-/**
- * @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>
- * <pre><code>
-var store = new Ext.data.JsonStore({
- url: 'get-images.php',
- root: 'images',
- fields: [
- 'name', 'url',
- {name:'size', type: 'float'},
- {name:'lastmod', type:'date', dateFormat:'timestamp'}
- ]
-});
-store.load();
-
-var tpl = new Ext.XTemplate(
- '<tpl for=".">',
- '<div class="thumb-wrap" id="{name}">',
- '<div class="thumb"><img src="{url}" title="{name}"></div>',
- '<span class="x-editable">{shortName}</span></div>',
- '</tpl>',
- '<div class="x-clear"></div>'
-);
