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.

 });

To remove bindings:

 panel.setBind({
     title: null
 });

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

floated : Boolean
bindable bind

A Component may be floated above all other components in the application. This means that the component is absolutely positioned, and will move to the front and occlude other sibling floated component if clicked.

A Floated component may have floated descendants. It will bring these decendants to the front with it when brought to the front of its sibling floated components.

By default, descendant floated components are all positioned using the viewport coordinate system. To make a floating component a positioning parent for descendants, and have the ancestors positioned relatively, configure the parent floated component with cfg-relative: true.

Returns the value of hideAnimation

Returns

String / Mixed

setHideAnimation (hideAnimation)

Sets the value of hideAnimation

Returns the value of html

Returns

String / Ext.dom.Element / HTMLElement

setHtml (html)

Sets the value of html

Parameters

html :  String / Ext.dom.Element / HTMLElement

id : String

The unique id of this component instance.

It should not be necessary to use this configuration except for singleton objects in your application. Components created with an id may be accessed globally using Ext.getCmp.

Instead of using assigned ids, use the itemId config, and Ext.ComponentQuery which provides selector-based searching for Sencha Components analogous to DOM querying. The Ext.Container class contains 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.

Note: to avoid complications imposed by a unique id also see itemId.

Defaults to an auto-assigned id.

getId String

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

Returns

:String

id

inactiveLabel : String
bindable bind

The label to add to the toggle field when it is toggled off. Only available in the Blackberry theme.

Defaults to:

Sets the value of inactiveLabel

Parameters

inactiveLabel :  String

increment : Number
bindable bind

Defaults to:

1

getIncrement : Number

Returns the value of increment

Returns

Number

setIncrement (increment)

Sets the value of increment

Parameters

increment :  Number

inputCls : String
bindable bind

CSS class to add to the input element of this fields component

Returns

String

setInputCls (inputCls)

Sets the value of inputCls

Parameters

inputCls :  String

inputType : String
deprecated dep bindable bind

The type attribute for input fields -- e.g. radio, text, password, file. The types 'file' and 'password' must be used to render those field types currently -- there are no separate Ext components for those.

Defaults to:

'text'

Deprecated since version 2.0

getInputType : String

Returns the value of inputType

Returns

String

setInputType (inputType)

Sets the value of inputType

Parameters

inputType :  String

isFocused : Boolean
private pri

true if this field is currently focused.

itemId : String
bindable bind

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 Ext#getCmp, use itemId with Ext.Container#getComponent which will retrieve itemId's or id's. Since itemId's are an index to the container's internal MixedCollection, the itemId is scoped locally to the container - avoiding potential conflicts with Ext.ComponentManager which requires a unique id.

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

Defaults to:

undefined

getItemId : String

Returns the value of itemId

Returns

String

setItemId (itemId)

Sets the value of itemId

Parameters

itemId :  String

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

left : Number / String
bindable bind

The absolute left position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component become 'positioned', which means it will no longer participate in the layout of the Container that it resides in.

Defaults to:

null

getLeft : Number / String

Returns the value of left

Returns

Number / String

setLeft (left)

Sets the value of left

Parameters

left :  Number / String

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 DataView'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

liveUpdate : Boolean

true to fire change events while the slider is dragging. false will only fire a change once the drag is complete.

Defaults to:

false

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

An object or array of objects that will provide custom functionality for this component. If a string is provided or a string is one of the elements of the array, that string is treated as the type alias. For example, "listpaging" is the type alias for Ext.plugin.ListPaging. The full alias includes the "plugin." prefix (i.e., 'plugin.listpaging').

Plugins should derive from Ext.plugin.Abstract but this is not required. The only requirement for a valid plugin is that it contain an init() method that accepts a reference to the owning component.

When a component is created, if any plugins are available, the component will call the init method on each plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the component as needed to provide its functionality.

