DOM events from Ext JS Components

\n\n

While some Ext JS Component classes export selected DOM events (e.g. \"click\", \"mouseover\" etc), this is usually\nonly 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\nchild element of a Component, we need to specify the element option to identify the Component property to add a\nDOM listener to:

\n\n

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

models : String/String[]

Array of models to require from AppName.model namespace. For example:

\n\n

 Ext.define(\"MyApp.controller.Foo\", {\n     extend: \"Ext.app.Controller\",\n     models: ['User', 'Vehicle']\n });\n

\n\n

This is equivalent of:

\n\n

 Ext.define(\"MyApp.controller.Foo\", {\n     extend: \"Ext.app.Controller\",\n     requires: ['MyApp.model.User', 'MyApp.model.Vehicle'],\n\n     getUserModel: function() {\n         return this.getModel(\"User\");\n     },\n\n     getVehicleModel: function() {\n         return this.getModel(\"Vehicle\");\n     }\n });\n

Ext.app.Application

The list of namespace prefixes used in the application to resolve dependencies\nlike Views and Stores:

\n\n

 Ext.application({\n     name: 'MyApp',\n\n     namespaces: ['Common.code'],\n\n     controllers: [ 'Common.code.controller.Foo', 'Bar' ]\n });\n\n Ext.define('Common.code.controller.Foo', {\n     extend: 'Ext.app.Controller',\n\n     models: ['Foo'],    // Loads Common.code.model.Foo\n     views:  ['Bar']     // Loads Common.code.view.Bar\n });\n\n Ext.define('MyApp.controller.Bar', {\n     extend: 'Ext.app.Controller',\n\n     models: ['Foo'],    // Loads MyApp.model.Foo\n     views:  ['Bar']     // Loads MyApp.view.Bar\n });\n

\n\n

You don't need to include main namespace (MyApp), it will be added to the list\nautomatically.

Defaults to: []

paths : Object

Additional load paths to add to Ext.Loader. ...

Additional load paths to add to Ext.Loader.\nSee Ext.Loader.paths config for more details.

refs : Object[]

Array of configs to build up references to views on page. ...

Array of configs to build up references to views on page. For example:

\n\n

 Ext.define(\"MyApp.controller.Foo\", {\n     extend: \"Ext.app.Controller\",\n\n     refs: [{\n         ref: 'list',\n         selector: 'grid'\n     }],\n });\n

\n\n

This will add method getList to the controller which will internally use\nExt.ComponentQuery to reference the grid component on page.

\n\n

The following fields can be used in ref definition:

\n\n

ref - name of the reference.
selector - Ext.ComponentQuery selector to access the component.
autoCreate - True to create the component automatically if not found on page.
forceCreate - Forces the creation of the component every time reference is accessed\n(when get<REFNAME> is called).
xtype - Used to create component by its xtype with autoCreate or forceCreate. If\nyou don't provide xtype, an Ext.Component instance will be created.

\n\n

 Ext.define(\"MyApp.controller.Foo\", {\n     extend: \"Ext.app.Controller\",\n     stores: ['Users', 'Vehicles']\n });\n

\n\n

This is equivalent to:

 Ext.define(\"MyApp.controller.Foo\", {\n     extend: \"Ext.app.Controller\",\n     views: ['List', 'Detail']\n });\n

\n\n

This is equivalent of:

eventsSuspended : Numberprivate

Initial suspended call count. ...

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

Defaults to: 0

hasListeners : Objectreadonly

This object holds a key for any event that has a listener. ...

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

\n\n

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

\n\n

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

\n

Overrides: Ext.app.Controller.constructor

addEvents( eventNames )

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

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

Parameters

eventNames : Object/String...
Either an object with event names as properties with\na value of true. For example:
\n\n
```
this.addEvents({\n    storeloaded: true,\n    storecleared: true\n});\n
```
\n\n
Or any number of event names as separate parameters. For example:
\n\n
```
this.addEvents('storeloaded', 'storecleared');\n
```
\n

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

Appends an event handler to this object. ...

