Available since: 3.4.0
Config options
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).
Available since: Ext 2
Sets the alignment of the header and rendered columns. Defaults to 'left'.
Defaults to: 'left'
Available since: 3.4.0
The alt text to use for the image element.
Defaults to: ''
Available since: 3.4.0
If true the container will automatically destroy any contained component that is removed from it, else destruction must be handled manually.
Defaults to: true
Available since: Ext 2
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'
}
}
Available since: Ext 2
This config is intended mainly for non-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. If floating is true, the value of this config is omited as if it is true
.
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.
Defaults to: false
Available since: 4.0.0
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
Available since: 4.0.0
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
Available since: Ext 2
The base CSS class to apply to this components's element. This will also be prepended to elements within this component like Panel's body will get a class x-panel-body. This means that if you create a subclass of Panel, and you want it to get all the Panels styling for the element and the body, you leave the baseCls x-panel and use componentCls to add specific styling for this component.
Defaults to: Ext.baseCSSPrefix + 'column-header ' + Ext.baseCSSPrefix + 'unselectable'
Available since: 4.0.0
Overrides: Ext.grid.header.Container.baseCls
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'.
Defaults to: true
Available since: 4.0.0
Overrides: Ext.AbstractComponent.border
An array of events that, when fired, should be bubbled to any parent container. See Ext.util.Observable.enableBubble.
Defaults to: ['add', 'remove']
Available since: Ext 3
An array describing the child elements of the Component. Each member of the array is an object with these properties:
name
- The property name on the Component for the child element.itemId
- The id to combine with the Component's id that is the id of the child element.id
- The id of the child element.
If the array member is a string, it is equivalent to { name: m, itemId: m }
.
For example, a Component which renders a title and body text:
Ext.create('Ext.Component', {
renderTo: Ext.getBody(),
renderTpl: [
'<h1 id="{id}-title">{title}</h1>',
'<p>{msg}</p>',
],
renderData: {
title: "Error",
msg: "Something went wrong"
},
childEls: ["title"],
listeners: {
afterrender: function(cmp){
// After rendering the component will have a title property
cmp.title.setStyle({color: "red"});
}
}
});
A more flexible, but somewhat slower, approach is renderSelectors.
Available since: 4.0.5
An optional extra CSS class that will be added to this component's Element. This can be useful for adding customized styles to the component or any of its children using standard CSS rules.
Defaults to: ''
Available since: Ext 1
An optional array of sub-column definitions. This column becomes a group, and houses the columns defined in the
columns
config.
Group columns may not be sortable. But they may be hideable and moveable. And you may move headers into and out of a group. Note that if all sub columns are dragged out of a group, the group is destroyed.
Available since: 4.0.0
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.
Available since: 4.0.0
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.
Available since: 4.0.0
Specify an existing HTML element, or the id
of an existing HTML element to use as the content for this component.
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.
Available since: Ext 3
The name of the field in the grid's Ext.data.Store's Ext.data.Model definition from which to draw the column's value. Required.
Available since: 3.4.0
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: 'gridcolumn'
Available since: Ext 2
Overrides: Ext.container.AbstractContainer.defaultType
Width of the header if no width or flex is specified. Defaults to 100.
Defaults to: 100
Available since: 4.0.0
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.
Defaults are applied to both config objects and instantiated components conditionally so as not to override existing properties in the item (see Ext.applyIf).
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: [
// default will not be applied here, panel1 will be autoScroll: false
{
xtype: 'panel',
id: 'panel1',
autoScroll: false
},
// this component will have autoScroll: true
new Ext.panel.Panel({
id: 'panel2'
})
]
Available since: Ext 2
True to disable the component.
Defaults to: false
Available since: Ext 2
CSS class to add when the Component is disabled. Defaults to 'x-item-disabled'.
Defaults to: 'x-item-disabled'
Available since: 4.0.0
False to disable drag-drop reordering of this column. Defaults to true.
Defaults to: true
Available since: 4.0.0
Overrides: Ext.Component.draggable
Available since: 3.4.0
This cfg has been deprecated since .
True to prevent the column from being resizable.
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.
Defaults to: false
Available since: 4.0.0
Overrides: Ext.AbstractComponent.floating, Ext.Component.floating
Specifies whether the floated component should be automatically focused when it is brought to the front.
Defaults to: true
Available since: 4.0.0
Specify as true
to have the Component inject framing elements within the Component at render time to provide a
graphical rounded frame around the Component content.
This is only necessary when running on outdated, or non standard-compliant browsers such as Microsoft's Internet Explorer prior to version 9 which do not support rounded corners natively.
The extra space taken up by this framing is available from the read only property frameSize.
Available since: 4.0.0
A function which returns the CSS class to apply to the icon image.
Available since: 3.4.0
Parameters
- v : Object
The value of the column's configured field (if any).
- metadata : Object
- r : Ext.data.Model
The Record providing the data.
- rowIndex : Number
The row index..
- colIndex : Number
The column index.
- store : Ext.data.Store
The Store which is providing the data Model.
If the grid uses a Ext.grid.feature.Grouping, this option may be used to disable the header menu item to group by the column selected. By default, the header menu group option is enabled. Set to false to disable (but still show) the group option in the header menu for the column.
Available since: 3.4.0
A function called when the icon is clicked.
Available since: 3.4.0
Parameters
- view : Ext.view.Table
The owning TableView.
- rowIndex : Number
The row index clicked on.
- colIndex : Number
The column index clicked on.
- item : Object
The clicked item (or this Column if multiple items were not configured).
- e : Event
The click event.
The height of this component in pixels.
The height of this component in pixels.
Available since: 4.0.0
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: none
style.'visibility'
: The Component will be hidden using thevisibility: hidden
style.'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 usingdisplay
results in a Component having zero dimensions.
Defaults to: 'display'
Available since: Ext 1
False to prevent the user from hiding this column. Defaults to true.
Defaults to: true
Available since: 3.4.0
An HTML fragment, or a DomHelper specification to use as the layout element content. 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.
Defaults to: ''
Available since: Ext 3
The URL of an image to display as the clickable element in the column. Defaults to
Ext.BLANK_IMAGE_URL
.
Available since: 3.4.0
A CSS class to apply to the icon image. To determine the class dynamically, configure the Column with
a getClass
function.
Available since: 3.4.0
The unique id of this component instance.
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
.
Defaults to an auto-assigned id.
Available since: Ext 1
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, Ext.container.Container.query
, Ext.container.Container.down
and
Ext.container.Container.child
.
Note: to access the container of an item see ownerCt.
Available since: Ext 3

