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.

Default value: 'none'.

color : String

The color of the label text.

Default value: '#000' (black).

field : String/String[]

The name(s) of the field(s) to be displayed in the labels. If your chart has 3 series that correspond to the fields 'a', 'b', and 'c' of your model and you only want to display labels for the series 'c', you must still provide an array [null, null, 'c'].

Default value: null.

font : String

Parameters

overlaySurface :  Object

renderer : Function

A function that can be provided to set custom styling properties to each rendered element. It receives (sprite, config, rendererData, index) as parameters.

Defaults to:

null

Parameters

sprite :  Object

The sprite affected by the renderer. The visual attributes are in sprite.attr. The data field is available in sprite.getField().

config :  Object

The sprite configuration. It varies with the series and the type of sprite: for instance, a Line chart sprite might have just the x and y properties while a Bar chart sprite also has width and height. A type might be present too. For instance to draw each marker and each segment of a Line chart, the renderer is called with the config.type set to either marker or line.

rendererData :  Object

A record with different properties depending on the type of chart. The only guaranteed property is rendererData.store, the store used by the series. In some cases, a store may not exist: for instance a Gauge chart may read its value directly from its configuration; in this case rendererData.store is null and the value is available in rendererData.value.

index :  Number

The index of the sprite. It is usually the index of the store record associated with the sprite, in which case the record can be obtained with store.getData().items[index]. If the chart is not associated with a store, the index represents the index of the sprite within the series. For instance a Gauge chart may have as many sprites as there are sectors in the background of the gauge, plus one for the needle.

Returns

:Object

The attributes that have been changed or added. Note: it is usually possible to add or modify the attributes directly into the config parameter and not return anything, but returning an object with only those attributes that have been changed may allow for optimizations in the rendering of some series. Example to draw every other marker in red:

 renderer: function (sprite, config, rendererData, index) {
     if (config.type === 'marker') {
         return { strokeStyle: (index % 2 === 0 ? 'red' : 'black') };
     }
 }

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:

false

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

fieldCategoryX
private pri

Tells which store record fields should be used for a specific axis direction. E.g. for

fieldCategory<direction>: ['<fieldConfig1>', '<fieldConfig2>', ...]

the field names from the following configs will be used:

series.<fieldConfig1>Field, series.<fieldConfig2>Field, ...

Defaults to:

[
    'X'
]

getItemForPoint

For a given x/y point relative to the main rect, find a corresponding item from this series, if any.

Defaults to:

Ext.emptyFn

Parameters

x :  Number

y :  Number

target :  Object (optional)

optional target to receive the result

Returns

:Object

An object describing the item, or null if there is no matching item. The exact contents of this object will vary by series type, but should always contain at least the following:

record :  Ext.data.Model

the record of the item.

point :  Array

the x/y coordinates relative to the chart box of a single point for this data item, which can be used as e.g. a tooltip anchor point.

sprite :  Ext.draw.sprite.Sprite

the item's rendering Sprite.

subSprite :  Number

the index if sprite is an instancing sprite.

getSprites

Performs drawing of this series.

Defaults to:

Ext.emptyFn

hasListeners : Object
readonly ro

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

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

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

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.

Defaults to:

false

Available since: 5.0.0

isInstance : Boolean
readonly ro protected pro

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

Defaults to:

true

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() {
        alert(this.self.speciesName); // dependent on 'this'
    },

    clone: function() {
        return new this.self();
    }
});


Ext.define('My.SnowLeopard', {
    extend: 'My.Cat',
    statics: {
        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'

methods

Instance Methods

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

Appends an after-event handler.

Same as addListener with order set to 'after'.

Parameters

eventName :  String/String[]/Object

The name of the event to listen for.

fn :  Function/String

The method the event invokes.

scope :  Object (optional)

The scope for fn.

options :  Object (optional)

An object containing handler configuration.

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

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

Same as addListener with order set to 'before'.

