Terms, Icons, and Labels

Many classes have shortcut names used when creating (instantiating) a class with a configuration object. The shortcut name is referred to as an alias (or xtype if the class extends Ext.Component). The alias/xtype is listed next to the class name of applicable classes for quick reference.

Access Levels

Framework classes or their members may be specified as private or protected. Else, the class / member is public. Public, protected, and private are access descriptors used to convey how and when the class or class member should be used.

Member Types

Member Syntax

Below is an example class member that we can disect to show the syntax of a class member (the lookupComponent method as viewed from the Ext.button.Button class in this case).

lookupComponent ( item ) : Ext.Component
protected

Called when a raw config object is added to this container either during initialization of the items config, or when new items are added), or {@link #insert inserted.

This method converts the passed object into an instanced child component.

This may be overridden in subclasses when special processing needs to be applied to child creation.

Parameters

item :  Object

The config object being added.

Returns
Ext.Component

The component to be added.

Let's look at each part of the member row:

Member Flags

The API documentation uses a number of flags to further commnicate the class member's function and intent. The label may be represented by a text label, an abbreviation, or an icon.

Class Icons

- Indicates a framework class

- A singleton framework class. *See the singleton flag for more information

- A component-type framework class (any class within the Ext JS framework that extends Ext.Component)

- Indicates that the class, member, or guide is new in the currently viewed version

Member Icons

- Indicates a class member of type config

- Indicates a class member of type property

- Indicates a class member of type method

- Indicates a class member of type event

- Indicates a class member of type theme variable

- Indicates a class member of type theme mixin

- Indicates that the class, member, or guide is new in the currently viewed version

Class Member Quick-Nav Menu

Just below the class name on an API doc page is a row of buttons corresponding to the types of members owned by the current class. Each button shows a count of members by type (this count is updated as filters are applied). Clicking the button will navigate you to that member section. Hovering over the member-type button will reveal a popup menu of all members of that type for quick navigation.

Getter and Setter Methods

Getting and setter methods that correlate to a class config option will show up in the methods section as well as in the configs section of both the API doc and the member-type menus just beneath the config they work with. The getter and setter method documentation will be found in the config row for easy reference.

History Bar

Your page history is kept in localstorage and displayed (using the available real estate) just below the top title bar. By default, the only search results shown are the pages matching the product / version you're currently viewing. You can expand what is displayed by clicking on the button on the right-hand side of the history bar and choosing the "All" radio option. This will show all recent pages in the history bar for all products / versions.

Within the history config menu you will also see a listing of your recent page visits. The results are filtered by the "Current Product / Version" and "All" radio options. Clicking on the button will clear the history bar as well as the history kept in local storage.

If "All" is selected in the history config menu the checkbox option for "Show product details in the history bar" will be enabled. When checked, the product/version for each historic page will show alongside the page name in the history bar. Hovering the cursor over the page names in the history bar will also show the product/version as a tooltip.

Search and Filters

Both API docs and guides can be searched for using the search field at the top of the page.

On API doc pages there is also a filter input field that filters the member rows using the filter string. In addition to filtering by string you can filter the class members by access level, inheritance, and read only. This is done using the checkboxes at the top of the page.

The checkbox at the bottom of the API class navigation tree filters the class list to include or exclude private classes.

Clicking on an empty search field will show your last 10 searches for quick navigation.

API Doc Class Metadata

Each API doc page (with the exception of Javascript primitives pages) has a menu view of metadata relating to that class. This metadata view will have one or more of the following:

Expanding and Collapsing Examples and Class Members

Runnable examples (Fiddles) are expanded on a page by default. You can collapse and expand example code blocks individually using the arrow on the top-left of the code block. You can also toggle the collapse state of all examples using the toggle button on the top-right of the page. The toggle-all state will be remembered between page loads.

Class members are collapsed on a page by default. You can expand and collapse members using the arrow icon on the left of the member row or globally using the expand / collapse all toggle button top-right.

Desktop -vs- Mobile View

Viewing the docs on narrower screens or browsers will result in a view optimized for a smaller form factor. The primary differences between the desktop and "mobile" view are:

Viewing the Class Source

The class source can be viewed by clicking on the class name at the top of an API doc page. The source for class members can be viewed by clicking on the "view source" link on the right-hand side of the member row.