getClass
function. - getClass : Function
A function which returns the CSS class to apply to the icon image.
Parameters
- v : Object
The value of the column's configured field (if any).

The Store which is providing the data Model.
- v : Object
- handler : Function
A function called when the icon is clicked.

The scope (
this
reference) in which thehandler
andgetClass
functions are executed. Fallback defaults are this Column's configured scope, then this Column. - tooltip : String
A tooltip message to be displayed on hover.
- disabled : Boolean
If true, the action will not respond to click events, and will be displayed semi-opaque. Ext.tip.QuickTipManager must have been initialized.
Overrides: Ext.container.AbstractContainer.items
Important: In order for child items to be correctly sized and
positioned, typically a layout manager must be specified through
the layout
configuration option.
The sizing and positioning of child items is the responsibility of the Container's layout manager which creates and manages the type of layout you have in mind. For example:
If the layout configuration is not explicitly specified for a general purpose container (e.g. Container or Panel) the default layout manager will be used which does nothing but render child components sequentially into the Container (no sizing or positioning will be performed in this situation).
layout
may be specified as either as an Object or as a String:
- Specify as an Object
- Example usage:
type
- Layout specific configuration properties
- Specify as a String
- Example usage:
layout
layout: {
type: 'vbox',
align: 'left'
}
The layout type to be used for this container. If not specified, a default Ext.layout.container.Auto will be created and used.
Valid layout type
values are:
Additional layout specific configuration properties may also be
specified. For complete details regarding the valid config options for
each layout type, see the layout class corresponding to the type
specified.
layout: 'vbox'
The layout type
to be used for this container (see list
of valid layout type values above).
Additional layout specific configuration properties. For complete
details regarding the valid config options for each layout type, see the
layout class corresponding to the layout
specified.
Available since: Ext 2
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 Components
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'); }
}
}
});
Available since: 1.1.0

