Ext.tab.Panelxtype: tabpanel

Hierarchy

Mixins

A basic tab container. TabPanels can be used exactly like a standard Ext.panel.Panel for layout purposes, but also have special support for containing child Components (items) that are managed using a CardLayout layout manager, and displayed as separate tabs.

Note:

By default, a tab's close tool destroys the child tab Component and all its descendants. This makes the child tab Component, and all its descendants unusable. To enable re-use of a tab, configure the TabPanel with autoDestroy: false.

TabPanel's layout:

TabPanels use a Dock layout to position the TabBar at the top of the widget. Panels added to the TabPanel will have their header hidden by default because the Tab will automatically take the Panel's configured title and icon.

TabPanels use their header or footer element (depending on the tabPosition configuration) to accommodate the tab selector buttons. This means that a TabPanel will not display any configured title, and will not display any configured header tools.

To display a header, embed the TabPanel in a Panel which uses layout:'fit'.

Examples:

Here is a basic TabPanel rendered to the body. This also shows the useful configuration activeTab, which allows you to set the active tab on render. If you do not set an activeTab, no tabs will be active by default. TabPanel component Example usage:

Ext.create('Ext.tab.Panel', {
    width: 300,
    height: 200,
    activeTab: 0,
    items: [
        {
            title: 'Tab 1',
            bodyPadding: 10,
            html : 'A simple tab'
        },
        {
            title: 'Tab 2',
            html : 'Another one'
        }
    ],
    renderTo : Ext.getBody()
}); 

It is easy to control the visibility of items in the tab bar. Specify hidden: true to have the tab button hidden initially. Items can be subsequently hidden and show by accessing the tab property on the child item.

Example usage:

var tabs = Ext.create('Ext.tab.Panel', {
    width: 400,
    height: 400,
    renderTo: document.body,
    items: [{
        title: 'Home',
        html: 'Home',
        itemId: 'home'
    }, {
        title: 'Users',
        html: 'Users',
        itemId: 'users',
        hidden: true
    }, {
        title: 'Tickets',
        html: 'Tickets',
        itemId: 'tickets'
    }]    
});

setTimeout(function(){
    tabs.child('#home').tab.hide();
    var users = tabs.child('#users');
    users.tab.show();
    tabs.setActiveTab(users);
}, 1000);

You can remove the background of the TabBar by setting the plain property to false.

Example usage:

Ext.create('Ext.tab.Panel', {
    width: 300,
    height: 200,
    activeTab: 0,
    plain: true,
    items: [
        {
            title: 'Tab 1',
            bodyPadding: 10,
            html : 'A simple tab'
        },
        {
            title: 'Tab 2',
            html : 'Another one'
        }
    ],
    renderTo : Ext.getBody()
}); 

Another useful configuration of TabPanel is tabPosition. This allows you to change the position where the tabs are displayed. The available options for this are 'top' (default) and 'bottom'. TabPanel component Example usage:

Ext.create('Ext.tab.Panel', {
    width: 300,
    height: 200,
    activeTab: 0,
    bodyPadding: 10,        
    tabPosition: 'bottom',
    items: [
        {
            title: 'Tab 1',
            html : 'A simple tab'
        },
        {
            title: 'Tab 2',
            html : 'Another one'
        }
    ],
    renderTo : Ext.getBody()
}); 

The setActiveTab is a very useful method in TabPanel which will allow you to change the current active tab. You can either give it an index or an instance of a tab.

Example usage:

var tabs = Ext.create('Ext.tab.Panel', {
    items: [
        {
            id   : 'my-tab',
            title: 'Tab 1',
            html : 'A simple tab'
        },
        {
            title: 'Tab 2',
            html : 'Another one'
        }
    ],
    renderTo : Ext.getBody()
});

var tab = Ext.getCmp('my-tab');

Ext.create('Ext.button.Button', {
    renderTo: Ext.getBody(),
    text    : 'Select the first tab',
    scope   : this,
    handler : function() {
        tabs.setActiveTab(tab);
    }
});

Ext.create('Ext.button.Button', {
    text    : 'Select the second tab',
    scope   : this,
    handler : function() {
        tabs.setActiveTab(1);
    },
    renderTo : Ext.getBody()        
});

The getActiveTab is a another useful method in TabPanel which will return the current active tab.

