Tracks what records are currently selected in a databound component.
\n\nThis is an abstract class and is not meant to be directly used. Databound UI widgets such as\nGrid and Tree should subclass Ext.selection.Model\nand provide a way to binding to the component.
\n\nThe abstract methods onSelectChange
and onLastFocusChanged
should be implemented in these\nsubclasses to update the UI widget.
Allow users to deselect a record in a DataView, List or Grid.\nOnly applicable when the mode is 'SINGLE'.
\nA config object containing one or more event handlers to be added to this object during initialization. This\nshould be a valid listeners config object as specified in the addListener example for attaching multiple\nhandlers at once.
\n\nDOM events from Ext JS Components
\n\nWhile 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:
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
\nMode of selection. Valid values are:
\n\nRemove records from the selection when they are removed from the store.
\n\nImportant: When using paging or a sparsely populated (buffered) Store,\nrecords which are cached in the Store's data collection may be removed from the Store when pages change,\nor when rows are scrolled out of view. For this reason pruneRemoved
should be set to false
when using a buffered Store.
Also, when previously pruned pages are returned to the cache, the records objects in the page will be\nnew instances, and will not match the instances in the selection model's collection. For this reason,\nyou MUST ensure that the Model definition's idProperty references a unique\nkey because in this situation, records in the Store have their IDs compared to records in the SelectionModel\nin order to re-select a record which is scrolled back into view.
\nDefaults to: true
true
to toggle the selection state of an item when clicked.\nOnly applicable when the mode is 'SINGLE'.\nOnly applicable when the allowDeselect is 'true'.
Defaults to: true
Initial suspended call count. Incremented when suspendEvents is called, decremented when resumeEvents is called.
\nDefaults to: 0
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\nThe 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
\ntrue
in this class to identify an object as an instantiated Observable, or subclass thereof.
Defaults to: true
A MixedCollection that maintains all of the currently selected records.
\nGet the reference to the current class from which this object was instantiated. Unlike statics,\nthis.self
is scope-dependent and it's meant to be used for dynamic inheritance. See statics\nfor a detailed comparison
Ext.define('My.Cat', {\n statics: {\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n alert(this.self.speciesName); // dependent on 'this'\n },\n\n clone: function() {\n return new this.self();\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat'\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\n
\nAdds the specified events to the list of events which this Observable may fire.
\nEither an object with event names as properties with\na value of true
. For example:
this.addEvents({\n storeloaded: true,\n storecleared: true\n});\n
\n\nOr any number of event names as separate parameters. For example:
\n\nthis.addEvents('storeloaded', 'storecleared');\n
\nAppends an event handler to this object. For example:
\n\nmyGridPanel.on(\"mouseover\", this.onMouseOver, this);\n
\n\nThe method also allows for a single argument to be passed which is a config object\ncontaining properties which specify multiple events. For example:
\n\nmyGridPanel.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\nOne can also specify options for each event handler separately:
\n\nmyGridPanel.on({\n cellClick: {fn: this.onCellClick, scope: this, single: true},\n mouseover: {fn: panel.onMouseOver, scope: panel}\n});\n
\n\nNames of methods in a specified scope may also be used. Note that\nscope
MUST be specified to use this option:
myGridPanel.on({\n cellClick: {fn: 'onCellClick', scope: this, single: true},\n mouseover: {fn: 'onMouseOver', scope: panel}\n});\n
\nThe name of the event to listen for.\nMay also be an object who's property names are event names.
\n\nThe 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.
The scope (this
reference) in which the handler function is\nexecuted. If omitted, defaults to the object which fired the event.
An object containing handler configuration.
\n\n\n\n\nNote: Unlike in ExtJS 3.x, the options object will also be passed as the last\nargument to every event handler.
\n\n\n\n\nThis object may contain any of the following properties:
\n\nThe scope (this
reference) in which the handler function is executed. If omitted,\n defaults to the object which fired the event.
The number of milliseconds to delay the invocation of the handler after the event fires.
\n\nTrue to add a handler to handle just the next firing of the event, and then remove itself.
\n\nCauses 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\nOnly 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\nThis 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\nThis 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\nWhen specified as true
, the function returns A Destroyable
object. An object which implements the destroy
method which removes all listeners added in this call.
