object

A new config containing any properties to override in the cloned version. An id property can be passed on this object, otherwise one will be generated to avoid duplicates.

Returns

:Ext.Component

clone The cloned copy of this component

constrainBox ( box )
private pri

Parameters

box :  Object

constructPlugin ( plugin )
private pri

Parameters

plugin :  String/Object

string or config object containing a ptype property.

Constructs a plugin according to the passed config object/ptype string.

Ensures that the constructed plugin always has a cmp reference back to this component. The setting up of this is done in PluginManager. The PluginManager ensures that a reference to this component is passed to the constructor. It also ensures that the plugin's setCmp method (if any) is called.

constructPlugins
private pri

Returns an array of fully constructed plugin instances. This converts any configs into their appropriate instances.

It does not mutate the plugins array. It creates a new array.

constructor ( config )

Creates a new Toolbar

Parameters

config :  Object/Object[]

A config object or an array of buttons to method-add eslint-enable max-len

contains ( comp, [deep] ) : Boolean

Determines whether the passed Component is either an immediate child of this Container, or whether it is a descendant.

Parameters

comp :  Ext.Component

The Component to test.

deep :  Boolean (optional)

Pass true to test for the Component being a descendant at any level.

Defaults to: false

Returns

:Boolean

true if the passed Component is contained at the specified level.

convertPositionSpec ( posSpec )
private pri

This function converts a legacy alignment string such as 't-b' into a pair of edge, offset objects which describe the alignment points of the two regions.

So tl-br becomes {myEdge:'t', offset:0}, {otherEdge:'b', offset:100}

This not only allows more flexibility in the alignment possibilities, but it also resolves any ambiguity as to chich two edges are desired to be adjacent if an anchor pointer is required.

Parameters

posSpec :  Object

createRelayer ( newName, [beginEnd] ) : Function
private pri

Creates an event handling function which re-fires the event from this object as the passed event name.

Parameters

newName :  String

The name under which to re-fire the passed parameters.

beginEnd :  Array (optional)

The caller can specify on which indices to slice.

Returns

:Function

destroy

Destroys the Component. This method must not be overridden because Component destruction sequence is conditional; if a beforedestroy handler returns false we must abort destruction.

To add extra functionality to destruction time in a subclass, override the doDestroy method.

Available since: 1.1.0

destroyMembers ( args )

Destroys member properties by name.

If a property name is the name of a config, the getter is not invoked, so if the config has not been initialized, nothing will be done.

The property will be destroyed, and the corrected name (if the property is a config and config names are prefixed) will set to null in this object's dictionary.

Parameters

args :  String...

One or more names of the properties to destroy and remove from the object.

disable ( silent ) :
chainable ch

Disables all child input fields and buttons.

Parameters

silent :  Object

Returns

:

doApplyRenderTpl ( out, values )
private pri

Called from the selected frame generation template to insert this Component's inner structure inside the framing structure.

When framing is used, a selected frame generation template is used as the primary template of the #getElConfig instead of the configured renderTpl. The renderTpl is invoked by this method which is injected into the framing template.

Parameters

out :  Object

values :  Object

doAutoRender
private pri

Handles autoRender. Floating Components may have an ownerCt. If they are asking to be constrained, constrain them within that ownerCt, and have their z-index managed locally. Floating Components are always rendered to document.body

doComponentLayout Ext.Component
chainable ch deprecated dep

This method needs to be called whenever you change something on this component that equires the Component's layout to be recalculated.

Returns

:Ext.Component

this

Deprecated since version 4.1
Use Ext.Component#method-updateLayout instead.

doConstrain ( [constrainTo] )

Moves this floating Component into a constrain region.

By default, this Component is constrained to be within the container it was added to, or the element it was rendered to.

An alternative constraint may be passed.

Parameters

constrainTo :  String/HTMLElement/Ext.dom.Element/Ext.util.Region (optional)

The Element or Ext.util.Region into which this Component is to be constrained. Defaults to the element into which this floating Component was rendered.

doDestroy
private pri

Perform the actual destruction sequence.

As a rule of thumb, subclasses should destroy their child Components and/or other objects before calling parent method. Any object references will be nulled after this method has finished, to prevent the possibility of memory leaks.

Available since: 6.2.0

doFireDelegatedEvent ( eventName, args )
private pri

Fires a delegated event. Users should not invoke this method directly. It is called automatically by the framework as needed (see the "delegate" event option of addListener for more details.

Parameters

eventName :  Object

args :  Object

doFireEvent ( eventName, args, bubbles )
private pri

Continue to fire event.