Example code

A plugin by alias:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: 'listpaging'
 });

Multiple plugins by alias:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['listpaging', 'pullrefresh']
 });

Single plugin by class name with config options:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: {
         type: 'listpaging',
         autoPaging: true
     }
 });

Multiple plugins by type and class name with config options:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: [{
         xclass: 'Ext.plugin.PullRefresh',
         pullRefreshText: 'Pull to refresh...'
     }, {
         type: 'listpaging',
         autoPaging: true
     }]
 });

Defaults to:

null

getPlugins : Object / String / Object[] / String[]

Returns the value of plugins

Returns

Object / String / Object[] / String[]

setPlugins (plugins)

Sets the value of plugins

Parameters

plugins :  Object / String / Object[] / String[]

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.

bindable bind

The tooltip for this component - can be a string to be used as innerHTML (html tags are accepted) or Ext.tip.ToolTip config object.

The default behavior is to use a shared tip instance. The tooltip configuration is registered with the Ext.tip.Manager. To enable this, your application can set the Ext.app.Application#quickTips config, or an instance of the Ext.tip.Manager may be created manually.

To force a unique tooltip instance to be created, specify autoCreate: true on this configuration.

Configuring this with autoHide: false implies autoCreate: true so that the desired persistent behavior can be obtained with other targets still showing the singleton instance.

Defaults to:

null

getTooltip : String / Object

Returns the value of tooltip

Returns

String / Object

setTooltip (tooltip)

Sets the value of tooltip

Parameters

tooltip :  String / Object

Sets the value of top

Parameters

top :  Number / String

touchAction : Object
bindable bind

Emulates the behavior of the CSS href="https://www.w3.org/TR/pointerevents/#the-touch-action-css-property" class="external-link" target="_blank">https://www.w3.org/TR/pointerevents/#the-touch-action-css-property 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 reference elements using the reference 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.Widget', {
    touchAction: {
        panX: false
    },
    listeners: {
        drag: function(e) {
            // implement drag logic
        }
    }
});

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

width : Number / String
bindable bind

The width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. By default, if this is not explicitly set, this Component's element will simply have its own natural size. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

getWidth : Number / String

Returns the value of width

Returns

Number / String

setWidth (width)

Sets the value of width

Parameters

width :  Number / String

x : Number
bindable bind

Only valid when a component is cfg-floated

The x position at which to position this component. This is usually viewport-relative. But if there is a relative: true ancestor, it will be relative to that.

Defaults to:

0

getX : Number

Returns the value of x

Returns

Number

setX (x)

Sets the value of x

Parameters

x :  Number

xtype : String

The xtype configuration option can be used to optimize Component creation and rendering. It serves as a shortcut to the full component name. For example, the component Ext.button.Button has an xtype of button.

You can define your own xtype on a custom Ext.Component by specifying the alias config option with a prefix of widget. For example:

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

Any Component can be created implicitly as an object config with an xtype specified, allowing it to be declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources until they are actually needed. In complex, nested layouts containing many Components, this can make a noticeable improvement in performance.

// Explicit creation of contained Components:
var panel = new Ext.Panel({
   // ...
   items: [
      Ext.create('Ext.button.Button', {
         text: 'OK'
      })
   ]
});

// Implicit creation using xtype:
var panel = new Ext.Panel({
   // ...
   items: [{
      xtype: 'button',
      text: 'OK'
   }]
});

In the first example, the button will always be created immediately during the panel's initialization. With many added Components, this approach could potentially slow the rendering of the page. In the second example, the button will not be created or rendered until the panel is actually displayed in the browser. If the panel is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and will never consume any resources whatsoever.

}

$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

activeAnimation
private pri

Defaults to:

null

classCls
protected pro

A CSS class to apply to the main element that will be inherited down the class hierarchy. Subclasses may override this property on their prototype to add their own CSS class in addition to the CSS classes inherited from ancestor classes via the prototype chain. For example

Ext.define('Foo', {
    extend: 'Ext.Widget',
    classCls: 'foo'
});

Ext.define('Bar', {
    extend: 'Foo',
    classCls: 'bar'
});

var bar = new Bar();

console.log(bar.element.className); // outputs 'foo bar'

Defaults to:

null

classClsRoot
protected pro

When set to true during widget class definition, that class will be the "root" for classCls inheritance. Derived classes may set this to true to avoid inheriting a classCls from their superclass.

