All Implemented Interfaces:

java.lang.Comparable
```
public class TreeNode
extends java.lang.Object
implements java.lang.Comparable
```
The TreeNode is the class used by the TreeBox to identify a single node.

Users create an Array of TreeNode objects and pass the corresponding Enumeration to the TreeBox. The enumeration represents a single level in a hierarchal tree.

The TreeNode class is also used by the TreeView to identify a single node.

In either case users populate the TreeView with TreeNodes to render a tree. The TreeView has a root node by default to which the user can add more TreeNodes as children which themselves can have children and thus renprest a tree structure.

For each node, the user needs to specify:
- Its display name (as displayed by the browser).
- Its ID (to uniquely identify the node).
- The associated WebEvent (to expand the node).
- If it's a leaf (those nodes that are leaf may not be expanded).
When a node is expanded, the associated WebEvent is executed using the iFrame technology. With this, the tree can be dynamically populated without refreshing the whole page.
