BSTTreeJPanel

public class TreeJPanel

extends DrawingJPanel

implements OptionListener, java.awt.event.ActionListener, TreeMessageListener

This class provides the panel for a Tree. It keeps the graphics for drawing the tree and the image for redrawing. It also keeps a timer for the animation and all changes to the tree proceed through the panel. This is a class that is extended for each specific tree.