Ext.Base
Ext.dd.DragDropManager

Requires

Ext.util.Region

Summary

DragDropManager is a singleton that tracks the element interaction for all DragDrop items in the window. Generally, you will not call this class directly, but it does have helper methods that could be useful in your DragDrop implementations.

properties

Instance Properties

$className
private pri

Defaults to:

'Ext.Base'

$configPrefixed : Boolean
private pri

The value true causes config values to be stored on instances using a property name prefixed with an underscore ("_") character. A value of false stores config values as properties using their exact name (no prefix).

Defaults to:

true

Available since: 5.0.0

$configStrict : Boolean
private pri

The value true instructs the initConfig method to only honor values for properties declared in the config block of a class. When false, properties that are not declared in a config block will be placed on the instance.

Defaults to:

true

Available since: 5.0.0

clearPropertiesOnDestroy : Boolean / "async"
protected pro

Setting this property to false will prevent nulling object references on a Class instance after destruction. Setting this to "async" will delay the clearing for approx 50ms.

Defaults to:

true

Available since: 6.2.0

clearPrototypeOnDestroy : Boolean
private pri

Setting this property to true will result in setting the object's prototype to null after the destruction sequence is fully completed. After that, most attempts at calling methods on the object instance will result in "method not defined" exception. This can be very helpful with tracking down otherwise hard to find bugs like runaway Ajax requests, timed functions not cleared on destruction, etc.

Note that this option can only work in browsers that support Object.setPrototypeOf method, and is only available in debugging mode.

Defaults to:

false

Available since: 6.2.0

clickPixelThresh : Number

The number of pixels that the mouse needs to move after the mousedown before the drag is initiated. Default=8; defaults to the same value used in the LongPress gesture so that drag cannot be initiated if there is a possible pending longpress

Defaults to:

8

clickTimeout : Object
private pri

Timeout used for the click time threshold

Defaults to:

null

deltaX : Number
private pri

the X distance between the cursor and the object being dragged

Defaults to:

0

deltaY : Number
private pri

the Y distance between the cursor and the object being dragged

Defaults to:

0

destroyed : Boolean
protected pro

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

Defaults to:

false

dragCls : String
readonly ro

Class to add to the dragged element of a DragDrop instance.

Defaults to:

Ext.baseCSSPrefix + 'dd-drag-current'

dragCurrent : Ext.dd.DragDrop
private pri

the DragDrop object that is currently being dragged

Defaults to:

null

dragOvers : Ext.dd.DragDrop[]
private pri

the DragDrop object(s) that are being hovered over

Defaults to:

{}

dragThreshMet : Boolean
private pri

Flag that indicates that either the drag pixel threshold or the mousdown time threshold has been met

Defaults to:

false

elementCache : Object
private pri

A cache of DOM elements

Defaults to:

{}

handleIds : String[]
private pri

Array of element ids defined as drag handles. Used to determine if the element that generated the mousedown event is actually the handle and not the html element itself.

Defaults to:

{}

ids : String[]
private pri

Two dimensional Array of registered DragDrop objects. The first dimension is the DragDrop item group, the second the DragDrop object.

Defaults to:

{}

initialized
private pri

Internal flag that is set to true when drag and drop has been intialized

Defaults to:

false

INTERSECT : Number

In intersect mode, drag and drop interaction is defined by the overlap of two or more drag and drop objects.

Defaults to:

1

isConfiguring : Boolean
readonly ro protected pro

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

Defaults to:

false

Available since: 5.0.0

isFirstInstance : Boolean
readonly ro protected pro

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

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

Defaults to:

true

locationCache : Object
private pri

Location cache that is set for all drag drop objects when a drag is initiated, cleared when the drag is finished.

Defaults to:

{}

locked
private pri

Defaults to:

true

locked

Unlock all drag and drop functionality

Defaults to:

false

mode : Number

The current drag and drop mode. Default: POINT

Defaults to:

0

notifyOccluded : Boolean

This config is only provided to provide old, usually unwanted drag/drop behaviour.

