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