I am stuck....and I am sure it is simple.  Basically I have a
panel that has some stuff in it.  I want to have another panel (kind
of an overview) that shows everything in the main panel.

So I have something like:
           mainPanel = new JPanel() {
               public void paintComponent(Graphics g) {
                   super.paintComponent(g);
                   Rectangle r = mainPanel.getBounds();
                   BufferedImage bi = new BufferedImage(r.width,
r.height, BufferedImage.TYPE_INT_ARGB);
                   Graphics biG = bi.createGraphics();
                   super.paint(biG);
                   myP.setImage(bi);
               }
           };

   public static class MyPanel extends JPanel {
       private BufferedImage bi;

       public MyPanel() {
           this.bi = new BufferedImage(1, 1,
BufferedImage.TYPE_INT_ARGB);
       }

       public void setImage(BufferedImage bi) {
           System.out.println("...new image");
           this.bi = bi;
           this.repaint();
       }

       public void paintComponent(Graphics g) {
           super.paintComponent(g);
           System.out.println("bi: " + bi.getWidth() + ", " +
bi.getHeight());
           Graphics2D g2 = (Graphics2D) g;
           g2.drawImage(bi, 0, 0, bi.getWidth(), bi.getHeight(),
null);
       }

     myP = new MyPanel();

so mainPanel has all the stuff, and myP should show it as well....but
it's not working.

any ideas?
