implements PolyTreeExpansionListener, PolyTreeWillExpandListener, java.awt.event.ActionListener, javax.swing.event.ListSelectionListener

Sample application using PolyTreeTable, rendering and editing the filesystem (although most filesystems are not polyhierarchies).

This sample demonstrates how to use methods and callbacks of polytreetable. It lets insert new files, remove and rename existing files, and shows how to persist and restore expansion and focus state of the view. It lets change the look and feel and the Component orientation.

The nested class FileTreeTableUserObject implements the polytree file node object. It tries to catch multiple parents by testing if a file is a link (this will work on UNIX only).
