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 JS 6.5.0 - Modern Toolkit


top

Ext.app.Application

Summary

Represents an Ext JS application, which is typically a single page app using a Viewport.

An application consists of one or more Views. The behavior of a View is managed by its corresponding Ext.app.ViewController and Ext.app.ViewModel.

Global activities are coordinated by Ext.app.Controller which are ultimately instantiated by an instance of this (or a derived) class.

Ext.application({
    name: 'MyApp',

    // The name of the initial view to create. With the classic toolkit this class
    // will gain a "viewport" plugin if it does not extend Ext.Viewport. With the
    // modern toolkit, the main view will be added to the Viewport.
    //
    //mainView: 'Main.view.main.Main'
});

This does several things. First it creates a global variable called 'MyApp' - all of your Application's classes (such as its Models, Views and Controllers) will reside under this single namespace, which drastically lowers the chances of colliding global variables.

The MyApp global will also have a getApplication method to get a reference to the current application:

var app = MyApp.getApplication();

Telling Application about the rest of the app

Because an Ext.app.Application represents an entire app, we should tell it about the other parts of the app - namely the Models, Views and Controllers that are bundled with the application. Let's say we have a blog management app; we might have Models and Controllers for Posts and Comments, and Views for listing, adding and editing Posts and Comments. Here's how we'd tell our Application about all these things:

Ext.application({
    name: 'Blog',

    models: ['Post', 'Comment'],

    controllers: ['Posts', 'Comments'],

    launch: function() {
        ...
    }
});

Note that we didn't actually list the Views directly in the Application itself. This is because Views are managed by Controllers, so it makes sense to keep those dependencies there. The Application will load each of the specified Controllers using the pathing conventions laid out in the application architecture guide - in this case expecting the controllers to reside in app/controller/Posts.js and app/controller/Comments.js. In turn, each Controller simply needs to list the Views it uses and they will be automatically loaded. Here's how our Posts controller like be defined:

Ext.define('MyApp.controller.Posts', {
    extend: 'Ext.app.Controller',
    views: ['posts.List', 'posts.Edit'],

    //the rest of the Controller here
});

Because we told our Application about our Models and Controllers, and our Controllers about their Views, Ext JS will automatically load all of our app files for us. This means we don't have to manually add script tags into our html files whenever we add a new class, but more importantly it enables us to create a minimized build of our entire application using Sencha Cmd.

Deriving from Ext.app.Application

Typically, applications do not derive directly from Ext.app.Application. Rather, the configuration passed to Ext.application mimics what you might do in a derived class. In some cases, however, it can be desirable to share logic by using a derived class from Ext.app.Application.

Derivation works as you would expect, but using the derived class should still be the job of the Ext.application method.

Ext.define('MyApp.Application', {
    extend: 'Ext.app.Application',
    name: 'MyApp',
    ...
});

Ext.application('MyApp.Application');

For more information about writing Ext JS applications, please see the application architecture guide.

configs

Optional Configs

appFolder : String

The path to the directory which contains all application's classes. This path will be registered via Ext.Loader#setPath for the namespace specified in the name config.

Defaults to:

"app"

application : Ext.app.Application
readonly ro

The Ext.app.Application for this controller accessible via the getApplication method.

Defaults to:

null

getApplication : Ext.app.Application

Returns the value of application

Returns

Ext.app.Application

setApplication (application)

Sets the value of application

Parameters

application :  Ext.app.Application

appProperty : String

The name of a property to be assigned to the main namespace to gain a reference to this application. Can be set to an empty value to prevent the reference from being created

Ext.application({
    name: 'MyApp',
    appProperty: 'myProp',

    launch: function() {
        console.log(MyApp.myProp === this);
    }
});

Defaults to:

'app'

getAppProperty : String

Returns the value of appProperty

Returns

String

setAppProperty (appProperty)

Sets the value of appProperty

Parameters

appProperty :  String

control : Object

Adds listeners to components selected via Ext.ComponentQuery. Accepts an object containing component paths mapped to a hash of listener functions. The function value may also be a string matching the name of a method on the controller.

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

 Ext.define('MyApp.controller.Users', {
     extend: 'Ext.app.Controller',

     control: {
         'useredit button[action=save]': {
             click: 'updateUser'
         }
     },

     updateUser: function(button) {
         console.log('clicked the Save button');
     }
 });

The method you pass to the listener will automatically be resolved on the controller. In this case, the updateUser method that will get executed on the button click event will resolve to the updateUser method on the controller,

See Ext.ComponentQuery for more information on component selectors.

getControl : Object

Returns the value of control

Returns

Object

setControl (control)

Sets the value of control

Parameters

control :  Object

controllers : String / String[]

Names of Ext.app.Controller that the app uses. By default, the framework will look for the controllers in the "controller" folder within the appFolder. Controller classes should be named using the syntax of "{appName}.controller.{ClassName}" with additional sub-folders under the "controller" folder specified within the class name following "controller.".

// by default, the following controller class would be located at:
// app/controller/Main.js
controllers: '.Main' // or 'MyApp.controller.Main'

// while the following would be located at:
// app/controller/customer/Main.js
controllers: 'customer.Main' // or 'MyApp.controller.customer.Main'

Note: If the controller has a different namespace than that of the application you will need to specify the full class name as well as define a path in the Loader's paths config or setPath method.

currentProfile : Ext.app.Profile

Defaults to:

null

Available since: 6.0.1

getCurrentProfile : Ext.app.Profile

Returns the value of currentProfile

Returns

Ext.app.Profile

setCurrentProfile (currentProfile)

Sets the value of currentProfile

Parameters

currentProfile :  Ext.app.Profile

defaultToken : String

The default token to be used at application launch if one is not present. Often this is set to something like 'home'.

Defaults to:

null

getDefaultToken : String

Returns the value of defaultToken

Returns

String

setDefaultToken (defaultToken)

Sets the value of defaultToken

Parameters

defaultToken :  String

extend : String

A class name to use with the Ext.application call. The class must also extend Ext.app.Application.

