* @extends Ext.Panel
* <p>The TreePanel provides tree-structured UI representation of tree-structured data.</p>
* <p>{@link Ext.tree.TreeNode TreeNode}s added to the TreePanel may each contain metadata
* used by your application in their {@link Ext.tree.TreeNode#attributes attributes} property.</p>
* <p><b>A TreePanel must have a {@link #root} node before it is rendered.</b> This may either be
* specified using the {@link #root} config option, or using the {@link #setRootNode} method.
* <p>An example of tree rendered to an existing div:</p><pre><code>
var tree = new Ext.tree.TreePanel({
renderTo: 'tree-div',
useArrows: true,
autoScroll: true,
animate: true,
enableDD: true,
containerScroll: true,
border: false,
// auto create TreeLoader
dataUrl: 'get-nodes.php',
root: {
nodeType: 'async',
text: 'Ext JS',
draggable: false,
id: 'source'
}
});
tree.getRootNode().expand();
* </code></pre>
* <p>The example above would work with a data packet similar to this:</p><pre><code>
[{
"text": "adapter",
"id": "source\/adapter",
"cls": "folder"
}, {
"text": "dd",
"id": "source\/dd",
"cls": "folder"
}, {
"text": "debug.js",
"id": "source\/debug.js",
"leaf": true,
"cls": "file"
}]
* </code></pre>
* <p>An example of tree within a Viewport:</p><pre><code>
new Ext.Viewport({
layout: 'border',
items: [{
region: 'west',
collapsible: true,
title: 'Navigation',
xtype: 'treepanel',
width: 200,

}]
});