Parameters

eventName :  String/String[]/Object

The name of the event to listen for.

fn :  Function/String

The method the event invokes.

scope :  Object (optional)

The scope for fn.

options :  Object (optional)

An object containing handler configuration.

addDeprecations ( deprecations )
private pri

This method applies a versioned, deprecation declaration to this class. This is typically called by the deprecated config.

Parameters

deprecations :  Object

addEvents ( eventNames )
deprecated dep

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 a value of true or the first event name string if multiple event names are being passed as separate parameters.

Deprecated since version 2.0
It's no longer needed to add events before firing.

addListener ( eventName, fn, [scope], [options], [order] )

Appends an event handler to this object. You can review the available handlers by looking at the 'events' section of the documentation for the component you are working with.

Combining Options

Using the options argument, it is possible to combine different types of listeners:

A delayed, one-time listener:

container.addListener('tap', this.handleTap, 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:

container.addListener({
    tap  : this.onTap,
    swipe: this.onSwipe,

    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

container.addListener({
    tap  : { fn: this.onTap, scope: this, single: true },
    swipe: { fn: button.onSwipe, scope: button }
});

See the Events Guide for more.

Parameters

eventName :  String/String[]/Object

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

fn :  Function/String

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.

This object may contain any of the following properties:

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

delay :  Number (optional)

The number of milliseconds to delay the invocation of the handler after the event fires.

single :  Boolean (optional)

true to add a handler to handle just the next firing of the event, and then remove itself.

order :  String (optional)

The order of when the listener should be added into the listener queue.

If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.

Available options are before, current and after.

Defaults to:

current

buffer :  Number (optional)

Causes the handler to be 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.

element :  String (optional)

If this observable is a Component, allows you to add a listener onto a element of the component using the element's reference.

Ext.create('Ext.Component', {
    listeners: {
        element: 'element',
        tap: function() {
            alert('element tap!');
        }
    }
});

In Sencha Touch, All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

delegate :  String (optional)

For Ext.dom.Element, a simple DOM selector to filter the target or look for a descendant of the target.

Sencha Touch Components can use Ext.ComponentQuery selectors to filter child Components.

// Create a container with a two children; a button and a toolbar
var container = Ext.create('Ext.Container', {
    items: [
        {
            xtype: 'toolbar',
            docked: 'top',
            title: 'My Toolbar'
        },
        {
           xtype: 'button',
           text: 'My Button'
        }
    ]
});

container.addListener({
    // Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
    delegate: 'button',

    tap: function() {
        alert('Button tapped!');
    }
});

capture :  Boolean

true to initiate capture which will fire the listeners on the target Element before any descendant Elements. Normal events start with the target element and propagate upward to ancestor elements, whereas captured events propagate from the top of the DOM downward to descendant elements. This option achieves the same result as the useCapture parameter in the standard JavaScript addEventListener method.

order :  String (optional)

The order of when the listener should be added into the listener queue. Possible values are before, current and after.

Defaults to: 'current'

addManagedListener ( object, eventName, [fn], [scope], [options] )
deprecated dep

Adds listeners to any Observable object (or Element) which are automatically removed when this Component is destroyed.

Parameters

object :  Ext.mixin.Observable/HTMLElement

The item to which to add a listener/listeners.

eventName :  Object/String

The event name, or an object containing event name properties.

fn :  Function (optional)

If the eventName parameter was an event name, this is the handler function.

scope :  Object (optional)

If the eventName parameter was an event name, this is the scope in which the handler function is executed.

options :  Object (optional)

If the eventName parameter was an event name, this is the addListener options.

Deprecated since version 2.0
All listeners are now automatically managed where necessary. Simply use addListener.

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 methods.