Ext.define('MyApp.Application', {
    extend: 'Ext.app.Application',

    launch: function() {
        Ext.direct.Manager.addProvider(Ext.REMOTING_API);
    }
});

Ext.application({
    extend: 'MyApp.Application'
});

The glyphFontFamily to use for this application. Used as the default font-family for all components that support a glyph config.

Defaults to:

null

getGlyphFontFamily : String

Returns the value of glyphFontFamily

Returns

String

setGlyphFontFamily (glyphFontFamily)

Sets the value of glyphFontFamily

Parameters

glyphFontFamily :  String

id : String

The id of this controller. You can use this id when dispatching.

For an example of dispatching, see the examples under the listen config.

If an id is not explicitly set, it will default to the controller's full classname.

Defaults to:

undefined

getId String

Retrieves the id of this component. Will autogenerate an id if one has not already been set.

Returns

:String
id

setId (id)

Sets the value of id

Parameters

id :  String

listen : Object

Adds listeners to different event sources (also called "event domains"). The primary event domain is that of components, but there are also other event domains: Ext.app.domain.Global domain that intercepts events fired from Ext.GlobalEvents Observable instance, Ext.app.domain.Controller domain can be used to listen to events fired by other Controllers, Ext.app.domain.Store domain gives access to Store events, and Ext.app.domain.Direct domain can be used with Ext Direct Providers to listen to their events.

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

 Ext.define('AM.controller.Users', {
     extend: 'Ext.app.Controller',

     listen: {
         controller: {
             '#foo': {
                 bar: 'onFooBar'
             }
         }
     }
 });

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

 Ext.define('AM.controller.Users', {
     extend: 'Ext.app.Controller',

     listen: {
         controller: {
             '*': {
                 bar: 'onAnyControllerBar'
             }
         },
         store: {
             '#baz': {
                 baz: 'onStoreBaz'
             }
         }
     }
 });

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

 Ext.define('AM.controller.Users', {
     extend: 'Ext.app.Controller',

     listen: {
         global: {            // Global events are always fired
             idle: 'onIdle'   // from the same object, so there
         }                    // are no selectors
     }
 });

As this relates to components, the following example:

 Ext.define('AM.controller.Users', {
     extend: 'Ext.app.Controller',

     listen: {
         component: {
             'useredit button[action=save]': {
                 click: 'updateUser'
             }
         }
     }
 });

Is equivalent to:

 Ext.define('AM.controller.Users', {
     extend: 'Ext.app.Controller',

     control: {
         'useredit button[action=save]': {
             click: 'updateUser'
         }
     }
 });

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

 Ext.define('AM.controller.Users', {
     extend: 'Ext.app.Controller',

     listen: {
         global: {
             idle: 'onIdle'
         },
         controller: {
             '*': {
                 foobar: 'onAnyFooBar'
             },
             '#foo': {
                 bar: 'onFooBar'
             }
         },
         component: {
             'useredit button[action=save]': {
                 click: 'updateUser'
             }
         },
         store: {
             '#qux': {
                 load: 'onQuxLoad'
             }
         }
     }
 });

Defaults to:

null

getListen : Object

Returns the value of listen

Returns

Object

setListen (listen)

Sets the value of listen

Parameters

listen :  Object

listeners : Object

A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once.

DOM events from Ext JS Ext.Component

While some Ext JS Component classes export selected DOM events (e.g. "click", "mouseover" etc), this is usually only done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a child element of a Component, we need to specify the element option to identify the Component property to add a DOM listener to:

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

setListeners ( listeners )

An alias for addListener. In versions prior to 5.1, listeners had a generated setter which could be called to add listeners. In 5.1 the listeners config is not processed using the config system and has no generated setter, so this method is provided for backward compatibility. The preferred way of adding listeners is to use the on method.

Parameters

listeners :  Object

The listeners

mainView : String / Object / Ext.Component

The application class to be used as the main viewport view for the application. The view will be configured with the viewport plugin to ensure the view takes up all available space in the browser viewport. The main view will be created after the application's init method is called and before the launch method. The main view should be an application class type and not a class from the framework.

The main view value may be:

  • string representing the full class name of the main view or the partial class name following "AppName.view." (provided your main view class follows that convention).
  • config object for the main view
  • main view class instance

    Ext.define('MyApp.view.main.Main', {

     extend: 'Ext.panel.Panel',
     xtype: 'mainview',
     title: 'Main Viewport View'
    

    });

    Ext.application({

     name : 'MyApp',
    
     mainView: 'MyApp.view.main.Main'
     // mainView: 'main.Main'
     // mainView: new MyApp.view.main.Main()
     // mainView: { xtype: 'mainview' }
    

    });

Note: You may also call setMainView at runtime if you require logic within the application's launch method to be processed prior to the creation of the main view.

Defaults to:

null

getMainView : String / Object / Ext.Component

Returns the value of mainView

Returns

String / Object / Ext.Component

setMainView (mainView)

Sets the value of mainView

Parameters

mainView :  String / Object / Ext.Component

models : String / String[]

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

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

This is equivalent to:

 Ext.define("MyApp.controller.Foo", {
     extend: "Ext.app.Controller",
     requires: ['MyApp.model.User', 'MyApp.model.Vehicle'],

     getUserModel: function() {
         return this.getModel("User");
     },

     getVehicleModel: function() {
         return this.getModel("Vehicle");
     }
 });

Note: If the model has a different namespace than that of the application you will need to specify the full class name as well as define a path in the Loader's paths config or setPath method.

Defaults to:

null

moduleClassName
private pri

Defaults to:

null

getModuleClassName

Returns the value of moduleClassName

Returns

setModuleClassName (moduleClassName)

Sets the value of moduleClassName

Parameters

moduleClassName :  Object

name : String

The name of your application. This will also be the namespace for your views, controllers models and stores. Don't use spaces or special characters in the name. Application name is mandatory.

