Ext.button.Button

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

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

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

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

Available since: Ext 2

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

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

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

This defaults to true for the Window class.

Defaults to: false

Available since: 4.0.0

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

Defaults to: false

Available since: 4.0.0

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

Defaults to: false

Available since: Ext 2

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

Available since: 4.0.0

An array describing the child elements of the Component. Each member of the array is an object with these properties:

• name - The property name on the Component for the child element.
• itemId - The id to combine with the Component's id that is the id of the child element.
• id - The id of the child element.

If the array member is a string, it is equivalent to { name: m, itemId: m }.

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

Ext.create('Ext.Component', {
    renderTo: Ext.getBody(),
    renderTpl: [
        '<h1 id="{id}-title">{title}</h1>',
        '<p>{msg}</p>',
    ],
    renderData: {
        title: "Error",
        msg: "Something went wrong"
    },
    childEls: ["title"],
    listeners: {
        afterrender: function(cmp){
            // After rendering the component will have a title property
            cmp.title.setStyle({color: "red"});
        }
    }
});

A more flexible, but somewhat slower, approach is renderSelectors.

Available since: 4.0.5

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

Available since: 4.0.0

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

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

Notes:

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

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

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

Available since: Ext 3

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

Available since: Ext 3

CSS class to add when the Component is disabled. Defaults to 'x-item-disabled'.

Defaults to: 'x-item-disabled'

Available since: 4.0.0

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

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

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

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

Defaults to: false

Available since: 4.0.0

Overrides: Ext.AbstractComponent.draggable

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

Components such as Windows and Menus are floating by default.

Floating Components that are programatically rendered will register themselves with the global ZIndexManager

Floating Components as child items of a Container

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

When configured as floating, Components acquire, at render time, a ZIndexManager which manages a stack of related floating Components. The ZIndexManager brings a single floating Component to the top of its stack when the Component's toFront method is called.

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

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

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

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

Defaults to: false

Available since: 4.0.0

Overrides: Ext.AbstractComponent.floating

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

Defaults to: true

Available since: 4.0.0

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

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

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

Available since: 4.0.0

The height of this component in pixels.

Available since: 4.0.0

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

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

Defaults to: 'display'

Available since: Ext 1

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

Defaults to: ''

Available since: Ext 3

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 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.

Note: to access the container of a Component see ownerCt.

Defaults to an auto-assigned id.

Available since: Ext 1

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.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.

var c = new Ext.panel.Panel({ //
    height: 300,
    renderTo: document.body,
    layout: 'auto',
    items: [
        {
            itemId: 'p1',
            title: 'Panel 1',
            height: 150
        },
        {
            itemId: 'p2',
            title: 'Panel 2',
            height: 150
        }
    ]
})
p1 = c.getComponent('p1'); // not the same as Ext.getCmp()
p2 = p1.ownerCt.getComponent('p2'); // reference via a sibling

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

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

Available since: Ext 3

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 Components

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'); }
        }
    }
});

Available since: 1.1.0

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

Available since: 4.0.0

Only valid when a sibling element of a Splitter within a VBox or HBox layout.

Specifies that if an immediate sibling Splitter is moved, the Component on the other side is resized, and this Component maintains its configured flex value.

Defaults to: false

Available since: 4.0.0

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

Available since: 4.0.0

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

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

Available since: 4.0.0

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

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

Available since: 4.0.0

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

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

Available since: 4.0.0

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

Available since: 4.0.0

An object or array of objects that will provide custom functionality for this component. The only requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.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.

Available since: Ext 2

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

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

See renderSelectors and childEls for usage examples.

Available since: Ext JS 4.0.7

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

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

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

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

For a faster, but less flexible, alternative that achieves the same end result (properties for child elements on the Component after render), see childEls and addChildEls.

Available since: 4.0.0

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

Notes:

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

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

See render also.

