ExtReact Docs Help

Introduction

The documentation for the ExtReact product diverges somewhat from the documentation of other Sencha products. The sections below describe documentation for all products except where indicated as unique to ExtReact.

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.

ExtReact component classes list the configurable name prominently at the top of the API class doc followed by the fully-qualified class name.

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

Or in the case of an ExtReact component class this indicates a member of type prop

- 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.

ExtReact component classes do not hoist the getter / setter methods into the prop. All methods will be described in the Methods section

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.

ExtReact 6.5.1


top

Button Ext.Button

Summary

This class provides a push button with many presentation options. There are various styles of Button you can create by mixing the icon, iconCls, iconAlign, ui, and text props.

Here is an example showing multiple button presentations.

Icons

As you can see in the above example, you can also create a button with just an icon using the iconCls prop. Simply include the Font Awesome class name as your iconCls prop's value.

Badges

Buttons can also have a badge on them, by using the badgeText prop.

Menus

You can assign a menu to a button by using the menu prop. This prop can be a reference to a Menu instance or a Menu prop object.

When assigning a menu to a button, an arrow is automatically added to the button. You can change the alignment of the arrow using the arrowAlign prop.

UI

Buttons also come with a range of different default UIs. Here are the included UIs available (if $include-button-uis is set to true):

  • normal - a basic gray button
  • back - a back button
  • forward - a forward button
  • round - a round button
  • action - shaded using the $active-color (dark blue by default)
  • decline - shaded using the $alert-color (red by default)
  • confirm - shaded using the $confirm-color (green by default)

You can also add "round" to each of the last three UI's to give it a round shape:

  • ui="action round"
  • ui="decline round"
  • ui="confirm round"

The default ui is normal.

You can also use the sencha-button-ui CSS Mixin to create your own UIs.

Children

The following Components (and their sub-components) may be included as children of Button:
String
Object
Menu
String
Object
No members found using the current filters

props

Optional Props

allowDepress : Boolean

true to allow user interaction to set pressed to false when the button is in the pressed state. Only valid when pressed is configured.

Defaults to:

true

Available since: 6.0.2

alwaysOnTop : Boolean / Number

A flag indicating that this component should be above its floated siblings.

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

Available since: 6.2.0

ariaAttributes : Object

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.

ariaDescribedBy : String
immutable imm

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
immutable imm

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
immutable imm

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.

arrow : Boolean

By default, if the button has a menu, an arrow icon is shown to indicate this.

Configure arrow: false to hide the menu arrow.

Defaults to:

true

arrowAlign : "right" / "bottom"

The side of the Button box to render the arrow if the button has an associated menu.

Defaults to:

'right'

autoEvent : String

Optional event name that will be fired instead of tap when the Button is tapped on.

Defaults to:

null

axisLock : Boolean

If true, then, when showBy or alignTo fallback on constraint violation only takes place along the major align axis.

That is, if alignment "l-r" is being used, and axisLock: true is used, then if constraints fail, only fallback to "r-l" is considered.

Defaults to:

null

badgeText : String

Optional badge text. Badges appear as small numbers, letters, or icons that sit on top of your button. For instance, a small red number indicating how many updates are available.

Defaults to:

null

border : Boolean

Enables or disables bordering on this component. The following values are accepted:

  • null or `true (default): Do nothing and allow the border to be specified by the theme.
  • false: suppress the default border provided by the theme.

Please note that enabling bordering via this config will not add a border-color or border-style CSS property to the component; you provide the border-color and border-style via CSS rule or style configuration (if not already provide by the theme).

Defaults to:

null

bottom : Number / String

The absolute bottom 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

buttonType : String

By default, all buttons have type="button". If a button is intended to be invoked as the default action button inside an FormPanel, then setting this to 'submit' will cause the button to be clicked whenever the ENTER key is pressed.

Defaults to:

'button'

Available since: 6.5.0

centered : Boolean

Configure this as true to have this Component centered within its Container. Setting this value to true 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:

false

cls : String / String[]

The CSS class to add to this widget's element, in addition to the baseCls. In many cases, this property will be specified by the derived widget class. See userCls for adding additional CSS classes to widget instances (such as items in a Container).

Defaults to:

null

constrainAlign : String / Ext.util.Region / Ext.dom.Element

A specification of the constraint to apply when showBy or alignTo is called to align a floated or positioned component.

Defaults to the parent container for positioned components (components which have their top, right, bottom or left set to move them out of their container's layout flow).

Defaults to the viewport for floated components.

May be a Ext.ComponentQuery selector to find an ancestor component to constrain within.

