I have a doubt. Can i place a panel on top of the image in the frame?

I have a JFrame where i want the image to be displayed... and i have a JPanel where i want it to be displayed but on top of the image. I am talking about the skin of the GUI...   In VC++, you can do that.. is there a way to do in java??

Thanks in advance

If you want to float components over the image just override paintComponent, being careful to call super.paintComponent

public void paintComponent(Graphics g) {
      super.paintComponent(g);
      // call drawImage here
}

You'll still be able to add components leaving the image there

If you want the image drawn behind the panel, you need to override paintComponent() (see CEHJ's comment) in your JFrame instance.

You can't do that actually - JFrame has no paintComponent. Easiest to add another JPanel to the frame and then place the final one on that

Oh, my bad.

rampriya_sb, recap of information so far:
Set BorderLayout as your layout manager for the JFrame's content pane
Override paintComponent in a subclass of JPanel, in order to paint the image, as described above
Add an instance of the JPanel described above to the BorderLayout.CENTER of the JFrame

>>Set BorderLayout as your layout manager for the JFrame's content pane...

Well of course, it's still not clear what the intention is, so this is probably a little bit too assumptive ;-)

possibly, but not if he wants the image to cover the complete area of the JFrame

As suggested, i overrode paintComponent method and put the image

class TestPanel extends JPanel
{

JPanel pnlAnotherPanel;
public TestPanel()
{
    pnlAnotherPanel = new JPanel();
    pnlAnotherPanel.setBackground(Color.white);
    pnlAnotherPanel.setBounds(new Rectangle(30,30,60,80));
    this.add(pnlAnotherPanel,null);
}

public void paintComponent(Graphics g)
{
  super.paintComponent(g);
  Image img=Toolkit.getDefaultToolkit().getImage("testimg.jpg");
  g.drawImage(img,0,0,this);
}
}

When i try to put this JPanel class to the Frame and try to runthe program, only the image is displayed and not the panel(pnlAnotherPanel)..... so what shud i do for that? i tried setting the panel to opaque, but didnt help...

Theres no need to override paintComponent, just add your panel to whatever component is displaying your image.

eg.

JLabel back = new JLabel(image);
JPanel panel = new JPanel();
back.add(panel);

If you instead want the panel to float above your existing component hierarchy then add the panel to the glass pane or a layered pane.
