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.
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'.
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 CSS class, space-delimited string of classes, or array of classes to be applied to the panel's body element. The following examples are all valid:
bodyCls: 'foo'
bodyCls: 'foo bar'
bodyCls: ['foo', 'bar']
An optional extra CSS class that will be added to this component's Element (defaults to ''). This can be useful for adding customized styles to the component or any of its children using standard CSS rules.

The class added to each child item of this TabPanel. Defaults to 'x-tabpanel-child'.
An optional extra CSS class that will be added to this component's Element when the mouse moves over the Element, and removed when the mouse moves out. (defaults to ''). This can be useful for adding customized 'active' or 'hover' styles to the component or any of its children using standard CSS rules.
The class that is added to the content target when you set styleHtmlContent to true. Defaults to 'x-html'
The class that is added to the content target when you set styleHtmlContent to true. Defaults to 'x-html'
Other Configs
plain True to not show the full background on the TabBar
plain True to not show the full background on the TabBar
A string component id or the numeric index of the component that should be initially activated within the container's layout on render. For example, activeItem: 'item-1' or activeItem: 0 (index 0 = the first item in the container's collection). activeItem only applies to layout styles that can display items one at a time (like Ext.layout.container.Card and Ext.layout.container.Fit).
true to animate the transition when the panel is collapsed, false to skip the
animation (defaults to true if the Ext.fx.Anim class is available, otherwise false).
May also be specified as the animation duration in milliseconds.
If true the container will automatically destroy any contained component that is removed from it, else destruction must be handled manually. Defaults to true.
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',
autoEl: {
tag: 'blockquote',
html: 'autoEl is cool!'
}
}, {
xtype: 'container',
autoEl: 'ul',
cls: 'ux-unordered-list',
items: {
xtype: 'component',
autoEl: 'li',
html: 'First list item'
}
}
This config is intended mainly for floating Components which may or may not be shown. Instead of using renderTo in the configuration, and rendering upon construction, this allows a Component to render itself upon first show.
Specify as true to have this Component render to the document body upon first show.
Specify as an element, or the ID of an element to have this Component render to a specific element upon first show.
This defaults to true for the Window class.
true to use overflow:'auto' on the components layout element and show scroll bars automatically when
necessary, false to clip any overflowing content (defaults to false).
True to automatically show the component upon creation. This config option may only be used for floating components or components that use autoRender. Defaults to false.
The base CSS class to apply to this panel's element (defaults to 'x-panel').
The base CSS class to apply to this panel's element (defaults to 'x-panel').
Convenience method. Short for 'Bottom Bar'.
bbar: [
{ xtype: 'button', text: 'Button 1' }
]
is equivalent to
dockedItems: [{
xtype: 'toolbar',
dock: 'bottom',
items: [
{ xtype: 'button', text: 'Button 1' }
]
}]
A shortcut to add or remove the border on the body of a panel. This only applies to a panel which has the frame configuration set to true.
Defaults to undefined.
A CSS class, space-delimited string of classes, or array of classes to be applied to the panel's body element. The following examples are all valid:
bodyCls: 'foo'
bodyCls: 'foo bar'
bodyCls: ['foo', 'bar']
A shortcut for setting a padding style on the body element. The value can either be
a number to be applied to all sides, or a normal css string describing padding.
Defaults to undefined.
Custom CSS styles to be applied to the panel's body element, which can be supplied as a valid CSS style string, an object containing style property name/value pairs or a function that returns such a string or object. For example, these two formats are interpreted to be equivalent:
bodyStyle: 'background:#ffc; padding:10px;'
bodyStyle: {
background: '#ffc',
padding: '10px'
}
Specifies the border for this component. The border can be a single numeric value to apply to all sides or it can be a CSS style specification for each style, for example: '10 5 3 10'.
An array of events that, when fired, should be bubbled to any parent container.
See Ext.util.Observable.enableBubble.
Defaults to ['add', 'remove'].
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:
Note: This behavior has changed! setting *does* affect the close method which will invoke the approriate closeAction.
An optional extra CSS class that will be added to this component's Element (defaults to ''). This can be useful for adding customized styles to the component or any of its children using standard CSS rules.
The direction to collapse the Panel when the toggle button is clicked.
Defaults to the headerPosition
Important: This config is ignored for collapsible Panels which are direct child items of a border layout.
Specify as 'top', 'bottom', 'left' or 'right'.
true to make sure the collapse/expand toggle button always renders first (to the left of)
any other tools in the panel's title bar, false to render it last (defaults to true).
