All Implemented Interfaces:

KeyListener, MouseListener, MouseMotionListener, ImageObserver, MenuContainer, Serializable, EventListener, Accessible

public class ColorTableCanvas
extends JPanel
implements MouseMotionListener, MouseListener, KeyListener

This class provides the guts of the color table editor. The actual ColorTableCanvas is a JPanel that draws the color bar in the editor. This class also provides the gui components that are wrapped the canvas itself.
