  wheels.etc.AbstractGraphic

All Implemented Interfaces:

CustomGraphic

Direct Known Subclasses:

Shape

public abstract class AbstractGraphic

extends Object

implements CustomGraphic

Abstract class implementing CustomGraphic interface. For convenience, defines all the mouse interaction methods to do nothing so they don't all have to be defined every time a class implementing CustomGraphic is created. All subclasses must implement paint(java.awt.Graphics2D) and contains(java.awt.Point)!