Parameters

eventName :  String

args :  Array

bubbles :  Boolean

doRemove ( component, flags )
private pri

Parameters

component :  Object

flags :  Object

down ( [selector] ) : Ext.Component

Retrieves the first descendant of this container which matches the passed selector. The passed in selector must comply with an Ext.ComponentQuery selector, or it can be an actual Ext.Component.

Parameters

selector :  String/Ext.Component (optional)

An Ext.ComponentQuery selector or Ext.Component. If no selector is specified, the first child will be returned.

Returns

:Ext.Component

The matching descendant Ext.Component (or null if no match was found).

enable ( silent ) :
chainable ch

Enables all child input fields and buttons.

Parameters

silent :  Object

Returns

:

enableBubble ( eventNames )

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. There is no implementation in the Observable base class.

This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component#getBubbleTarget. The default implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to access the required target more quickly.

Example:

Ext.define('Ext.overrides.form.field.Base', {
    override: 'Ext.form.field.Base',

    //  Add functionality to Field's initComponent to enable
    // the change event to bubble
    initComponent: function () {
        this.callParent();
        this.enableBubble('change');
    }
});

var myForm = Ext.create('Ext.form.Panel', {
    title: 'User Details',
    items: [{
        ...
    }],
    listeners: {
        change: function() {
            // Title goes red if form has been modified.
            myForm.header.setStyle('color', 'red');
        }
    }
});

Parameters

eventNames :  String/String[]

The event name to bubble, or an Array of event names.

ensureAttachedToBody ( [runLayout] )

Ensures that this component is attached to document.body. If the component was rendered to Ext#getDetachedBody, then it will be appended to document.body. Any configured position is also restored.

Parameters

runLayout :  Boolean (optional)

True to run the component's layout.

Defaults to: false

findFocusTarget Ext.Component
private pri

Finds an alternate Component to focus if this Component is disabled while focused, or focused while disabled, or otherwise unable to focus.

In both cases, focus must not be lost to document.body, but must move to an intuitively connectible Component, either a sibling, or uncle or nephew.

This is both for the convenience of keyboard users, and also for when focus is tracked within a Component tree such as for ComboBoxes and their dropdowns.

For example, a ComboBox with a PagingToolbar in is BoundList. If the "Next Page" button is hit, the LoadMask shows and focuses, the next page is the last page, so the "Next Page" button is disabled. When the LoadMask hides, it attempt to focus the last focused Component which is the disabled "Next Page" button. In this situation, focus should move to a sibling within the PagingToolbar.

Returns

:Ext.Component

A closely related focusable Component to which focus can move.

findParentBy ( fn ) : Ext.container.Container

Find a container above this component at any level by a custom function. If the passed function returns true, the container will be returned.

See also the up method.

Parameters

Returns

:Ext.container.Container

The first Container for which the custom function returns true

findParentByType ( xtype ) : Ext.container.Container

Find a container above this component at any level by xtype or class

See also the up method.

Parameters

xtype :  String/Ext.Class

The xtype string for a component, or the class of the component directly

Returns

:Ext.container.Container

The first Container which matches the given xtype or class

findPlugin ( ptype ) : Ext.plugin.Abstract

Retrieves plugin from this component's collection by its ptype.

var grid = Ext.create('Ext.grid.Panel', {
    store: {
        fields: ['name'],
        data: [{
            name: 'Scott Pilgrim'
        }]
    },
    columns: [{
        header: 'Name',
        dataIndex: 'name',
        editor: 'textfield',
        flex: 1
    }],
    selType: 'cellmodel',
    plugins: [{
        ptype: 'cellediting',
        clicksToEdit: 1,
        id: 'myplugin'
    }],
    height: 200,
    width: 400,
    renderTo: Ext.getBody()
});

grid.findPlugin('cellediting');  // the cellediting plugin

finishRender ( containerIdx )
private pri

This method visits the rendered component tree in a "top-down" order. That is, this code runs on a parent component before running on a child. This method calls the onRender method of each component.

Parameters

containerIdx :  Number

The index into the Container items of this Component.

fireAction ( eventName, args, fn, [scope], [options], [order] )
deprecated dep

Fires the specified event with the passed parameters and executes a function (action). By default, the action function will be executed after any "before" event handlers (as specified using the order option of addListener), but before any other handlers are fired. This gives the "before" handlers an opportunity to cancel the event by returning false, and prevent the action function from being called.

The action can also be configured to run after normal handlers, but before any "after" handlers (as specified using the order event option) by passing 'after' as the order parameter. This configuration gives any event handlers except for "after" handlers the opportunity to cancel the event and prevent the action function from being called.

