Adición JPopupMenu a la TrayIcon

Question

Quiero añadir JPopupMenu a la barra de tareas como TrayIcon (es decir systemTray.add(trayIcon)) pero no he encontrado una manera de hacer so.From la docs el constructor de TrayIcon es así:

public TrayIcon(Image image, 
      String tooltip, 
      PopupMenu popup) 

¿Hay alguna manera de que pueda hacer esto?

Answer 1

Usted puede mirar en el tutorial y el ejemplo de Oracle how to use the system tray

Answer 2

no puedo ver ningún problema con el público constructor TrayIcon(Image image, String tooltip, PopupMenu popup), nor is Java7 en WinXP/Win7 (Win2003/2008)

Answer 3

Para el actual TrayIcon implementación, no es posible agregar directamente un JPopupMenu o JMenu a TrayIcon. Sin embargo, algunas personas se las arreglaron para solucionarlo implementando un MouseListener personalizado que escucha el clic derecho solo en el Trayicon. Cuando haga clic con el botón derecho del mouse, establezca la ubicación del menú emergente en event.getXOnScreen() y event.getYOnScreen() y configúrelo.

Answer 4

Se trata de un problema conocido. Hay un bug report, que contiene el esquema de una solución. Lo he adaptado a continuación:

// Build your popup menu 
final JPopupMenu trayPopup = new JPopupMenu(); 
// I'm using actions, there are other ways of doing this. 
trayPopup.add(someFantaticAction); 

// Get your tray icon 
trayIcon = new TrayIcon(icon, "My awesome application"); 

trayIcon.addMouseListener(new MouseAdapter() { 

    @Override 
    public void mouseReleased(MouseEvent e) { 
     maybeShowPopup(e); 
    } 

    @Override 
    public void mousePressed(MouseEvent e) { 
     maybeShowPopup(e); 
    } 

    private void maybeShowPopup(MouseEvent e) { 
     if (e.isPopupTrigger()) { 
      trayPopup.setLocation(e.getX(), e.getY()); 
      trayPopup.setInvoker(trayPopup); 
      trayPopup.setVisible(true); 
     } 
    } 
});