Defaults to:

true

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

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'

destroyed : Boolean
protected pro

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

Defaults to:

false

dockPositions
readonly ro private pri

Defaults to:

{
    top: true,
    right: true,
    bottom: true,
    left: true
}

element : Object
protected pro

A configuration object for Ext.Element.create() that is used to create the Element template. Supports all the standard options of a Ext.Element.create() config and adds 2 additional options:

  1. reference - this option specifies a name for Element references. These references names become properties of the Widget instance and refer to Ext.Element instances that were created using the template:

    element: {

     reference: 'element',
     children: [{
         reference: 'innerElement'
     }]
    

    }

After construction of a widget the reference elements are accessible as follows:

var foo = new FooWidget(),
    innerEl = foo.innerElement; // an Ext.Element that wraps the innerElement

The reference attribute is optional, but all Widgets must have a 'element' reference on some element within the template (usually the outermost one).

  1. listeners - a standard listeners object as specified by Ext.mixin.Observable.

    element: {

     reference: 'element',
     listeners: {
         click: 'onClick'
     },
     children: [{
         reference: 'innerElement',
         listeners: {
             click: 'onInnerClick'
         }
     }]
    

    }

Since listeners cannot be attached without an Ext.Element reference the reference property MUST be specified in order to use listeners.

The Widget instance is used as the scope for all listeners specified in this way, so it is invalid to use the scope option in the listeners config since it will always be overwritten using this.

Defaults to:

{
    reference: 'element'
}

eventsSuspended
private pri

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

Defaults to:

0

floatedSelector : String
readonly ro private pri

The CSS selector to match floated elements.

Defaults to:

".x-floated"

floatingCls : String
readonly ro private pri

The CSS class to add to this component when it is floated at the viewport level.

Defaults to:

"x-floated"

floatWrapCls : String
readonly ro private pri

The CSS class to add to this component's floatWrap when it's created.

Defaults to:

"x-float-wrap"

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);
 }

isComponent
private pri

Defaults to:

true

isConfiguring : Boolean
readonly ro protected pro

This property is set to true during the call to initConfig.

Defaults to:

false

Available since: 5.0.0

isField : Boolean

Set to true on all Ext.field.Field subclasses. This is used by Ext.form.Panel#getValues to determine which components inside a form are fields.

Defaults to:

true

isFirstInstance : Boolean
readonly ro protected pro

This property is set to true if this instance is the first of its class.

Defaults to:

false

Available since: 5.0.0

isFormField
private pri

Defaults to:

true

isInner
private pri

Defaults to:

true

isInstance : Boolean
readonly ro protected pro

This value is true and is used to identify plain objects from instances of a defined class.

Defaults to:

true

isObservable : Boolean

true in this class to identify an object as an instantiated Observable, or subclass thereof.

Defaults to:

true

labelEl : Ext.dom.Element

The label Element associated with this Field.

Note: Only available if a label is specified.

noBorderCls : String
readonly ro private pri

The CSS class to add to this component should not have a border.

Defaults to:

Ext.baseCSSPrefix + 'noborder-trbl'

originalValue : Mixed

The original value of the field as configured in the value configuration. setting is true.

Defaults to:

this.getInitialConfig().value

positioned
private pri

Defaults to:

false

rendered
private pri

Defaults to:

false

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'
    },

    clone: function() {
        return new this.self();
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',
    statics: {
        speciesName: 'Snow Leopard'         // My.SnowLeopard.speciesName = 'Snow Leopard'
    }
});

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:

Defaults to: ""

addDelegatedListener ( eventName, fn, scope, options, order, caller, manager )
private pri

Adds a listeners with the "delegate" event option. Users should not invoke this method directly. Use the "delegate" event option of addListener instead.

