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.

Summary

This plugin enables user-defined filters for a grid.

In general an gridfilters plugin will be passed to the grid:

Convenience Subclasses

There are several menu subclasses that provide default rendering for various data types

 columns: [
     {text: 'First Name',  dataIndex:'firstname'},
     {text: 'Last Name',  dataIndex:'lastname', filter: 'string'},
     {text: 'seniority', dataIndex: 'seniority', filter: 'number'},
     {text: 'Hired Month',  dataIndex:'hired', filter: 'date'},
     {text: 'Active',  dataIndex:'active', filter: 'boolean'}
 ]

Menu items can also be customised as shown below:

 columns: [
     {
         text: 'First Name',
         dataIndex:'firstname'
     },
     {
         text: 'Last Name',
         filter: {
             type: 'string',
             menu: {
                 items: {
                     like: {
                         placeholder: 'Custom Like...'
                     }
                 }
             }
         }
    },
    {
       text: 'Hired Month',
       filter: {
         type: 'date',
         menu: {
             items: {

No members found using the current filters

configs

Optional Configs

activeFilter : String / Object
private pri

This config holds the current filter. This config is stateful.

Defaults to:

null

getActiveFilter : String / Object

Returns the value of activeFilter

Returns

String / Object

setActiveFilter (activeFilter)

Sets the value of activeFilter

Parameters

activeFilter :  String / Object

id : String

An identifier for the plugin that can be set at creation time to later retrieve the plugin using the getPlugin method. For example:

 var panel = Ext.create({
     xtype: 'panel',

     plugins: {
         foobar: {
             id: 'foo',
             ...
         }
     }
 });

 // later on:
 var plugin = panel.getPlugin('foo');

Available since: 6.2.0

getId String

Retrieves the id. This method Will auto-generate an id if one has not already been configured.

Returns

:String

id

owner : Ext.Base

Defaults to:

null

getOwner : Ext.Base

Returns the value of owner

Returns

Ext.Base

setOwner (owner)

Sets the value of owner

Parameters

owner :  Ext.Base

ownerListeners : Object

The events and associated handlers to which to listen on the owner.

Defaults to:

{
    destroyable: true,
    storechange: 'onOwnerStoreChange'
}

getOwnerListeners : Object

Returns the value of ownerListeners

Returns

Object

setOwnerListeners (ownerListeners)

Sets the value of ownerListeners

Parameters

ownerListeners :  Object

pluginId : String
deprecated dep

Deprecated since version 6.2.0
Use id instead

sourceListeners : Object

The events and associated handlers to which to listen on the source of the connected store. That is, these listeners are attached to the unfiltered collection. When remoteFilter is true there is no unfiltered collection so these listeners are attached to the only collection that exists (which is filtered by the server).

Defaults to:

null

getSourceListeners : Object

Returns the value of sourceListeners

Returns

Object

setSourceListeners (sourceListeners)

Sets the value of sourceListeners

Parameters

sourceListeners :  Object

stateful : Boolean / Object / String[]

This config specifies the config properties that will be persisted using the Ext.state.Provider. If this config is set to true, the configs specified by statefulDefaults will be assumed.

 stateful: true

Otherwise, this config can be an array of strings of the properties to save:

 stateful: [
     'width',
     'height',
     'collapsed'
 ]

The above is equivalent to:

 stateful: {
     width: true,
     height: true,
     collapsed: true
 }

Note: To be truly stateful, an id or stateId must also be assigned.

A stateful object will save its state when any of these config properties change value.

Defaults to:

false

getStateful : Boolean / Object / String[]

Returns the value of stateful

Returns

Boolean / Object / String[]

setStateful (stateful)

Sets the value of stateful

Parameters

stateful :  Boolean / Object / String[]

statefulDefaults : Object / String[]
protected pro

The default set of stateful properties. The form of this config is the same as stateful except this config cannot be a Boolean.

This config is intended for classes to specify so that instances can simply enable statefulness using stateful: true.

Defaults to:

null

getStatefulDefaults : Object / String[]

Returns the value of statefulDefaults

Returns

Object / String[]

setStatefulDefaults (statefulDefaults)

Sets the value of statefulDefaults

Parameters

statefulDefaults :  Object / String[]

stateId : String

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

Defaults to:

null

getStateId : String

Returns the value of stateId

Returns

String

setStateId (stateId)

Sets the value of stateId

Parameters

stateId :  String

storeListeners : Object

The events and associated handlers to which to listen on the store of the owner.

Defaults to:

null

getStoreListeners : Object

Returns the value of storeListeners

Returns

Object

setStoreListeners (storeListeners)

Sets the value of storeListeners

Parameters

storeListeners :  Object

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

$configTransforms : Object / Array
private pri

A prototype-chained object storing transform method names and priorities stored on the class prototype. On first instantiation, this object is converted into an array that is sorted by priority and stored on the constructor.

Defaults to:

{}

autoGenId : Boolean
private pri

true indicates an id was auto-generated rather than provided by configuration.

Defaults to:

false

Available since: 6.7.0

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

destroyed : Boolean

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

Defaults to:

false

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

isPlugin : Boolean
readonly ro

The value true to identify objects of this class or a subclass thereof.

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'

Defaults to:

Base

methods

Instance Methods

_flushStateful
private pri

This method is called before destroy to ensure that this instance's stateful properties are saved to persistent storage. Since this object is about to be destroyed, this cannot be delayed.