Defaults to:

''

getName : String

Returns the value of name

Returns

String

setName (name)

Sets the value of name

Parameters

name :  String

namespaces : String / String[]

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

 Ext.application({
     name: 'MyApp',

     namespaces: ['Common.code'],

     controllers: [ 'Common.code.controller.Foo', 'Bar' ]
 });

 Ext.define('Common.code.controller.Foo', {
     extend: 'Ext.app.Controller',

     models: ['Foo'],    // Loads Common.code.model.Foo
     views:  ['Bar']     // Loads Common.code.view.Bar
 });

 Ext.define('MyApp.controller.Bar', {
     extend: 'Ext.app.Controller',

     models: ['Foo'],    // Loads MyApp.model.Foo
     views:  ['Bar']     // Loads MyApp.view.Bar
 });

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

Defaults to:

[]

paths : Object

Additional load paths to add to Ext.Loader. See Ext.Loader#paths config for more details.

Defaults to:

null

profiles : String / String[]

Names of the profiles that the app uses.

Defaults to:

[]

getProfiles : String / String[]

Returns the value of profiles

Returns

String / String[]

setProfiles (profiles)

Sets the value of profiles

Parameters

profiles :  String / String[]

quickTips : Boolean / Object

true to enable quick tips to be read from the DOM and displayed by the Ext.tip.Manager. Pass the object form as a configuration for Ext.tip.Manager.

Defaults to:

false

Available since: 6.2.0

refs : Object / Object[]

The refs config creates a getter method on the controller that internally uses Ext.ComponentQuery to fetch the component instance using the configured selector. The following example will add the getList method to the controller and will return the first component in the application hierarchy with an xtype of "grid". By default, undefined will be returned when the query does not locate the target component.

Ext.define('MyApp.controller.Foo', {
    extend: 'Ext.app.Controller',

    refs: [{
        ref: 'list',
        selector: 'grid'
    }]
});

The following fields may be used in the ref definition:

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

The following example will create a getList and getUser method on the controller.

Ext.define('MyApp.controller.Foo', {
    extend: 'Ext.app.Controller',

    refs: [{
        list: 'grid',
        user: {
            autoCreate: true,
            selector: 'form',
            xtype: 'form'
        }
    }]
});

Defaults to:

null

getRefs : Object / Object[]

Returns the value of refs

Returns

Object / Object[]

setRefs (refs)

Sets the value of refs

Parameters

refs :  Object / Object[]

routes : Object

An object of routes to handle hash changes. A route can be defined in a simple way:

routes: {
    'foo/bar': 'handleFoo',
    'user/:id': 'showUser'
}

Where the property is the hash (which can accept a parameter defined by a colon) and the value is the method on the controller to execute. The parameters will get sent in the action method.

If no routes match a given hash, an Ext.GlobalEvents#unmatchedroute event will be fired. This can be listened to in four ways:

Ext.on('unmatchedroute', function(token) {});

Ext.define('MyApp.controller.Foo', {
    extend: 'Ext.app.Controller',

    listen: {
        global: {
            unmatchedroute: 'onUnmatchedRoute'
        }
    },

    onUnmatchedRoute: function(token) {}
});

Ext.application({
    name: 'MyApp',

    listen: {
        global: {
            unmatchedroute: 'onUnmatchedRoute'
        }
    },

    onUnmatchedRoute: function(token) {}
});

Ext.application({
    name: 'MyApp',

    listeners: {
        unmatchedroute: 'onUnmatchedRoute'
    },

    onUnmatchedRoute: function(token) {}
});

There is also a complex means of defining a route where you can use a before action and even specify your own RegEx for the parameter:

routes: {
    'foo/bar': {
        action: 'handleFoo',
        before: 'beforeHandleFoo'
    },
    'user/:id': {
        action: 'showUser',
        before: 'beforeShowUser',
        conditions: {
            ':id': '([0-9]+)'
        }
    }
}

This will only match if the id parameter is a number.

The before action allows you to cancel an action. Every before action will get passed an action argument with a resume and stop methods as the last argument of the method and you MUST execute either method:

beforeHandleFoo: function (action) {
    //some logic here

    //this will allow the handleFoo action to be executed
    action.resume();
},
handleFoo: function () {
    //will get executed due to true being passed in callback in beforeHandleFoo
},
beforeShowUser: function (id, action) {
    //allows for async process like an Ajax
    Ext.Ajax.request({
        url: 'foo.php',
        success: function () {
            //will not allow the showUser method to be executed but will continue other queued actions.
            action.stop();
        },
        failure: function () {
            //will not allow the showUser method to be executed and will not allow other queued actions to be executed.
            action.stop(true);
        }
    });
},
showUser: function (id) {
    //will not get executed due to false being passed in callback in beforeShowUser
}

You MUST execute the resume or stop method on the action argument. Executing action.resume(); will continue the action, action.stop(); will prevent further execution.

The default RegEx that will be used is ([%a-zA-Z0-9\\-\\_\\s,]+) but you can specify any that may suit what you need to accomplish. An example of an advanced condition may be to make a parameter optional and case-insensitive:

routes: {
    'user:id': {
        action: 'showUser',
        before: 'beforeShowUser',
        conditions: {
            ':id': '(?:(?:\/){1}([%a-z0-9_,\s\-]+))?'
        }
    }
}

Each route can be named; this allows for the route to be looked up by name instead of url. By default, the route's name will be the url you configure but you can provide the name config to override the default:

routes: {
    'user:id': {
        action: 'showUser',
        before: 'beforeShowUser',
        name: 'user',
        conditions: {
            ':id': '(?:(?:\/){1}([%a-z0-9_,\s\-]+))?'
        }
    }
}

The user:id route can not be looked up via the user name which is useful when using redirectTo.

A wildcard route can also be defined which works exactly like any other route but will always execute before any other route. To specify a wildcard route, use the * as the url:

routes: {
    '*': 'onToken'
}

Since a wildcard route will execute before any other route, it can delay the execution of other routes allowing for such things like a user session to be retrieved:

routes: {
    '*': {
        before: 'onBeforeToken'
    }
},

onBeforeToken: function () {
    return Ext.Ajax.request({
        url: '/user/session'
    });
}

In the above example, no other route will execute unless that request returns successfully.

You can also use a wildcard route if you need to defer routes until a store has been loaded when an application first starts up:

routes: {
    '*': {
        before: 'onBeforeToken'
    }
},

onBeforeToken: function (action) {
    var store = Ext.getStore('Settings');

    if (store.loaded) {
        action.resume();
    } else {
        store.on('load', action.resume, action, { single: true });
    }
}

Defaults to:

null

getRoutes : Object

Returns the value of routes

Returns

Object

setRoutes (routes)

Sets the value of routes

Parameters

routes :  Object

scope : Object

The scope to execute the launch function in. Defaults to the Application instance.