Parameters

eventName :  Object

fn :  Object

scope :  Object

options :  Object

order :  Object

caller :  Object

manager :  Object

addDeprecations ( deprecations )
private pri

This method applies a versioned, deprecation declaration to this class. This is typically called by the deprecated config.

Parameters

deprecations :  Object

addElementReference ( name, domNode ) : Ext.dom.Element
private pri

Parameters

name :  String

The name of the reference

domNode :  HTMLElement

Returns

:Ext.dom.Element

addElementReferenceOnDemand ( name, domNode )
private pri

Reduces instantiation time for a Widget by lazily instantiating Ext.Element references the first time they are used. This optimization only works for elements with no listeners specified.

Parameters

name :  String

The name of the reference

domNode :  HTMLElement

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, ...);

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:

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:

order :  String (optional)

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

Combining Options

Using the options argument, it is possible to combine different types of listeners:

A delayed, one-time listener.

myPanel.on('hide', this.handleClick, this, {
    single: true,
    delay: 100
});

Attaching multiple handlers in 1 call

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers and handler configs.

grid.on({
    itemclick: 'onItemClick',
    itemcontextmenu: grid.onItemContextmenu,
    destroy: {
        fn: function () {
            // function called within the 'altCmp' scope instead of grid
        },
        scope: altCmp // unique scope for the destroy handler
    },
    scope: grid       // default scope - provided for example clarity
});

Delegate

This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example:

var panel = Ext.create({
    xtype: 'panel',
    renderTo: document.body,
    title: 'Delegate Handler Example',
    frame: true,
    height: 220,
    width: 220,
    html: '<h1 class="myTitle">BODY TITLE</h1>Body content'
});

// The click handler will only be called when the click occurs on the
// delegate: h1.myTitle ("h1" tag with class "myTitle")
panel.on({
    click: function (e) {
        console.log(e.getTarget().innerHTML);
    },
    element: 'body',
    delegate: 'h1.myTitle'
 });

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.SomeGlobalSharedMenu, '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();

addPlugin ( plugin )

 list.addPlugin('pullrefresh');

Or:

 list.addPlugin({
     type: 'pullrefresh',
     pullRefreshText: 'Pull to refresh...'

    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

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

center Ext.Component
chainable ch

Center this cfg-floated or positioned Component in its parent.

Returns

:Ext.Component

this

clearDelegatedListeners
private pri

Clears all listeners that were attached using the "delegate" event option. Users should not invoke this method directly. It is called automatically as part of normal clearListeners processing.

clearListeners

Removes all listeners for this object including the managed listeners

clearManagedListeners

Removes all managed listeners for this object.

constructor ( config )

Creates new Component.

Parameters

config :  Object

The standard configuration object.

createPlugin ( config ) : Ext.plugin.Abstract
private pri

Converts the provided type or config object into a plugin instance.

Parameters

config :  String / Object / Ext.plugin.Abstract

The plugin type, config object or instance.

Returns

:Ext.plugin.Abstract

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 Widget. This method should not be overridden in custom Widgets, because it sets the flags and does final cleanup that must go last. Instead, override doDestroy method to add functionality at destruction time.

destroyPlugin ( plugin ) : Ext.plugin.Abstract

Removes and destroys a plugin.

Note: Not all plugins are designed to be removable. Consult the documentation for the specific plugin in question to be sure.

Available since: 6.2.0

Parameters

plugin :  String / Ext.plugin.Abstract

The plugin or its id to remove.

Returns

:Ext.plugin.Abstract

plugin instance or null if not found.

disable

Disables this Component

doAddListener ( name, fn, scope, options, order, caller, manager )
private pri

Parameters

name :  Object

fn :  Object

scope :  Object

options :  Object

order :  Object

caller :  Object

manager :  Object

doDestroy

Perform the actual destruction sequence. This is the method to override in your subclasses to add steps specific to the destruction of custom Component.