_getStateId String
private pri

Returns the state id for this object.

Returns

:String

The stateId or the configured id.

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

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
Use method-callParent instead.

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

clonePlugin ( [overrideCfg] )

Creates clone of the plugin.

Parameters

overrideCfg :  Object (optional)

Additional config for the derived plugin.

constructor ( [config] )

Initializes the plugin.

Parameters

config :  Object (optional)

Configuration object.

destroy

The destroy method is invoked by the owning Component at the time the Component is being destroyed.

destroyMembers ( args )

Destroys member properties by name.

If a property name is the name of a config, the getter is not invoked, so if the config has not been initialized, nothing will be done.

The property will be destroyed, and the corrected name (if the property is a config and config names are prefixed) will set to null in this object's dictionary.

Parameters

args :  String...

One or more names of the properties to destroy and remove from the object.

detachCmp

Plugins that can be disconnected from their host component should implement this method.

Available since: 6.2.0

getCmp Ext.Component

Returns the component to which this plugin is attached.

Returns

:Ext.Component

The owning host component.

getConfig ( [name], [peek], [ifInitialized] ) : Object

Returns a specified config property value. If the name parameter is not passed, all current configuration options will be returned as key value pairs.

Parameters

name :  String (optional)

The name of the config property to get.

peek :  Boolean (optional)

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

Defaults to: false

ifInitialized :  Boolean (optional)

true to only return the initialized property value, not the raw config value, and not to trigger initialization. Returns undefined if the property has not yet been initialized.

Defaults to: false

Returns

:Object

The config property value.

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

:Object/Mixed

The full config object or a single config value when name parameter specified.

getStateBuilder ( [cache] ) : Ext.state.Builder
private pri

Creates a state builder to access or edit this instance's state object. If this instance has a getStatefulOwner, the returned builder will have a parent reference that owner's state builder. This can be an arbitrarily deep chain but does proceed all the way up to the root instance (with no owner) since that is the instance that determines the ultimate state storage key.

Parameters

cache :  Boolean (optional)

Pass true to return a cached builder.

Defaults to: false

Returns

:Ext.state.Builder

getStatefulOwner Ext.state.Stateful/Array
private pri

This method allows a class to specify an owning stateful object. This is used by Ext.plugin.Abstract to save their state as part of their owning Ext.Component.

The return value can be either a Stateful object or an array whose first element is a Stateful object. This object's state will be stored inside the state object of the returned Stateful object. If an array is returned, the elements beyond the first are sub-keys in the state object.

For example, Ext.plugin.Abstract implement this method like so:

 getStatefulOwner: function() {
     return [ this.cmp, 'plugins' ];
 }

The effect of this is to produce a state object like so:

 {
     plugins: {
         pluginId1: {
             //...
         }
     }
 }

In order for a child object's state to be saved and restored, all of its parents must also be stateful (i.e., have a stateId).

Returns

:Ext.state.Stateful/Array

hasConfig ( name )
private pri

Parameters

name :  String

init ( host )

The init method is invoked to formally associate the host component and the plugin.

Subclasses should perform initialization and set up any requires links between the plugin and its host Component in their own implementation of this method.

Parameters

host :  Ext.Component

The host Component which owns this plugin.

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

loadState ( state, stateful ) : Object
private pri

This method is called to load state from the provided state builder. This method should return the config properties loaded from state.

This method, like saveState, can be overridden by derived classes:

 loadState: function(state) {
     var ret = this.callParent([ state ]);

     if (ret.foo) {
         // use custom data...

         delete ret.foo;  // remove it since it isn't a config
     }

     return ret;
 }

When overriding this method, it is also likely necessary to override saveState.

Parameters

state :  Ext.state.Builder

stateful :  Object

The stateful properties as an object keyed by config name.

Returns

:Object

onStatefulChange
private pri

This method is called when any of the stateful configs are modified.

persistState
private pri

Saves the state of this instance to the persistence store. This method is called by the Ext.state.Provider when it is ready to save state to storage.

readStateObject Object
private pri

Returns this instance's state object from the persistence store. This object should contain config properties.

Returns

:Object

saveState ( state, stateful )
private pri

Saves the current state of this object to the provided state builder. By default this method saves the configs specified as stateful.

This method can also be overridden by subclasses to store custom data directly to the state builder:

 saveState: function(state) {
     this.callParent([ state ]);

     state.set('foo', 42);
 }

When overriding this method, it is also likely necessary to override loadState.

Parameters

state :  Ext.state.Builder

The state builder to which to save state.

stateful :  Object

The stateful properties as an object keyed by config name.

setCmp ( host )

Sets the host component to which this plugin is attached. For a plugin to be removable without being destroyed, this method should be provided and be prepared to receive null for the component.

Parameters

host :  Ext.Component

The owning host component.

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

Sets a single/multiple configuration options.

Parameters

name :  String/Object

The name of the property to set, or a set of key value pairs to set.

value :  Object (optional)

The value to set for the name parameter.

Returns

:Ext.Base

this

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() {
        var statics = this.statics();

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


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

        statics.totalCreated++;
    },

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

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

        return cloned;
    }
});


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

    statics: {
        speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'
    },

    constructor: function() {
        this.callParent();
    }
});

var cat = new My.Cat();                 // alerts 'Cat', then alerts 'Cat'

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

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

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

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).

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
