public class FrameCanvas
extends JDrawingCanvas
implements DrawingCanvas, ComponentListener, WindowListener

FrameCanvas is an extension of JDrawingCanvas that creates a JFrame and puts a JDrawingCanvas inside. It is provided to make it possible to experiment with creating and manipulating graphical objects on a DrawingCanvas under environments like Dr. Java and BlueJ.
