13  * @class Roo.View
14  * @extends Roo.util.Observable
15  * Create a &quot;View&quot; for an element based on a data model or UpdateManager and the supplied DomHelper template. 
16  * This class also supports single and multi selection modes. &lt;br&gt;
17  * Create a data model bound view:
18  &lt;pre&gt;&lt;code&gt;
19  var store = new Roo.data.Store(...);
20
21  var view = new Roo.View({
22     el : &quot;my-element&quot;,
23     tpl : '&amp;lt;div id=&quot;{0}&quot;&amp;gt;{2} - {1}&amp;lt;/div&amp;gt;', // auto create template
24  
25     singleSelect: true,
26     selectedClass: &quot;ydataview-selected&quot;,
27     store: store
28  });
29
30  // listen for node click?
31  view.on(&quot;click&quot;, function(vw, index, node, e){
32  alert('Node &quot;' + node.id + '&quot; at index: ' + index + &quot; was clicked.&quot;);
33  });
34
35  // load XML data
36  dataModel.load(&quot;foobar.xml&quot;);
37  &lt;/code&gt;&lt;/pre&gt;
38  For an example of creating a JSON/UpdateManager view, see {@link Roo.JsonView}.
39  * &lt;br&gt;&lt;br&gt;
40  * &lt;b&gt;Note: The root of your template must be a single node. Table/row implementations may work but are not supported due to
41  * IE&quot;s limited insertion support with tables and Opera&quot;s faulty event bubbling.&lt;/b&gt;
42  * 
43  * Note: old style constructor is still suported (container, template, config)
44  * 
45  * @constructor
46  * Create a new View
47  * @param {Object} config The config object
