com.smartgwt.client.widgets.tree.TreeNode
Every node in the tree is represented by a TreeNode object which is an object literal with a set of properties that configure the node.
When a Tree is supplied as {@link com.smartgwt.client.widgets.tree.TreeGrid#getData data} to{@link com.smartgwt.client.widgets.tree.TreeGrid}, you can also set properties from {@link com.smartgwt.client.widgets.grid.ListGridRecord} on the TreeNode (e.g. setting {@link com.smartgwt.client.widgets.grid.ListGridRecord#getEnabled enabled}:false on the node).