Available since: Ext 2

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

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

Available since: 4.0.0

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

Defaults to: 'all'

Available since: 4.0.0

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

Defaults to: 100

Available since: 4.0.6

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

Defaults to: 'sides'

Available since: 4.0.0

An array of events that, when fired, should trigger this object to save its state. Defaults to none. stateEvents may be any type of event supported by this object, including browser or custom events (e.g., ['click', 'customerchange']).

See stateful for an explanation of saving and restoring object state.

Available since: 4.0.0

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

See stateful for an explanation of saving and restoring state.

Available since: 4.0.0

A flag which causes the object to attempt to restore the state of internal properties from a saved state on startup. The object must have a stateId for state to be managed. Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a object.

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

To set the state provider for the current page:

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

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

To save state, a stateful object first serializes its state by calling getState. By default, this function does nothing. The developer must provide an implementation which returns an object hash which represents the restorable state of the object.

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

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

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

You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events.

Defaults to: true

Available since: 4.0.0

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

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

Available since: Ext 1

The class that is added to the content target when you set styleHtmlContent to true.

Defaults to: 'x-html'

Available since: 4.0.0

True to automatically style the html inside the content target of this component (body for panels).

Defaults to: false

Available since: 4.0.0

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

Defaults to: true

Available since: 4.0.0

An Ext.Template, Ext.XTemplate or an array of strings to form an Ext.XTemplate. Used in conjunction with the data and tplWriteMode configurations.

Available since: Ext 3

The Ext.(X)Template method to use when updating the content area of the Component. See Ext.XTemplate.overwrite for information on default mode.

Defaults to: 'overwrite'

Available since: Ext 3

A set style for a component. Can be a string or an Array of multiple strings (UIs)

Defaults to: 'default'

Available since: 4.0.0

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

Defaults to: []

Available since: 4.0.0

The width of this component in pixels.

Available since: 4.0.0

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

You can define your own xtype on a custom 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.

Only present for floating Components which were inserted as descendant items of floating Containers.

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

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

For example, the dropdown BoundList of a ComboBox which is in a Window will have the Window as its floatParent

Only present for floating Components after they have been rendered.

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

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

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

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

For floating Components which are added to a Container, the ZIndexManager is acquired from the first ancestor Container found which is floating, or if not found the global ZIndexManager is used.

Adds a CSS class to the top level element representing this component.

Available since: 4.0.0

Parameters

• cls : String

  The CSS class name to add

Returns

• Ext.Component

  Returns the Component to allow method chaining.

Adds a cls to the uiCls array, which will also call addUIClsToElement and adds to all elements of this component.

Available since: 4.0.0

Parameters

• cls : String/String[]

  A string or an array of strings to add to the uiCls

• skip : Object

  (Boolean) skip True to skip adding it to the class and do it later (via the return)

Adds the specified events to the list of events which this Observable may fire.

Available since: 1.1.0

Parameters

• o : Object/String

  Either an object with event names as properties with a value of true or the first event name string if multiple event names are being passed as separate parameters. Usage:

  this.addEvents({
      storeloaded: true,
      storecleared: true
  });
  

• more : String... (optional)

  Additional event names if multiple event names are being passed as separate parameters. Usage:

  this.addEvents('storeloaded', 'storecleared');
  

Available since: 4.0.6

Parameters

• members : Object

Returns

• Ext.Base

  this

Appends an event handler to this object.

Available since: 4.0.0

Parameters

• eventName : String

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

• fn : Function

  The method the event invokes. Will be called with arguments given to 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: Unlike in ExtJS 3.x, 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.

  • target : 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 Components. The name of a Component property which references an element to add a listener to.

    This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

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

  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 events. For example:

  myGridPanel.on({
      cellClick: this.onCellClick,
      mouseover: this.onMouseOver,
      mouseout: this.onMouseOut,
      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},
      mouseover: {fn: panel.onMouseOver, scope: panel}
  });

Available since: 4.0.0

Parameters

• config : Object

Perform custom animation on this object.

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

The sole parameter is an object which specifies start property values, end property values, and properties which describe the timeline. Of the properties listed below, only to is mandatory.