If the Component is currently added to a Container it will first be removed from that Container. All Ext.Element references are also deleted and the Component is de-registered from Ext.ComponentManager.

As a rule of thumb, subclasses should destroy their child Components, Elements, 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

doSetComponent ( component )
private pri

Parameters

component :  Object

doUnsetComponent ( component )
private pri

Parameters

component :  Object

enable

Enables this Component

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.

findFloatParent
private pri

The method finds this floated component's floatParent. That means a DOM positioning container which acts as a root element for sibling floated components, and allows allows floated components to be absolutely positioned, and their encapsulating elements to be reordered to produce a visual stacking effect.

This component's element is appended to its floatParent.

There is a global floatParent element, created on demand when the first top level floated component is shown. This may be an item child of a container configured with cfg-floated: true, or a free floated component which is programatically shown.

Child items of components inside a floated component may also be configured floated. These are give a floatParent which is created on demand wrapping the nearest floated ancestor. This means that when that ancestor's element is brought to the top of the stack (by moving its element to the end of its own floatParent), the descendant elements will automatically remain above.

findPlugin ( type ) : Ext.plugin.Abstract

Retrieves plugin by its type alias. For example:

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: ['listpaging', 'pullrefresh']
 });

 list.findPlugin('pullrefresh').setPullRefreshText('Pull to refresh...');

Note: See also getPlugin.

Available since: 6.2.0

Parameters

type :  String

The Plugin's type as specified by the class's alias configuration.

Returns

:Ext.plugin.Abstract

plugin instance or null if not found.

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

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

fixReference
private pri

Sets up a reference on our current reference holder.

getAlignRegion ( component, alignment, options )
private pri

private pri

Gets the bubbling parent for an Observable

Returns

:Ext.util.Observable

The bubble parent. null is returned if no bubble target exists

getConfig ( [name], [peek] ) : Object

Defaults to: false

Returns

:Object

The config property value.

getCurrentAlignmentInfo
private pri

Current Alignment information from the last alignTo call

getElementConfig Object
protected pro

A template method for modifying the element config before it is processed. By default adds the result of this.getTemplate() as the children array of element if children were not specified in the original element config. Typically this method should not need to be implemented in subclasses. Instead the element property should be use to configure the element template for a given Widget subclass.

This method is called once when the first instance of each Widget subclass is created. The element config object that is returned is cached and used as the template for all successive instances. The scope object for this method is the class prototype, not the instance.

Returns

:Object

the element config object

getFloatParent Ext.Component
private pri

For cfg-floated components only.

Finds the owning cfg-floated component (if any) responsible for the base z-index stack position of this compoonent, and, if that component is cfg-relative, for the coordinate system in which this component is positioned.

If this is a top level floated component, this method will return null

Returns

:Ext.Component

The owning floated component or null if this component is top level floated.

getFloatWrap Ext.dom.Element
private pri

This method returns, or creates on demand the floatWrap element which wraps the passed floated component. It enables that floated component to act as a host for descendant floated components.

Returns

:Ext.dom.Element

The passed component's floatWrap element.

getFloatedStack ( selector )

Returns the stack of floated components in which this Component resides. This Component and all siblings at this level are returned.

Parameters

selector :  String / Function

A ComponentQuery selector, or a selection function which returns true to select a component.

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.

getParent Ext.Component

Returns the parent of this component, if it has one.

Returns

:Ext.Component

The parent of this component.

getPlugin ( id ) : Ext.plugin.Abstract

Retrieves a plugin by its id.

 var list = Ext.create({
     xtype: 'list',
     itemTpl: '<div class="item">{title}</div>',
     store: 'Items',

     plugins: {
         xclass: 'Ext.plugin.PullRefresh',
         id: 'foo'
     }
 });

 list.getPlugin('foo').setPullRefreshText('Pull to refresh...');

Note: See also findPlugin.

Available since: 6.2.0

Parameters

id :  String

The id of the plugin.

Returns

:Ext.plugin.Abstract

plugin instance or null if not found.