Defaults to:

undefined

stores : String / String[]

Array of stores to require from AppName.store namespace and to generate getter methods for. For example:

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

This is equivalent to:

 Ext.define("MyApp.controller.Foo", {
     extend: "Ext.app.Controller",

     requires: [
         'MyApp.store.Users',
         'MyApp.store.Vehicles'
     ]

     getUsersStore: function() {
         return this.getStore("Users");
     },

     getVehiclesStore: function() {
         return this.getStore("Vehicles");
     }
 });

Note: If the store has a different namespace than that of the application you will need to specify the full class name as well as define a path in the Loader's paths config or setPath method.

Defaults to:

null

viewport : Object

Any configuration to be passed on to the Ext.Viewport.

Defaults to:

null

Available since: 6.5.0

getViewport : Object

Returns the value of viewport

Returns

Object

setViewport (viewport)

Sets the value of viewport

Parameters

viewport :  Object

views : String / String[]

Array of views to require from AppName.view namespace and to generate getter methods for. For example:

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

This is equivalent to:

 Ext.define("MyApp.controller.Foo", {
     extend: "Ext.app.Controller",
     requires: ['MyApp.view.List', 'MyApp.view.Detail'],

     getListView: function() {
         return this.getView("List");
     },

     getDetailView: function() {
         return this.getView("Detail");
     }
 });

Note: If the view has a different namespace than that of the application you will need to specify the full class name as well as define a path in the Loader's paths config or setPath method.

Defaults to:

null

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

$eventOptions
private pri

Matches options property names within a listeners specification object - property names which are never used as event names.

Defaults to:

{
    scope: 1,
    delay: 1,
    buffer: 1,
    onFrame: 1,
    single: 1,
    args: 1,
    destroyable: 1,
    priority: 1,
    order: 1
}

$vetoClearingPrototypeOnDestroy
private pri

We don't want the base destructor to clear the prototype because our destroyObservable handler must be called the very last. It will take care of the prototype after completing Observable destruction sequence.

Defaults to:

true

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
protected pro

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

Defaults to:

false

eventsSuspended
private pri

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

Defaults to:

0

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 (via observe) 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

isObservable : Boolean

true in this class to identify an object as an instantiated Observable, or 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'

methods

Instance Methods

_addDeclaredListeners ( listeners ) : Boolean
private pri

Adds declarative listeners as nested arrays of listener objects.

Parameters

listeners :  Array

Returns

:Boolean
`true` if any listeners were added

activate

Allow the controller to resume receiving events from the event bus. Routes will also be able to begin firing on this controller. Also see deactivate.

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

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

The on method is shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("itemclick", this.onItemClick, this);

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

myGridPanel.on({
    cellclick: this.onCellClick,
    select: this.onSelect,
    viewready: this.onViewReady,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellclick: {fn: this.onCellClick, scope: this, single: true},
    viewready: {fn: panel.onViewReady, scope: panel}
});

Names of methods in a specified scope may also be used:

myGridPanel.on({
    cellclick: {fn: 'onCellClick', scope: this, single: true},
    viewready: {fn: 'onViewReady', scope: panel}
});

Parameters

eventName :  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 (optional)

The method the event invokes or the *name* of the method within the specified scope. Will be called with arguments given to Ext.util.Observable#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. **Note:** The options object will also be passed as the last argument to every event handler. This object may contain any of the following properties:

scope :  Object

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

delay :  Number

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

single :  Boolean

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

buffer :  Number

Causes the handler to be scheduled to run in an Ext.util.DelayedTask 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.

onFrame :  Number

Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.

target :  Ext.util.Observable

Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

element :  String

This option is only valid for listeners bound to Ext.Component. The name of a Component property which references an Ext.dom.Element to add a listener to.

This option is useful during Component construction to add DOM event listeners to elements of Ext.Component which will exist only after the Component is rendered.

For example, to add a click listener to a Panel's body:

  var panel = new Ext.panel.Panel({
                              title: 'The title',
                              listeners: {
                                  click: this.handlePanelClick,
                                  element: 'body'
                              }
                          });
                        

In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.

 panel.body.un(...)
                        

delegate :  String (optional)

A simple selector to filter the event target or look for a descendant of the target.

The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

See the delegate example below.

capture :  Boolean (optional)

When set to true, the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase.

The capture option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

stopPropagation :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopPropagation on the event object before firing the handler.

preventDefault :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call preventDefault on the event object before firing the handler.

stopEvent :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopEvent on the event object before firing the handler.

args :  Array (optional)

Optional arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these arguments.

destroyable :  Boolean (optional)

When specified as true, the function returns a destroyable object. An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un; particularly when removing multiple listeners. NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config.

Defaults to:

false

priority :  Number (optional)

An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.

order :  String (optional)

A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:

  • 'before': equal to a priority of 100
  • 'current': equal to a priority of 0 or default priority
  • 'after': equal to a priority of -100

Defaults to:

'current'

order :  String (optional)

A shortcut for the `order` event option. Provided for backward compatibility. Please use the `priority` event option instead. **Combining Options** Using the options argument, it is possible to combine different types of listeners: A delayed, one-time listener. myPanel.on('hide', this.handleClick, 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 handlers and handler configs. grid.on({ itemclick: 'onItemClick', itemcontextmenu: grid.onItemContextmenu, destroy: { fn: function () { // function called within the 'altCmp' scope instead of grid }, scope: altCmp // unique scope for the destroy handler }, scope: grid // default scope - provided for example clarity }); **Delegate** This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example: var panel = Ext.create({ xtype: 'panel', renderTo: document.body, title: 'Delegate Handler Example', frame: true, height: 220, width: 220, html: '

BODY TITLE

Body content' }); // The click handler will only be called when the click occurs on the // delegate: h1.myTitle ("h1" tag with class "myTitle") panel.on({ click: function (e) { console.log(e.getTarget().innerHTML); }, element: 'body', delegate: 'h1.myTitle' });

Defaults to: 'current'

Returns

:Object
**Only when the `destroyable` option is specified. ** A `Destroyable` object. An object which implements the destroy method which removes all listeners added in this call. For example: this.btnListeners = = myButton.on({ destroyable: true mouseover: function() { console.log('mouseover'); }, mouseout: function() { console.log('mouseout'); }, click: function() { console.log('click'); } }); And when those listeners need to be removed: Ext.destroy(this.btnListeners); or this.btnListeners.destroy();

addManagedListener ( item, ename, [fn], [scope], [options] ) : Object

The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.