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/omittedWhen 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.
true to render the panel collapsed, false to render it expanded (defaults to
false).
true to render the panel collapsed, false to render it expanded (defaults to
false).
A CSS class to add to the panel's element after it has been collapsed (defaults to
'collapsed').
A CSS class to add to the panel's element after it has been collapsed (defaults to
'collapsed').
True to make the panel collapsible and have an expand/collapse toggle Tool added into the header tool button area. False to keep the panel sized either statically, or by an owning layout manager, with no toggle Tool (defaults to false).
See collapseMode and collapseDirection
CSS Class to be added to a components root level element to give distinction to it via styling.
CSS Class to be added to a components root level element to give distinction to it via styling.
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
layoutscheme that the Component may use. It is just HTML. Layouts operate on childitems.Add either thex-hiddenor thex-hide-displayCSS class to prevent a brief flicker of the content before it is rendered to the panel.
The default xtype of child Components to create in this Container when a child item is specified as a raw configuration object, rather than as an instantiated Component.
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
CSS class to add when the Component is disabled. Defaults to 'x-item-disabled'.
CSS class to add when the Component is disabled. Defaults to 'x-item-disabled'.
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();
Convenience method used for adding items to the bottom right of the panel. Short for Footer Bar.
fbar: [
{ type: 'button', text: 'Button 1' }
]
is equivalent to
dockedItems: [{
xtype: 'toolbar',
dock: 'bottom',
defaults: {minWidth: minButtonWidth},
items: [
{ xtype: 'component', flex: 1 },
{ xtype: 'button', text: 'Button 1' }
]
}]
The minButtonWidth is used as the default minWidth for each of the buttons in the fbar.
Important: This config is only effective for collapsible Panels which are direct child items of a border layout.
true to allow clicking a collapsed Panel's placeholder to display the Panel floated above the layout, false to force the user to fully expand a collapsed region by clicking the expand button to see it again (defaults to true).
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.
Specifies whether the floated component should be automatically focused when it is brought to the front. Defaults to true.
True to apply a frame to the panel panels header (if 'frame' is true).
True to apply a frame to the panel panels header (if 'frame' is true).
Specify as 'top', 'bottom', 'left' or 'right'. Defaults to 'top'.
Specify as 'top', 'bottom', 'left' or 'right'. Defaults to 'top'.
true to hide the expand/collapse toggle button when collapsible == true,
false to display it (defaults to false).
true to hide the expand/collapse toggle button when collapsible == true,
false to display it (defaults to false).
A String which specifies how this Component's encapsulating DOM element will be hidden. Values may be
'display': The Component will be hidden using thedisplay: nonestyle.'visibility': The Component will be hidden using thevisibility: hiddenstyle.'offsets': The Component will be hidden by absolutely positioning it out of the visible area of the document. This is useful when a hidden Component must maintain measurable dimensions. Hiding usingdisplayresults in a Component having zero dimensions.
'display'.
An HTML fragment, or a DomHelper specification to use as the layout element content (defaults to ''). The HTML content is added after the component is rendered, so the document will not contain this HTML at the time the render event is fired. This content is inserted into the body before any configured contentEl is appended.
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.
The class added to each child item of this TabPanel. Defaults to 'x-tabpanel-child'.
The class added to each child item of this TabPanel. Defaults to 'x-tabpanel-child'.
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.
Optional configuration object for the internal card layout. If present, this is passed straight through to the layout's constructor
Convenience method. Short for 'Left Bar' (left-docked, vertical toolbar).
lbar: [
{ xtype: 'button', text: 'Button 1' }
]
is equivalent to
dockedItems: [{
xtype: 'toolbar',
dock: 'left',
items: [
{ xtype: 'button', text: 'Button 1' }
]
}]
(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'); }
}
}
});
A configuration object or an instance of a Ext.ComponentLoader to load remote content for this Component.
A configuration object or an instance of a Ext.ComponentLoader to load remote content for this Component.
Specifies the margin for this component. The margin can be a single numeric value to apply to all sides or it can be a CSS style specification for each style, for example: '10 5 3 10'.
The maximum value in pixels which this Component will set its height to.
Warning: This will override any size management applied by layout managers.
The maximum value in pixels which this Component will set its width to.
Warning: This will override any size management applied by layout managers.
Minimum width of all footer toolbar buttons in pixels (defaults to 75). If set, this will be used as the default value for the Ext.button.Button.minWidth config of each Button added to the footer toolbar via the fbar or buttons configurations. It will be ignored for buttons that have a minWidth configured some other way, e.g. in their own config object or via the defaults of their parent container.
The minimum value in pixels which this Component will set its height to.
