Thanks in advance,

I'm trying to put a JCheckBox (and will add listener to it) into a JTable cell.

Can someone take a look at this and tell me where I'm going wrong?

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.event.*;
public class Test extends JFrame
{  Container cp = getContentPane();
  JTable table = null;
  Object columnNames[] = {"Col1", "Col2", "Col3", "Col4"};
  Object cell[][] = null;
  Test()
  {
     table = new JTable();
     cell = new CheckboxRenderer[1][4];
     for (int row=0; row < 1; ++row)
     {
        for (int col=0; col < 4; ++col)
        {
           cell[row][col] = new CheckboxRenderer(table, row, col);
           table.setDefaultRenderer(
((JCheckBox)cell[row][col].getCheckbox()).getClass(),cell[row][col]);
        }
     }
     cp.setLayout(new BorderLayout());
     cp.add( table = new JTable(cell, columnNames), BorderLayout.CENTER);
     pack();
     setVisible(true);
  }

  public static void main(String args[]) { new Test(); }
}

class CheckboxRenderer extends JPanel implements TableCellRenderer
{
  public JCheckBox cb = new JCheckBox("",false);
  protected JTable table = null;
  protected int row = 0;
  protected int col = 0;
  public JCheckBox getCheckbox() { return cb; }
  CheckboxRenderer(JTable table, int row, int col)
  {
     this.table = table;
     this.row = row;
     this.col = col;
     setLayout(new FlowLayout());
     add(cb);
  }
  public Component getTableCellRendererComponent(JTable table,
                   Object value, boolean isSelected, boolean hasFocus,
                   int row, int column)
  {
      return this;
  }

}