May be false to specify that constraining is not applied.

You may also specify an element, or a Ext.util.Region

contentEl : Ext.dom.Element / HTMLElement / String

The configured element will automatically be added as the content of this component. When you pass a string, we expect it to be an element id. If the content element is hidden, we will automatically show it.

Defaults to:

null

data : Object

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

Defaults to:

null

destroyMenu : Boolean

Whether or not to destroy any associated menu when this button is destroyed. In addition, a value of true for this prop will destroy the currently bound menu when a new menu is set in setMenu unless overridden by that method's destroyMenu function argument.

Defaults to:

true

disabled : Boolean

Whether or not this component is disabled

Defaults to:

null

displayed : Boolean

Set to true to call show and false to call hide. Unlike the hidden config, changing this config will potentially involve animations to show or hide the component.

Defaults to:

null

Available since: 6.5.0

docked : String

The dock position of this component in its container. Can be left, top, right or bottom.

Notes

You must use a HTML5 doctype for docked bottom to work. To do this, simply add the following code to the HTML file:

<!doctype html>

So your index.html file should look a little like this:

<!doctype html>
<html>
    <head>
        <title>MY application title</title>
        ...

Defaults to:

null

draggable : Boolean / Object / Ext.drag.Source

Configuration options to make this Component draggable

Defaults to:

null

enableToggle : Boolean

Allows this button to have the pressed state toggled via user interaction.

Defaults to:

false

Available since: 6.0.2

eventHandlers : Object
immutable imm

Properties

click : String

Defaults to: 'onClick'

factoryConfig : Object
readonly ro

If this property is specified by the target class of this mixin its properties are used to configure the created Ext.Factory.

flex : Number / String / Object

The flex of this item if this item item is inside a Ext.layout.HBox or Ext.layout.VBox layout.

You can also update the flex of a component dynamically using the Ext.layout.FlexBox#setItemFlex method.

When supplied as a string or number this option supports the same syntax as CSS flex. For example:

flex: '1 2 auto'

sets flex-grow property to 0, flex-shrink to 2 and flex-basis to 'auto'.

The default flex-shrink value for box layout items is set to 0 in the stylesheet, which is different from the browser's default flex-shrink value of 1. This accommodates the majority use case for applications since where non-flexed components are typically not expected to shrink smaller than their default size.

For convenience when only a single number is supplied it is used as the value for both flex-grow and flex-shrink, for example flex: 3 is the same as flex: '3 3'

An object form is also accepted:

flex: {
    grow: 1,
    shrink: 2,
    basis: 'auto'
}

When the object form is supplied shrink always defaults to 0 regardless of the value of grow.

Although 'auto' is the default value for flex-basis, flex-basis defaults to 0% when flex is supplied as a single numeric or string value (e.g. flex: 1). If this behavior is not desired either explicitly set flex-basis to 'auto' or use the object form to set only grow and/or shrink:

flex: {
    grow: 2
}

floated : Boolean

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.

Defaults to:

false

Available since: 6.2.0

focusCls : String
immutable imm

CSS class that will be added to focused component's focusClsEl, and removed when component blurs.

Defaults to:

'x-focused'

focusClsEl : Ext.dom.Element
readonly ro

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

focusEl : Ext.dom.Element
readonly ro

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'

fullscreen : Boolean
immutable imm

Force the component to take up 100% width and height available, by adding it to Ext.Viewport.

handler : Function

The handler function to run when the Button is tapped on.

Defaults to:

null

height : Number / String

The height 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

hidden : Boolean

Whether or not this Component is hidden (its CSS display property is set to none).

Defaults to true for floated Components.

Defaults to:

null

hideAnimation : String / Mixed

Animation effect to apply when the Component is being hidden. Typically you want to use an outbound animation type such as 'fadeOut' or 'slideOut'. For more animations, check the Ext.fx.Animation#type config.

Defaults to:

null

hideMode : 'clip' / 'display' / 'offsets' / 'opacity' / 'visibility'

A String which specifies how this component's DOM element will be hidden. The accepted values are any of these:

Hiding using display results in having no dimensions as well as resetting scroll positions to 0.

The other modes overcome this but may have different trade-offs in certain circumstances.

Defaults to:

'display'

Available since: 6.5.0

hideOnMaskTap : Boolean

When using a modal Component, setting this to true will hide the modal mask and the Container when the mask is tapped on.

Defaults to:

null

html : String

The HTML to put in this button.

If you want to just add text, please use the text configuration.

icon : String

Url to the icon image to use if you want an icon to appear on your button.