Defaults to: false
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\nCombining Options
\n\n\n\n\nUsing the options argument, it is possible to combine different types of listeners:
\n\n\n\n\nA delayed, one-time listener.
\n\n\n\n\nmyPanel.on('hide', this.handleClick, this, {\n single: true,\n delay: 100\n});\n
\n\nOnly 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({\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\nAnd when those listeners need to be removed:
\n\n\n\n\nExt.destroy(this.btnListeners);\n
\n\n\n\n\nor
\n\n\n\n\nthis.btnListeners.destroy();\n
\n\nAdds listeners to any Observable object (or Ext.Element) which are automatically removed when this Component is\ndestroyed.
\nThe item to which to add a listener/listeners.
\n\nThe event name, or an object containing event name properties.
\n\nIf the ename
parameter was an event name, this is the handler function.
If the ename
parameter was an event name, this is the scope (this
reference)\nin which the handler function is executed.
If the ename
parameter was an event name, this is the\naddListener options.
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({\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\nAnd when those listeners need to be removed:
\n\n\n\n\nExt.destroy(this.btnListeners);\n
\n\n\n\n\nor
\n\n\n\n\nthis.btnListeners.destroy();\n
\n\nbinds the store to the selModel.
\n\nBinds a store to this instance.
\nThe store to bind or ID of the store.\nWhen no store given (or when null
or undefined
passed), unbinds the existing store.
Overrides: Ext.util.Bindable.bindStore
Binds listeners for this component to the store. By default it will add\nanything bound by the getStoreListeners method, however it can be overridden\nin a subclass to provide any more complicated handling.
\nThe store to bind to
\nCall the original method that was previously overridden with override
\n\nExt.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.callOverridden();\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 This method has been deprecated
\nas of 4.1. Use callParent instead.
\n\nThe arguments, either an array or the arguments
object\nfrom the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
\nCall 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\nThis 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\nThis 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\nLastly, 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\nTo 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.
\nThe arguments, either an array or the arguments
object\nfrom the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
\nThis 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\nConsider:
\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\nTo patch the bug in DerivedClass.method
, the typical solution is to create an\noverride:
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\nThe 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\".
The arguments, either an array or the arguments
object\nfrom the current method, for example: this.callSuper(arguments)
Returns the result of calling the superclass method
\nRemoves all listeners for this object including the managed listeners
\nA fast reset of the selections without firing events, updating the ui, etc.\nFor private usage only.
\nDeselects a record instance by record instance or index.
\nAn array of records or an index
\nTrue to not fire a deselect event
\nDefaults to: false
Deselects all records in the view.
\nTrue to suppress any deselect events
\nCalled by subclasses to deselect records upon detection of deletion from the store
\nDeselects a range of rows if the selection model is not locked.
\nThe record or index of the first row in the range
\nThe record or index of the last row in the range
\nEnables 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.
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\nExample:
\n\nExt.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\nAdds listeners to any Observable object (or Ext.Element) which are automatically removed when this Component is\ndestroyed.
\nThe item to which to add a listener/listeners.
\n\nThe event name, or an object containing event name properties.
\n\nIf the ename

Shorthand for addListener.
\n\nAppends an event handler to this object. For example:
\n\nmyGridPanel.on(\"mouseover\", this.onMouseOver, this);\n
\n\nThe method also allows for a single argument to be passed which is a config object\ncontaining properties which specify multiple events. For example:
\n\nmyGridPanel.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\nOne can also specify options for each event handler separately:
\n\nmyGridPanel.on({\n cellClick: {fn: this.onCellClick, scope: this, single: true},\n mouseover: {fn: panel.onMouseOver, scope: panel}\n});\n
\n\nNames of methods in a specified scope may also be used. Note that\nscope
MUST be specified to use this option:
myGridPanel.on({\n cellClick: {fn: 'onCellClick', scope: this, single: true},\n mouseover: {fn: 'onMouseOver', scope: panel}\n});\n
\nThe name of the event to listen for.\nMay also be an object who's property names are event names.

. Will be called with arguments\ngiven to fireEvent plus the options
parameter described below.
The scope (this
reference) in which the handler function is\nexecuted. If omitted, defaults to the object which fired the event.
An object containing handler configuration.
