Base class for any Ext.BoxComponent that may contain other Components. Containers handle the
basic behavior of containing items, namely adding, inserting and removing items.
The most commonly used Container classes are Ext.Panel, Ext.Window and Ext.TabPanel.
If you do not need the capabilities offered by the aforementioned classes you can create a lightweight
Container to be encapsulated by an HTML element to your specifications by using the
autoEl
config option. This is a useful technique when creating
embedded column layouts inside FormPanels
for example.
The code below illustrates both how to explicitly create a Container, and how to implicitly
create one using the 'container'
xtype:
// explicitly create a Container
var embeddedColumns = new Ext.Container({
autoEl: 'div', // This is the default
layout: 'column',
defaults: {
// implicitly create Container by specifying xtype
xtype: 'container',
autoEl: 'div', // This is the default.
layout: 'form',
columnWidth: 0.5,
style: {
padding: '10px'
}
},
// The two items below will be Ext.Containers, each encapsulated by a <DIV> element.
items: [{
items: {
xtype: 'datefield',
name: 'startDate',
fieldLabel: 'Start date'
}
}, {
items: {
xtype: 'datefield',
name: 'endDate',
fieldLabel: 'End date'
}
}]
});
Layout
Container classes delegate the rendering of child Components to a layout
manager class which must be configured into the Container using the
layout
configuration property.
When either specifying child items
of a Container,
or dynamically adding Components to a Container, remember to
consider how you wish the Container to arrange those child elements, and
whether those child elements need to be sized using one of Ext's built-in
layout
schemes. By default, Containers use the
ContainerLayout scheme which only
renders child components, appending them one after the other inside the
Container, and does not apply any sizing at all.
A common mistake is when a developer neglects to specify a
layout
(e.g. widgets like GridPanels or
TreePanels are added to Containers for which no layout
has been specified). If a Container is left to use the default
ContainerLayout scheme, none of its
child components will be resized, or changed in any way when the Container
is resized.
Certain layout managers allow dynamic addition of child components.
Those that do include Ext.layout.CardLayout,
Ext.layout.AnchorLayout, Ext.layout.FormLayout, and
Ext.layout.TableLayout. For example:
// Create the GridPanel.
var myNewGrid = new Ext.grid.GridPanel({
store: myStore,
columns: myColumnModel,
title: 'Results', // the title becomes the title of the tab
});
myTabPanel.add(myNewGrid); // Ext.TabPanel implicitly uses CardLayout
myTabPanel.setActiveTab(myNewGrid);
The example above adds a newly created GridPanel to a TabPanel. Note that
a TabPanel uses Ext.layout.CardLayout as its layout manager which
means all its child items are sized to fit
exactly into its client area.
Overnesting is a common problem.
An example of overnesting occurs when a GridPanel is added to a TabPanel
by wrapping the GridPanel inside a wrapping Panel (that has no
layout
specified) and then add that wrapping Panel
to the TabPanel. The point to realize is that a GridPanel is a
Component which can be added directly to a Container. If the wrapping Panel
has no layout
configuration, then the overnested
GridPanel will not be sized as expected.
Adding via remote configuration
A server side script can be used to add Components which are generated dynamically on the server.
An example of adding a GridPanel to a TabPanel where the GridPanel is generated by the server
based on certain parameters:
// execute an Ajax request to invoke server side script:
Ext.Ajax.request({
url: 'gen-invoice-grid.php',
// send additional parameters to instruct server script
params: {
startDate: Ext.getCmp('start-date').getValue(),
endDate: Ext.getCmp('end-date').getValue()
},
// process the response object to add it to the TabPanel:
success: function(xhr) {
var newComponent = eval(xhr.responseText); // see discussion below
myTabPanel.add(newComponent); // add the component to the TabPanel
myTabPanel.setActiveTab(newComponent);
},
failure: function() {
Ext.Msg.alert("Grid create failed", "Server communication failure");
}
});
The server script needs to return an executable Javascript statement which, when processed
using eval()
, will return either a config object with an xtype,
or an instantiated Component. The server might return this for example:
(function() {
function formatDate(value){
return value ? value.dateFormat('M d, Y') : '';
};
var store = new Ext.data.Store({
url: 'get-invoice-data.php',
baseParams: {
startDate: '01/01/2008',
endDate: '01/31/2008'
},
reader: new Ext.data.JsonReader({
record: 'transaction',
idProperty: 'id',
totalRecords: 'total'
}, [
'customer',
'invNo',
{name: 'date', type: 'date', dateFormat: 'm/d/Y'},
{name: 'value', type: 'float'}
])
});
var grid = new Ext.grid.GridPanel({
title: 'Invoice Report',
bbar: new Ext.PagingToolbar(store),
store: store,
columns: [
{header: "Customer", width: 250, dataIndex: 'customer', sortable: true},
{header: "Invoice Number", width: 120, dataIndex: 'invNo', sortable: true},
{header: "Invoice Date", width: 100, dataIndex: 'date', renderer: formatDate, sortable: true},
{header: "Value", width: 120, dataIndex: 'value', renderer: 'usMoney', sortable: true}
],
});
store.load();
return grid; // return instantiated component
})();
When the above code fragment is passed through the eval
function in the success handler
of the Ajax request, the code is executed by the Javascript processor, and the anonymous function
runs, and returns the instantiated grid component.
Note: since the code above is generated by a server script, the baseParams
for
the Store, the metadata to allow generation of the Record layout, and the ColumnModel
can all be generated into the code since these are all known on the server.