Parameters

eventName :  String

The name of the event to fire.

args :  Array

Arguments to pass to handlers and to the action function.

fn :  Function

The action function.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

Event options for the action function. Accepts any of the options of addListener

order :  String (optional)

The order to call the action function relative too the event handlers ('before' or 'after'). Note that this option is simply used to sort the action function relative to the event handlers by "priority". An order of 'before' is equivalent to a priority of 99.5, while an order of 'after' is equivalent to a priority of -99.5. See the priority option of addListener for more details.

Defaults to: 'before'

Deprecated since version 5.5
Use fireEventedAction instead.

fireEvent ( eventName, args ) : Boolean

Fires the specified event with the passed parameters (minus the event name, plus the options object passed to addListener).

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

Parameters

eventName :  String

The name of the event to fire.

args :  Object...

Variable number of parameters are passed to handlers.

Returns

:Boolean

returns false if any of the handlers return false otherwise it returns true.

fireEventArgs ( eventName, args ) : Boolean

Fires the specified event with the passed parameter list.

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

Parameters

eventName :  String

The name of the event to fire.

args :  Object[]

An array of parameters which are passed to handlers.

Returns

:Boolean

returns false if any of the handlers return false otherwise it returns true.

fireEventedAction ( eventName, args, fn, [scope], [fnArgs] ) : Boolean

Fires the specified event with the passed parameters and executes a function (action). Evented Actions will automatically dispatch a 'before' event passing. This event will be given a special controller that allows for pausing/resuming of the event flow.

By pausing the controller the updater and events will not run until resumed. Pausing, however, will not stop the processing of any other before events.

Parameters

eventName :  String

The name of the event to fire.

args :  Array

Arguments to pass to handlers and to the action function.

fn :  Function/String

The action function.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

fnArgs :  Array/Boolean (optional)

Optional arguments for the action fn. If not given, the normal args will be used to call fn. If false is passed, the args are used but if the first argument is this instance it will be removed from the args passed to the action function.

Returns

:Boolean

fireHierarchyEvent ( eventName )
private pri

This method fires an event on Ext.GlobalEvents allowing interested parties to know of certain critical events for this component. This is done globally because the (few) listeners can immediately receive the event rather than bubbling the event only to reach the top and have no listeners.

The main usage for these events is to do with floating components. For example, the load mask is a floating component. The component it is masking may be inside several containers. As such, they need to know when component is hidden, either directly, or via a parent container being hidden. To do this they subscribe to these events and filter out the appropriate container.

This functionality is contained in Component (as opposed to Container) because a Component can be the ownerCt for a floating component (loadmask), and the loadmask needs to know when its owner is shown/hidden so that its hidden state can be synchronized.

Available since: 4.2.0

Parameters

eventName :  String

The event name.

fitContainer ( animate )
private pri

Parameters

animate :  Object

focus ( [selectText], [delay], [callback], [scope] ) : Ext.Component

If applicable, true to also select all the text in this component, or an array consisting of start and end (defaults to start) position of selection.

delay :  Boolean/Number (optional)

Delay the focus this number of milliseconds (true for 10 milliseconds).

callback :  Function (optional)

Only needed if the delay parameter is used. A function to call upon focus.

scope :  Function (optional)

Only needed if the delay parameter is used. The scope (this reference) in which to execute the callback.

Returns

:Ext.Component

The focused Component. Usually this Component. Some Containers may delegate focus to a descendant Component (Ext.window.Windows can do this through their defaultFocus config option. If this component is disabled, a closely related component will be focused and that will be returned.

forceComponentLayout ( [options] )
deprecated dep

Updates this component's layout. If this update affects this components ownerCt, that component's updateLayout method will be called to perform the layout instead. Otherwise, just this component (and its child items) will layout.

Returns

:Ext.dom.Element

the focus holding element.

getFrameInfo Boolean
private pri

On render, reads an encoded style attribute, "filter" from the style of this Component's element. This information is memoized based upon the CSS class name of this Component's element. Because child Components are rendered as textual HTML as part of the topmost Container, a dummy div is inserted into the document to receive the document element's CSS class name, and therefore style attributes.

Returns

:Boolean

getFrameTpl ( table )
private pri

Parameters

table :  Object

getInherited ( [inner] ) : Object

This method returns an object containing the inherited properties for this instance.

Available since: 5.0.0

Parameters

inner :  Boolean (optional)

Pass true to return inheritedStateInner instead of the normal inheritedState object. This is only needed internally and should not be passed by user code.