Example:

Ext.define('Foo', {
    extend: 'Ext.Component',

    initComponent: function () {
        this.addManagedListener(MyApp.SomeGlobalSharedMenu, 'show', this.doSomething);
        this.callParent();
    }
});

As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.

As of version 5.1 it is no longer necessary to use this method in most cases because listeners are automatically managed if the scope object provided to addListener is an Observable instance. However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item to which to add a listener/listeners.

ename :  Object/String

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

fn :  Function/String (optional)

If the `ename` parameter was an event name, this is the handler function or the name of a method on the specified scope.

scope :  Object (optional)

If the `ename` parameter was an event name, this is the scope (`this` reference) in which the handler function is executed.

options :  Object (optional)

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

Returns

:Object
**Only when the `destroyable` option is specified. ** A `Destroyable` object. An object which implements the destroy method which removes all listeners added in this call. For example: this.btnListeners = myButton.mon({ destroyable: true mouseover: function() { console.log('mouseover'); }, mouseout: function() { console.log('mouseout'); }, click: function() { console.log('click'); } }); And when those listeners need to be removed: Ext.destroy(this.btnListeners); or this.btnListeners.destroy();

addRef ( refs )

Registers one or more references.

Parameters

refs :  Object/Object[]

applyProfiles ( profiles )
private pri

As a convenience developers can locally qualify profile names (e.g. 'MyProfile' vs 'MyApp.profile.MyProfile'). This just makes sure everything ends up fully qualified.

Parameters

profiles :  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

clearListeners

Removes all listeners for this object including the managed listeners

clearManagedListeners

Removes all managed listeners for this object.

constructor ( [config] )

Creates new Application.

Parameters

config :  Object (optional)

Config object.

control ( selectors, [listeners] )

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

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

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

     updateUser: function(button) {
         console.log('clicked the Save button');
     }
 });

Or alternatively one call control with two arguments:

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

See Ext.ComponentQuery for more information on component selectors.

Parameters

selectors :  String/Object

If a String, the second argument is used as the listeners, otherwise an object of selectors -> listeners is assumed

listeners :  Object (optional)

Config for listeners.

createController ( name ) : Ext.app.Controller

Create an instance of a controller by name.

Parameters

name :  String

The name of the controller. For a controller with the full class name `MyApp.controller.Foo`, the name parameter should be `Foo`. If the controller already exists, it will be returned.

Returns

:Ext.app.Controller
controller

createRelayer ( newName, [beginEnd] ) : Function
private pri

Creates an event handling function which re-fires the event from this object as the passed event name.

Parameters

newName :  String

The name under which to re-fire the passed parameters.

beginEnd :  Array (optional)

The caller can specify on which indices to slice.

Returns

:Function

deactivate

Prevent this controller from receiving events from the event bus. Routes will also not be triggered on inactive controllers unless the Ext.route.Route#allowInactive flag is set. Also see activate.

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.

destroyController ( controller )

Destroys a controller, any listeners are unbound.

Parameters

controller :  String/Ext.app.Controller

The controller

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.

doFireEvent ( eventName, args, bubbles )
private pri

Continue to fire event.

Parameters

eventName :  String

args :  Array

bubbles :  Boolean

enableBubble ( eventNames )

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

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

Example:

Ext.define('Ext.overrides.form.field.Base', {
    override: 'Ext.form.field.Base',

    //  Add functionality to Field's initComponent to enable the change event to bubble
    initComponent: function () {
        this.callParent();
        this.enableBubble('change');
    }
});

var myForm = Ext.create('Ext.form.Panel', {
    title: 'User Details',
    items: [{
        ...
    }],
    listeners: {
        change: function() {
            // Title goes red if form has been modified.
            myForm.header.setStyle('color', 'red');
        }
    }
});

Parameters

eventNames :  String/String[]

The event name to bubble, or an Array of event names.

fireAction ( eventName, args, fn, [scope], [options], [order] )
deprecated dep

Fires the specified event with the passed parameters and executes a function (action). By default, the action function will be executed after any "before" event handlers (as specified using the order option of addListener), but before any other handlers are fired. This gives the "before" handlers an opportunity to cancel the event by returning false, and prevent the action function from being called.

The action can also be configured to run after normal handlers, but before any "after" handlers (as specified using the order event option) by passing 'after' as the order parameter. This configuration gives any event handlers except for "after" handlers the opportunity to cancel the event and prevent the action function from being called.

Parameters

eventName :  String

The name of the event to fire.

args :  Array

Arguments to pass to handlers and to the action function.

fn :  Function

The action function.

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)

Event options for the action function. Accepts any of the options of addListener

order :  String (optional)

The order to call the action function relative too the event handlers (`'before'` or `'after'`). Note that this option is simply used to sort the action function relative to the event handlers by "priority". An order of `'before'` is equivalent to a priority of `99.5`, while an order of `'after'` is equivalent to a priority of `-99.5`. See the `priority` option of addListener for more details.

Defaults to: 'before'

Deprecated since version 5.5

fireEvent ( eventName, args ) : Boolean

Fires the specified event with the passed parameters (minus the event name, plus the options object passed to addListener).

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

Parameters

eventName :  String

The name of the event to fire.

args :  Object...

Variable number of parameters are passed to handlers.

Returns

:Boolean
returns false if any of the handlers return false otherwise it returns true.

fireEventArgs ( eventName, args ) : Boolean

Fires the specified event with the passed parameter list.

An event may be set to bubble up an Observable parent hierarchy (See Ext.Component#getBubbleTarget) by calling enableBubble.

