Interface DrawingComponent

public interface DrawingComponent

The DrawingComponent holds the drawing editor used by the DrawingApplet.

The DrawingComponent covers the whole content pane of the DrawingApplet. It thus has to provide the user interface elements for saving the drawing and canceling the applet on its own. The DrawingApplet registers with the DrawingComponent as an ActionListener to receive "save" and "cancel" action commands.
