All Implemented Interfaces:

java.awt.event.KeyListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible

public class ColorTableCanvas
extends javax.swing.JPanel
implements java.awt.event.MouseMotionListener, java.awt.event.MouseListener, java.awt.event.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.
