I am designing a Tree for use in the EXTJS4.  In my tree I will be adding new nodes to the Tree. The basic Sencha Tree example is quite the simple case.

The tree I am defining makes use of the Tree Panel as follows:

Ext.define(‘my.view.FolderList’, {
extend : ‘Ext.tree.Panel’

Just like the example, I define my first column as a ‘tree column’:

xtype: ‘treecolumn’, //this is so we know which column will show the tree

Some methods of the Tree Panel which will be usefull:

Via the getSelectionModel()  which returns Ext.selection.Model , you can get:!/api/!/api/!/api/Ext.tree.Panel-method-expandPath!/api/”>