Defaults to: false

Returns

:Object

The inheritedState object containing inherited properties.

getInheritedConfig ( property, [skipThis] ) : Mixed

This method returns the value of a config property that may be inherited from some ancestor.

In some cases, a config may be explicitly set on a component with the intent of only being presented to its children while that component should act upon the inherited value (see referenceHolder for example). In these cases the skipThis parameter should be specified as true.

Available since: 5.0.0

Parameters

property :  String

The name of the config property to return.

skipThis :  Boolean (optional)

Pass true if the property should be ignored if found on this instance. In other words, true means the property must be inherited and not explicitly set on this instance.

Defaults to: false

Returns

:Mixed

The value of the requested property.

getInitialConfig ( [name] ) : Object/Mixed

Returns the initial configuration passed to the constructor when instantiating this class.

Given this example Ext.button.Button definition and instance:

Ext.define('MyApp.view.Button', {
    extend: 'Ext.button.Button',
    xtype: 'mybutton',

    scale: 'large',
    enableToggle: true
});

var btn = Ext.create({
    xtype: 'mybutton',
    renderTo: Ext.getBody(),
    text: 'Test Button'
});

Calling btn.getInitialConfig() would return an object including the config options passed to the create method:

xtype: 'mybutton',
renderTo: // The document body itself
text: 'Test Button'

Calling btn.getInitialConfig('text')returns 'Test Button'.

Parameters

name :  String (optional)

Name of the config option to return.

Returns

:Object/Mixed

The full config object or a single config value when name parameter specified.

getInsertPosition ( position ) : HTMLElement

This function takes the position argument passed to onRender and returns a DOM element that you can use in the insertBefore.

Index, element id or element you want to put this component before.

Returns

:HTMLElement

DOM element that you can use in the insertBefore

getLocalX Number

Returns

:Number

The local x coordinate

getLocalXY Number[]

Returns the x and y coordinates of this element relative to its offsetParent.

Returns

:Number[]

The local XY position of the element

getLocalY Number

Returns the y coordinate of this element reletive to its offsetParent.

Returns

:Number

The local y coordinate

getMaskTarget
protected pro

Returns the element which is masked by the mask method, or into which the LoadMask is rendered into.

The default implementation uses the maskElement configuration to access the Component's child element by name. By default, maskElement is null which means that null is returned from this method indicating that the mask needs to be rendered into the document because component structure should not be contaminated by mask elements.

Some subclasses may override this method if they have knowledge about external structures where a mask could usefully be rendered.

For example a Ext.view.Table will request that its owning Ext.panel.Table be masked. The GridPanel will have its own implementation of getMaskTarget which will return the element dictated by its own maskElement Panels use "el" as their maskElement by default, but that could be overridden to be "body" to leave toolbars and the header mouse-accessible.

getNamedItems Object

Returns an object holding the descendants of this container keyed by their name. This object should not be held past the scope of the function calling this method. It will not be valid if items are added or removed from this or any sub-container.

The intended usage is shown here (assume there are 3 components with names of "foo", "bar" and "baz" at some level below this container):

 onClick: function () {
     var items = this.getNamedItems();

     // using "items" we can access any descendant by its "name"

     items.foo.getValue() + items.bar.getValue() + items.baz.getValue();
 }

If this component has a name assigned to it, it is not included in this object. That name is understood to belong to the ancestor container configured as the nameHolder.

Available since: 6.5.0

Returns

:Object

An object with each named child. This will be null if this container has no descendants with a name specified.

getOffsetsTo ( offsetsTo ) : Number[]

Returns the offsets of this element from the passed element. The element must both be part of the DOM tree and not have display:none to have page coordinates.

Parameters

offsetsTo :  Ext.util.Positionable/HTMLElement/String

The Positionable, HTMLElement, or element id to get get the offsets from.

Returns

:Number[]

The XY page offsets (e.g. [100, -200])

getOverflowEl
private pri

    store: {
        fields: ['name'],
        data: [{
            name: 'Scott Pilgrim'
        }]
    },
    columns: [{
        header: 'Name',
        dataIndex: 'name',
        editor: 'textfield',
        flex: 1
    }],
    selType: 'cellmodel',
    plugins: [{
        ptype: 'cellediting',
        clicksToEdit: 1,
        id: 'myplugin'
    }],
    height: 200,
    width: 400,
    renderTo: Ext.getBody()
});

grid.getPlugin('myplugin');  // the cellediting plugin

Note: See also findPlugin. Prior to 6.2.0 the plugin had to have a pluginId property but this can now be just id. Both are supported (so plugins with a matching pluginId are still found) but id is preferred.