From ExtJS 4.1.0 onwards, when drop targets are contained in floating, absolutely positioned elements such as in Ext.window.Window, which may overlap each other, over and drop events are only delivered to the topmost drop target at the mouse position.

If all targets below that in zIndex order should also receive notifications, set notifyOccluded to true.

Defaults to:

false

POINT : Number

In point mode, drag and drop interaction is defined by the location of the cursor during the drag/drop

Defaults to:

0

Defaults to:

true

Deprecated since version 6.2.0

self : Ext.Class
protected pro

Get the reference to the current class from which this object was instantiated. Unlike Ext.Base#statics, this.self is scope-dependent and it's meant to be used for dynamic inheritance. See Ext.Base#statics for a detailed comparison

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

    constructor: function() {

        speciesName: 'Snow Leopard'         // My.SnowLeopard.speciesName = 'Snow Leopard'
    }
});

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

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

The X position of the mousedown event stored for later use when a drag threshold is met.

Defaults to:

0

startY : Number
private pri

The Y position of the mousedown event stored for later use when a drag threshold is met.

byZIndex ( d1, d2 )
private pri

Utility method to pass to Ext.Array#sort when sorting potential drop targets by z-index.

Parameters

d1 :  Object

d2 :  Object

callOverridden ( args ) : Object
deprecated dep protected pro

Call the original method that was previously overridden with Ext.Base#override

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callOverridden();

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callOverridden(arguments)

Returns

:Object

Returns the result of calling the overridden method

Deprecated since version 4.1.0

callParent ( args ) : Object
protected pro

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

 Ext.define('My.Base', {
     constructor: function (x) {
         this.x = x;
     },

     statics: {
         method: function (x) {
             return x;
         }
     }
 });

 Ext.define('My.Derived', {
     extend: 'My.Base',

     constructor: function () {
         this.callParent([21]);
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // alerts 21

This can be used with an override as follows:

 Ext.define('My.DerivedOverride', {
     override: 'My.Derived',

     constructor: function (x) {
         this.callParent([x*2]); // calls original My.Derived constructor
     }
 });

 var obj = new My.Derived();

 alert(obj.x);  // now alerts 42

This also works with static and private methods.

 Ext.define('My.Derived2', {
     extend: 'My.Base',

     // privates: {
     statics: {
         method: function (x) {
             return this.callParent([x*2]); // calls My.Base.method
         }
     }
 });

 alert(My.Base.method(10));     // alerts 10
 alert(My.Derived2.method(10)); // alerts 20

Lastly, it also works with overridden static methods.

 Ext.define('My.Derived2Override', {
     override: 'My.Derived2',

     // privates: {
     statics: {
         method: function (x) {
             return this.callParent([x*2]); // calls My.Derived2.method
         }
     }
 });

 alert(My.Derived2.method(10); // now alerts 40

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

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

Returns

:Object

Returns the result of calling the parent method

callSuper ( args ) : Object
protected pro

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

Consider:

 Ext.define('Ext.some.Class', {
     method: function () {
         console.log('Good');
     }
 });

 Ext.define('Ext.some.DerivedClass', {
     extend: 'Ext.some.Class',

     method: function () {
         console.log('Bad');

         // ... logic but with a bug ...

         this.callParent();
     }
 });

To patch the bug in Ext.some.DerivedClass.method, the typical solution is to create an override:

 Ext.define('App.patches.DerivedClass', {
     override: 'Ext.some.DerivedClass',

     method: function () {
         console.log('Fixed');

         // ... logic but with bug fixed ...

         this.callSuper();
     }
 });

The patch method cannot use method-callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

Parameters

args :  Array/Arguments

The arguments, either an array or the arguments object from the current method, for example: this.callSuper(arguments)

Returns

:Object

Returns the result of calling the superclass method

destroy

This method is called to cleanup an object and its resources. After calling this method, the object should not be used any further in any way, including access to its methods and properties.

To prevent potential memory leaks, all object references will be nulled at the end of destruction sequence, unless clearPropertiesOnDestroy is set to false.

elementFromPoint ( x, y )
private pri

Wrap Ext.Element.fromPagePoint.