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

     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',

     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 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 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

Parameters

object :  Ext.mixin.Observable/HTMLElement

The item to which to add a listener/listeners.

eventName :  Object/String

The event name, or an object containing event name properties.

fn :  Function (optional)

If the eventName parameter was an event name, this is the handler function.

scope :  Object (optional)

If the eventName parameter was an event name, this is the scope in which the handler function is executed.

options :  Object (optional)

If the eventName parameter was an event name, this is the addListener options.

Deprecated since version 2.0.0
This is now done automatically

mun ( object, eventName, [fn], [scope] )
deprecated dep

Alias for removeManagedListener. Adds listeners to any Observable object (or Element) which are automatically removed when this Component is destroyed.

Parameters

object :  Ext.mixin.Observable/HTMLElement

The item to which to add a listener/listeners.

eventName :  Object/String

The event name, or an object containing event name properties.

fn :  Function (optional)

If the eventName parameter was an event name, this is the handler function.

on ( eventName, fn, [scope], [options], [order] )

Alias for addListener. Appends an event handler to this object. You can review the available handlers by looking at the 'events' section of the documentation for the component you are working with.

Combining Options

Using the options argument, it is possible to combine different types of listeners:

A delayed, one-time listener:

container.addListener('tap', this.handleTap, 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:

container.addListener({
    tap  : this.onTap,
    swipe: this.onSwipe,

    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

container.addListener({
    tap  : { fn: this.onTap, scope: this, single: true },
    swipe: { fn: button.onSwipe, scope: button }
});

See the Events Guide for more.

Parameters

eventName :  String/String[]/Object

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

fn :  Function/String

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.

This object may contain any of the following properties:

scope :  Object (optional)

The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

delay :  Number (optional)

Available options are before, current and after.

Defaults to:

current

buffer :  Number (optional)

Causes the handler to be 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.

element :  String (optional)

If this observable is a Component, allows you to add a listener onto a element of the component using the element's reference.

Ext.create('Ext.Component', {
    listeners: {
        element: 'element',
        tap: function() {
            alert('element tap!');
        }
    }
});

In Sencha Touch, All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

delegate :  String (optional)

For Ext.dom.Element, a simple DOM selector to filter the target or look for a descendant of the target.

Sencha Touch Components can use Ext.ComponentQuery selectors to filter child Components.

// Create a container with a two children; a button and a toolbar
var container = Ext.create('Ext.Container', {
    items: [
        {
            xtype: 'toolbar',
            docked: 'top',
            title: 'My Toolbar'
        },
        {
           xtype: 'button',
           text: 'My Button'
        }
    ]
});

container.addListener({
    // Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
    delegate: 'button',

    tap: function() {
        alert('Button tapped!');
    }
});

capture :  Boolean

true to initiate capture which will fire the listeners on the target Element before any descendant Elements. Normal events start with the target element and propagate upward to ancestor elements, whereas captured events propagate from the top of the DOM downward to descendant elements. This option achieves the same result as the useCapture parameter in the standard JavaScript addEventListener method.

order :  String (optional)

The order of when the listener should be added into the listener queue. Possible values are before, current and after.

Defaults to: 'current'

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

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

    constructor: function() {
        var statics = this.statics();

        alert(statics.speciesName);     // always equals to 'Cat' no matter what 'this' refers to
                                        // equivalent to: My.Cat.speciesName

        alert(this.self.speciesName);   // dependent on 'this'

        statics.totalCreated++;
    },

    clone: function() {
        var cloned = new this.self();   // dependent on 'this'

        cloned.groupName = this.statics().speciesName;   // equivalent to: My.Cat.speciesName

alert(My.Cat.totalCreated);             // alerts 3

Returns

:Ext.Class

suspendEvent ( eventName )

Suspends firing of the named event(s).

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

Parameters

eventName :  String...

Multiple event names to suspend.

suspendEvents ( queueSuspended )

Suspends the firing of all events. (see resumeEvents)

Parameters

queueSuspended :  Boolean

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

});

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

var steve = new Thief();

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

Parameters

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 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).