Appends an event handler to this object. For example:

\n\n

myGridPanel.on(\"mouseover\", this.onMouseOver, this);\n

\n\n

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

\n\n

myGridPanel.on({\n    cellClick: this.onCellClick,\n    mouseover: this.onMouseOver,\n    mouseout: this.onMouseOut,\n    scope: this // Important. Ensure \"this\" is correct during handler execution\n});\n

\n\n

One can also specify options for each event handler separately:

\n\n

myGridPanel.on({\n    cellClick: {fn: this.onCellClick, scope: this, single: true},\n    mouseover: {fn: panel.onMouseOver, scope: panel}\n});\n

\n\n

Names of methods in a specified scope may also be used. Note that\nscope MUST be specified to use this option:

\n\n

myGridPanel.on({\n    cellClick: {fn: 'onCellClick', scope: this, single: true},\n    mouseover: {fn: 'onMouseOver', scope: panel}\n});\n

Parameters

eventName : String/Object
The name of the event to listen for.\nMay also be an object who's property names are event names.
\n\n
fn : Function (optional)
The method the event invokes, or if scope is specified, the name* of the method within\nthe specified scope. Will be called with arguments\ngiven to fireEvent plus the options parameter described below.
\n\n
scope : Object (optional)
The scope (this reference) in which the handler function is\nexecuted. If omitted, defaults to the object which fired the event.
\n\n
options : Object (optional)
An object containing handler configuration.
\n\n\n\n\n
Note: Unlike in ExtJS 3.x, the options object will also be passed as the last\nargument to every event handler.
\n\n\n\n\n
This object may contain any of the following properties:
\n\n
- scope : Object
  The scope (this reference) in which the handler function is executed. If omitted,\n defaults to the object which fired the event.
  \n\n
- delay : Number
  The number of milliseconds to delay the invocation of the handler after the event fires.
  \n\n
- single : Boolean
  True to add a handler to handle just the next firing of the event, and then remove itself.
  \n\n
- buffer : Number
  Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed\n by the specified number of milliseconds. If the event fires again within that time,\n the original handler is not invoked, but the new handler is scheduled in its place.
  \n\n
- target : Ext.util.Observable
  Only call the handler if the event was fired on the target Observable, not if the event\n was bubbled up from a child Observable.
  \n\n
- element : String
  This option is only valid for listeners bound to Components.\n The name of a Component property which references an element to add a listener to.
  \n\n\n\n\n
  This option is useful during Component construction to add DOM event listeners to elements of\n Components which will exist only after the Component is rendered.\n For example, to add a click listener to a Panel's body:
  \n\n\n\n\n
```
  new Ext.panel.Panel({\n      title: 'The title',\n      listeners: {\n          click: this.handlePanelClick,\n          element: 'body'\n      }\n  });\n
```
  \n\n
- 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.
  \n\n
  Defaults to: false
- priority : Number (optional)
  An optional numeric priority that determines the order in which event handlers\n are run. Event handlers with no priority will be run as if they had a priority\n of 0. Handlers with a higher priority will be prioritized to run sooner than\n those with a lower priority. Negative numbers can be used to set a priority\n lower than the default. Internally, the framework uses a range of 1000 or\n greater, and -1000 or lesser for handers that are intended to run before or\n after all others, so it is recommended to stay within the range of -999 to 999\n when setting the priority of event handlers in application-level code.
  \n\n\n\n\n
  Combining Options
  \n\n\n\n\n
  Using the options argument, it is possible to combine different types of listeners:
  \n\n\n\n\n
  A delayed, one-time listener.
  \n\n\n\n\n
```
myPanel.on('hide', this.handleClick, this, {\n    single: true,\n    delay: 100\n});\n
```
  \n\n

Returns

Only when the destroyable option is specified.

\n\n\n\n\n

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

\n\n\n\n\n

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

\n\n\n\n\n

This method has been deprecated

as of 4.1. Use callParent instead.

\n\n

Parameters

args : Array/Arguments
The arguments, either an array or the arguments object\nfrom the current method, for example: this.callOverridden(arguments)
\n

Returns

Object
Returns the result of calling the overridden method
\n

callParent( args ) : Objectprotected

Call the \"parent\" method of the current method. ...

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

\n\n

 Ext.define('My.Base', {\n     constructor: function (x) {\n         this.x = x;\n     },\n\n     statics: {\n         method: function (x) {\n             return x;\n         }\n     }\n });\n\n Ext.define('My.Derived', {\n     extend: 'My.Base',\n\n     constructor: function () {\n         this.callParent([21]);\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // alerts 21\n

\n\n

This can be used with an override as follows:

\n\n

 Ext.define('My.DerivedOverride', {\n     override: 'My.Derived',\n\n     constructor: function (x) {\n         this.callParent([x*2]); // calls original My.Derived constructor\n     }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x);  // now alerts 42\n

\n\n

This also works with static methods.

\n\n

 Ext.define('My.Derived2', {\n     extend: 'My.Base',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Base.method\n         }\n     }\n });\n\n alert(My.Base.method(10);     // alerts 10\n alert(My.Derived2.method(10); // alerts 20\n

\n\n

Lastly, it also works with overridden static methods.