Warning: This will override any size management applied by layout managers.
The minimum value in pixels which this Component will set its width to.
Warning: This will override any size management applied by layout managers.
An optional extra CSS class that will be added to this component's Element when the mouse moves over the Element, and removed when the mouse moves out. (defaults to ''). This can be useful for adding customized 'active' or 'hover' styles to the component or any of its children using standard CSS rules.
Specifies the padding for this component. The padding can be a single numeric value to apply to all sides or it can be a CSS style specification for each style, for example: '10 5 3 10'.
Important: This config is only effective for collapsible Panels which are direct child items of a border layout
when not using the 'header' collapseMode.
Optional. A Component (or config object for a Component) to show in place of this Panel when this Panel is collapsed by a border layout. Defaults to a generated Header containing a Tool to re-expand the Panel.
An object or array of objects that will provide custom functionality for this component. The only requirement for a valid plugin is that it contain an init method that accepts a reference of type Ext.Component. When a component is created, if any plugins are available, the component will call the init method on each plugin, passing a reference to itself. Each plugin can then call methods or respond to events on the component as needed to provide its functionality.
Prevent a Header from being created and shown. Defaults to false.
Prevent a Header from being created and shown. Defaults to false.
Convenience method. Short for 'Right Bar' (right-docked, vertical toolbar).
rbar: [
{ xtype: 'button', text: 'Button 1' }
]
is equivalent to
dockedItems: [{
xtype: 'toolbar',
dock: 'right',
items: [
{ xtype: 'button', text: 'Button 1' }
]
}]
True to instruct each Panel added to the TabContainer to not render its header element. This is to ensure that the title of the panel does not appear twice. Defaults to true.
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: '<img src="{imageUrl}" class="x-image-component-img"><div class="x-image-component-desc">{description}>/div<',
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.
Specify the id of the element, a DOM element or an existing Element that this component will be rendered into.
- 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.
Specify as true to apply a Resizer to this Component
after rendering.
May also be specified as a config object to be passed to the constructor of Resizer
to override any defaults. By default the Component passes its minimum and maximum size, and uses
Ext.resizer.Resizer.dynamic: false
A valid Ext.resizer.Resizer handles config string (defaults to 'all'). Only applies when resizable = true.
A valid Ext.resizer.Resizer handles config string (defaults to 'all'). Only applies when resizable = true.
A buffer to be applied if many state events are fired within a short period. Defaults to 100.
A buffer to be applied if many state events are fired within a short period. Defaults to 100.
Specifies whether the floating component should be given a shadow. Set to true to automatically create an Ext.Shadow, or a string indicating the shadow's display Ext.Shadow.mode. Set to false to disable the shadow. (Defaults to 'sides'.)
An array of events that, when fired, should trigger this object to
save its state (defaults to none). stateEvents may be any type
of event supported by this object, including browser or custom events
(e.g., ['click', 'customerchange']).
See stateful for an explanation of saving and
restoring object state.
The unique id for this object to use for state management purposes.
See stateful for an explanation of saving and restoring state.
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.
A custom style specification to be applied to this component's Element. Should be a valid argument to Ext.core.Element.applyStyles.
new Ext.panel.Panel({
title: 'Some Title',
renderTo: Ext.getBody(),
width: 400, height: 300,
layout: 'form',
items: [{
xtype: 'textarea',
style: {
width: '95%',
marginBottom: '10px'
}
},
new Ext.button.Button({
text: 'Send',
minWidth: '100',
style: {
marginBottom: '10px'
}
})
]
});
The class that is added to the content target when you set styleHtmlContent to true. Defaults to 'x-html'
The class that is added to the content target when you set styleHtmlContent to true. Defaults to 'x-html'
True to automatically style the html inside the content target of this component (body for panels). Defaults to false.
True to automatically style the html inside the content target of this component (body for panels). Defaults to false.
If true, suspend calls to doLayout. Useful when batching multiple adds to a container and not passing them as multiple arguments or an array.
Optional configuration object for the internal Ext.tab.Bar. If present, this is passed straight through to the TabBar's constructor
The position where the tab strip should be rendered (defaults to 'top').
In 4.0, The only other supported value is 'bottom'.
Convenience method. Short for 'Top Bar'.
tbar: [
{ xtype: 'button', text: 'Button 1' }
]
is equivalent to
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
items: [
{ xtype: 'button', text: 'Button 1' }
]
}]
true to allow expanding and collapsing the panel (when collapsible = true)
by clicking anywhere in the header bar, false) to allow it only by clicking to tool button
(defaults to false)).