Properties include

• from
  An object which specifies start values for the properties being animated. If not supplied, properties are animated from current settings. The actual properties which may be animated depend upon ths object being animated. See the sections below on Element and Component animation.
• to
  An object which specifies end values for the properties being animated.
• duration
  The duration in milliseconds for which the animation will run.
• easing
  A string value describing an easing type to modify the rate of change from the default linear to non-linear. Values may be one of:

  • ease
  • easeIn
  • easeOut
  • easeInOut
  • backIn
  • backOut
  • elasticIn
  • elasticOut
  • bounceIn
  • bounceOut
• keyframes
  This is an object which describes the state of animated properties at certain points along the timeline. it is an object containing properties who's names are the percentage along the timeline being described and who's values specify the animation state at that point.
• listeners
  This is a standard listeners configuration object which may be used to inject behaviour at either the beforeanimate event or the afteranimate event.

Animating an Element

• x
  The page X position in pixels.
• y
  The page Y position in pixels
• left
  The element's CSS left value. Units must be supplied.
• top
  The element's CSS top value. Units must be supplied.
• width
  The element's CSS width value. Units must be supplied.
• height
  The element's CSS height value. Units must be supplied.
• scrollLeft
  The element's scrollLeft value.
• scrollTop
  The element's scrollLeft value.
• opacity
  The element's opacity value. This must be a value between 0 and 1.

Be aware than animating an Element which is being used by an Ext Component without in some way informing the Component about the changed element state will result in incorrect Component behaviour. This is because the Component will be using the old state of the element. To avoid this problem, it is now possible to directly animate certain properties of Components.

Animating a Component

• x
  The Component's page X position in pixels.
• y
  The Component's page Y position in pixels
• left
  The Component's left value in pixels.
• top
  The Component's top value in pixels.
• width
  The Component's width value in pixels.
• width
  The Component's width value in pixels.
• dynamic
  Specify as true to update the Component's layout (if it is a Container) at every frame of the animation. Use sparingly as laying out on every intermediate size change is an expensive operation.

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

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

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

Available since: 4.0.0

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

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.override(Ext.form.field.Base, {
    //  Add functionality to Field's initComponent to enable the change event to bubble
    initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
        this.enableBubble('change');
    }),

    //  We know that we want Field's events to bubble directly to the FormPanel.
    getBubbleTarget : function() {
        if (!this.formPanel) {
            this.formPanel = this.findParentByType('form');
        }
        return this.formPanel;
    }
});

var myForm = new Ext.formPanel({
    title: 'User Details',
    items: [{
        ...
    }],

Returns the next node in the Component tree in tree traversal order.

Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree to attempt to find a match. Contrast with nextSibling.

Available since: 4.0.0

Parameters

• selector : String (optional)

  A ComponentQuery selector to filter the following nodes.

Returns

• Ext.Component

  The next node (or the next node which matches the selector). Returns null if there is no matching node.

Returns the next sibling of this Component.

Optionally selects the next sibling which matches the passed ComponentQuery selector.

May also be refered to as next()

Note that this is limited to siblings, and if no siblings of the item match, null is returned. Contrast with nextNode

Available since: 4.0.0

Parameters

• selector : String (optional)

  A ComponentQuery selector to filter the following items.

Returns

• Ext.Component

  The next sibling (or the next sibling which matches the selector). Returns null if there is no matching sibling.

Shorthand for addListener.

Appends an event handler to this object.

Available since: 1.1.0

Parameters

• eventName : String

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

• fn : Function

  The method the event invokes. Will be called with arguments given to 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: Unlike in ExtJS 3.x, 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.

  • target : 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 Components. The name of a Component property which references an element to add a listener to.

    This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

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

  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 events. For example:

  myGridPanel.on({
      cellClick: this.onCellClick,
      mouseover: this.onMouseOver,
      mouseout: this.onMouseOut,
      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},
      mouseover: {fn: panel.onMouseOver, scope: panel}
  });
