+ * @class Ext.tree.TreePanel
+ * @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,

+ }
+ }, {
