tom JList bliver ikke vist i GUI

Jeg ville ellers foretrække gridlayout, men selve griddet ligger jo midt i framen og kan kun få komponenterne til at fylde griddet...dvs det er centreret på framen, hvis den er større end griddet. Men måske jeg ikke kender det layout godt nok

mit problem er nu kun de 2 jlists

gridlayout = GridBagLayout :-)

Jeg tror du kan bruge denne eller modificere den, så den passer til dig.
Kan resizes i højde og bredde.
Har tilladt mig at lave det hele i GridBagLayout.

Håber den holder - jeg evner det ikke bedre !!

kan du ikke fortælle mig istedet, hvad problemet er her:
package com.ftp.gui;

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

public class ProgramFrame extends JFrame
{
  public JTextArea outputArea;
  private JList currentUsers, bannedIps;
 
  private GridBagLayout layout;
 
  public ProgramFrame()
  {
    super( "Test" );
   
    layout = new GridBagLayout();
    getContentPane().setLayout( layout );
    GridBagConstraints gbc;
   
    gbc = createGBC( 0, 0, 1, 1 );
    gbc.fill = GridBagConstraints.BOTH;
    outputArea = new JTextArea();
    JScrollPane pane = new JScrollPane( outputArea );
    add( pane, gbc );
   
    gbc = createGBC( 1, 0, 1, 1 );
    gbc.fill = GridBagConstraints.BOTH;
    currentUsers = new JList();
    add( new JScrollPane( currentUsers ), gbc );   
   
    setDefaultCloseOperation( EXIT_ON_CLOSE );
   
    pack();
    setVisible( true );
//    setExtendedState( MAXIMIZED_BOTH );
  }
 
  private GridBagConstraints createGBC( int x, int y, int width, int height )
  {
    GridBagConstraints gbc = new GridBagConstraints();
 
    gbc.gridx = x;
    gbc.gridy = y;
 
    gbc.gridwidth = width;
    gbc.gridheight = height;
 
    return gbc;
  }

  private void add( JComponent component, GridBagConstraints gbc )
  {
    layout.setConstraints( component, gbc );
    getContentPane().add( component );
  }
}

jeg har fået noget brugbart nu, men jeg kan simpelthen ikke finde ud af, hvad der lige skal gøres, for at de 2 JLists ALTID har samme bredde

Har fået løst det...