Example usage:

var tabs = Ext.create('Ext.tab.Panel', {
    items: [
        {
            title: 'Tab 1',
            html : 'A simple tab'
        },
        {
            title: 'Tab 2',
            html : 'Another one'
        }
    ],
    renderTo : Ext.getBody()        
});

Ext.create('Ext.button.Button', {
    text    : 'Get active tab',
    scope   : this,
    handler : function() {
        var tab = tabs.getActiveTab();
        alert('Current tab: ' + tab.title);
    },
    renderTo : Ext.getBody()        
});

Adding a new tab is very simple with a TabPanel. You simple call the add method with an config object for a panel.

Example usage:

var tabs = Ext.Create('Ext.tab.Panel', {
    items: [
        {
            title: 'Tab 1',
            html : 'A simple tab'
        },
        {
            title: 'Tab 2',
            html : 'Another one'
        }
    ],
    renderTo : Ext.getBody()        
});

Ext.create('Ext.button.Button', {
    text    : 'New tab',
    scope   : this,
    handler : function() {
        var tab = tabs.add({
            title: 'Tab ' + (tabs.items.length + 1), //we use the tabs.items property to get the length of current items/tabs
            html : 'Another one'
        });

        tabs.setActiveTab(tab);
    },
    renderTo : Ext.getBody()
});

Additionally, removing a tab is very also simple with a TabPanel. You simple call the remove method with an config object for a panel.

Example usage:

var tabs = Ext.Create('Ext.tab.Panel', {        
    items: [
        {
            title: 'Tab 1',
            html : 'A simple tab'
        },
        {
            id   : 'remove-this-tab',
            title: 'Tab 2',
            html : 'Another one'
        }
    ],
    renderTo : Ext.getBody()
});

Ext.Create('Ext.button.Button', {
    text    : 'Remove tab',
    scope   : this,
    handler : function() {
        var tab = Ext.getCmp('remove-this-tab');
        tabs.remove(tab);
    },
    renderTo : Ext.getBody()
});

A tag name or DomHelper spec used to create the Element which will encapsulate this Component.

You do not normally need to specify this. For the base classes Ext.Component and Ext.container.Container, this defaults to 'div'. The more complex Sencha classes use a more complex DOM structure specified by their own renderTpls.

This is intended to allow the developer to create application-specific utility Components encapsulated by different DOM elements. Example usage:

{
    xtype: 'component',
    autoEl: {
        tag: 'img',
        src: 'http://www.example.com/example.jpg'
    }
}, {
    xtype: 'component',

True to display the 'close' tool button and allow the user to close the window, false to hide the button and disallow closing the window (defaults to false).

By default, when close is requested by clicking the close button in the header, the close method will be called. This will destroy the Panel and its content meaning that it may not be reused.

To make closing a Panel hide the Panel so that it may be reused, set closeAction to 'hide'.

The action to take when the close header tool is clicked:

  • 'destroy' : Default
    remove the window from the DOM and destroy it and all descendant Components. The window will not be available to be redisplayed via the show method.
  • 'hide' :
    hide the window by setting visibility to hidden and applying negative offsets. The window will be available to be redisplayed via the show method.

Note: This behavior has changed! setting *does* affect the close method which will invoke the approriate closeAction.

Important: this config is only effective for collapsible Panels which are direct child items of a border layout.

When not a direct child item of a border layout, then the Panel's header remains visible, and the body is collapsed to zero dimensions. If the Panel has no header, then a new header (orientated correctly depending on the collapseDirection) will be inserted to show a the title and a re-expand tool.

When a child item of a border layout, this config has two options:

  • undefined/omitted
    When collapsed, a placeholder Header is injected into the layout to represent the Panel and to provide a UI with a Tool to allow the user to re-expand the Panel.
  • header :
    The Panel collapses to leave its header visible as when not inside a border layout.