Defaults to:

false

iconAlign : 'top' / 'right' / 'bottom' / 'left'

The position within the Button to render the icon Options are: top, right, bottom, left and center (when you have no text set).

Defaults to:

'left'

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 prop 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:

Defaults to:

null

id : String
immutable imm

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 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.

isObservable : Boolean
readonly ro

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

Defaults to:

true

itemId : String

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.

keyMap : Object

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.

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.

keyMapEnabled : Boolean

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

left : Number / String

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

listeners : Object

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'); }
        }
    }
});

margin : Number / String

The margin to use on this Component. Can be specified as a number (in which case all edges get the same margin) or a CSS string like '5 10 10 10'

Defaults to:

null

maxHeight : Number / String

The maximum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size. Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)

Defaults to:

null

maxWidth : Number / String

The maximum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size. Note that this config will not apply if the Component is 'positioned' (absolutely positioned or centered)

Defaults to:

null

menuAlign : String

The position to align the menu to (see Ext.util.Positionable#alignTo for more details).

Defaults to:

'tl-bl?'

minHeight : Number / String

The minimum height of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

minWidth : Number / String

The minimum width of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. If set to auto, it will set the width to null meaning it will have its own natural size.

Defaults to:

null

modal : Boolean

true to make this Component modal. This will create a mask underneath the Component that covers its parent and does not allow the user to interact with any other Components until this Component is dismissed.

Defaults to:

null

modelValidation : Boolean
immutable imm

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

When set to true by a component (or by an ancestor container), the validators of for any {@Ext.data.Model record} fields will be used wherever the value is bound to such data fields.

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}'
     }]
 }

Defaults to:

null

Available since: 6.5.0

name : String
immutable imm

Name for the widget to be used with Ext.Container#lookupName et al.

Defaults to:

null

padding : Number / String

The padding to use on this Component. Can be specified as a number (in which case all edges get the same padding) or a CSS string like '5 10 10 10'

Defaults to:

null

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

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
     }]
 });

pressed : Boolean

Sets the pressed state of the button.

Defaults to:

false

Available since: 6.0.2

pressedDelay : Number / Boolean

The amount of delay between the tapstart and the moment we add the pressingCls (in milliseconds). Settings this to true defaults to 100ms.

Defaults to:

0

publishes : String

Defaults to:

'pressed'

record : Ext.data.Model

A model instance which updates the Component's html based on it's tpl. Similar to the data configuration, but tied to to a record to make allow dynamic updates. This must be a model instance and not a configuration of one.

Defaults to:

null

relative : Boolean

Only valid when a component is cfg-floated

Configure this as true if you require descendant floated components to be positioned relative to this component's coordinate space, not the viewport's coordinate space.

Note: The coordinate space is this Component's encapsulating element's area. Not that of the inner element in which static child items are rendered by the layout.

Defaults to:

false

Available since: 6.2.0

right : Number / String

The absolute right 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

ripple : Boolean / Object / String

Set to truthy, Color or Object value for the ripple.

Available since: 6.5.0

Properties

color : String

The background color of the ripple.

position : Array

Position for the ripple to start at [x,y]. Determines if a Ripple effect should happen whenever this element is pressed.

For example: { ripple: true }

Or:

 {
     ripple: {
         color: 'red'
     }
 }

For complex components, individual elements can suppress ripples by adding the x-no-ripple class to disable rippling for a tree of elements.

scope : Object

The scope (this reference) in which the configured handler will be executed, unless the scope is a ViewController method name.

Defaults to:

null

scrollable : Boolean / String / Object

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

selfAlign : String

Specifies the self alignment of this widget in a box layout

shadow : Boolean

Configure as true for the component to have a drop shadow. 'false' will suppress any default shadow. By default the theme will determine the presence of a shadow.

Available since: 6.2.0

shim : Boolean

Only valid when a component is cfg-floated

Configure as true for the component to use an <iframe> as an underlay to ensure certain non-standard browser plugins are occluded by this component.

Defaults to:

false

Available since: 6.2.0

showAnimation : String / Mixed

Animation effect to apply when the Component is being shown. Typically you want to use an inbound animation type such as 'fadeIn' or 'slideIn'. For more animations, check the Ext.fx.Animation#type config.

Defaults to:

null

stretchMenu : Boolean
immutable imm

Configure as true if the cfg of this button's. menu should at least match the width of this button. An minWidth explicit minWidth on the menu will override this.

Defaults to:

false

Available since: 6.5.1

style : String / Object

Additional CSS styles that will be rendered into an inline style attribute when the widget is rendered.

