public abstract class ShapeButton

extends Canvas

implements MouseListener

A on/off button that displays a Shape.

This class is implemented to be usable in Java 1.1 applets, and so follows an AWT-only requirement
(no Swing, Java2D, geom, or Java 2 feature)

Because of the graphics to be drawn on it, this button inherits from java.awt.Canvas and not from java.awt.Button
(of which the peer cannot be overwritten on every platform)
