JDesktopPane JPanel Trouble

[AndyHollywood]

Hello

I have a Jpanel which has some graphics being drawn in it, just lines etc..

I have a JDesktopPane which has INternal Frames in it, and i want the JPanel to be like a background on the JDesktopPane, how would i go about doing this?

Cheers in advance, is been foxing me for days this problem

Cheers

One way to do it is :

import java.awt.*;
import javax.swing.*;

public class Desktop extends JFrame {

  private Image image;

  public static void main(String[] args) {
    Desktop example = new Desktop("Title");
    example.doIt();
  }

  public Desktop(String title) {
    super(title);
  }

  public void doIt() {
    setSize(500,500);
    setVisible(true);
    Container cp = getContentPane();
    JDesktopPane dp = new MyDesktopPane();
    cp.add(dp,BorderLayout.CENTER);
    JInternalFrame intf = new JInternalFrame("Internal Frame",true,true,true,true);
    intf.setBounds(10,10,250,100);
    intf.setVisible(true);
    dp.add(intf);
  }

  public Image getImage() {
    if (image == null) {
      try {
        image = ImageLoader.loadImage("D:/images/splash.jpg");
      } catch (InterruptedException e) {
      }
    }
    return image;
  }

  public class MyDesktopPane extends JDesktopPane {

    public MyDesktopPane() {
      super();
    }

    public void paintComponent(Graphics g) {
      super.paintComponent(g);
      // You can replace the next line with your drawing methods (or save your drawing as a jpg, ...)
      g.drawImage(getImage(), 10,10,null);
    }
  }

}

=====================================

import java.awt.*;

public class ImageLoader extends Component {

  private static ImageLoader imageLoader;

  static {
    imageLoader = new ImageLoader();
  }

  private ImageLoader() {
    super();
  }

  public static Image loadImage(String imageName) throws InterruptedException {
    Image image = Toolkit.getDefaultToolkit().getImage(imageName);
    MediaTracker tracker = new MediaTracker(imageLoader);
    tracker.addImage(image,0);
    tracker.waitForID(0);
    return image;
  }
}
