public class GuiOutputDevice

extends java.awt.Canvas

implements OutputDevice

Graphics device that displays its contents using a Java AWT component.

A device object from this class has both a graphical object (the contents of the display) and a Java Graphics2d object to do the actual plotting. The class extends Canvas to give access to the range of interaction and control provided by Java's AWT and Swing packages.