Parameters

id :  String

The id set on the plugin config object.

Returns

:Ext.plugin.Abstract

plugin instance or null if not found

getPosition ( [local] ) : Number[]

Gets the current XY position of the component's underlying element.

Parameters

local :  Boolean (optional)

If true the element's left and top are returned instead of page XY.

Defaults to: false

Returns

:Number[]

The XY position of the element (e.g., [100, 200])

getRefItems ( deep )
protected pro

Used by Ext.ComponentQuery, child and down to retrieve all of the items which can potentially be considered a child of this Container.

This may be overriden by Components which have ownership of Components that are not contained in the property-items collection.

NOTE: IMPORTANT note for maintainers: Items are returned in tree traversal order. Each item is appended to the result array followed by the results of that child's getRefItems call. Floating child items are appended after internal child items.

Parameters

deep :  Object

getRefOwner
protected pro

Used by Ext.ComponentQuery, and the up method to find the owning Component in the linkage hierarchy.

By default this returns the Container which contains this Component.

This may be overridden by Component authors who implement ownership hierarchies which are not based upon ownerCt, such as BoundLists being owned by Fields or Menus being owned by Buttons.

getReferences Object

Returns an object holding the descendants of this view keyed by their reference. This object should not be held past the scope of the function calling this method. It will not be valid if items are added or removed from this or any sub-container.

The intended usage is shown here (assume there are 3 components with reference values of "foo", "bar" and "baz" at some level below this container):

 onClick: function () {
     var refs = this.getReferences();

     // using "refs" we can access any descendant by its "reference"

     refs.foo.getValue() + refs.bar.getValue() + refs.baz.getValue();
 }

If this component has a reference assigned to it, that is not included in this object. That reference is understood to belong to the ancestor container configured as the referenceHolder.

Available since: 5.0.0

Returns

:Object

An object with each child reference. This will be null if this container has no descendants with a reference specified.

getScrollX Number

Returns the "x" scroll position for this component. Only applicable for scrollable components

Note that Component state will only be saved if the Component has a stateId and there as a StateProvider configured for the document.

Returns

:Object

getStyleProxy ( cls )
private pri

initBindable
private pri

This method triggers the lazy configs and must be called when it is time to fully boot up. The configs that must be initialized are: bind, publishes, session, twoWayBindable and viewModel.

Available since: 5.0.0

initComponent
template tpl protected pro

The initComponent template method is an important initialization step for a Component. It is intended to be implemented by each subclass of Ext.Component to provide any needed constructor logic. The initComponent method of the class being created is called first, with each initComponent method up the hierarchy to Ext.Component being called thereafter. This makes it easy to implement and, if needed, override the constructor logic of the Component at any step in the hierarchy.

The initComponent method must contain a call to callParent in order to ensure that the parent class' initComponent method is also called.

All config options passed to the constructor are applied to this before initComponent is called, so you can simply access them with this.someOption.

The following example demonstrates using a dynamic string for the text of a button at the time of instantiation of the class.

Ext.define('DynamicButtonText', {
    extend: 'Ext.button.Button',

    initComponent: function() {
        this.text = new Date();
        this.renderTo = Ext.getBody();
        this.callParent();
    }
});

Ext.onReady(function() {
    Ext.create('DynamicButtonText');
});

Available since: 1.1.0

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

initConfig ( instanceConfig ) : Ext.Base
chainable ch protected pro

Ext.define('My.awesome.Class', {
    // The default config
    config: {
        name: 'Awesome',
        isAwesome: true
    },

    constructor: function(config) {
        this.initConfig(config);
    }
});

var awesome = new My.awesome.Class({
    name: 'Super Awesome'
});

alert(awesome.getName()); // 'Super Awesome'

initEvents
protected pro

Initialize any events on this component

initFocusableElement ( force )
private pri

Sets up the focus listener on this Component's focusEl if it has one.

Form Components which must implicitly participate in tabbing order usually have a naturally focusable element as their focusEl, and it is the DOM event of that receiving focus which drives the Component's onFocus handling, and the DOM event of it being blurred which drives the onBlur handling.

Parameters

force :  Object

Parameters

ownerCandidate :  Ext.Component

The potential owner.

Returns

:Boolean

true if this component is a layout child of comp.

isLayoutRoot Boolean
protected pro

Determines whether this Component is the root of a layout. This returns true if this component can run its layout without assistance from or impact on its owner. If this component cannot run its layout given these restrictions, false is returned and its owner will be considered as the next candidate for the layout root.