This is because in RTL mode we need to reverse any RTLification of the X coordinate because document.elementFromPoint uses LTR.

Parameters

x :  Object

y :  Object

fireEvents ( e, isDrop )
private pri

Iterates over all of the DragDrop elements to find ones we are hovering over or dropping on

Parameters

e :  Event

getBestMatch ( dds ) : Ext.dd.DragDrop

Helper function for getting the best match from the list of drag and drop objects returned by the drag and drop events when we are in INTERSECT mode. It returns either the first object that the cursor is over, or the object that has the greatest overlap with the dragged element.

Parameters

dds :  Ext.dd.DragDrop[]

The array of drag and drop objects targeted

Returns

:Ext.dd.DragDrop

peek :  Boolean (optional)

true to peek at the raw value without calling the getter.

Defaults to: false

Returns

:Object

The config property value.

getCss ( id ) : Object

getElWrapper ( id ) : Ext.dd.DragDropManager.ElementWrapper
deprecated dep private pri

Get the wrapper for the DOM element specified

Parameters

id :  String

the id of the element to get

Returns

:Ext.dd.DragDropManager.ElementWrapper

Deprecated

getInitialConfig ( [name] ) : Object/Mixed

Returns the initial configuration passed to the constructor when instantiating this class.

Given this example Ext.button.Button definition and instance:

Ext.define('MyApp.view.Button', {
    extend: 'Ext.button.Button',
    xtype: 'mybutton',

    scale: 'large',
    enableToggle: true
});

var btn = Ext.create({
    xtype: 'mybutton',
    renderTo: Ext.getBody(),
    text: 'Test Button'
});

Calling btn.getInitialConfig() would return an object including the config options passed to the create method:

xtype: 'mybutton',
renderTo: // The document body itself
text: 'Test Button'

Calling btn.getInitialConfig('text')returns 'Test Button'.

Parameters

name :  String (optional)

Name of the config option to return.

Returns

:Ext.dd.DragDrop[]

the related instances

getZIndex ( element ) : Number
private pri

Collects the z-index of the passed element, looking up the parentNode axis to find an absolutely positioned ancestor which is able to yield a z-index. If found to be not absolutely positionedm returns -1.

This is used when sorting potential drop targets into z-index order so that only the topmost receives over and drop events.

Parameters

element :  Object

Returns

:Number

The z-index of the element, or of its topmost absolutely positioned ancestor. Returns -1 if the element is not absolutely positioned.

handleMouseDown ( e, oDD )
private pri

Parameters

e :  Event

the event

oDD :  Ext.dd.DragDrop

the DragDrop object being dragged

handleMouseMove ( e ) : Boolean
private pri

Internal function to handle the mousemove event. Will be invoked from the context of the html element.

TODO: figure out what we can do about mouse events lost when the user drags objects beyond the window boundary. Currently we can detect this in internet explorer by verifying that the mouse is down during the mousemove event. Firefox doesn't give us the button state on the mousemove event.

Parameters

e :  Event

the event

Returns

:Boolean

handleMouseUp ( e )
private pri

Internal function to handle the mouseup event. Will be invoked from the context of the document.

Parameters

e :  Event

the event

hasConfig ( name )
private pri

Parameters

name :  String

init
private pri

Called the first time an element is registered.

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

Initialize configuration for this class. a typical example:

Ext.define('My.awesome.Class', {
    // The default config
    config: {
        name: 'Awesome',
        isAwesome: true
    },

    constructor: function(config) {
        this.initConfig(config);
    }
});

var awesome = new My.awesome.Class({
    name: 'Super Awesome'
});

alert(awesome.getName()); // 'Super Awesome'

Parameters

instanceConfig :  Object

Returns

:Ext.Base

this

isDragDrop ( id ) : Boolean

Utility function to determine if a given element has been registered as a drag drop item.

Parameters

id :  String

the element id to check

Returns

:Boolean

true if this element is a DragDrop item, false otherwise

isHandle ( id ) : Boolean

Utility function to determine if a given element has been registered as a drag drop handle for the given Drag Drop object.