\n\n\n\n\nNote: Unlike in ExtJS 3.x, the options object will also be passed as the last\nargument to every event handler.

The number of milliseconds to delay the invocation of the handler after the event fires.
\n\nTrue to add a handler to handle just the next firing of the event, and then remove itself.
\n\nCauses 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\nOnly 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\nThis 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\nThis 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\nWhen specified as true
, the function returns A Destroyable
object. An object which implements the destroy
method which removes all listeners added in this call.
Defaults to: false
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\nCombining Options
\n\n\n\n\nUsing the options argument, it is possible to combine different types of listeners:
\n\n\n\n\nA delayed, one-time listener.
\n\n\n\n\nmyPanel.on('hide', this.handleClick, this, {\n single: true,\n delay: 100\n});\n
\n\nOnly when the destroyable

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

\n\nTemplate method, it is called when a new store is bound\nto the current instance.
\nThe store being bound
\nTrue if this store is being bound as initialization of the instance.
\nwhen a store is cleared remove all selections\n(if there were any)
\nTemplate method, it is called when an existing store is unbound\nfrom the current instance.
\nThe store being unbound
\nTrue if this store is being bound as initialization of the instance.
\nCalled when the contents of the node are updated, perform any processing here.
\nPrepares a given class for observable instances. This method is called when a\nclass derives from this class or uses this class as a mixin.
\nThe class constructor to prepare.
\nRelays 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.\nSo you can do this inside your initComponent:
\n\nthis.relayEvents(this.getStore(), ['load']);\n
\n\nThe 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.
The Observable whose events this object is to relay.
\nArray of event names to relay.
\nA common prefix to prepend to the event names. For example:
\n\nthis.relayEvents(this.getStore(), ['load', 'clear'], 'store');\n
\n\nNow the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.
\nA 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');\n
\n\nCan be undone by calling
\n\nExt.destroy(this.storeRelayers);\n
\n\nor
\n\nthis.store.relayers.destroy();\n
\nRemoves an event handler.
\nThe type of event the handler was associated with.
\n\nThe handler to remove. This must be a reference to the function passed into the\naddListener call.
\n\nThe scope originally specified for the handler. It must be the same as the\nscope argument specified in the original call to addListener or the listener will not be removed.
\n\nRemoves listeners that were added by the mon method.
\nThe item from which to remove a listener/listeners.
\n\nThe event name, or an object containing event name properties.
\n\nIf the ename
parameter was an event name, this is the handler function.
If the ename
parameter was an event name, this is the scope (this
reference)\nin which the handler function is executed.
Resumes firing of the named event(s).
\n\nAfter calling this method to resume events, the events will fire when requested to fire.
\n\nNote that if the suspendEvent method is called multiple times for a certain event,\nthis converse method will have to be called the same number of times for it to resume firing.
\nMultiple event names to resume.
\nResumes firing events (see suspendEvents).
\n\nIf events were suspended using the queueSuspended
parameter, then all events fired\nduring event suspension will be sent to any listeners now.
Selects a record instance by record instance or index.
\nAn array of records or an index
\nTrue to retain existing selections
\nDefaults to: false
True to not fire a select event
\nDefaults to: false
Selects all records in the view.
\nTrue to suppress any select events
\nSelects a range of rows if the selection model is not locked.\nAll rows in between startRow and endRow are also selected.
\nThe record or index of the first row in the range
\nThe record or index of the last row in the range
\nTrue to retain existing selections
\nSets a record as the last focused record. This does NOT mean\nthat the record has been selected.
\nLocks the current selection and disables any changes from happening to the selection.
\nTrue to lock, false to unlock.
\nGet the reference to the class from which this object was instantiated. Note that unlike self,\nthis.statics()
is scope-independent and it always returns the class from which it was called, regardless of what\nthis
points to during run-time
Ext.define('My.Cat', {\n statics: {\n totalCreated: 0,\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n var statics = this.statics();\n\n alert(statics.speciesName); // always equals to 'Cat' no matter what 'this' refers to\n // equivalent to: My.Cat.speciesName\n\n alert(this.self.speciesName); // dependent on 'this'\n\n statics.totalCreated++;\n },\n\n clone: function() {\n var cloned = new this.self; // dependent on 'this'\n\n cloned.groupName = this.statics().speciesName; // equivalent to: My.Cat.speciesName\n\n return cloned;\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n },\n\n constructor: function() {\n this.callParent();\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat', then alerts 'Cat'\n\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Cat', then alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\nalert(clone.groupName); // alerts 'Cat'\n\nalert(My.Cat.totalCreated); // alerts 3\n
\nWe need this special check because we could have a model\nwithout an idProperty. getById() is fast, so we use that\nif possible, otherwise we need to check the internalId
\nSuspends firing of the named event(s).