Available since: 4.0.0
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. This can be useful for adding customized 'active' or 'hover' styles to the component or any of its children using standard CSS rules.
Defaults to: ''
Available since: Ext 2
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'.
Available since: 4.0.0
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.
Available since: Ext 2
The data used by renderTpl in addition to the following property values of the component:
- id
- ui
- uiCls
- baseCls
- componentCls
- frame
See renderSelectors and childEls for usage examples.
Available since: Ext JS 4.0.7
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 renderes a title and description into its element:
Ext.create('Ext.Component', {
renderTo: Ext.getBody(),
renderTpl: [
'<h1 class="title">{title}</h1>',
'<p>{desc}</p>'
],
renderData: {
title: "Error",
desc: "Something went wrong"
},
renderSelectors: {
titleEl: 'h1.title',
descEl: 'p'
},
listeners: {
afterrender: function(cmp){
// After rendering the component will have a titleEl and descEl properties
cmp.titleEl.setStyle({color: "red"});
}
}
});
For a faster, but less flexible, alternative that achieves the same end result (properties for child elements on the Component after render), see childEls and addChildEls.
Available since: 4.0.0
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.
Available since: Ext 2
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 and childEls options.
Defaults to: '<div id="{id}-titleContainer" class="' + Ext.baseCSSPrefix + 'column-header-inner">' + '<span id="{id}-textEl" class="' + Ext.baseCSSPrefix + 'column-header-text">' + '{text}' + '</span>' + '<tpl if="!values.menuDisabled">' + '<div id="{id}-triggerEl" class="' + Ext.baseCSSPrefix + 'column-header-trigger"></div>' + '</tpl>' + '</div>'
Available since: 4.0.0
Overrides: Ext.AbstractComponent.renderTpl
A renderer is an 'interceptor' method which can be used transform data (value, appearance, etc.) before it is rendered. Example:
{
renderer: function(value){
if (value === 1) {
return '1 person';
}
return value + ' people';
}
}
Defaults to: false
Available since: 3.4.0
Parameters
- value : Object
The data value for the current cell
- metaData : Object
A collection of metadata about the current cell; can be used or modified by the renderer. Recognized properties are: tdCls, tdAttr, and style.
- record : Ext.data.Model
The record for the current row
- rowIndex : Number
The index of the current row
- colIndex : Number
The index of the current column
- store : Ext.data.Store
The data store
- view : Ext.view.View
The current view
Returns
- String
The HTML string to be rendered.
Set to false
to prevent the column from being resizable. Defaults to true
Available since: 3.4.0
Overrides: Ext.Component.resizable, Ext.grid.column.Column.resizable
A valid Ext.resizer.Resizer handles config string. Only applies when resizable = true.
Defaults to: 'all'
Available since: 4.0.0
A buffer to be applied if many state events are fired within a short period.
Defaults to: 100
Available since: 4.0.6
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'
Available since: 4.0.0
False to disable sorting of this column. Whether local/remote sorting is used is specified in
Ext.data.Store.remoteSort
. Defaults to true.
Defaults to: false
Available since: 3.4.0
Overrides: Ext.grid.header.Container.sortable, Ext.grid.column.Column.sortable
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.
Available since: 4.0.0
The unique id for this object to use for state management purposes.
See stateful for an explanation of saving and restoring state.
Available since: 4.0.0
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.
Defaults to: true
Available since: 4.0.0
Prevent grid row selection upon mousedown.
Defaults to: true
Available since: 3.4.0

The class that is added to the content target when you set styleHtmlContent to true.
Defaults to: 'x-html'
Available since: 4.0.0
True to automatically style the html inside the content target of this component (body for panels).