You can pass either a string syntax:

style: 'background:red'

Or by using an object:

style: {
    background: 'red'
}

When using the object syntax, you can define CSS Properties by using a string:

style: {
    'border-left': '1px solid red'
}

Although the object syntax is much easier to read, we suggest you to use the string syntax for better performance.

Defaults to:

null

tabIndex : Number

DOM tabIndex attribute for this component's focusEl.

Defaults to:

null

text : String

The Button text.

Defaults to:

null

textAlign : "left" / "right" / "center"

Defaults to:

'center'

Available since: 6.0.1

toFrontOnShow : Boolean

True to automatically call toFront when a cfg-floated Component is shown.

Defaults to:

true

toggleHandler : Function

Properties

button : Ext.Button

This Button.

pressed : Boolean

This Button's new pressed state. The handler function to run when the Button is toggled. Supplying this configuration implies enableToggle is true.

top : Number / String

The absolute top 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

touchAction : Object
immutable imm

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 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
        }
    }
});

Defaults to:

true

tpl : String / String[] / Ext.Template / Ext.XTemplate[]

A string, array of strings, or a function that returns JSX.

tpl = data =>

{data.first_name} {data.last_name}

Note The data configuration must be set for any content to be shown in the component when using this configuration.

Defaults to:

null

tplWriteMode : String

The Ext.(X)Template method to use when updating the content area of the Component.

Valid modes are:

  • append
  • insertAfter
  • insertBefore
  • insertFirst
  • overwrite

Defaults to:

'overwrite'

ui : String

The ui style to render this button with. The valid default options are:

  • null - a basic gray button (default).
  • 'back' - a back button.
  • 'forward' - a forward button.
  • 'round' - a round button.
  • 'plain'
  • 'action' - shaded using the $active-color (dark blue by default).
  • 'decline' - shaded using the $alert-color (red by default).
  • 'confirm' - shaded using the $confirm-color (green by default).

You can also append -round to each of the last three UI's to give it a round shape:

  • action-round
  • decline-round
  • confirm-round

Defaults to:

null

userCls : String / String[]
immutable imm

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:

true

userSelectable : Boolean / String / Object

Set to true to allow users to select text within this component.

Can also be any valid value for the CSS3 user-select property.

A value of true implies auto, while false implies none.

May also be an object keyed by child element name.

By default, the user cannot click+drag+select text/elements of the UI. Applications may want to enable user selection for specific DOM elements, such as the bodyElement of a component used as a tab panel. The tab and tab text would not be user selectable in this example, but the content area when the tab is selected would.

 userSelectable: {
     element: true,       // optionally allow the element to be user selectable
     bodyElement: true    // optionally allow the component's body element to be user selectable
 }

Defaults to:

false

Available since: 6.5.1

value : String / Number

The value of this button. Only applicable when used as an item of a SegmentedButton.

Defaults to:

null

weight : Number

This value controls this item's order in a weighted Container (see parent).

Lower values gravitate towards the start of the container - the top in vertical layouts, the locale start side in horizontal layouts.

Defaults to:

0

width : Number / String

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

x : Number

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

xtype : String
immutable imm

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.

Defaults to:

"component"

y : Number

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

zIndex : Number

The z-index to give this Component when it is rendered.

Not valid for cfg-floated Components. The Z ordering of cfg-floated Components is managed by ordering of the DOM elements.

Defaults to:

null

children

menu : Menu / String / Object

A Menu to show when the Button is clicked / tapped.

Example snippet:

<Button text="Style">
    <Menu>
        <MenuItem text="Single" value="single"/>
        <MenuItem text="Double" value="double"/>
    </Menu>
</Button>

Defaults to:

null

tooltip : String / Object

The ToolTip for this component.

<Button text="Basic Tip">
    <ToolTip>A simple tooltip</ToolTip>
</Button>

Defaults to:

null

methods

Instance Methods

addListener ( 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 arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these 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.

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 )

Adds a plugin. For example:

 list.addPlugin('pullrefresh');

Or:

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

Available since: 6.2.0

Parameters

plugin :  Object/String/Ext.plugin.Abstract

The plugin or config object or alias to add.

clearListeners

Removes all listeners for this object including the managed listeners

clearManagedListeners

Removes all managed listeners for this object.

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.

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.

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.

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] )

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.

focus ( [selectText] ) : Boolean

Try to focus this component.

If this component is disabled or otherwise not focusable, a close relation will be targeted for focus instead to keep focus localized for keyboard users.

Parameters

selectText :  Boolean/Number[] (optional)

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.

Returns

:Boolean

true if focus target was found and focusing was attempted, false if no focusing attempt was made.