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.

getSize Object

Returns the height and width of the Component.

Returns

:Object

The current height and width of the Component.

width :  Number

height :  Number

getXTypes String

Returns this Component's xtype hierarchy as a slash-delimited string. For a list of all available xtypes, see the Ext.Component header.

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

Example usage:

var t = new Ext.field.Text();
alert(t.getXTypes());  // alerts 'component/field/textfield'

Returns

:String

The xtype hierarchy string.

hasConfig ( name )
private pri

Parameters

name :  String

hasListener ( eventName ) : Boolean

Checks to see if this object has any listeners for a specified event, or whether the event bubbles. The answer indicates whether the event needs firing or not.

Parameters

eventName :  String

The name of the event to check for

Returns

:Boolean

true if the event is being listened for or bubbles, else false

hasParent Boolean

Returns true if this component has a parent.

Returns

:Boolean

true if this component has a parent.

hide ( [animation] ) : Ext.Component
chainable ch

Hides this Component optionally using an animation.

Parameters

animation :  Object / Boolean (optional)

You can specify an animation here or a bool to use the hideAnimation config.

Returns

:Ext.Component

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

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

Initialize configuration for this class. a typical example:

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'

Parameters

instanceConfig :  Object

Returns

:Ext.Base

this

initElement
protected pro

Initializes the Element for this Widget instance. If this is the first time a Widget of this type has been instantiated the element config will be processed to create an Element. This Element is then cached on the prototype (see afterCachedConfig) so that future instances can obtain their element by simply cloning the Element that was cached by the first instance.

initElementListeners ( elementConfig )
private pri

Called for the first instance of this Widget to create an object that contains the listener configs for all of the element references keyed by reference name. The object is cached on the prototype and has the following shape:

_elementListeners: {
    element: {
        click: 'onClick',
        scope: this
    },
    fooReference: {
        tap: {
            fn: someFunction,
            delay: 100
        }
    }
}

The returned object is prototype chained to the _elementListeners object of its superclass, and each key in the object is prototype chained to object with the corresponding key in the superclass _elementListeners. This allows element listeners to be inherited and overridden when subclassing widgets.

This method is invoked with the prototype object as the scope

Parameters

elementConfig :  Object

initInheritedState ( inheritedState, [inheritedStateInner] )
protected pro

This method is called to initialize the inheritedState objects for this instance. This amounts to typically copying certain properties from the instance to the given object.

Available since: 5.0.0

Parameters

inheritedState :  Object

The state object for this instance.

inheritedStateInner :  Object (optional)

This object is only provided for containers.

initKeyMap
protected pro

This method should be called when the instance is ready to start listening for keyboard events. This is called automatically for Ext.Component and derived classes. In Classic Toolkit, this is done after the component is rendered.

insertFloatedDom
private pri

This method inserts this floated component's DOM into its owning floatParent.

invalidateInheritedState
private pri

This method marks the current inherited state as invalid. The next time a call is made to getInherited the objects will be recreated and initialized.

Available since: 5.0.0

Returns true if this Component is currently disabled.

Returns

:Boolean

true if currently disabled.

isHidden ( [deep] ) : Boolean

Returns true if this Component is currently hidden.

Parameters

Defaults to: false

Returns

:Boolean

true if currently hidden.

isSuspended ( [event] ) : Boolean

Checks if all events, or a specific event, is suspended.

Parameters

event :  String (optional)

The name of the specific event to check

Returns

:Boolean

true if events are suspended

isSyncing ( name ) : Boolean
private pri

Returns

:Boolean

true if the binding is syncing.

isVisible ( [deep] ) : Boolean

Returns true if this Component is currently visible.

Parameters

true to check if this component is visible and all parents are also visible.

Defaults to: false

Returns

:Boolean

true if currently visible.