The sizing and positioning of a Component's internal Elements is the responsibility of the Component's layout manager which sizes a Component's internal structure in response to the Component being sized.

Generally, developers will not use this configuration as all provided Components which need their internal elements sizing (Such as input fields) come with their own componentLayout managers.

The default layout manager will be used on instances of the base Ext.Component class which simply sizes the Component's encapsulating element to the height and width specified in the setSize method.

Optional. Specify an existing HTML element, or the id of an existing HTML element to use as the content for this component.

  • Description :
    This config option is used to take an existing HTML element and place it in the layout element of a new component (it simply moves the specified DOM element after the Component is rendered to use as the content.
  • Notes :
    The specified HTML element is appended to the layout element of the component after any configured HTML has been inserted, and so the document will not contain this element at the time the render event is fired.
    The specified HTML element used will not participate in any layout scheme that the Component may use. It is just HTML. Layouts operate on child items.
    Add either the x-hidden or the x-hide-display CSS class to prevent a brief flicker of the content before it is rendered to the panel.

Defaults to 'panel'.

This option is a means of applying default settings to all added items whether added through the items config or via the add or insert methods.

If an added item is a config object, and not an instantiated Component, then the default properties are unconditionally applied. If the added item is an instantiated Component, then the default properties are applied conditionally so as not to override existing properties in the item.

If the defaults option is specified as a function, then the function will be called using this Container as the scope (this reference) and passing the added item as the first parameter. Any resulting object from that call is then applied to the item as default properties.

For example, to automatically apply padding to the body of each of a set of contained Ext.panel.Panel items, you could pass: defaults: {bodyStyle:'padding:15px'}.

Usage:

defaults: {               // defaults are applied to items, not the container
    autoScroll:true
},
items: [
    {
        xtype: 'panel',   // defaults do not have precedence over
        id: 'panel1',     // options in config objects, so the defaults
        autoScroll: false // will not be applied here, panel1 will be autoScroll:false
    },
    new Ext.panel.Panel({       // defaults do have precedence over options
        id: 'panel2',     // options in components, so the defaults
        autoScroll: false // will be applied here, panel2 will be autoScroll:true.
    })
]

true by default to defer the rendering of child items to the browsers DOM until a tab is activated. false will render all contained items as soon as the layout is rendered. If there is a significant amount of content or a lot of heavy controls being rendered into panels that are not displayed by default, setting this to true might improve performance.


The deferredRender property is internally passed to the layout manager for

TabPanels (Ext.layout.container.Card) as its Ext.layout.container.Card.deferredRender configuration value.


Note: leaving deferredRender as true means that the content

within an unactivated tab will not be available

 

Defaults to false.

A component or series of components to be added as docked items to this panel. The docked items can be docked to either the top, right, left or bottom of a panel. This is typically used for things like toolbars or tab bars:

var panel = new Ext.panel.Panel({
    dockedItems: [{
        xtype: 'toolbar',
        dock: 'top',
        items: [{
            text: 'Docked to the top'
        }]
    }]
});

Specify as true to make a floating Component draggable using the Component's encapsulating element as the drag handle.

This may also be specified as a config object for the ComponentDragger which is instantiated to perform dragging.

For example to create a Component which may only be dragged around using a certain internal element as the drag handle, use the delegate option:

new Ext.Component({
    constrain: true,
    floating:true,
    style: {
        backgroundColor: '#fff',
        border: '1px solid black'
    },
    html: '<h1 style="cursor:move">The title</h1><p>The content</p>',
    draggable: {
        delegate: 'h1'
    }
}).show();

Specify as true to float the Component outside of the document flow using CSS absolute positioning.

Components such as Windows and Menus are floating by default.

Floating Components that are programatically rendered will register themselves with the global ZIndexManager

Floating Components as child items of a Container

A floating Component may be used as a child item of a Container. This just allows the floating Component to seek a ZIndexManager by examining the ownerCt chain.

When configured as floating, Components acquire, at render time, a ZIndexManager which manages a stack of related floating Components. The ZIndexManager brings a single floating Component to the top of its stack when the Component's toFront method is called.