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.

getMenu : Menu / String / Object

Sets the value of menu

getPlugin ( id ) : Ext.plugin.Abstract

The name of the event to check for

Returns

:Boolean

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

isAncestor ( possibleDescendant )

Determines whether this Component is an ancestor of the passed Component. This will return true if the passed Component is anywhere within the subtree beneath this Component.

Parameters

possibleDescendant :  Ext.Component

The Component to test for presence within this Component's subtree.

isDescendantOf ( ancestor ) : Boolean

Determines whether this component is the descendant of a passed component.

Parameters

ancestor :  Ext.Component

A Component which may contain this Component.

Returns

:Boolean

true if the component is the descendant of the passed component, otherwise false.

isFocusable ( [deep] ) : Boolean

Determine if this Focusable can receive focus at this time.

Note that Containers can be non-focusable themselves while delegating focus treatment to a child Component; see Container for more information.

Parameters

deep :  Boolean (optional)

Optionally determine if the container itself is focusable, or if container's focus is delegated to a child component and that child is focusable.

Defaults to: false

Returns

:Boolean

True if component is focusable, false if not.

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

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 arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these 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.

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();

onAfter ( eventName, fn, [scope], [options] )

Appends an after-event handler.

Same as addListener with order set to 'after'.

Parameters

eventName :  String/String[]/Object

The name of the event to listen for.

fn :  Function/String

The method the event invokes.

scope :  Object (optional)

The scope for fn.

options :  Object (optional)

An object containing handler configuration.

onBefore ( eventName, fn, [scope], [options] )

Appends a before-event handler. Returning false from the handler will stop the event.

Same as addListener with order set to 'before'.

Parameters

eventName :  String/String[]/Object

The name of the event to listen for.

fn :  Function/String

The method the event invokes.

scope :  Object (optional)

The scope for fn.

options :  Object (optional)

An object containing handler configuration.

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();

removeListener ( eventName, fn, [scope] )

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'
});

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.

scope :  Object (optional)

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

removePlugin ( plugin, [destroy] ) : Ext.plugin.Abstract

Removes and (optionally) 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

The plugin or its id to remove.

destroy :  Boolean (optional)

Pass true to not call destroy() on the plugin.

Returns

:Ext.plugin.Abstract

resumeEvent ( eventName )

Resumes firing of the named event(s).

After calling this method to resume events, the events will fire when requested to fire.

Note that if the suspendEvent method is called multiple times for a certain event, this converse method will have to be called the same number of times for it to resume firing.

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.

Parameters

discardQueue :  Boolean (optional)

true to prevent any previously queued events from firing while we were suspended. See suspendEvents.

suspendEvent ( eventName )

Suspends firing of the named event(s).

After calling this method to suspend events, the events will no longer fire when requested to fire.

Note that if this is called multiple times for a certain event, the converse method resumeEvent will have to be called the same number of times for it to resume firing.

Parameters

eventName :  String...

Multiple event names to suspend.

suspendEvents ( queueSuspended )

Suspends the firing of all events. (see resumeEvents)

Parameters

queueSuspended :  Boolean

true to queue up suspended events to be fired after the resumeEvents call instead of discarding all suspended events.

un ( eventName, fn, [scope] )

Shorthand for removeListener. 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'
});

unAfter ( eventName, fn, [scope], [options] )

Removes a before-event handler.

Same as removeListener with order set to 'after'.

Parameters

eventName :  String/String[]/Object

The name of the event the handler was associated with.

fn :  Function/String

The handler to remove.

scope :  Object (optional)

The scope originally specified for fn.

options :  Object (optional)

Extra options object.

unBefore ( eventName, fn, [scope], [options] )

Removes a before-event handler.

Same as removeListener with order set to 'before'.

Parameters

eventName :  String/String[]/Object

The name of the event the handler was associated with.

fn :  Function/String

The handler to remove.

scope :  Object (optional)

The scope originally specified for fn.

options :  Object (optional)

Extra options object.

up ( [selector], [limit] ) : Ext.Container

Walks up the ownership hierarchy looking for an ancestor Component which matches the passed simple selector.

Example:

var owningTabPanel = grid.up('tabpanel');

Parameters

selector :  String (optional)

The simple selector to test.

limit :  String/Number/Ext.Component (optional)

This may be a selector upon which to stop the upward scan, or a limit of the number of steps, or Component reference to stop on.

Returns

:Ext.Container

The matching ancestor Container (or undefined if no match was found).

Static Methods

override ( members ) : Ext.Base
static sta

Override members of this class. Overridden methods can be invoked via Ext.Base#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).
