Class DrawingPanel

java.lang.Object
  DrawingPanel

All Implemented Interfaces:

java.awt.event.ActionListener, java.util.EventListener

public class DrawingPanel
extends java.lang.Object
implements java.awt.event.ActionListener

The DrawingPanel class provides a simple interface for drawing persistent images using a Graphics object. An internal BufferedImage object is used to keep track of what has been drawn. A client of the class simply constructs a DrawingPanel of a particular size and then draws on it with the Graphics object, setting the background color if they so choose. To ensure that the image is always displayed, a timer calls repaint at regular intervals.