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:

var t = new Ext.field.Text();
var isText = t.isXType('textfield'); // true
var isBoxSubclass = t.isXType('field'); // true, descended from Ext.field.Field
var isBoxInstance = t.isXType('field', true); // false, not a direct Ext.field.Field instance

Parameters

xtype :  String

The xtype to check for this Component.

shallow :  Boolean (optional)

false to check whether this Component is descended from the xtype (this is the default), or true to check whether this Component is directly of the specified xtype.

Returns

:Boolean

true if this component descends from the specified xtype, false otherwise.

lookupController ( [skipThis] ) : Ext.app.ViewController

Gets the controller that controls this view. May be a controller that belongs to a view higher in the hierarchy.

Available since: 5.0.1

Parameters

skipThis :  Boolean (optional)

true to not consider the controller directly attached to this view (if it exists).

Defaults to: false

Returns

:Ext.app.ViewController

The controller. null if no controller is found.

lookupReferenceHolder ( [skipThis] ) : Ext.app.ViewController / Ext.Container
private pri

Available since: 5.0.0

Parameters

skipThis :  Boolean (optional)

false to return this as the reference holder if this instance has set referenceHolder.

In this case, the reference connects not to this component but to the parent referenceHolder.

Defaults to: true

Returns

:Ext.app.ViewController / Ext.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 viewModel configured on this instance and only consider an inherited view model.

Defaults to: false

Returns

:Ext.app.ViewModel

makeBindableUpdater ( cfg ) : Function
private pri

Returns an update method for the given Config that will call publishState to ensure two-way bindings (via bind) as well as any publishes are updated. This method is cached on the cfg instance for re-use.

Available since: 5.0.0

Parameters

cfg :  Ext.Config

Returns

:Function

The updater function.

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.SomeGlobalSharedMenu, '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();

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.

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, ...);

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:

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:

order :  String (optional)

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

Combining Options

Using the options argument, it is possible to combine different types of listeners:

A delayed, one-time listener.

myPanel.on('hide', this.handleClick, this, {
    single: true,
    delay: 100
});

Attaching multiple handlers in 1 call

The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers and handler configs.

grid.on({
    itemclick: 'onItemClick',
    itemcontextmenu: grid.onItemContextmenu,
    destroy: {
        fn: function () {
            // function called within the 'altCmp' scope instead of grid
        },
        scope: altCmp // unique scope for the destroy handler
    },
    scope: grid       // default scope - provided for example clarity
});

Delegate

This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example:

var panel = Ext.create({
    xtype: 'panel',
    renderTo: document.body,
    title: 'Delegate Handler Example',
    frame: true,
    height: 220,
    width: 220,
    html: '<h1 class="myTitle">BODY TITLE</h1>Body content'
});

// The click handler will only be called when the click occurs on the
// delegate: h1.myTitle ("h1" tag with class "myTitle")
panel.on({
    click: function (e) {
        console.log(e.getTarget().innerHTML);
    },
    element: 'body',
    delegate: 'h1.myTitle'
 });

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();

onShowByErased ( component )
private pri

Parameters

component :  Ext.Component

owns ( element )
private pri

Returns true if the passed element is within the container tree of this component.

For example if a menu's submenu contains an Ext.form.field.Date, that top level menu owns the elements of the date picker. Using this method, you can tell if an event took place within a certain component tree.

Parameters

element :  Object

processElementConfig Object
private pri

Recursively processes the element templates for this class and its superclasses, ascending the hierarchy until it reaches a superclass whose element template has already been processed. This method is invoked using the prototype as the scope.

Returns

:Object

publishState ( [property], [value] )
protected pro

Publish this components state to the ViewModel. If no arguments are given (or if this is the first call), the entire state is published. This state is determined by the publishes property.

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.

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();

removeCls ( cls, [prefix], [suffix] )

Removes the given CSS class(es) from this Component's rendered element.

Parameters

cls :  String

The class(es) to remove.

prefix :  String (optional)

Optional prefix to prepend before each class.

Defaults to: ""

suffix :  String (optional)

Optional suffix to append to each class.

