I tried this with no luck
import java.awt.Dimension;
import java.beans.PropertyVetoException;
import javax.swing.JButton;
import javax.swing.JDesktopPane;
import javax.swing.JFrame;
import javax.swing.JInternalFrame;
import javax.swing.JPanel;
import javax.swing.event.InternalFrameAdapter;
import javax.swing.event.InternalFrameEvent;
public class DesktopPane extends JDesktopPane {
     JInternalFrame jif;
     JPanel p1;
     public DesktopPane() {
          p1 = new JPanel();
          JButton b = new JButton("Test");
          p1.add(b);
          jif =  new JInternalFrame("test", true, false, true, true);
          jif.getContentPane().add(p1);
          jif.setVisible(true);
          jif.setSize(new Dimension(200,200));
          jif.addInternalFrameListener(new InternalFrameAdapter() {
               public void internalFrameOpened(InternalFrameEvent e) {
                    System.out.println("ere");
                    try {
                         jif.setIcon(true);
                    } catch (PropertyVetoException e1) {
                         // TODO Auto-generated catch block
                         e1.printStackTrace();
          this.add(jif);
     public static void main(String[] args) {
          JFrame f = new JFrame();
          f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          f.getContentPane().add(new DesktopPane());
          f.setSize(400,400);
          f.setVisible(true);
}any other ideas??
thanks