An array of Ext.panel.Tool configs/instances to be added to the header tool area. The tools are stored as child components of the header container. They can be accessed using down and {#query}, as well as the other component methods. The toggle tool is automatically created if collapsible is set to true.
Note that, apart from the toggle tool which is provided when a panel is collapsible, these tools only provide the visual button. Any required functionality must be provided by adding handlers that implement the necessary behavior.
Example usage:
tools:[{
type:'refresh',
qtip: 'Refresh form Data',
// hidden:true,
handler: function(event, toolEl, panel){
// refresh logic
}
},
{
type:'help',
qtip: 'Get Help',
handler: function(event, toolEl, panel){
// show help here
}
}]
An data and
tplWriteMode configurations.
The Ext.(X)Template method to use when
updating the content area of the Component. Defaults to 'overwrite'
(see Ext.XTemplate.overwrite).
Properties
If this Panel is configured draggable, this property will contain an instance of Ext.dd.DragSource which handles dragging the Panel.
The developer must provide implementations of the abstract methods of Ext.dd.DragSource in order to supply behaviour for each stage of the drag/drop process. See draggable.
Read-only property indicating whether or not the component can be dragged
Read-only property indicating whether or not the component can be dragged
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.
For example, the dropdown BoundList of a ComboBox which is in a Window will have the Window as its
floatParent
See floating and zIndexManager
Read-only property indicating the width of any framing elements which were added within the encapsulating element to provide graphical, rounded borders. See the frame config.
This is an object containing the frame width in pixels for all four sides of the Component containing the following properties:
topThe width of the top framing element in pixels.rightThe width of the right framing element in pixels.bottomThe width of the bottom framing element in pixels.leftThe width of the left framing element in pixels.
@deprecated 4.0 Replaced by getActiveAnimation Returns thq current animation if this object has any effects actively running or queued, else returns false.
At this point the item hasn't been removed from the items collection. As such, if we want to check if there are no more tabs left, we have to check for one, as opposed to 0.
The MixedCollection containing all the child items of this container.
The MixedCollection containing all the child items of this container.
This is an internal flag that you use when creating custom components. By default this is set to true which means that every component gets a mask when its disabled. Components like FieldContainer, FieldSet, Field, Button, Tab override this property to false since they want to implement custom disable logic.
Read-only property indicating whether or not the component has been rendered.
Read-only property indicating whether or not the component has been rendered.
Stops any running effects and clears this object's internal effects queue if it contains any additional effects that haven't started yet.
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.
See floating and floatParent
Methods
Adds Component(s) to this Container.
Description:
- Fires the beforeadd event before adding.
- The Container's default config values will be applied
accordingly (see
defaultsfor details). - Fires the
addevent after the component has been added.
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.

Returns
- 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 (
thisreference) 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 : ObjectThe scope (
thisreference) in which the handler function is executed. If omitted, defaults to the object which fired the event. - delay : NumberThe number of milliseconds to delay the invocation of the handler after the event fires.
- single : BooleanTrue to add a handler to handle just the next firing of the event, and then remove itself.
- buffer : NumberCauses 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 : ObservableOnly call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.
- element : StringThis 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

this
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
fromAn 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.toAn object which specifies end values for the properties being animated.durationThe duration in milliseconds for which the animation will run.easingA 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
keyframesThis 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.listenersThis is a standard listeners configuration object which may be used to inject behaviour at either thebeforeanimateevent or theafteranimateevent.Animating an Element
When animating an Element, the following properties may be specified infrom,to, andkeyframeobjects:xThe page X position in pixels.yThe page Y position in pixelsleftThe element's CSSleftvalue. Units must be supplied.topThe element's CSStopvalue. Units must be supplied.widthThe element's CSSwidthvalue. Units must be supplied.heightThe element's CSSheightvalue. Units must be supplied.scrollLeftThe element'sscrollLeftvalue.scrollTopThe element'sscrollLeftvalue.opacityThe element'sopacityvalue. This must be a value between0and1.
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 infrom,to, andkeyframeobjects:xThe Component's page X position in pixels.yThe Component's page Y position in pixelsleftThe Component'sleftvalue in pixels.topThe Component'stopvalue in pixels.widthThe Component'swidthvalue in pixels.widthThe Component'swidthvalue in pixels.dynamicSpecify 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 withdynamic: trueand 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

Parameters
- silent : Boolean
Passing false will supress the 'enable' event from being fired.
Returns
- void
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
- events : String/Array
The event name to bubble, or an Array of event names.
Returns
- void
Expands the panel body so that it becomes visible. Fires the beforeexpand event which will cancel the expand action if it returns false.
Parameters
