Hello!

I've got a problem. Please look at the code below. When I use rigidarea to
spearate buttons, no matter how large is the frame, buttons are separated
properly. But when I use vertical and horizontal struts vertical space
between buttons is changing along with the frame size. What is the reason?
Thanks for any help.

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

public class klasa {
   public static void main(String[] args) {
       Ramka r = new Ramka();
       r.setSize(200,200);
       r.pack();
       r.setVisible(true);
   }
}

class Ramka extends JFrame {
   public Ramka() {
       Container c = this.getContentPane();
       Box L1 = Box.createHorizontalBox();
       Box L2 = Box.createHorizontalBox();
       Box L = Box.createVerticalBox();
       L1.add(new JButton("test1"));
       //L1.add(Box.createRigidArea(new Dimension(5,0)));
       L1.add(Box.createHorizontalStrut(10));
       L1.add(new JButton("test2"));
       L1.setAlignmentX(Component.LEFT_ALIGNMENT);        
       L2.add(new JButton("test3"));
       //L2.add(Box.createRigidArea(new Dimension(5,0)));
       L2.add(Box.createHorizontalStrut(10));
       L2.add(new JButton("test4"));
       L2.setAlignmentX(Component.LEFT_ALIGNMENT);
       L.add(L1);
       //L.add(Box.createRigidArea(new Dimension(0,5)));
       L.add(Box.createVerticalStrut(10));
       L.add(L2);
       c.add(L);
   }
}
