But i use that, but my problem is that whem i click outside the JPopupMenu the doesnt hide.

 trayIcon.addMouseListener(new MouseAdapter() {
            public void mouseReleased(MouseEvent e) {
               
                if (e.isPopupTrigger() == true) {

                    popup.setLocation(e.getXOnScreen()+10,e.getYOnScreen()-170);
                    popup.setInvoker(popup);
                    popup.setVisible(true);

                }else{

                   System.out.println("Else");
                   popup.setInvoker(null);
                   popup.setVisible(false);

                   JOptionPane.showMessageDialog(null,
                    "TrayIcon", "About",
                    JOptionPane.INFORMATION_MESSAGE);


                }
            }
        });

    }

It looks like you're adding/removing things from the pop-up possibly while it is showing. That's going to cause event handling problems (such as a popup that doesn't go away). What you want to do is make sure the menu is only modified when it is not showing.

[macwadu]

Ok but if i hide the popup when is actualized that problem dispears, right?

However i have the same problem that when i click outisde the menu it doesnt desapear.

[doWhile]

Depending upon the behavior you wish, you can hide the JPopupMenu based upon another event, for example MouseEvent.mouseExited.

[macwadu]

Can you give a example of that because i tried and the mouseExited have a problem with popup.addSeparator(); it give distinct events for the before the addseparator and after the separator.

[bilTunDev]

hi there
macwadu , i wonder if you have found a solution; i am having the same probleme here
mouseExited have a problem with addSeparator()
and it's not even a good behavior to hide the popup menu when it exit;
i really prefer to hide it only when user click outside the popup menu area
so if you can help me you are welcome !

[macwadu]

I can solve the problem, and dont have any idea how can it be done, i think this is a bug of the JPopupMenu because in popupmenu it works fine but its not possible to add a icon to the menu.