The ZIndexManager is found by traversing up the ownerCt chain to find an ancestor which itself is floating. This is so that descendant floating Components of floating Containers (Such as a ComboBox dropdown within a Window) can have its zIndex managed relative to any siblings, but always above that floating ancestor Container.

If no floating ancestor is found, a floating Component registers itself with the default ZIndexManager.

Floating components do not participate in the Container's layout. Because of this, they are not rendered until you explicitly show them.

After rendering, the ownerCt reference is deleted, and the floatParent property is set to the found floating ancestor Container. If no floating ancestor Container was found the floatParent property will not be set.

An HTML fragment, or a DomHelper specification to use as the layout element content (defaults to '').

The unique id of this component instance (defaults to an auto-assigned id).

It should not be necessary to use this configuration except for singleton objects in your application. Components created with an id may be accessed globally using Ext.getCmp.

Instead of using assigned ids, use the itemId config, and ComponentQuery which provides selector-based searching for Sencha Components analogous to DOM querying. The Container class contains shortcut methods to query its descendant Components by selector.

Note that this id will also be used as the element id for the containing HTML element that is rendered to the page for this component. This allows you to write id-based CSS rules to style the specific instance of this component uniquely, and also to select sub-elements using this component's id as the parent.

Note: to avoid complications imposed by a unique id also see itemId.

Note: to access the container of a Component see ownerCt.

An itemId can be used as an alternative way to get a reference to a component when no object reference is available. Instead of using an id with Ext.getCmp, use itemId with Ext.container.Container.getComponent which will retrieve itemId's or id's. Since itemId's are an index to the container's internal MixedCollection, the itemId is scoped locally to the container -- avoiding potential conflicts with Ext.ComponentManager which requires a unique id.

var c = new Ext.panel.Panel({ //
    height: 300,
    renderTo: document.body,
    layout: 'auto',
    items: [
        {
            itemId: 'p1',
            title: 'Panel 1',
            height: 150
        },
        {
            itemId: 'p2',
            title: 'Panel 2',
            height: 150
        }
    ]
})
p1 = c.getComponent('p1'); // not the same as Ext.getCmp()
p2 = p1.ownerCt.getComponent('p2'); // reference via a sibling

Also see id, query, down and child.

Note: to access the container of an item see ownerCt.

A single item, or an array of child Components to be added to this container

Unless configured with a layout, a Container simply renders child Components serially into its encapsulating element and performs no sizing or positioning upon them.

Example:

// specifying a single item
items: {...},
layout: 'fit',    // The single items is sized to fit

// specifying multiple items
items: [{...}, {...}],
layout: 'hbox', // The items are arranged horizontally
       

Each item may be:

  • A Component
  • A Component configuration object

If a configuration object is specified, the actual type of Component to be instantiated my be indicated by using the xtype option.

Every Component class has its own xtype.

If an xtype is not explicitly specified, the defaultType for the Container is used, which by default is usually panel.

Notes:

Ext uses lazy rendering. Child Components will only be rendered should it become necessary. Items are automatically laid out when they are first shown (no sizing is done while hidden), or in response to a doLayout call.

Do not specify contentEl or html with items.

(optional)

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 ExtJs Components


While some ExtJs 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 click 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'); }
        }
    }
});

An object containing properties specifying DomQuery selectors which identify child elements created by the render process.

After the Component's internal structure is rendered according to the renderTpl, this object is iterated through, and the found Elements are added as properties to the Component using the renderSelector property name.

For example, a Component which rendered an image, and description into its element might use the following properties coded into its prototype:

renderTpl: '&lt;img src="{imageUrl}" class="x-image-component-img">&lt;div class="x-image-component-desc">{description}&gt;/div&lt;',

renderSelectors: {
    image: 'img.x-image-component-img',
    descEl: 'div.x-image-component-desc'
}

After rendering, the Component would have a property image referencing its child img Element, and a property descEl referencing the div Element which contains the description.

  • Notes :
      Do not use this option if the Component is to be a child item of a Container. It is the responsibility of the Container's layout manager to render and manage its child items.
      When using this config, a call to render() is not required.

