hi !

I've created a special window (transparent), but I've got problem : when I
add JLabels to it, they don't appear in the window !

Here's my code (yhe code for the transparent window isn't optimised yet,
that's just a short version, not too long, to understand the basic
mechanism) :

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

public class TransparentWindow extends JWindow implements
MouseMotionListener, FocusListener {

 JPanel contentPane;
 JLabel label1 = new JLabel("Hello !");

 Image     img,tim;
 Graphics  tig;
 Point     mp;
 Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
 

 public TransparentWindow() {

       setBounds((int)(d.getWidth()-475)/2,0,475,100);
       capture();
       
       contentPane = (JPanel) getContentPane();
       contentPane.setLayout(new FlowLayout(10,10,FlowLayout.CENTER));
       contentPane.add(label1);
               
       addMouseMotionListener(this);
       addFocusListener(this);

       setVisible(true);
 }

       
       public void focusGained(FocusEvent fe)
       {
       Point p = getLocation();
       setLocation(11111,0);
       capture();
       setLocation(p);
       }
       
       public void focusLost(FocusEvent fe)
       {
       }
       
       public void capture()
       {
       try {
               Robot     r    = new Robot();
               Rectangle rect = new Rectangle(0,0,d.width,d.height);
               img = r.createScreenCapture(rect);
       }
       catch(AWTException awe) {
               System.out.println("robot excepton occurred");
       }
       }
       
       public void mouseDragged(MouseEvent m)
       {
            Point p = m.getPoint();
            int x = getX()+p.x-mp.x;
            int y = getY()+p.y-mp.y;
            setLocation(x,y);
            Graphics g = getGraphics();
            paint(g);
       }
       
       public void mouseMoved(MouseEvent m)
       {
             mp = m.getPoint();
       }
       
       public void paint(Graphics g)
       {
       if (tim == null)
       {
           tim = createImage(getWidth(),getHeight());
           tig = tim.getGraphics();
       }
       tig.drawImage(img,0,0,getWidth(),getHeight(),
getX(),getY(),getX()+getWidth(),getY()+getHeight(),null);
       tig.setColor(new Color(0,0,0,128));
       tig.fillRoundRect(0,0,getWidth(),getHeight(),100,120);
       g.drawImage(tim,0,0,null);
       }
       
       public void cupdate(Graphics g)
       {
                this.paint(g);
       }
       

 public static void main (String[] args)  
 {
       new TransparentWindow();
 }

}
