|
|
* @class Ext.DataView
|
|
* @extends Ext.BoxComponent
|
|
* A mechanism for displaying data using custom layout templates and formatting. DataView uses an {@link Ext.XTemplate}
|
|
* as its internal templating mechanism, and is bound to an {@link Ext.data.Store}
|
|
* so that as the data in the store changes the view is automatically updated to reflect the changes. The view also
|
|
* provides built-in behavior for many common events that can occur for its contained items including click, doubleclick,
|
|
* mouseover, mouseout, etc. as well as a built-in selection model. <b>In order to use these features, an {@link #itemSelector}
|
|
* config must be provided for the DataView to determine what nodes it will be working with.</b>
|
|
*
|
|
* <p>The example below binds a DataView to a {@link Ext.data.Store} and renders it into an {@link Ext.Panel}.</p>