Parameters

eventName :  String

The name of the event to fire.

args :  Object[]

An array of parameters which are passed to handlers.

Returns

:Boolean
returns false if any of the handlers return false otherwise it returns true.

fireEventedAction ( eventName, args, fn, [scope], [fnArgs] ) : Boolean

Fires the specified event with the passed parameters and executes a function (action). Evented Actions will automatically dispatch a 'before' event passing. This event will be given a special controller that allows for pausing/resuming of the event flow.

By pausing the controller the updater and events will not run until resumed. Pausing, however, will not stop the processing of any other before events.

Parameters

eventName :  String

The name of the event to fire.

args :  Array

Arguments to pass to handlers and to the action function.

fn :  Function/String

The action function.

scope :  Object (optional)

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

fnArgs :  Array/Boolean (optional)

Optional arguments for the action `fn`. If not given, the normal `args` will be used to call `fn`. If `false` is passed, the `args` are used but if the first argument is this instance it will be removed from the args passed to the action function.

Returns

:Boolean

getBubbleParent Ext.util.Observable
private pri

Gets the bubbling parent for an Observable

Returns

:Ext.util.Observable
The bubble parent. null is returned if no bubble target exists

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.

getController ( name )

Get an application's controller based on name or id. Generally, the controller id will be the same as the name unless otherwise specified.

Parameters

name :  String

The name or id of the controller you are trying to retrieve

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.

getModel ( modelName ) : Ext.Class

Returns a Ext.data.Model class with the given name.

Parameters

modelName :  String

Returns

:Ext.Class
A class ultimately derived from Ext.data.Model.

Parameters

name :  String

Returns

:String
a profile instance.

getRefMap
private pri

Returns a map of reference names to selectors

getStore ( name ) : Ext.data.Store

Returns instance of a Ext.data.Store with the given name. When store doesn't exist yet, it's created.

Parameters

name :  String

Returns

:Ext.data.Store
a store instance.

getView ( view ) : Ext.Base

Returns a View class with the given name. To create an instance of the view, you can use it like it's used by Application to create the Viewport:

this.getView('Viewport').create();

Parameters

view :  String

Returns

:Ext.Base
a view class.

hasConfig ( name )
private pri

Parameters

name :  String

hasListener ( eventName ) : Boolean

:Boolean
`true` if the event is being listened for or bubbles, else `false`

hasRef ( ref ) : Boolean

Returns true if a reference is registered.

Parameters

ref :  String

The name of the ref to check for.

Returns

:Boolean

init ( application )
template tpl

A template method that is called when your application boots. It is called before the Ext.app.Application's launch function is executed so gives a hook point to run any code before your Viewport is created.

Parameters

application :  Ext.app.Application

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

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

isActive Boolean

Checks if this controller is active. See activate & deactivate.

Returns

:Boolean
`true` if this controller is active.

isSuspended ( [event] ) : Boolean

Checks if all events, or a specific event, is suspended.

Parameters

event :  String (optional)

The name of the specific event to check

Returns

:Boolean
`true` if events are suspended

launch ( profile ) : Boolean
template tpl

Called automatically when the page has completely loaded. This is an empty function that should be overridden by each application that needs to take action on page load.

Parameters

profile :  String

The detected application profile

Returns

:Boolean
By default, the Application will dispatch to the configured startup controller and action immediately after running the launch function. Return false to prevent this behavior.

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

listen ( to, [controller] )

Adds listeners to different event sources (also called "event domains"). The primary event domain is that of components, but there are also other event domains: Ext.app.domain.Global domain that intercepts events fired from Ext.GlobalEvents Observable instance, Ext.app.domain.Controller domain can be used to listen to events fired by other Controllers, Ext.app.domain.Store domain gives access to Store events, and Ext.app.domain.Direct domain can be used with Ext Direct Providers to listen to their events.

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

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

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

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

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

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

As this relates to components, the following example:

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

Is equivalent to:

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

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

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

Parameters

to :  Object

Config object containing domains, selectors and listeners.

controller :  Ext.app.Controller (optional)

The controller to add the listeners to. Defaults to the current controller.

mon ( item, ename, [fn], [scope], [options] ) : Object

Shorthand for addManagedListener. The addManagedListener method is used when some object (call it "A") is listening to an event on another observable object ("B") and you want to remove that listener from "B" when "A" is destroyed. This is not an issue when "B" is destroyed because all of its listeners will be removed at that time.

Example:

Ext.define('Foo', {
    extend: 'Ext.Component',

    initComponent: function () {
        this.addManagedListener(MyApp.SomeGlobalSharedMenu, 'show', this.doSomething);
        this.callParent();
    }
});

As you can see, when an instance of Foo is destroyed, it ensures that the 'show' listener on the menu (MyApp.SomeGlobalSharedMenu) is also removed.

As of version 5.1 it is no longer necessary to use this method in most cases because listeners are automatically managed if the scope object provided to addListener is an Observable instance. However, if the observable instance and scope are not the same object you still need to use mon or addManagedListener if you want the listener to be managed.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item to which to add a listener/listeners.

ename :  Object/String

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

fn :  Function/String (optional)

If the `ename` parameter was an event name, this is the handler function or the name of a method on the specified scope.

scope :  Object (optional)

If the `ename` parameter was an event name, this is the scope (`this` reference) in which the handler function is executed.

options :  Object (optional)

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

Returns

:Object
**Only when the `destroyable` option is specified. ** A `Destroyable` object. An object which implements the destroy method which removes all listeners added in this call. For example: this.btnListeners = myButton.mon({ destroyable: true mouseover: function() { console.log('mouseover'); }, mouseout: function() { console.log('mouseout'); }, click: function() { console.log('click'); } }); And when those listeners need to be removed: Ext.destroy(this.btnListeners); or this.btnListeners.destroy();

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

Shorthand for removeManagedListener. Removes listeners that were added by the mon method.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item from which to remove a listener/listeners.

ename :  Object/String

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

fn :  Function (optional)

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

scope :  Object (optional)

If the `ename` parameter was an event name, this is the scope (`this` reference) in which the handler function is executed.

normalizeRefs ( refs ) : Array
private pri

Takes either an object and transforms it into an array. The following are valid refs values:

refs: {
    myComponent: 'container'
}

refs: {
    myComponent: {
        selector: 'container'
    }
}

refs: [
    {
        ref: 'myComponent',
        selector: 'container'
    }
]

Parameters

refs :  Array/Object

The refs to normalize

Returns

:Array
The normalized array of refs

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

The on method is shorthand for addListener.

