Keeping the Menu visible after an action is performed.

Question

I'm trying to capture the right click events on JMenuItems and display popup menu options for the selected JMenuItem. I've managed to capture the right click and get the Popup ready; however, when the right click is performed, or any other type of "action", the Menu dissappears. How can I keep the menu visible?

Answer 1

The following code should prevent the menu from closing on a right click:
     class RightClickJMenuItem extends JMenuItem
          public RightClickJMenuItem(String str)
               super(str);
          protected void processMouseEvent(MouseEvent e)
               if (e.getModifiers() != MouseEvent.BUTTON3_MASK)
                    super.processMouseEvent(e);
     }