See render also.

An XTemplate used to create the internal structure inside this Component's encapsulating Element.

You do not normally need to specify this. For the base classes Ext.Component and Ext.container.Container, this defaults to null which means that they will be initially rendered with no internal structure; they render their Element empty. The more specialized ExtJS and Touch classes which use a more complex DOM structure, provide their own template definitions.

This is intended to allow the developer to create application-specific utility Components with customized internal structure.

Upon rendering, any created child elements may be automatically imported into object properties using the renderSelectors option.

A flag which causes the object to attempt to restore the state of internal properties from a saved state on startup. The object must have a stateId for state to be managed. Auto-generated ids are not guaranteed to be stable across page loads and cannot be relied upon to save and restore the same state for a object.

For state saving to work, the state manager's provider must have been set to an implementation of Ext.state.Provider which overrides the set and get methods to save and recall name/value pairs. A built-in implementation, Ext.state.CookieProvider is available.

To set the state provider for the current page:

Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
    expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now
}));

A stateful object attempts to save state when one of the events listed in the stateEvents configuration fires.

To save state, a stateful object first serializes its state by calling getState. By default, this function does nothing. The developer must provide an implementation which returns an object hash which represents the restorable state of the object.

The value yielded by getState is passed to Ext.state.Manager.set which uses the configured Ext.state.Provider to save the object keyed by the stateId

.

During construction, a stateful object attempts to restore its state by calling Ext.state.Manager.get passing the stateId

The resulting object is passed to applyState. The default implementation of applyState simply copies properties into the object, but a developer may override this to support more behaviour.

You can perform extra processing on state save and restore by attaching handlers to the beforestaterestore, staterestore, beforestatesave and statesave events.

Optional. Only present for floating Components which were inserted as descendant items of floating Containers.

Floating Components that are programatically rendered will not have a floatParent property.

For floating Components which are child items of a Container, the floatParent will be the floating ancestor Container which is responsible for the base z-index value of all its floating descendants. It provides a ZIndexManager which provides z-indexing services for all its descendant floating Components.

Optional. Only present for floating Components after they have been rendered.

A reference to the ZIndexManager which is managing this Component's z-index.

The ZIndexManager maintains a stack of floating Component z-indices, and also provides a single modal mask which is insert just beneath the topmost visible modal floating Component.

Floating Components may be brought to the front or sent to the back of the z-index stack.

This defaults to the global ZIndexManager for floating Components that are programatically rendered.

For floating Components which are added to a Container, the ZIndexManager is acquired from the first ancestor Container found which is floating, or if not found the global ZIndexManager is used.

Adds Component(s) to this Container.

Description:

Notes:

If the Container is already rendered when add is called, it will render the newly added Component into its content area.

If the Container was configured with a size-managing layout manager, the Container will recalculate its internal layout at this time too.

Note that the default layout manager simply renders child Components sequentially into the content area and thereafter performs no sizing.

If adding multiple new child Components, pass them as an array to the add method, so that only one layout recalculation is performed.

tb = new Ext.toolbar.Toolbar({
    renderTo: document.body
});  // toolbar is rendered
tb.add([{text:'Button 1'}, {text:'Button 2'}]); // add multiple items. (defaultType for Toolbar is 'button')

Warning:##

Components directly managed by the BorderLayout layout manager may not be removed or added. See the Notes for BorderLayout for more details.

addListener( String eventName, Function handler, [Object scope], [Object options]) : void

Appends an event handler to this object.

Appends an event handler to this object.

Parameters

  • eventName : String

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

  • handler : Function

    The method the event invokes.

  • 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. properties. This 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.
    • target : 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 Components. The name of a Component property which references an element to add a listener to.

      This option is useful during Component construction to add DOM event listeners to elements of Components which will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:

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

      When added in this way, the options available are the options applicable to Ext.core.Element.addListener


    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 events. For example:

    myGridPanel.on({
        cellClick: this.onCellClick,
        mouseover: this.onMouseOver,
        mouseout: this.onMouseOut,
        scope: this // Important. Ensure "this" is correct during handler execution
    });
    
    .

