problems w/ JCheckBox's and TableModel

[Steve Kiernan]

I need some guidance in figuring out this little problem. I have a Scrollable JTable which needs to obtain data from a GUI that I've created. The GUI contains three different groups of checkbox's. I can't figure out what method to use to get the selected checkbox's in each group. I've tried using getSelection() with no avail. Please any examples or tips would be greatly appreciated.

Hi Steve,
I usually use the action command to figure out which is set. You can do something like the code below.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class RadioTest extends JFrame
{
  JRadioButton b1, b2, b3, b4;
  ButtonGroup bg;
  public RadioTest()
  {
    super( "RadioBox Test" );
    bg = new ButtonGroup();
    b1 = new JRadioButton( "One", true );
    b2 = new JRadioButton( "Two" );
    b3 = new JRadioButton( "Three" );
    b1.setActionCommand( "One" );
    b2.setActionCommand( "Two" );
    b3.setActionCommand( "Three" );
    bg.add( b1 );
    bg.add( b2 );
    bg.add( b3 );
    bg.add( b4 );
    JPanel p = new JPanel();
    p.add( b1 );
    p.add( b2 );
    p.add( b3 );
    Container cont = getContentPane();
    cont.add( p, BorderLayout.NORTH );
    p = new JPanel();
    JButton b = new JButton( "Print" );
    b.addActionListener(
      new ActionListener()
      {
        public void actionPerformed( ActionEvent ae )
        {
          System.out.println( bg.getSelection().getActionCommand() );
        }
      });
    p.add( b );
    b = new JButton( "Quit" );
    b.addActionListener(
      new ActionListener()
      {
        public void actionPerformed( ActionEvent ae )
        {
          System.exit( 0 );
        }
      });
    p.add( b );
    cont.add( p, BorderLayout.SOUTH );
  }
  public static void main(String[] args) 
  {
    RadioTest rt = new RadioTest();
    rt.setSize( 300, 500 );
    rt.setVisible( true );
  }
}

Regards,
Manfred.