\n\nAfter calling this method to suspend events, the events will no longer fire when requested to fire.
\n\nNote that if this is called multiple times for a certain event, the converse method\nresumeEvent will have to be called the same number of times for it to resume firing.
\nMultiple event names to suspend.
\nSuspends the firing of all events. (see resumeEvents)
\nPass as true to queue up suspended events to be fired\nafter the resumeEvents call instead of discarding all suspended events.
\nShorthand for removeListener.
\n\nRemoves an event handler.
\nThe type of event the handler was associated with.
\n\nThe handler to remove. This must be a reference to the function passed into the\naddListener call.
\n\nThe scope originally specified for the handler. It must be the same as the\nscope argument specified in the original call to addListener or the listener will not be removed.
\n\nUnbinds listeners from this component to the store. By default it will remove\nanything bound by the bindStoreListeners method, however it can be overridden\nin a subclass to provide any more complicated handling.
\nThe store to unbind from
\nAdd methods / properties to the prototype of this class.
\n\nExt.define('My.awesome.Cat', {\n constructor: function() {\n ...\n }\n});\n\n My.awesome.Cat.addMembers({\n meow: function() {\n alert('Meowww...');\n }\n });\n\n var kitty = new My.awesome.Cat;\n kitty.meow();\n
\nAdd / override static properties of this class.
\n\nExt.define('My.cool.Class', {\n ...\n});\n\nMy.cool.Class.addStatics({\n someProperty: 'someValue', // My.cool.Class.someProperty = 'someValue'\n method1: function() { ... }, // My.cool.Class.method1 = function() { ... };\n method2: function() { ... } // My.cool.Class.method2 = function() { ... };\n});\n
\nthis
\nBorrow another class' members to the prototype of this class.
\n\nExt.define('Bank', {\n money: '$$$',\n printMoney: function() {\n alert('$$$$$$$');\n }\n});\n\nExt.define('Thief', {\n ...\n});\n\nThief.borrow(Bank, ['money', 'printMoney']);\n\nvar steve = new Thief();\n\nalert(steve.money); // alerts '$$$'\nsteve.printMoney(); // alerts '$$$$$$$'\n
\nThe class to borrow members from
\nThe names of the members to borrow
\nthis
\nCreate a new instance of this Class.
\n\nExt.define('My.cool.Class', {\n ...\n});\n\nMy.cool.Class.create({\n someConfig: true\n});\n
\n\nAll parameters are passed to the constructor of the class.
\nthe created instance.
\nCreate aliases for existing prototype methods. Example:
\n\nExt.define('My.cool.Class', {\n method1: function() { ... },\n method2: function() { ... }\n});\n\nvar test = new My.cool.Class();\n\nMy.cool.Class.createAlias({\n method3: 'method1',\n method4: 'method2'\n});\n\ntest.method3(); // test.method1()\n\nMy.cool.Class.createAlias('method5', 'method3');\n\ntest.method5(); // test.method3() -> test.method1()\n
\nThe new method name, or an object to set multiple aliases. See\nflexSetter
\nThe original method name
\nGet the current class' name in string format.
\n\nExt.define('My.cool.Class', {\n constructor: function() {\n alert(this.self.getName()); // alerts 'My.cool.Class'\n }\n});\n\nMy.cool.Class.getName(); // 'My.cool.Class'\n
\nclassName
\nAdds members to class.
\nThis method has been deprecated since 4.1
\nUse addMembers instead.
\n\nOverride members of this class. Overridden methods can be invoked via\ncallParent.
\n\nExt.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\nAs of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:
\n\nExt.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\nThe 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).
\nThis method has been deprecated since 4.1.0
\nUse Ext.define instead
\n\nThe properties to add to this class. This should be\nspecified as an object literal containing one or more properties.