\n\n

 Ext.define('My.Derived2Override', {\n     override: 'My.Derived2',\n\n     statics: {\n         method: function (x) {\n             return this.callParent([x*2]); // calls My.Derived2.method\n         }\n     }\n });\n\n alert(My.Derived2.method(10); // now alerts 40\n

\n\n

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

Parameters

args : Array/Arguments
The arguments, either an array or the arguments object\nfrom the current method, for example: this.callParent(arguments)
\n

Returns

Object
Returns the result of calling the parent method
\n

callSuper( args ) : Objectprotected

This method is used by an override to call the superclass method but bypass any\noverridden method. ...

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

\n\n

Consider:

\n\n

 Ext.define('Ext.some.Class', {\n     method: function () {\n         console.log('Good');\n     }\n });\n\n Ext.define('Ext.some.DerivedClass', {\n     method: function () {\n         console.log('Bad');\n\n         // ... logic but with a bug ...\n\n         this.callParent();\n     }\n });\n

\n\n

To patch the bug in DerivedClass.method, the typical solution is to create an\noverride:

\n\n

 Ext.define('App.paches.DerivedClass', {\n     override: 'Ext.some.DerivedClass',\n\n     method: function () {\n         console.log('Fixed');\n\n         // ... logic but with bug fixed ...\n\n         this.callSuper();\n     }\n });\n

\n\n

The patch method cannot use callParent to call the superclass method since\nthat would call the overridden method containing the bug. In other words, the\nabove patch would only produce \"Fixed\" then \"Good\" in the console log, whereas,\nusing callParent would produce \"Fixed\" then \"Bad\" then \"Good\".

Parameters

args : Array/Arguments
The arguments, either an array or the arguments object\nfrom the current method, for example: this.callSuper(arguments)
\n

Returns

Object
Returns the result of calling the superclass method

control( selectors, [listeners] )

Adds listeners to components selected via Ext.ComponentQuery. ...

Adds listeners to components selected via Ext.ComponentQuery. Accepts an\nobject containing component paths mapped to a hash of listener functions.

\n\n

In the following example the updateUser function is mapped to to the click\nevent on a button component, which is a child of the useredit component.

\n\n

 Ext.define('AM.controller.Users', {\n     init: function() {\n         this.control({\n             'useredit button[action=save]': {\n                 click: this.updateUser\n             }\n         });\n     },\n\n     updateUser: function(button) {\n         console.log('clicked the Save button');\n     }\n });\n

\n\n

Or alternatively one call control with two arguments:

\n\n

 this.control('useredit button[action=save]', {\n     click: this.updateUser\n });\n

\n\n

See Ext.ComponentQuery for more information on component selectors.

Parameters

selectors : String/Object
If a String, the second argument is used as the\nlisteners, otherwise an object of selectors -> listeners is assumed

enableBubble( eventNames )

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if\npresent. ...

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

\n\n

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

\n\n

Example:

\n\n

Ext.define('Ext.overrides.form.field.Base', {\n    override: 'Ext.form.field.Base',\n\n    //  Add functionality to Field's initComponent to enable the change event to bubble\n    initComponent: function () {\n        this.callParent();\n        this.enableBubble('change');\n    }\n});\n\nvar myForm = Ext.create('Ext.form.Panel', {\n    title: 'User Details',\n    items: [{\n        ...\n    }],\n    listeners: {\n        change: function() {\n            // Title goes red if form has been modified.\n            myForm.header.setStyle('color', 'red');\n        }\n    }\n});\n

\n

listen( to )

Adds listeners to different event sources (also called \"event domains\"). ...

Adds listeners to different event sources (also called \"event domains\"). The\nprimary event domain is that of components, but there are also other event domains:\nGlobal domain that intercepts events fired from\nExt.globalEvents Observable instance, Controller\ndomain can be used to listen to events fired by other Controllers,\nStore domain gives access to Store events, and\nDirect domain can be used with Ext.Direct Providers\nto listen to their events.

