Hello,
i've got a problem. I want to scroll a picture which is in a
JScrollPane and this JScrollPane is a tab of a JTabbedpane.
Here is a part of the source code:

....
private JTabbedPane JMainTab = new JTabbedPane();
private JPanel plInfo = new JPanel();
private JPanel plZustand = new JPanel();
public JScrollPane Scroller = new JScrollPane();
public ImagePanel IP = new ImagePanel("dcschutz.jpg");

Scroller.add (IP);

JMainTab.addTab("Informationen",null,plInfo,"Informationen zum
geladenen Plan.");
JMainTab.addTab("Plan",null ,Scroller,"Den geladenen Plan anzeigen");
JMainTab.addTab("Zustände",null, plZustand,"Einzelne Zustände laden
und speichern");
cp.add(JMainTab);

....

the ImagePanel class

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

public class ImagePanel extends JPanel {
 protected BufferedImage     iImage        = null;
 protected int               iImageWidth   = 0;
 protected int               iImageHeight  = 0;

 public ImagePanel(String imageName) {
   super(false);
   setBackground(Color.black);
   iImage=loadImage(imageName);
   if (iImage!=null) {
     iImageWidth=iImage.getWidth();
     iImageHeight=iImage.getHeight();
     setPreferredSize(new Dimension(iImageWidth,iImageHeight));
   }
 }

 public void paintComponent(Graphics g) {
   super.paintComponent(g);
   Insets insets=getInsets();
   if (iImage!=null) {
     g.drawImage(iImage,insets.left,insets.top,null);
   }
 }

 private BufferedImage loadImage(String fileName) {
   Image image=Toolkit.getDefaultToolkit().getImage(fileName);
   MediaTracker mt=new MediaTracker(this);
   mt.addImage(image,0);
   try {
     mt.waitForID(0);
   }
   catch (InterruptedException ie) {
     return null;
   }
   if (mt.isErrorID(0)) return null;
   BufferedImage bufferedImage = new BufferedImage(
     image.getWidth(null), image.getHeight(null),
     BufferedImage.TYPE_INT_RGB);
   Graphics2D g2d=bufferedImage.createGraphics();
   g2d.drawImage(image,null,null);
   return bufferedImage;
 }

}

when i start the programm and switch to the "Plan"-tab, i can see
nothing. But when I replace the JScrollPane with the ScrollPane from
AWT it runs. but I have to use swing because the items in the menubar
are under the Scrollpane.

could somebody help me???