The xtype
configuration option can be used to optimize Component creation and rendering. It serves as a
shortcut to the full componet name. For example, the component Ext.button.Button
has an xtype of button
.
You can define your own xtype on a custom component by specifying the
alias config option with a prefix of widget
. For example:
Ext.define('PressMeButton', {
extend: 'Ext.button.Button',
alias: 'widget.pressmebutton',
text: 'Press Me'
})
Any Component can be created implicitly as an object config with an xtype specified, allowing it to be declared and passed into the rendering pipeline without actually being instantiated as an object. Not only is rendering deferred, but the actual creation of the object itself is also deferred, saving memory and resources until they are actually needed. In complex, nested layouts containing many Components, this can make a noticeable improvement in performance.
// Explicit creation of contained Components:
var panel = new Ext.Panel({
...
items: [
Ext.create('Ext.button.Button', {
text: 'OK'
})
]
};
// Implicit creation using xtype:
var panel = new Ext.Panel({
...
items: [{
xtype: 'button',
text: 'OK'
}]
};
In the first example, the button will always be created immediately during the panel's initialization. With many added Components, this approach could potentially slow the rendering of the page. In the second example, the button will not be created or rendered until the panel is actually displayed in the browser. If the panel is never displayed (for example, if it is a tab that remains hidden) then the button will never be created and will never consume any resources whatsoever.

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

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.

Available since: 3.4.0
Parameters
- config : Object
Returns
Fires
Overrides: Ext.util.Floating.constructor, Ext.Component.constructor
Adds Component(s) to this Container. ...Adds Component(s) to this Container.
Description:
- Fires the beforeadd event before adding.
- The Container's default config values will be applied
accordingly (see
defaults
for details).
- Fires the
add
event 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')

Perform custom animation on this object. ...Perform custom animation on this object.
This method is applicable to both 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.

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: [{

initComponent( )privateThe initComponent template method is an important initialization step for a Component. ...The initComponent template method is an important initialization step for a Component. It is intended to be
implemented by each subclass of Ext.Component to provide any needed constructor logic. The
initComponent method of the class being created is called first, with each initComponent method
up the hierarchy to Ext.Component being called thereafter. This makes it easy to implement and,
if needed, override the constructor logic of the Component at any step in the hierarchy.
The initComponent method must contain a call to callParent in order
to ensure that the parent class' initComponent method is also called.
The following example demonstrates using a dynamic string for the text of a button at the time of
instantiation of the class.
Ext.define('DynamicButtonText', {
extend: 'Ext.button.Button',
initComponent: function() {
this.text = new Date();
this.renderTo = Ext.getBody();
this.callParent();

Parameters
- index : Number
The index at which the Component will be inserted
into the Container's items collection
- component : Ext.Component
The child Component to insert.
Ext uses lazy rendering, and will only render the inserted Component should
it become necessary.
A Component config object may be passed in order to avoid the overhead of
constructing a real Component object if lazy rendering might mean that the
inserted Component will not be rendered immediately. To take advantage of
this 'lazy instantiation', set the Ext.Component.xtype config
property to the registered type of the Component wanted.
For a list of all available xtypes, see Ext.Component.

