You can no longer clear the clipping rectangle. That way applets can't
paint outside their bounds. If you want multiple clipping rectangles
within your applet, then use the Graphics.create(x, y, w, h) method to
create a "sub-Graphics" object...
What you want to do is to take the graphics that was handed in and do:
public void paint(Graphics g) {
Graphics ng = g.create(10, 10, 30, 30);
ng.drawSomething();
ng.dispose();
ng = g.create(50, 50, 30, 30);
ng.drawSomethingElse();
ng.dispose();
}