\n\n

To listen to \"bar\" events fired by a controller with id=\"foo\":

\n\n

 Ext.define('AM.controller.Users', {\n     init: function() {\n         this.listen({\n             controller: {\n                 '#foo': {\n                    bar: this.onFooBar\n                 }\n             }\n         });\n     },\n     ...\n });\n

\n\n

To listen to \"bar\" events fired by any controller, and \"baz\" events\nfired by Store with storeId=\"baz\":

\n\n

 Ext.define('AM.controller.Users', {\n     init: function() {\n         this.listen({\n             controller: {\n                 '*': {\n                    bar: this.onAnyControllerBar\n                 }\n             },\n             store: {\n                 '#baz': {\n                     baz: this.onStoreBaz\n                 }\n             }\n         });\n     },\n     ...\n });\n

\n\n

To listen to \"idle\" events fired by Ext.globalEvents when other event\nprocessing is complete and Ext JS is about to return control to the browser:

\n\n

 Ext.define('AM.controller.Users', {\n     init: function() {\n         this.listen({\n             global: {               // Global events are always fired\n                 idle: this.onIdle   // from the same object, so there\n             }                       // are no selectors\n         });\n     }\n });\n

\n\n

As this relates to components, the following example:

\n\n

 Ext.define('AM.controller.Users', {\n     init: function() {\n         this.listen({\n             component: {\n                 'useredit button[action=save]': {\n                    click: this.updateUser\n                 }\n             }\n         });\n     },\n     ...\n });\n

\n\n

Is equivalent to:

\n\n

 Ext.define('AM.controller.Users', {\n     init: function() {\n         this.control({\n             'useredit button[action=save]': {\n                click: this.updateUser\n             }\n         });\n     },\n     ...\n });\n

\n\n

Of course, these can all be combined in a single call and used instead of\ncontrol, like so:

\n\n

 Ext.define('AM.controller.Users', {\n     init: function() {\n         this.listen({\n             global: {\n                 idle: this.onIdle\n             },\n             controller: {\n                 '*': {\n                    foobar: this.onAnyFooBar\n                 },\n                 '#foo': {\n                    bar: this.onFooBar\n                 }\n             },\n             component: {\n                 'useredit button[action=save]': {\n                    click: this.updateUser\n                 }\n             },\n             store: {\n                 '#qux': {\n                     load: this.onQuxLoad\n                 }\n             }\n         });\n     },\n     ...\n });\n

Parameters

item : Ext.util.Observable/Ext.Element
The item to which to add a listener/listeners.
\n\n
ename : Object/String
The event name, or an object containing event name properties.
\n\n
fn : Function (optional)

\n\n

Returns

Only when the destroyable option is specified.

\n\n\n\n\n

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

\n\n\n\n\n

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

\n\n\n\n\n

And when those listeners need to be removed:

\n\n\n\n\n

Ext.destroy(this.btnListeners);\n

\n\n\n\n\n

this.btnListeners.destroy();\n

\n\n

mun( item, ename, [fn], [scope] )

Shorthand for removeManagedListener. ...

Shorthand for removeManagedListener.

\n\n

Removes listeners that were added by the mon method.

Parameters

item : Ext.util.Observable/Ext.Element
The item from which to remove a listener/listeners.
\n\n
ename : Object/String

\n\n
fn : Function (optional)
If the ename parameter was an event name, this is the handler function.
\n\n
scope : Object (optional)
If the ename parameter was an event name, this is the scope (this reference)\nin which the handler function is executed.
\n\n

on( eventName, [fn], [scope], [options] ) : Object

Shorthand for addListener. ...

Shorthand for addListener.

\n\n

Appends an event handler to this object. For example:

\n\n

myGridPanel.on(\"mouseover\", this.onMouseOver, this);\n

\n\n

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

\n\n

myGridPanel.on({\n    cellClick: this.onCellClick,\n    mouseover: this.onMouseOver,\n    mouseout: this.onMouseOut,\n    scope: this // Important. Ensure \"this\" is correct during handler execution\n});\n

\n\n

One can also specify options for each event handler separately:

\n\n

myGridPanel.on({\n    cellClick: {fn: this.onCellClick, scope: this, single: true},\n    mouseover: {fn: panel.onMouseOver, scope: panel}\n});\n

\n\n

Names of methods in a specified scope may also be used. Note that\nscope MUST be specified to use this option:

\n\n

myGridPanel.on({\n    cellClick: {fn: 'onCellClick', scope: this, single: true},\n    mouseover: {fn: 'onMouseOver', scope: panel}\n});\n

