Graphics 2d Object and Scroll Bar Issue

[J Cleary]

Hello all, i have a desperate problem please, any ideas would be appreciated.
I want to know how to scroll a screen with a set of rectangles drawn using the java 2d approach (Graphics g)? i have the scroll bar displayed but it does not work.
i have exhausted my ideas.
Thanks

Here is one example.

Is this what you are looking for?

import java.awt.*;
import javax.swing.*;
 
public class ScrollingApplet extends JApplet {
 
   private JScrollPane createJScrollPane(Component component,
                                         int width,
                                         int height,
                                         int xlocation,
                                         int ylocation) {
      JScrollPane pane = new JScrollPane(component);
      pane.setSize(width,height);
      pane.setLocation(xlocation,ylocation);
 
      return(pane);
   }
 
   public class MyPanel extends JPanel {
 
      public MyPanel(int width,
                     int height) {
         super(true);
 
         setPreferredSize(new Dimension(width,height));
      }
 
      public void paint(Graphics g) {
         g.clearRect(0,0,getWidth(),getHeight());
 
         super.paint(g);
 
         Graphics2D g2 = (Graphics2D)g;
 
         g.setColor(Color.red);
 
         g2.fill3DRect(10,800,200,200,true);
 
         setPreferredSize(new Dimension(getWidth(),1100));
 
         revalidate();
      }
 
   }
 
   public void init() {
      Container container = getContentPane();
 
      container.setLayout(null);
 
      container.setBackground(Color.white);
 
      container.add(createJScrollPane(new MyPanel(getWidth(),getHeight()),
                                      getWidth(),getHeight(),
                                      0,0));
   }
 
}