Setting the _isLayoutRoot property to true causes this method to always return true. This may be useful when updating a layout of a Container which shrink wraps content, and you know that it will not change size, and so can safely be the topmost participant in the layout run.

Defaults to: false

Returns

:Boolean

true if this component is visible, false otherwise.

isXType ( xtype, [shallow] ) : Boolean

Tests whether or not this Component is of a specific xtype. This can test whether this Component is descended from the xtype (default) or whether it is directly of the xtype specified (shallow = true).

If using your own subclasses, be aware that a Component must register its own xtype to participate in determination of inherited xtypes.

For a list of all available xtypes, see the Ext.Component header.

Example usage:

Available since: 2.3.0

Parameters

xtype :  String

private pri

Gets the Form or Component that is used as the name holder for this component.

Available since: 6.5.0

Parameters

skipThis :  Boolean (optional)

false to return this as the name holder if this instance has set nameHolder. Unlike getInheritedConfig this method defaults to true because it is possible that a name property set by the owner of a component that is also a nameHolder itself. In this case, the name connects not to this component but to the parent nameHolder.

Defaults to: true

Returns

:Ext.Component

The name holder.

lookupReference ( ref ) : Ext.Component

Gets a reference to the component with the specified reference value.

The lookup method is a short-hand version of this method.

Available since: 5.0.0

Parameters

skipThis :  Boolean (optional)

false to return this as the reference holder if this instance has set referenceHolder. Unlike getInheritedConfig this method defaults to true because it is possible that a reference property set by the owner of a component that is also a referenceHolder itself. In this case, the reference connects not to this component but to the parent referenceHolder.

Defaults to: true

Returns

:Ext.app.ViewController/Ext.container.Container

The reference holder.

lookupSession ( [skipThis] ) : Ext.data.Session

Returns the Ext.data.Session for this instance. This property may come from this instance's session or be inherited from this object's parent.

Available since: 5.0.0

Parameters

skipThis :  Boolean (optional)

Pass true to ignore a session configured on this instance and only consider an inherited session.

Defaults to: false

Available since: 5.0.0

Parameters

skipThis :  Boolean (optional)

Pass true to ignore a viewModel configured on this instance and only consider an inherited view model.

Defaults to: false

Returns

:Ext.app.ViewModel

mask ( [msg], [msgCls] )

A message to show in the center of the mask layer.

msgCls :  String (optional)

A CSS class name to use on the message element in the center of the layer.

mon ( item, ename, [fn], [scope], [options] ) : Object

Shorthand for addManagedListener. The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.

Example:

Ext.define('Foo', {
    extend: 'Ext.Component',

    initComponent: function () {
        this.addManagedListener(MyApp.SomeSharedMenu, 'show', this.doSomething);
        this.callParent();
    }
});

As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.

As of version 5.1 it is no longer necessary to use this method in most cases because listeners are automatically managed if the scope object provided to addListener is an Observable instance. However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item to which to add a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function/String (optional)

If the ename parameter was an event name, this is the handler function or the name of a method on the specified scope.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

options :  Object (optional)

If the ename parameter was an event name, this is the addListener options.

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners = myButton.mon({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

move ( fromIdx, toIdx ) : Ext.Component
deprecated dep

Moves a Component within the Container. This method does not account for things like splitter components added by a layout. To better handle these situations, it is recommended to use moveBefore or moveAfter instead.

Parameters

fromIdx :  Number/Ext.Component

The index/component to move.

toIdx :  Number

The new index for the Component.

Returns

:Ext.Component

component The Component that was moved.

Deprecated since version 5.0
Use moveBefore or moveAfter instead.

moveAfter ( item, after ) : Ext.Component/Ext.Component[]

Moves the given item(s) into this container following after. This method will account for layout-generated components like splitters and should be used instead of index based method-move. If after is null then the item will be the first item in this container.

var tb = Ext.create({
    xtype: 'toolbar',
    renderTo: Ext.getBody(),
    items: [{
        text: 'one'
    }, {
        text: 'two'
    }]
});

// moves the 'one' button after the 'two' button
tb.moveAfter(tb.getComponent(0), tb.getComponent(1));

Available since: 5.0.0

Parameters

item :  Ext.Component/Ext.Component[]

The item to move. May be a component, component configuration object, or an array of either.

after :  Ext.Component

The reference component. May be null.