Parameters

id :  String

the element id to check

Returns

:Boolean

true if this element is a DragDrop handle, false otherwise

isLegalTarget ( oDD, oTargetDD ) : Boolean

Returns true if the specified dd target is a legal target for the specifice drag obj

Parameters

oDD :  Ext.dd.DragDrop

the drag obj

oTargetDD :  Ext.dd.DragDrop

the target

Returns

:Boolean

true if the target is a legal target for the dd obj

isLocked Boolean

Is drag and drop locked?

Returns

:Boolean

True if drag and drop is locked, false otherwise.

isOverTarget ( pt, oTarget ) : Boolean
private pri

Checks the cursor location to see if it over the target

Parameters

pt :  Ext.util.Point

The point to evaluate

oTarget :  Ext.dd.DragDrop

the DragDrop object we are inspecting

Returns

:Boolean

true if the mouse is over the target

isTypeOfDD ( oDD ) : Boolean

My goal is to be able to transparently determine if an object is typeof DragDrop, and the exact subclass of DragDrop. typeof returns "object", oDD.constructor.toString() always returns "DragDrop" and not the name of the subclass. So for now it just evaluates a well-known variable in DragDrop.

Parameters

oDD :  Object

The object to evaluate

Returns

:Boolean

true if typeof oDD = DragDrop

refreshCache ( groups )

Refreshes the cache of the top-left and bottom-right points of the drag and drop objects in the specified group(s). This is in the format that is stored in the drag and drop instance, so typical usage is:

Ext.dd.DragDropManager.refreshCache(ddinstance.groups);

Alternatively:

Ext.dd.DragDropManager.refreshCache({group1:true, group2:true});

TODO: this really should be an indexed array. Alternatively this method could accept both.

Parameters

groups :  Object

an associative array of groups to refresh

regDragDrop ( oDD, sGroup )

Each DragDrop instance must be registered with the DragDropManager. This is executed in DragDrop.init()

Parameters

oDD :  Ext.dd.DragDrop

the DragDrop object to register

sGroup :  String

the name of the group this element belongs to

regHandle ( sDDId, sHandleId )

Each DragDrop handle element must be registered. This is done automatically when executing DragDrop.setHandleElId()

Parameters

sDDId :  String

the DragDrop id this element is a handle for

sHandleId :  String

the id of the element that is the drag handle

removeDDFromGroup ( oDD, sGroup )
private pri

Removes the supplied dd instance from the supplied group. Executed by DragDrop.removeFromGroup, so don't call this function directly.

Parameters

oDD :  Object

sGroup :  Object

setConfig ( name, [value] ) : Ext.Base
chainable ch

Sets a single/multiple configuration options.

Parameters

name :  String/Object

value :  Object (optional)

The value to set for the name parameter.

Returns

:Ext.Base

this

startDrag ( x, y )

Fired when either the drag pixel threshold or the mousedown hold time threshold has been met.

Parameters

x :  Number

the X position of the original mousedown

y :  Number

the Y position of the original mousedown

statics Ext.Class
protected pro

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

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

    constructor: function() {

:Ext.Class

stopDrag ( e )
private pri

Internal function to clean up event handlers after the drag operation is complete

Parameters

e :  Event

the event

stopEvent ( e )

Utility to stop event propagation and event default, if these features are turned on.

Parameters

e :  Event

the event as returned by this.getEvent()

el :  HTMLElement

the element to check

Returns

:Boolean

true if the element looks usable

Static Methods

addConfig ( config, [mixinClass] )
static sta private pri

Adds new config properties to this class. This is called for classes when they are declared, then for any mixins that class may define and finally for any overrides defined that target the class.

Parameters

config :  Object

mixinClass :  Ext.Class (optional)

The mixin class if the configs are from a mixin.

addInheritableStatics ( members ) :
chainable ch static sta private pri

Parameters

members :  Object

Returns

:

addMember ( name, member ) :
chainable ch static sta private pri

Parameters

name :  Object

member :  Object

Returns

:

addMembers ( members, [isStatic], [privacy] ) :
chainable ch static sta

Add methods / properties to the prototype of this class.

