JMenuItems in JPopMenu are not highlighted

Question

Hi,
In my application I have a JPopMenu added to a JPanel when I right click the JPopMenu appears and you can select JMenuItem's in it, but there is no graphical feedback like in a standard JMenu. I mean when the mouse hovers over a JMenuItem it does not change color/become selected.
I had to extend the MouseAdapter class as shown
                 public void mouseClicked(MouseEvent e){
                * A workaround because e.isPopUpTrigger is
                * not recognising that right click is a popup trigger
                         * NOTE: this is system(mouse) specific
               if(e.getButton() == MouseEvent.BUTTON3){
                    //set the location of the popup menu
                    pop.setLocation(e.getX(), e.getY());
                    //make the popup menu visible
                    pop.setVisible(true);
               else{
                    //if the popup menu is visible
                    if(pop.isVisible()){
                         //hide menu
                         pop.setVisible(false);
          private void checkTrigger(MouseEvent e){
               if(e.isPopupTrigger()){
                    System.out.println("Is Trigger");
          }Also does anyone know why e.isPopupTrigger is returning false when I right click, I am using windows so I assume this should work.

Hi there
I had the same trouble with the color of the items in the popup menu. To fix it, I made a component that extends the JMenuItem called JMouseMenuItem that I added to the popup. Then in the JMouseMenuItem, I have a MouseListener which does this...
public void mouseEntered(MouseEvent e){
          setBackground(UIManager.getColor("MenuItem.selectionBackground"));
          setForeground(UIManager.getColor("MenuItem.selectionForeground"));
     public void mouseExited(MouseEvent e){
          setForeground(Color.BLACK);
          setBackground(UIManager.getColor("Panel.background"));
     }[\code]
It works great now.