Returns

:Ext.Component/Ext.Component[]

The moved item(s).

moveBefore ( item, before ) : Ext.Component/Ext.Component[]

Moves the given item(s) into this container in front of before. This method will account for layout-generated components like splitters and should be used instead of index based method-move. If before is null then the item will be the last item in this container.

var tb = Ext.create({
    xtype: 'toolbar',
    renderTo: Ext.getBody(),
    items: [{
        text: 'one'
    }, {
        text: 'two'
    }]
});

// moves the 'two' button before the 'one' button
tb.moveBefore(tb.getComponent(1), tb.getComponent(0));

Available since: 5.0.0

Parameters

item :  Ext.Component/Ext.Component[]

The item to move. May be a component, component configuration object, or an array of either.

before :  Ext.Component

The reference component. May be null.

Returns

:Ext.Component/Ext.Component[]

The moved item(s).

mun ( item, ename, [fn], [scope] )

Shorthand for removeManagedListener. Removes listeners that were added by the mon method.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item from which to remove a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function (optional)

If the ename parameter was an event name, this is the handler function.

scope :  Object (optional)

If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

nextChild ( child, [selector] ) : Ext.Component

A method to find a child component after the passed child parameter. If a selector is also provided, the first child component matching the selector will be returned.

Parameters

child :  Ext.Component

The child to use as a starting point to find the next child.

selector :  String (optional)

A Ext.ComponentQuery selector to find the next child. This will return the next child matching this selector. This parameter is optional.

Returns

:Ext.Component

The next child found, null if no child found.

nextNode ( [selector] ) : Ext.Component

Returns the next node in the Component tree in tree traversal order.

Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree to attempt to find a match. Contrast with nextSibling.

Parameters

selector :  String (optional)

A Ext.ComponentQuery selector to filter the following nodes.

Returns

:Ext.Component

The next node (or the next node which matches the selector). Returns null if there is no matching node.

nextSibling ( [selector] ) : Ext.Component

Returns the next sibling of this Component.

Optionally selects the next sibling which matches the passed Ext.ComponentQuery selector.

May also be referred to as next()

Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with nextNode

Parameters

selector :  String (optional)

A Ext.ComponentQuery selector to filter the following items.

Returns

:Ext.Component

The next sibling (or the next sibling which matches the selector). Returns null if there is no matching sibling.

on ( eventName, [fn], [scope], [options], [order] ) : Object

The on method is shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("itemclick", this.onItemClick, this);

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

myGridPanel.on({
    cellclick: this.onCellClick,
    select: this.onSelect,
    viewready: this.onViewReady,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellclick: {fn: this.onCellClick, scope: this, single: true},
    viewready: {fn: panel.onViewReady, scope: panel}
});

Names of methods in a specified scope may also be used:

myGridPanel.on({
    cellclick: {fn: 'onCellClick', scope: this, single: true},
    viewready: {fn: 'onViewReady', scope: panel}
});

Parameters

eventName :  String/Object

The name of the event to listen for. May also be an object who's property names are event names.

fn :  Function/String (optional)

The method the event invokes or the name of the method within the specified scope. Will be called with arguments given to Ext.util.Observable#fireEvent plus the options parameter described below.

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

options :  Object (optional)

An object containing handler configuration.

Note: The options object will also be passed as the last argument to every event handler.

This object may contain any of the following properties:

scope :  Object

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

delay :  Number

The number of milliseconds to delay the invocation of the handler after the event fires.

single :  Boolean

True to add a handler to handle just the next firing of the event, and then remove itself.

buffer :  Number

Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

onFrame :  Number

Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.

target :  Ext.util.Observable

Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

element :  String

This option is only valid for listeners bound to Ext.Component. The name of a Component property which references an Ext.dom.Element to add a listener to.

This option is useful during Component construction to add DOM event listeners to elements of Ext.Component which will exist only after the Component is rendered.

For example, to add a click listener to a Panel's body:

  var panel = new Ext.panel.Panel({
      title: 'The title',
      listeners: {
          click: this.handlePanelClick,
          element: 'body'
      }
  });

In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.

 panel.body.un(...)

delegate :  String (optional)

A simple selector to filter the event target or look for a descendant of the target.

The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

See the delegate example below.

capture :  Boolean (optional)

When set to true, the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase.

The capture option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

stopPropagation :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopPropagation on the event object before firing the handler.

preventDefault :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call preventDefault on the event object before firing the handler.

stopEvent :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopEvent on the event object before firing the handler.

args :  Array (optional)

Optional set of arguments to pass to the handler function before the actual fired event arguments. For example, if args is set to ['foo', 42], the event handler function will be called with an arguments list like this:

 handler('foo', 42, <actual event arguments>...);

destroyable :  Boolean (optional)

When specified as true, the function returns a destroyable object. An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un; particularly when removing multiple listeners. NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config.