Defaults to: ""

removeDelegatedListener ( eventName, fn, scope )
private pri

Removes delegated listeners for a given eventName, function, and scope. Users should not invoke this method directly. It is called automatically by the framework as part of removeListener processing.

Parameters

eventName :  Object

fn :  Object

scope :  Object

removeListener ( eventName, fn, [scope] ) :
chainable ch

Removes an event handler.

Parameters

eventName :  String

The type of event the handler was associated with.

fn :  Function

The handler to remove. This must be a reference to the function passed into the addListener call.

scope :  Object (optional)

The scope originally specified for the handler. It must be the same as the scope argument specified in the original call to Ext.util.Observable#addListener or the listener will not be removed.

Convenience Syntax

You can use the addListener destroyable: true config option in place of calling un(). For example:

var listeners = cmp.on({
    scope: cmp,
    afterrender: cmp.onAfterrender,
    beforehide: cmp.onBeforeHide,
    destroyable: true
});

// Remove listeners
listeners.destroy();
// or
cmp.un(
    scope: cmp,
    afterrender: cmp.onAfterrender,
    beforehide: cmp.onBeforeHide
);

Exception - DOM event handlers using the element config option

You must go directly through the element to detach an event handler attached using the addListener element option.

panel.on({
    element: 'body',
    click: 'onBodyCLick'
});

panel.body.un({
    click: 'onBodyCLick'
});

Returns

Parameters

eventName :  String...

Multiple event names to resume.

resumeEvents ( [discardQueue] )

Resumes firing events (see suspendEvents).

If events were suspended using the queueSuspended parameter, then all events fired during event suspension will be sent to any listeners now.

showBy ( component, [alignment], [options] )

Shows this component by another component. If you specify no alignment, it will automatically position this component relative to the reference component.

For example, say we are aligning a Panel next to a Button, the alignment string would look like this:

[panel-vertical (t/b/c)][panel-horizontal (l/r/c)]-[button-vertical (t/b/c)][button-horizontal (l/r/c)]

where t = top, b = bottom, c = center, l = left, r = right.

Examples

  • tl-tr means top-left corner of the Panel to the top-right corner of the Button
  • tc-bc means top-center of the Panel to the bottom-center of the Button

You can put a '?' at the end of the alignment string to constrain the positioned element to the Ext.Viewport

// show `panel` by `button` using the default positioning (auto fit)
panel.showBy(button);

// align the top left corner of `panel` with the top right corner of `button` (constrained to viewport)
panel.showBy(button, "tl-tr?");

// align the bottom right corner of `panel` with the center left edge of `button` (not constrained by viewport)
panel.showBy(button, "br-cl");

The specific alignment.

options :  Object (optional)

An object containing options for the Ext.util.Region#alignTo method.

statics Ext.Class
protected pro

Get the reference to the class from which this object was instantiated. Note that unlike Ext.Base#self, this.statics() is scope-independent and it always returns the class from which it was called, regardless of what this points to during run-time

Ext.define('My.Cat', {
    statics: {
        totalCreated: 0,
        speciesName: 'Cat' // My.Cat.speciesName = 'Cat'
    },

    constructor: function() {
        var statics = this.statics();

        alert(statics.speciesName);     // always equals to 'Cat' no matter what 'this' refers to
                                        // equivalent to: My.Cat.speciesName

        alert(this.self.speciesName);   // dependent on 'this'

        statics.totalCreated++;
    },

    clone: function() {
        var cloned = new this.self();   // dependent on 'this'

        cloned.groupName = this.statics().speciesName;   // equivalent to: My.Cat.speciesName

        return cloned;
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',

    statics: {
        speciesName: 'Snow Leopard'     // My.SnowLeopard.speciesName = 'Snow Leopard'
    },

    constructor: function() {
        this.callParent();
    }
});

var cat = new My.Cat();                 // alerts 'Cat', then alerts 'Cat'

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

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

alert(My.Cat.totalCreated);             // alerts 3

Returns

:Ext.Class

suspendEvent ( eventName )

Suspends firing of the named event(s).
