Adding method- JInternalFrmeBorder stays Invisible

Question

Hi all
First of all, excuse my terrible english, but I need profi-help =) and in german Java-Forums(the 3 or 4 =)) I got no answere since 3 days =(.
My prob, I did a GUI with DesktopPane and JInternalFrame and everything was great untill I added some painting-methods -(Check Code for the "HERE-markings")
to it, since that moment the JinternalFrames stood invisible, also the standardButtons for closing,maximize...(all setMax.Vis.Icon(true) ) ,
But I am able to paint my rectangle f.e.
-is it possible that one of the Layers of the DesctopPane is in Front???
-or maybe I need to call the borders???--checked already total-InnerFrames for, how to...
-do I paint at the location of the InternalFrames, but, to DesktopPane???
class DesktopFrame extends JFrame
     private JDesktopPane desk;
     public DesktopFrame()
          super("Desktop-Frame");
          this.desk = new JDesktopPane();
          desk.setDesktopManager(new DefaultDesktopManager());
          setContentPane(desk);
     public void addChild(JInternalFrame child, int PoSx, int PoSy, int SiZx, int SiZy)
          child.setLocation(PoSx, PoSy);
          child.setSize(SiZx, SiZy);
          //child.setDefaultCloseOperation(JInternalFrame.DISPOSE-ON_CLOSE);
          desk.add(child);
          child.setVisible(true);
class ChildFrame extends JInternalFrame
//All the annoying painting stuff =) XXX HERE -HERE XXX
     public ChildFrame(String title)
          super("Watch " + title, true, true);
          setIconifiable(true);
          setMaximizable(true);
          setBackground(Color.black);
public class Something
     public static void main(String[] args)
          DesktopFrame desktop = new DesktopFrame();// create Desktop
          desktop.setVisible(true);
//position, size
          desktop.addChild(new ChildFrame("1 Title" ), 160, 010, 600, 350);
What I am doing wrong???
To me , I have a few difficulties with learning by tutorials, I do things at comp by examples, since 18 years,so plz,
-if it is possible try to help by Code-Snippets...(the farer I get, the less cool Snippets I find =( )
I am quiet new to real-programming, since before I only did some scripts-Html webstuff...IRC bit CGI, bit C++,and... never was so much involved in stuff like now in Java, btw I hate not to know whats going on, in background =) --> InternalFrames-InnerFrames, ...
before Java I would have done this by 'ctrl'-C and 'ctrl'-V ,
dunno yet, why, but somehow I still like this coffee-stuff =)
I go back watching Germany-Southkorea ,press thumbs
thx

Hey I hope you guys don�t worry we kicked your butts @SoccerC., hehe
Common help me with my prob why do my InternalFrames get Invisible whenever I add methods...
btw, the same problem also appeared when I tried Codes, from different books, not always, but often..
means, Could it be I need to set a special path to Swing (if so, I will get a realy redHead )
I set all the other paths at AutoExec.bat and the 2 paths at UserV.and SystemV. ...
Plz help me I get insane on this...