Defaults to:

false

priority :  Number (optional)

An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.

order :  String (optional)

A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:

  • 'before': equal to a priority of 100
  • 'current': equal to a priority of 0 or default priority
  • 'after': equal to a priority of -100

Defaults to:

'current'

order :  String (optional)

A shortcut for the order event option. Provided for backward compatibility. Please use the priority event option instead.

Defaults to: 'current'

Returns

:Object

Only when the destroyable option is specified.

A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

this.btnListeners =  = myButton.on({
    destroyable: true
    mouseover:   function() { console.log('mouseover'); },
    mouseout:    function() { console.log('mouseout'); },
    click:       function() { console.log('click'); }
});

And when those listeners need to be removed:

Ext.destroy(this.btnListeners);

or

this.btnListeners.destroy();

This method is called only by component authors.

Available since: 5.0.0

Parameters

property :  String (optional)

The name of the property to update.

value :  Object (optional)

The value of property. Only needed if property is given.

query ( [selector] ) : Ext.Component[]

Retrieves all descendant components which match the passed selector. Executes an Ext.ComponentQuery.query using this container as its root.

Parameters

selector :  String (optional)

Selector complying to an Ext.ComponentQuery selector. If no selector is specified all items will be returned.

Returns

:Ext.Component[]

Components which matched the selector

queryBy ( fn, [scope] ) : Ext.Component[]

registerFloatingItem ( cmp )

Called by Component#doAutoRender

Register a Container configured floating: true with this Component's Ext.ZIndexManager.

Parameters

cmp :  Object

relayEvents ( origin, events, [prefix] ) : Object

Relays selected events from the specified Observable as if the events were fired by this.

For example if you are extending Grid, you might decide to forward some events from store. So you can do this inside your initComponent:

this.relayEvents(this.getStore(), ['load']);

The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword (unless the event is handled by a controller's control/listen event listener in which case 'this' will be the controller rather than the grid).

Parameters

origin :  Object

The Observable whose events this object is to relay.

events :  String[]/Object

Array of event names to relay or an Object with key/value pairs translating to ActualEventName/NewEventName respectively. For example: this.relayEvents(this, {add:'push', remove:'pop'});

Would now redispatch the add event of this as a push event and the remove event as a pop event.

prefix :  String (optional)

A common prefix to prepend to the event names. For example:

this.relayEvents(this.getStore(), ['load', 'clear'], 'store');

Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.

Returns

:Object

A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:

this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');

Can be undone by calling

Ext.destroy(this.storeRelayers);

or this.store.relayers.destroy();

removeManagedListener ( item, ename, [fn], [scope] )

Removes listeners that were added by the mon method.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item from which to remove a listener/listeners.

ename :  Object/String

The event name, or an object containing event name properties.

fn :  Function (optional)

If the ename parameter was an event name, this is the handler function.

removeUIClsFromElement ( uiCls )
protected pro

Method which removes a specified UI + uiCls from the components element. The cls which is added to the element will be: this.baseCls + '-' + ui + uiCls.

Parameters

uiCls :  String

The UI class to remove from the element.

removeUIFromElement
private pri

Method which removes a specified UI from the components element.

render ( [container], [position] )

Renders the Component into the passed HTML element.

If you are using a Ext.container.Container object to house this Component, then do not use the render method.

A Container's child Components are rendered by that Container's layout manager when the Container is first rendered.

When creating complex UIs, it is important to remember that sizing and positioning of child items is the responsibility of the Container's layout manager. If you expect child items to be sized in response to user interactions, you must configure the Container with a layout manager which creates and manages the type of layout you have in mind.

Omitting the Container's layout config means that a basic layout manager is used which does nothing but render child components sequentially into the Container. No sizing or positioning will be performed in this situation.

Parameters

container :  Ext.dom.Element/HTMLElement/String (optional)

The element this Component should be rendered into. If it is being created from existing markup, this should be omitted.

position :  String/Number (optional)

The element ID or DOM node index within the container before which this component will be inserted (defaults to appending to the end of the container)

If a numeric value is passed, it will be used as the callback interval (in milliseconds), overriding the autoClear value. All other options will be defaulted as with the boolean option. To customize any other options, you can pass an object in the format:

wait :  Number

The number of milliseconds to wait before clearing (defaults to autoClear).

anim :  Boolean

False to clear the status immediately once the callback executes (defaults to true which fades the status out).

override ( members ) : Ext.Base
chainable ch static sta

Override members of this class. Overridden methods can be invoked via callParent.

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Direct use of this method should be rare. Use Ext.define instead:

Ext.define('My.CatOverride', {
    override: 'My.Cat',
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).