Ext.define('My.awesome.Cat', {
    constructor: function() {
        ...
    }
});

 My.awesome.Cat.addMembers({
     meow: function() {
        alert('Meowww...');
     }
 });

 var kitty = new My.awesome.Cat();
 kitty.meow();

Parameters

members :  Object

The members to add to this class.

isStatic :  Boolean (optional)

Pass true if the members are static.

Defaults to: false

privacy :  Boolean (optional)

Pass true if the members are private. This only has meaning in debug mode and only for methods.

Defaults to: false

Returns

:

addStatics ( members ) : Ext.Base
chainable ch static sta

Add / override static properties of this class.

Ext.define('My.cool.Class', {
    ...
});

My.cool.Class.addStatics({
    someProperty: 'someValue',      // My.cool.Class.someProperty = 'someValue'
    method1: function() { ... },    // My.cool.Class.method1 = function() { ... };
    method2: function() { ... }     // My.cool.Class.method2 = function() { ... };
});

Parameters

members :  Object

Returns

:Ext.Base

this

borrow ( fromClass, members ) : Ext.Base
static sta private pri

Borrow another class' members to the prototype of this class.

Ext.define('Bank', {
    money: '$$$',
    printMoney: function() {
        alert('$$$$$$$');
    }
});

Ext.define('Thief', {
    ...
});

Thief.borrow(Bank, ['money', 'printMoney']);

var steve = new Thief();

alert(steve.money); // alerts '$$$'
steve.printMoney(); // alerts '$$$$$$$'

Parameters

fromClass :  Ext.Base

The class to borrow members from

members :  Array/String

The names of the members to borrow

Returns

:Ext.Base

this

callParent ( args )
static sta protected pro

Parameters

args :  Object

callSuper ( args )
static sta protected pro

Parameters

args :  Object

create Object
static sta

Create a new instance of this Class.

Ext.define('My.cool.Class', {
    ...
});

My.cool.Class.create({
    someConfig: true
});

All parameters are passed to the constructor of the class.

Returns

:Object

the created instance.

createAlias ( alias, origin )
static sta

Create aliases for existing prototype methods. Example:

Ext.define('My.cool.Class', {
    method1: function() { ... },
    method2: function() { ... }
});

var test = new My.cool.Class();

My.cool.Class.createAlias({
    method3: 'method1',
    method4: 'method2'
});

test.method3(); // test.method1()

My.cool.Class.createAlias('method5', 'method3');

test.method5(); // test.method3() -> test.method1()

Parameters

alias :  String/Object

The new method name, or an object to set multiple aliases. See flexSetter

origin :  String/Object

The original method name

extend ( parentClass )
static sta private pri

Parameters

parentClass :  Object

getConfigurator Ext.Configurator
static sta private pri

Returns the Ext.Configurator for this class.

Returns

:Ext.Configurator

getName String
static sta

Get the current class' name in string format.

Ext.define('My.cool.Class', {
    constructor: function() {
        alert(this.self.getName()); // alerts 'My.cool.Class'
    }
});

My.cool.Class.getName(); // 'My.cool.Class'

Returns

:String

className

mixin ( name, mixinClass ) :
chainable ch static sta private pri

Used internally by the mixins pre-processor

Parameters

name :  Object

mixinClass :  Object

Returns

:

onExtended ( fn, scope ) :
chainable ch static sta private pri

Parameters

fn :  Object

scope :  Object

Returns

:

override ( members ) : Ext.Base
chainable ch static sta

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

Ext.define('My.Cat', {
    constructor: function() {
        alert("I'm a cat!");
    }
});

My.Cat.override({
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

var kitty = new My.Cat(); // alerts "I'm going to be a cat!"
                          // alerts "I'm a cat!"
                          // alerts "Meeeeoooowwww"

Direct use of this method should be rare. Use Ext.define instead:

Ext.define('My.CatOverride', {
    override: 'My.Cat',
    constructor: function() {
        alert("I'm going to be a cat!");

        this.callParent(arguments);

        alert("Meeeeoooowwww");
    }
});

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

Parameters

members :  Object

The properties to add to this class. This should be specified as an object literal containing one or more properties.

Returns

:Ext.Base

this class
