Whats all this about subclassing Canvas and overriding paint() ? Can I just do a getGraphics() for a component, and draw directly on that?
• A. You can do that, and it might work up to a point (or it might not). A problem arises when the window system wants to refresh that component e.g. because it has been partially obscured and is now revealed. It calls paint(), and paint() has no knowledge of the other g.drawing() you have just done.