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'
}
});
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
});
One can also specify options for each event handler separately:
myGridPanel.on({
cellClick: {fn: this.onCellClick, scope: this, single: true},
mouseover: {fn: panel.onMouseOver, scope: panel}
});

Adds Component(s) to this Container.
Description:
- Fires the beforeadd event before adding.
- The Container's default config values will be applied
accordingly (see
defaults
for details). - Fires the
add
event 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')

Perform custom animation on this object.
This method is applicable to both 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 thebeforeanimate
event or theafteranimate
event.
Animating an Element
When animating an Element, the following properties may be specified infrom
, to
, and keyframe
objects:x
The page X position in pixels.y
The page Y position in pixelsleft
The element's CSSleft
value. Units must be supplied.top
The element's CSStop
value. Units must be supplied.width
The element's CSSwidth
value. Units must be supplied.height
The element's CSSheight
value. Units must be supplied.scrollLeft
The element'sscrollLeft
value.scrollTop
The element'sscrollLeft
value.opacity
The element'sopacity
value. This must be a value between0
and1
.
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
, and keyframe
objects:x
The Component's page X position in pixels.y
The Component's page Y position in pixelsleft
The Component'sleft
value in pixels.top
The Component'stop
value in pixels.width
The Component'swidth
value in pixels.width
The Component'swidth
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.

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');
}
}
});

The initComponent template method is an important initialization step for a Component. It is intended to be implemented by each subclass of Ext.Component to provide any needed constructor logic. The initComponent method of the class being created is called first, with each initComponent method up the hierarchy to Ext.Component being called thereafter. This makes it easy to implement and, if needed, override the constructor logic of the Component at any step in the hierarchy.
The initComponent method must contain a call to callParent in order to ensure that the parent class' initComponent method is also called.
The following example demonstrates using a dynamic string for the text of a button at the time of instantiation of the class.
Ext.define('DynamicButtonText', {
extend: 'Ext.button.Button',
initComponent: function() {
this.text = new Date();
this.renderTo = Ext.getBody();
this.callParent();
}
});
Ext.onReady(function() {
Ext.create('DynamicButtonText');
});
Available since: 4.0.0
Fires
Overrides: Ext.grid.header.Container.initComponent

return this;
}
});
var awesome = new My.awesome.Class({

Parameters
- index : Number
The index at which the Component will be inserted into the Container's items collection
- component : Ext.Component
The child Component to insert.
Ext uses lazy rendering, and will only render the inserted Component should it become necessary.
A Component config object may be passed in order to avoid the overhead of constructing a real Component object if lazy rendering might mean that the inserted Component will not be rendered immediately. To take advantage of this 'lazy instantiation', set the Ext.Component.xtype config property to the registered type of the Component wanted.
For a list of all available xtypes, see Ext.Component.

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.
Returns the next node in the Component tree in tree traversal order.
Note that this is not limited to siblings, and if invoked upon a node with no matching siblings, will walk the tree to attempt to find a match. Contrast with nextSibling.
Available since: 4.0.0
Parameters
- selector : String (optional)
A ComponentQuery selector to filter the following nodes.
Returns
- Ext.Component
The next node (or the next node which matches the selector). Returns null if there is no matching node.
Fires
Returns the next sibling of this Component.
Optionally selects the next sibling which matches the passed ComponentQuery selector.
May also be refered to as next()
Note that this is limited to siblings, and if no siblings of the item match, null
is returned. Contrast with
nextNode
Available since: 4.0.0
Parameters
- selector : String (optional)
A ComponentQuery selector to filter the following items.
Returns
- Ext.Component
The next sibling (or the next sibling which matches the selector). Returns null if there is no matching sibling.
Shorthand for addListener.
Available since: 1.1.0
Parameters
- eventName : String
The name of the event to listen for. May also be an object who's property names are event names.
- fn : Function
The method the event invokes. Will be called with arguments given to fireEvent plus the
options
parameter described below. - scope : Object (optional)
The scope (
this
reference) in which the handler function is executed. If omitted, defaults to the object which fired the event. - options : Object (optional)
An object containing handler configuration.
Note: Unlike in ExtJS 3.x, 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.
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' } });
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 });
One can also specify options for each event handler separately:
myGridPanel.on({ cellClick: {fn: this.onCellClick, scope: this, single: true}, mouseover: {fn: panel.onMouseOver, scope: panel} });
