Add a complex image in the panel, with buttons around it in one customized user interface

  1. Use a 3x3 GridLayout
  2. For each of the 9 cells get a subimage:
  • For every second component, add a label with the subimage.
  • For every other component, add a JButton from which the space is removed. Use the subimage as icon, but you'll need alternate icons to indicate focus, activation etc. This example puts a red border around the 'pressed' icon.

                Image icon = bi.getSubimage(jj, ii, step, step);

                    button.setActionCommand("" + count);

                        System.out.println(ae.getActionCommand());

        JPanel center = new JPanel(new GridBagLayout());
        center.setBackground(Color.BLACK);
        center.add(p);

    public static void main(String[] args) throws Exception {
        URL url = new URL("http://i.stack.imgur.com/SNN04.png");
        final BufferedImage bi = ImageIO.read(url);
        SwingUtilities.invokeLater(() -> {
            new CompassButtons(bi);

}

1) you have to prepare the Icons before and for every 5 JButtons (event here came from ButtonModel)

  • basic Icon without Focus

  • Icon for isRollover()

  • Icon for isPressed()

2) how to set Icons and to remove all "balast" from JButton

3) put these 5 JButtons to the JPanel with painted circles (RemoteSet)


Starting from this example, I got a start by changing MoveButton like this:

this.setBorderPainted(false);

You could give ControlPanel a Custom Layout Manager. I'd also add a background image and some kind of visual feedback based on the ButtonModel state, as suggested here.
