Shows how to use the UndoManager with a list...  

Basically, each operation the user performs has to be a class that extends AbstractUndoableEdit.  It is up to you to provide the implementations that say whether an operation can be undone, what happens when it is undone, and how it can be redone...

The applet doesn't work on that page, but the code is valid :-)