Returns

  • void

Perform custom animation on this object.

This method is applicable to both the the Component class and the Element class. It performs animated transitions of certain properties of this object over a specified timeline.

The sole parameter is an object which specifies start property values, end property values, and properties which describe the timeline. Of the properties listed below, only to is mandatory.

Properties include

  • from
    An object which specifies start values for the properties being animated. If not supplied, properties are animated from current settings. The actual properties which may be animated depend upon ths object being animated. See the sections below on Element and Component animation.
  • to
    An object which specifies end values for the properties being animated.
  • duration
    The duration in milliseconds for which the animation will run.
  • easing
    A string value describing an easing type to modify the rate of change from the default linear to non-linear. Values may be one of:
    • ease
    • easeIn
    • easeOut
    • easeInOut
    • backIn
    • backOut
    • elasticIn
    • elasticOut
    • bounceIn
    • bounceOut
  • keyframes
    This is an object which describes the state of animated properties at certain points along the timeline. it is an object containing properties who's names are the percentage along the timeline being described and who's values specify the animation state at that point.
  • listeners
    This is a standard listeners configuration object which may be used to inject behaviour at either the beforeanimate event or the afteranimate event.

Animating an Element

When animating an Element, the following properties may be specified in from, to, and keyframe objects:
  • x
    The page X position in pixels.
  • y
    The page Y position in pixels
  • left
    The element's CSS left value. Units must be supplied.
  • top
    The element's CSS top value. Units must be supplied.
  • width
    The element's CSS width value. Units must be supplied.
  • height
    The element's CSS height value. Units must be supplied.
  • scrollLeft
    The element's scrollLeft value.
  • scrollTop
    The element's scrollLeft value.
  • opacity
    The element's opacity value. This must be a value between 0 and 1.

Be aware than animating an Element which is being used by an Ext Component without in some way informing the Component about the changed element state will result in incorrect Component behaviour. This is because the Component will be using the old state of the element. To avoid this problem, it is now possible to directly animate certain properties of Components.

Animating a Component

When animating an Element, the following properties may be specified in from, to, and keyframe objects:
  • x
    The Component's page X position in pixels.
  • y
    The Component's page Y position in pixels
  • left
    The Component's left value in pixels.
  • top
    The Component's top value in pixels.
  • width
    The Component's width value in pixels.
  • width
    The Component's width value in pixels.
  • dynamic
    Specify as true to update the Component's layout (if it is a Container) at every frame of the animation. Use sparingly as laying out on every intermediate size change is an expensive operation.

For example, to animate a Window to a new size, ensuring that its internal layout, and any shadow is correct:

myWindow = Ext.create('Ext.window.Window', {
    title: 'Test Component animation',
    width: 500,
    height: 300,
    layout: {
        type: 'hbox',
        align: 'stretch'
    },
    items: [{
        title: 'Left: 33%',
        margins: '5 0 5 5',
        flex: 1
    }, {
        title: 'Left: 66%',
        margins: '5 5 5 5',
        flex: 2
    }]
});
myWindow.show();
myWindow.header.el.on('click', function() {
    myWindow.animate({
        to: {
            width: (myWindow.getWidth() == 500) ? 700 : 500,
            height: (myWindow.getHeight() == 300) ? 400 : 300,
        }
    });
});

For performance reasons, by default, the internal layout is only updated when the Window reaches its final "to" size. If dynamic updating of the Window's child Components is required, then configure the animation with dynamic: true and the two child items will maintain their proportions during the animation.

Parameters

  • config : Object

    An object containing properties which describe the animation's start and end states, and the timeline of the animation.

Returns

  • Object

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present....

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.override(Ext.form.field.Base, {
//  Add functionality to Field's initComponent to enable the change event to bubble
initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
    this.enableBubble('change');
}),

//  We know that we want Field's events to bubble directly to the FormPanel.
getBubbleTarget : function() {
    if (!this.formPanel) {
        this.formPanel = this.findParentByType('form');
    }
    return this.formPanel;
}
});

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

Parameters
