18.8 java.awt.Canvas (JDK 1.0)

This class is a Component that does no default drawing or event handling on its own. You can subclass it to display any kind of drawing or image, and to handle any kind of user input event. Canvas inherits the event handling methods of its superclass. In Java 1.1, you can also subclass Component directly to create a "lightweight component," instead of having to subclass Canvas.

public class Canvas extends Component {
    // Public Constructor
        1.1 public Canvas();
    // Public Instance Methods
            public void addNotify();  // Overrides Component
            public void paint(Graphics g);  // Overrides Component
