Ok, I'm building a Java App in fullscreen mode. I've got the fullscreen mode working on a JFrame object with a JPanel added to it for content. What I need to know is how to swap the JPanel for a different one without dropping out of fullscreen mode. I suspect this has something to do with the BufferStrategy class, but I can't get it to work.

Here's what I've got so far, with a MyPanel jsut being a simple JPanel with an image and a settable background color. It should show the red one, wait around for a sec, then show the blue one. Currently it jsut shows the red one then a blank screen.

public static void main(String args[]) {
      try {
                GraphicsDevice screen = screenSetup();
            DisplayMode dmode = new DisplayMode(800, 600, 32, DisplayMode.REFRESH_RATE_UNKNOWN);
            JFrame frame = makeFrame();

            MyPanel pan1 = testPanel(Color.RED);
            MyPanel pan2 = testPanel(Color.BLUE);

              Container conpane = frame.getContentPane();
            conpane.add(pan1, BorderLayout.CENTER);

            screen.setFullScreenWindow(frame);
            screen.setDisplayMode(dmode);

            frame.createBufferStrategy(2);
            BufferStrategy bufstrat = frame.getBufferStrategy();
            Graphics g = bufstrat.getDrawGraphics();

            Thread.sleep(6000);
            Rectangle bounds = frame.getBounds();
            javax.swing.SwingUtilities.paintComponent(g, pan2, conpane, bounds);
            bufstrat.show();

      } catch (Exception ex) {
            ex.printStackTrace();
      }
}

Thanx.
