Aggiunta JPopupMenu al TrayIcon

Question

voglio aggiungere JPopupMenu alla barra delle applicazioni come TrayIcon (cioèsystemTray.add(trayIcon)), ma non ho trovato un modo per fare il so.From docs il costruttore di TrayIcon assomiglia:

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

C'è un modo per farlo?

Answer 1

Si può guardare in tutorial di Oracle e l'esempio how to use the system tray

Answer 2

non riesco a vedere alcun problema con costruttore pubblico TrayIcon(Image image, String tooltip, PopupMenu popup), nor is Java7 su WinXP/Win7 (Win2003/2008)

Answer 3

Per la corrente TrayIcon implementazione, non è possibile aggiungere direttamente uno JPopupMenu o JMenu a TrayIcon. Tuttavia, alcune persone sono riuscite a risolverlo implementando un custom MouseListener che ascolta solo il clic con il pulsante destro del mouse su Trayicon. Quando si fa clic con il pulsante destro del mouse, impostare la posizione del Popupmenu su event.getXOnScreen() e event.getYOnScreen() e impostarlo su di esso.

Questo è un problema noto. C'è un bug report, che contiene lo schema di una soluzione alternativa. L'ho adattato qui sotto:

// 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); 
     } 
    } 
});
