How to put a jpopup menue in a cell of jtable

Question

Hello,
I want to make a jtable in which I want in one of the columns each cell when clicked(with right button) to pop up a jpopu menu with 3 actions. First I thought to make it with combobox but because I want to be activated with right button and then with the left i have changed my mind to jpopup menu.
Can you tell me what kind of render and editor to use? I will be very grateful if you can send me some examples because I am new to the swing.
Thanx,
Miroslav

You probably want to add a mouse listener to the JTable itself.
There is some sample code below. It adjusts the location of the
menu, and it's source component so that the menu can opperate
on the proper object, rather than the source of the event.
On your table add the menu as follows:
    table.addMouseListener(new PopupMouseListener(menu));You will have to decode the location to determine which column
the "Right Click" occurred on. You may then have to decode the
menu you want, (if you have different menus for different
columns/cells).
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
import com.ovotron.util.Debug;
public class PopupMouseListener extends MouseAdapter {
    private JPopupMenu menu    = null;
    private Component  invoker = null;
    public PopupMouseListener(JPopupMenu menu) {
        super();
        this.menu = menu;
    public PopupMouseListener(JPopupMenu menu, Component invoker) {
        this(menu);
        this.invoker = invoker;
    public void mousePressed(MouseEvent e) {
         int mod = e.getModifiers();
         if ((mod & MouseEvent.BUTTON3_MASK) == MouseEvent.BUTTON3_MASK) {
             if (menu == null) {
                 return;
             int       x     = e.getX();
             int       y     = e.getY();
             Component comp  = (Component)e.getSource();
             if (invoker != null) {
                 // Event (X,Y), are relative to the source, need to
                 // re-calculate to be relative to the invoker.
                 Point src = comp.getLocationOnScreen();
                 Point loc = invoker.getLocationOnScreen();
                 x = x - (loc.x - src.x);
                 y = y - (loc.y - src.y);
                 comp = invoker;
             menu.show(comp, x, y);
}