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.CardLayout and
Ext.layout.FitLayout). Related to
Ext.layout.ContainerLayout.activeItem.

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',

The sizing and positioning of a Component's internal Elements is the responsibility of
the Component's layout manager which sizes a Component's internal structure in response to the Component being sized.
Generally, developers will not use this configuration as all provided Components which need their internal
elements sizing (Such as input fields) come with their own componentLayout managers.
The default layout manager will be used on instances of the base Ext.Component class
which simply sizes the Component's encapsulating element to the height and width specified in the setSize method.

Optional. Specify an existing HTML element, or the id
of an existing HTML element to use as the content
for this component.
- Description :
This config option is used to take an existing HTML element and place it in the layout element
of a new component (it simply moves the specified DOM element after the Component is rendered to use as the content.
- Notes :
The specified HTML element is appended to the layout element of the component
after any configured
HTML has been inserted, and so the document will not contain this element at the time the
render event is fired.
The specified HTML element used will not participate in any
layout
scheme that the Component may use. It is just HTML. Layouts operate on child
items
.

or the x-hide-display
CSS class to

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 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({ // 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.
})
]

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
.

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.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.ComponentMgr which requires a unique
id
.
var c = new Ext.Panel({ //

** IMPORTANT: be sure to specify a layout
if needed ! **
A single item, or an array of child Components to be added to this container,
for example:
// specifying a single item
items: {...},
layout: 'fit', // specify a layout!
// specifying multiple items
items: [{...}, {...}],
layout: 'hbox', // specify a layout!
Each item may be:
- any type of object based on Ext.Component
- a fully instanciated object or
- an object literal that:
- has a specified
xtype
- the Ext.Component.xtype specified is associated with the Component
desired and should be chosen from one of the available xtypes as listed
in Ext.Component.
- If an
xtype
is not explicitly
specified, the defaultType for that Container is used.
- will be "lazily instanciated", avoiding the overhead of constructing a fully
instanciated Component object
Notes:
- Ext uses lazy rendering. Child Components will only be rendered
should it become necessary. Items are automatically laid out when they are first
shown (no sizing is done while hidden), or in response to a doLayout call.
- Do not specify
contentEl

*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

as a String:
- Specify as an Object
layout: {

}

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

each layout type, see the layout class corresponding to the type
specified.

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

An object 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.

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.

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: '
"{imageUrl}" class="x-image-component-img">"x-image-component-desc">{description}
',
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.

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

Adds the specified events to the list of events which this Observable may fire.
Parameters
Returns
addListener(
String eventName, Function handler, [Object scope], [Object options] ) : Void
Appends an event handler to this object.
Appends an event handler to this object.
Parameters
- eventName : String
The name of the event to listen for. May also be an object who's property names are event names. See
- handler : Function
The method the event invokes.
- scope : Object
(optional) The scope (this
reference) in which the handler function is executed.
If omitted, defaults to the object which fired the event.
- options : Object
(optional) An object containing handler configuration.
properties. This may contain any of the following properties:
- scope : Object
The scope (this
reference) in which the handler function is executed.
If omitted, defaults to the object which fired the event.
- delay : Number
The number of milliseconds to delay the invocation of the handler after the event fires.
- single : Boolean
True to add a handler to handle just the next firing of the event, and then remove itself.
- buffer : Number
Causes the handler to be scheduled to run in an
Ext.util.DelayedTask delayed
by the specified number of milliseconds. If the event fires again within that time, the original
handler is
not invoked, but the new handler is scheduled in its place.
- target : Observable
Only call the handler if the event was fired on the target Observable, not
if the event was bubbled up from a child Observable.
- element : String
This option is only valid for listeners bound to Components.
The name of a Component property which references an element to add a listener to.
This option is useful during Component construction to add DOM event listeners to elements of Components which
will exist only after the Component is rendered. For example, to add a click listener to a Panel's body:
new Ext.Panel({
title: 'The title',
listeners: {
click: this.handlePanelClick,
element: 'body'
}
});
When added in this way, the options available are the options applicable to Ext.core.Element.addListener
Combining Options
Using the options argument, it is possible to combine different types of listeners:
A delayed, one-time listener.
myPanel.on('hide', this.handleClick, this, {
single: true,
delay: 100
});
Attaching multiple handlers in 1 call
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple events. For example:
myGridPanel.on({
cellClick: this.onCellClick,
mouseover: this.onMouseOver,
mouseout: this.onMouseOut,
scope: this // Important. Ensure "this" is correct during handler execution
});
.
Returns

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

Parameters
Returns
Enables events fired by this Observable to bubble up an owner hierarchy by calling
this.getBubbleTarget() if present....
Enables events fired by this Observable to bubble up an owner hierarchy by calling
this.getBubbleTarget()
if present. There is no implementation in the Observable base class.
This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default
implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to
access the required target more quickly.
Example:
Ext.override(Ext.form.Field, {
// Add functionality to Field's initComponent to enable the change event to bubble
initComponent : Ext.Function.createSequence(Ext.form.Field.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');
}
}
});