Appends an event handler to this object. For example:

myGridPanel.on("itemclick", this.onItemClick, this);

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

myGridPanel.on({
    cellclick: this.onCellClick,
    select: this.onSelect,
    viewready: this.onViewReady,
    scope: this // Important. Ensure "this" is correct during handler execution
});

One can also specify options for each event handler separately:

myGridPanel.on({
    cellclick: {fn: this.onCellClick, scope: this, single: true},
    viewready: {fn: panel.onViewReady, scope: panel}
});

Names of methods in a specified scope may also be used:

myGridPanel.on({
    cellclick: {fn: 'onCellClick', scope: this, single: true},
    viewready: {fn: 'onViewReady', scope: panel}
});

Parameters

eventName :  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 (optional)

The method the event invokes or the *name* of the method within the specified scope. Will be called with arguments given to Ext.util.Observable#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. **Note:** The options object will also be passed as the last argument to every event handler. This object may contain any of the following properties:

scope :  Object

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

delay :  Number

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

single :  Boolean

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

buffer :  Number

Causes the handler to be scheduled to run in an Ext.util.DelayedTask 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.

onFrame :  Number

Causes the handler to be scheduled to run at the next animation frame event. If the event fires again before that time, the handler is not rescheduled - the handler will only be called once when the next animation frame is fired, with the last set of arguments passed.

target :  Ext.util.Observable

Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

element :  String

This option is only valid for listeners bound to Ext.Component. The name of a Component property which references an Ext.dom.Element to add a listener to.

This option is useful during Component construction to add DOM event listeners to elements of Ext.Component which will exist only after the Component is rendered.

For example, to add a click listener to a Panel's body:

  var panel = new Ext.panel.Panel({
                              title: 'The title',
                              listeners: {
                                  click: this.handlePanelClick,
                                  element: 'body'
                              }
                          });
                        

In order to remove listeners attached using the element, you'll need to reference the element itself as seen below.

 panel.body.un(...)
                        

delegate :  String (optional)

A simple selector to filter the event target or look for a descendant of the target.

The "delegate" option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

See the delegate example below.

capture :  Boolean (optional)

When set to true, the listener is fired in the capture phase of the event propagation sequence, instead of the default bubble phase.

The capture option is only available on Ext.dom.Element instances (or when attaching a listener to a Ext.dom.Element via a Component using the element option).

stopPropagation :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopPropagation on the event object before firing the handler.

preventDefault :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call preventDefault on the event object before firing the handler.

stopEvent :  Boolean (optional)

This option is only valid for listeners bound to Ext.dom.Element. true to call stopEvent on the event object before firing the handler.

args :  Array (optional)

Optional arguments to pass to the handler function. Any additional arguments passed to fireEvent will be appended to these arguments.

destroyable :  Boolean (optional)

When specified as true, the function returns a destroyable object. An object which implements the destroy method which removes all listeners added in this call. This syntax can be a helpful shortcut to using un; particularly when removing multiple listeners. NOTE - not compatible when using the element option. See un for the proper syntax for removing listeners added using the element config.

Defaults to:

false

priority :  Number (optional)

An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handlers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code. A priority must be an integer to be valid. Fractional values are reserved for internal framework use.

order :  String (optional)

A legacy option that is provided for backward compatibility. It is recommended to use the priority option instead. Available options are:

  • 'before': equal to a priority of 100
  • 'current': equal to a priority of 0 or default priority
  • 'after': equal to a priority of -100

Defaults to:

'current'

order :  String (optional)

A shortcut for the `order` event option. Provided for backward compatibility. Please use the `priority` event option instead. **Combining Options** Using the options argument, it is possible to combine different types of listeners: A delayed, one-time listener. myPanel.on('hide', this.handleClick, 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 handlers and handler configs. grid.on({ itemclick: 'onItemClick', itemcontextmenu: grid.onItemContextmenu, destroy: { fn: function () { // function called within the 'altCmp' scope instead of grid }, scope: altCmp // unique scope for the destroy handler }, scope: grid // default scope - provided for example clarity }); **Delegate** This is a configuration option that you can pass along when registering a handler for an event to assist with event delegation. By setting this configuration option to a simple selector, the target element will be filtered to look for a descendant of the target. For example: var panel = Ext.create({ xtype: 'panel', renderTo: document.body, title: 'Delegate Handler Example', frame: true, height: 220, width: 220, html: '

BODY TITLE

Body content' }); // The click handler will only be called when the click occurs on the // delegate: h1.myTitle ("h1" tag with class "myTitle") panel.on({ click: function (e) { console.log(e.getTarget().innerHTML); }, element: 'body', delegate: 'h1.myTitle' });

Defaults to: 'current'

Returns

:Object
**Only when the `destroyable` option is specified. ** A `Destroyable` object. An object which implements the destroy method which removes all listeners added in this call. For example: this.btnListeners = = myButton.on({ destroyable: true mouseover: function() { console.log('mouseover'); }, mouseout: function() { console.log('mouseout'); }, click: function() { console.log('click'); } }); And when those listeners need to be removed: Ext.destroy(this.btnListeners); or this.btnListeners.destroy();

onAfter ( 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.

onAppUpdate ( [updateInfo] )
template tpl

Called automatically when an update to either the Application Cache or the Local Storage Cache is detected. This is mainly used during production builds.

Parameters

updateInfo :  Object (optional)

updateInfo Update information object contains properties for checking which cache triggered the update

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

onBefore ( 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.

onLaunch ( application )
template tpl

A template method like init, but called after the viewport is created. This is called after the launch method of Application is executed.

Parameters

application :  Ext.app.Application

This is a template method. a hook into the functionality of this class. Feel free to override it in child classes.

redirectTo ( hash, opt ) : Boolean

Update the hash. By default, it will not execute the routes if the current token and the token passed are the same.

