Repaint funktioniert nicht über JViewPort

[test0ster0n]

Hallo,

2 Dinge funktionieren nicht richtig in meiner GUI.

Habe hier mal die ausführbare .jar geuppt.

http://www.sendspace.com/file/mx93za

1. schreibe ich viel Text oder kopiere diesen in die JTextarea, markiere Text und fahre dabei hoch/runter mit der Maus verändert sich die Größe der Komponenten über/unter der JTextArea mit dem selektierten Text darin ????


2. der gezeichnete String z.B. "your Message" wird nicht richtig repainted wenn man text einfügt/scrollt mit selektiertem text usw.

Der Source Code ist in der .jar mitdrin, einfach entpacken.

Kann mir jemand Tips geben zu obigen Problemen?

so ich habe nochmals den java code zum gleich lesen hier angehängt:


weiterhin habe ich 2 screenshots gemacht zum Vergleich, dass Ihr seht was ich mit der sich veränderten GUI meine...

	  super("test");  
	  
	  final RP rP = new RP(); 
	 
      jtp.addTab("test", rP);   
        
      add(jtp);      
      setResizable(false);      
      setSize(400,400);
      setLocationRelativeTo(null);
