Size of JFrame and JPanel

[Juhan Voolaid]

Hi

I have Jframe that has a borderlayout. In south there is small jpanel with some information text and in center is big JPanel where the game is running.

Proble is that i want the JPanel in center to have size of lets say 800*600 and JFrame would set its size automatically, so that the 2 JPanels fit perfectly. And JFrame will not have any extra space anywhere.

I don't know how to do that.

Try this (I've used North/Center instead of Center/South)

import java.awt.*;
import javax.swing.*;
 
class Testing extends JFrame
{
  public Testing()
  {
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    JPanel jp1 = new JPanel();
    jp1.setPreferredSize(new Dimension(800,600));
    jp1.setBorder(BorderFactory.createLineBorder(Color.black));
    JPanel jp2 = new JPanel();
    jp2.setPreferredSize(new Dimension(800,100));
    jp2.setBorder(BorderFactory.createLineBorder(Color.black));
    getContentPane().add(jp1,BorderLayout.NORTH);
    getContentPane().add(jp2,BorderLayout.CENTER);
    pack();
  }
  public static void main(String[] args){new Testing().setVisible(true);}
}
