JDesktopPane background

Hi,

What I want is a JFrame of size(1024, 768);
i can setJMenuBar of the frame, and then I create a JToolBar and add it to the NORTH of the ContentPane.

I add a JLabel in the CENTER and the label simply contains an image (so it looks as if it is the background).

No i want to add InternalFrame. However they can only be added to a JDesktopPane.
there fore i created a JDesktopPane and set it as the contentPane of the JFrame.

However the layout of the desktopPane is null... if i set it to BorderLayout, then the internal frames dont minimize.
if i let the layout to null, then I cant see the background image, and the ToolBar is not seen also.

So is there any help I can get, so that I may add these things:

1. A JMenuBar.
2. A JToolBar at the NORTH (non-floatable).
3. A Background Image of the entire frame.
4. Internal frames (5 - 10 of them).

Thanks.

A JDeskTopPane is a JLayeredPane.
I guess you can play with the different layers.

see http://java.sun.com/developer/qow/archive/49/index.html

where you can read:

JDesktopPane is a JLayeredPane. Add a JLabel with the ImageIcon using

            desktopPane.add(child, JLayeredPane.FRAME_CONTENT_LAYER)

For setting up a image background,

// Note 11.
JDesktopPane desktop = new JDesktopPane();
JInternalFrame frA = makeInternalFrame();
desktop.add(frA); // Note 12.
getContentPane().add(desktop); // Note 13.
getContentPane().getGraphics().drawImage(---------) // add this line

public MyFrame() {
  super("My Frame");
  desktop = new JDesktopPane();
  desktop.setDragMode(JDesktopPane.LIVE_DRAG_MODE);
  setContentPane(desktop);
 
  desktop.add(new JLabel("Hello, World"), JLayeredPane.FRAME_CONTENT_LAYER);
 
  setDefaultCloseOperation(EXIT_ON_CLOSE);
  setResizable(false); setSize(1024, 768);
  setVisible(true);
}

it isnt showing me Hello, World.
i can add internal frames easily.

JDesktopPane's layout is null.
do I have to setBounds of the JLabel ???
i think that is why it is not showing me.

ok figured my problem.

as the layout of JDesktopPane is null, the added label (or any other component) will not be visible, as its bounds are not set.

thanks anyway.