Parameters

hash :  String/Number/Object/Ext.data.Model

The hash to redirect to. The hash can be of several values: - **String** The hash to exactly be set to. - **Number** If `1` is passed, forward function will be executed. If `-1` is passed, back function will be executed. - **Ext.data.Model** If a model instance is passed, the Model's toUrl function will be executed to convert it into a String value to set the hash to. - **Object** An Object can be passed to control individual tokens in the full hash. They key should be an associated Ext.route.Routes name and the value should be the value of that token in the complete hash. For example, if you have two routes configured, each token in the hash that can be matched for each route can be individually controlled: routes: { 'foo/bar': 'onFooBar', 'baz/:id': { action: 'onBaz', name: 'baz' } } If you pass in a hash of `#foo/bar|baz/1`, each route will exeucte in response. If you want to change only the `baz` route but leave the `foo/bar` route in the hash, you can pass only the `baz` key in an object: this.redirectTo({ baz : 'baz/5' }); and the resulting hash will be `#foo/bar/|baz/5` and only the `baz` route will execute in reaction but the `foo/bar` will not react since it's associated token in the hash remained the same. If you wanted to update the `baz` route and remove `foo/bar` from the hash, you can set the value to `null`: this.redirectTo({ 'foo/bar': null, baz: 'baz/3' }); and the resulting hash will be `#baz/3`. Like before, the `baz` route will execute in reaction.

opt :  Object

An optional Object describing how to enact the hash being passed in. Valid options are: - `force` Even if the hash will not change, setting this to `true` will force the Ext.route.Router to react. - `replace` When set to `true`, this will replace the current resource in the history stack with the hash being set. For backwards compatibility, if `true` is passed instead of an Object, this will set the `force` option to `true`.

Returns

:Boolean
Will return `true` if the token was updated.

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

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

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

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

The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword (unless the event is handled by a controller's control/listen event listener in which case 'this' will be the controller rather than the grid).

Parameters

origin :  Object

The Observable whose events this object is to relay.

events :  String[]/Object

Array of event names to relay or an Object with key/value pairs translating to ActualEventName/NewEventName respectively. For example: this.relayEvents(this, {add:'push', remove:'pop'}); Would now redispatch the add event of this as a push event and the remove event as a pop event.

prefix :  String (optional)

A common prefix to prepend to the event names. For example: this.relayEvents(this.getStore(), ['load', 'clear'], 'store'); Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.

Returns

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

removeListener ( eventName, fn, [scope] ) :
chainable ch

Removes an event handler.

Parameters

eventName :  String

The type of event the handler was associated with.

fn :  Function

The handler to remove. **This must be a reference to the function passed into the addListener call.**

scope :  Object (optional)

The scope originally specified for the handler. It must be the same as the scope argument specified in the original call to Ext.util.Observable#addListener or the listener will not be removed. **Convenience Syntax** You can use the addListener `destroyable: true` config option in place of calling un(). For example: var listeners = cmp.on({ scope: cmp, afterrender: cmp.onAfterrender, beforehide: cmp.onBeforeHide, destroyable: true }); // Remove listeners listeners.destroy(); // or cmp.un( scope: cmp, afterrender: cmp.onAfterrender, beforehide: cmp.onBeforeHide ); **Exception - DOM event handlers using the element config option** You must go directly through the element to detach an event handler attached using the addListener _element_ option. panel.on({ element: 'body', click: 'onBodyCLick' }); panel.body.un({ click: 'onBodyCLick' });

Returns

:

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

Removes listeners that were added by the mon method.

Parameters

item :  Ext.util.Observable/Ext.dom.Element

The item from which to remove a listener/listeners.

ename :  Object/String

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

fn :  Function (optional)

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

scope :  Object (optional)

If the `ename` parameter was an event name, this is the scope (`this` reference) in which the handler function is executed.

removeManagedListenerItem ( isClear, managedListener )
private pri

Remove a single managed listener item

Parameters

isClear :  Boolean

True if this is being called during a clear

managedListener :  Object

resolveListenerScope ( [defaultScope] ) : Object
protected pro

Gets the default scope for firing late bound events (string names with no scope attached) at runtime.

Parameters

defaultScope :  Object (optional)

The default scope to return if none is found.

Defaults to: this

Returns

The default event scope

resumeEvent ( eventName )

Resumes firing of the named event(s).

After calling this method to resume events, the events will fire when requested to fire.

Note that if the suspendEvent method is called multiple times for a certain event, this converse method will have to be called the same number of times for it to resume firing.

Parameters

eventName :  String...

Multiple event names to resume.

resumeEvents ( [discardQueue] )

Resumes firing events (see suspendEvents).

If events were suspended using the queueSuspended parameter, then all events fired during event suspension will be sent to any listeners now.

Parameters

discardQueue :  Boolean (optional)

`true` to prevent any previously queued events from firing while we were suspended. See suspendEvents.

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();

        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

        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

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.

Note that if this is called multiple times for a certain event, the converse method resumeEvent will have to be called the same number of times for it to resume firing.

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.

un ( eventName, fn, [scope] ) :

Shorthand for removeListener. Removes an event handler.

Parameters

eventName :  String

The type of event the handler was associated with.

fn :  Function

The handler to remove. **This must be a reference to the function passed into the addListener call.**

scope :  Object (optional)

The scope originally specified for the handler. It must be the same as the scope argument specified in the original call to Ext.util.Observable#addListener or the listener will not be removed. **Convenience Syntax** You can use the addListener `destroyable: true` config option in place of calling un(). For example: var listeners = cmp.on({ scope: cmp, afterrender: cmp.onAfterrender, beforehide: cmp.onBeforeHide, destroyable: true }); // Remove listeners listeners.destroy(); // or cmp.un( scope: cmp, afterrender: cmp.onAfterrender, beforehide: cmp.onBeforeHide ); **Exception - DOM event handlers using the element config option** You must go directly through the element to detach an event handler attached using the addListener _element_ option. panel.on({ element: 'body', click: 'onBodyCLick' }); panel.body.un({ click: 'onBodyCLick' });

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
