Example 2 Jlists in a JDialog

[Kristof Camelbeke]

Hello,
I'm trying to find an example (code) of two Jlists inside a JDialog in which the user can select items from one Jlist (which contains all the data) and move it to the other Jlist by means of a button click.
Is there anybody who knows where I can find this ?
Any help is appreciated...

Here's something I put together quickly that should give you the basic idea:

 
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.util.*;
public class JListTest extends JFrame {
    
    JList list1, list2;
    Vector v1;
    
    /**
     * Description
     */
    public JListTest() {
        super();
        
        v1 = new Vector();
        v1.add( "Item1" );
        v1.add( "Item2" );
        v1.add( "Item3" );
        
        list1 = new JList( v1 );
        list2 = new JList( new DefaultListModel() );
        
        JButton move = new JButton( ">>" );
        move.addActionListener( new ActionListener() {
            public void actionPerformed( ActionEvent e ) {
                if ( list1.getSelectedIndex() != -1 ) {
                    ((DefaultListModel)(list2.getModel())).addElement( 
                        v1.get( list1.getSelectedIndex() ) );
                }
            }
        });
        
        JPanel panel = new JPanel();
        panel.setLayout( new GridLayout( 1, 3 ) );
        panel.add( new JScrollPane( list1 ) );
        panel.add( move );
        panel.add( new JScrollPane( list2 ) );
        
        getContentPane().add( panel );
        setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        
        pack();
        setVisible( true );
    }
    
    public static void main( String args[] ) {
        new JListTest();
    }
    
}
