/*! - * Ext JS Library 3.3.1 - * Copyright(c) 2006-2010 Sencha Inc. - * licensing@sencha.com - * http://www.sencha.com/license - */ -/** - * @class Ext.tree.TreePanel - * @extends Ext.Panel - *The TreePanel provides tree-structured UI representation of tree-structured data.
- *{@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.
- *A TreePanel must have a {@link #root} node before it is rendered. This may either be - * specified using the {@link #root} config option, or using the {@link #setRootNode} method. - *
An example of tree rendered to an existing div:
- *-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(); - *The example above would work with a data packet similar to this:
- *-[{ - "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" -}] - *An example of tree within a Viewport:
