Thanks for your answer, but that dosen't work either:

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

class Test extends JFrame {
    Test() {
    addComponentListener(new ComponentAdapter() {
        public void componentResized(ComponentEvent e) {
           if ( getSize().width != 200 || getSize().height != 100 ) {
            System.out.println("Resize to 200x100");
            setSize( 200, 100 );
           }
        }
       });
    }
    public void paint( Graphics g ) {
    g.drawString( "A test string", 50, 75);
    }

    public static void main( String args[] ) {
    JFrame f = new Test();
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setLayout( null );
    f.setSize( 200, 100 );
    f.setVisible( true );
    }
}

I was absolutely certain that I'd run across this before and not been
able to make it work correctly.  Hmm.  Looks like Andrew solved the
problem.

Thanks for your answer to the above question.  This question
unfortunately is a simplification of what I actually want.
Resizing was an important part of the question.  Now I try
to be precise and short (excuse my english):

- I need a Frame where I can pixelwise draw to, thus no
  automatic layout manger/manging.

- There is a minimum frame size, a maximum Frame size
  and if the user resizes the frame there is a "best
  fitting" frame size due to the user resizing.  That
  means that the programm can't necessary full fill the
  users desired size but it tries to be as close as
  possible.
  The minimum and maximum frame size can change while
  using the software caused by changing the user settings
  (or changing the screen resolution).

Thus my paint method checks whether the resolution
has changed, whether the frame size has changed,
or whether the user settings have changed, since
the last call of paint.  If so the gui is newly
calculated which leads to a frame size that needs
to be set.  How can I set it?  I belief that I can't
calculate the needed size  outside the paint method,
since I need a graphic context to do so?

Thanks a lot for any further help.

Hm, wouldn't the code, placed into "componentResized(ComponentEvent e)"
event handling, be on a place before I call paint?

That's probably what I was thinking of.  You just can't get rid of that
snap back effect in trying to set a maximum size.  

At least I believe that's where we left it that last time this topic came
up.