Parameters

eventName : String/Object
The name of the event to listen for.\nMay also be an object who's property names are event names.
\n\n
fn : Function (optional)
The method the event invokes, or if scope is specified, the name* of the method within\nthe specified scope. Will be called with arguments\ngiven to fireEvent plus the options parameter described below.
\n\n
scope : Object (optional)
The scope (this reference) in which the handler function is\nexecuted. If omitted, defaults to the object which fired the event.
\n\n
options : Object (optional)
An object containing handler configuration.
\n\n\n\n\n
Note: Unlike in ExtJS 3.x, the options object will also be passed as the last\nargument to every event handler.
\n\n\n\n\n
This object may contain any of the following properties:
\n\n
- scope : Object
  The scope (this reference) in which the handler function is executed. If omitted,\n defaults to the object which fired the event.
  \n\n
- delay : Number
  The number of milliseconds to delay the invocation of the handler after the event fires.
  \n\n
- single : Boolean
  True to add a handler to handle just the next firing of the event, and then remove itself.
  \n\n
- buffer : Number
  Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed\n by the specified number of milliseconds. If the event fires again within that time,\n the original handler is not invoked, but the new handler is scheduled in its place.
  \n\n
- target : Ext.util.Observable
  Only call the handler if the event was fired on the target Observable, not if the event\n was bubbled up from a child Observable.
  \n\n
- element : String
  This option is only valid for listeners bound to Components.\n The name of a Component property which references an element to add a listener to.
  \n\n\n\n\n
  This option is useful during Component construction to add DOM event listeners to elements of\n Components which will exist only after the Component is rendered.\n For example, to add a click listener to a Panel's body:
  \n\n\n\n\n
```
  new Ext.panel.Panel({\n      title: 'The title',\n      listeners: {\n          click: this.handlePanelClick,\n          element: 'body'\n      }\n  });\n
```
  \n\n
- 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.
  \n\n
  Defaults to: false
- priority : Number (optional)
  An optional numeric priority that determines the order in which event handlers\n are run. Event handlers with no priority will be run as if they had a priority\n of 0. Handlers with a higher priority will be prioritized to run sooner than\n those with a lower priority. Negative numbers can be used to set a priority\n lower than the default. Internally, the framework uses a range of 1000 or\n greater, and -1000 or lesser for handers that are intended to run before or\n after all others, so it is recommended to stay within the range of -999 to 999\n when setting the priority of event handlers in application-level code.
  \n\n\n\n\n
  Combining Options
  \n\n\n\n\n
  Using the options argument, it is possible to combine different types of listeners:
  \n\n\n\n\n
  A delayed, one-time listener.
  \n\n\n\n\n
```
myPanel.on('hide', this.handleClick, this, {\n    single: true,\n    delay: 100\n});\n
```
  \n\n

Returns

Only when the destroyable option is specified.

\n\n\n\n\n

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

\n\n\n\n\n

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

\n\n\n\n\n

And when those listeners need to be removed:

\n\n\n\n\n

Ext.destroy(this.btnListeners);\n

\n\n\n\n\n

this.btnListeners.destroy();\n

relayEvents( origin, events, [prefix] ) : Object

Relays selected events from the specified Observable as if the events were fired by this. ...

Relays selected events from the specified Observable as if the events were fired by this.

\n\n

For example if you are extending Grid, you might decide to forward some events from store.\nSo you can do this inside your initComponent:

\n\n

this.relayEvents(this.getStore(), ['load']);\n

\n\n

The grid instance will then have an observable 'load' event which will be passed the\nparameters of the store's load event and any function fired with the grid's load event\nwould have access to the grid using the this keyword.

Parameters

origin : Object
The Observable whose events this object is to relay.
\n
events : String[]
Array of event names to relay.
\n
prefix : String (optional)
A common prefix to prepend to the event names. For example:
\n\n
```
this.relayEvents(this.getStore(), ['load', 'clear'], 'store');\n
```
\n\n
Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.
\n

Returns

Object
A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:
\n\n
```
this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');\n
```
\n\n
Can be undone by calling
\n\n
```
Ext.destroy(this.storeRelayers);\n
```
\n\n
or
\n\n
```
this.store.relayers.destroy();\n
```

Ext.define('My.Cat', {\n    constructor: function() {\n        alert(\"I'm a cat!\");\n    }\n});\n\nMy.Cat.override({\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callParent(arguments);\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n                          // alerts \"I'm a cat!\"\n                          // alerts \"Meeeeoooowwww\"\n

\n\n

As of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:

\n\n

Ext.define('My.CatOverride', {\n    override: 'My.Cat',\n    constructor: function() {\n        alert(\"I'm going to be a cat!\");\n\n        this.callParent(arguments);\n\n        alert(\"Meeeeoooowwww\");\n    }\n});\n

\n\n

The above accomplishes the same result but can be managed by the Ext.Loader\nwhich can properly order the override and its target class and the build process\ncan determine whether the override is needed based on the required state of the\ntarget class (My.Cat).

This method has been deprecated since 4.1.0

Use Ext.define instead

\n\n

Parameters

members : Object
The properties to add to this class. This should be\nspecified as an object literal containing one or more properties.
\n

Returns

Ext.Base
