Hinzufügen JPopupMenu zum TrayIcon

Question

Ich möchte JPopupMenu in die Taskleiste hinzuzufügen, als TrayIcon (dhsystemTray.add(trayIcon)), aber ich habe nicht einen Weg zu tun so.From die docs der Konstruktor von TrayIcon sieht aus wie gefunden:

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

Gibt es eine Möglichkeit, das kann ich tun?

Answer 1

Sie in Oracle Tutorial schauen und Beispiel how to use the system tray

Answer 2

ich keine Probleme mit Konstruktor public TrayIcon(Image image, String tooltip, PopupMenu popup), nor is Java7 auf WinXp/Win7 (Win2003/2008)

Answer 3

Für die aktuelle TrayIcon sehen Implementierung, ist es nicht möglich, direkt JPopupMenu oder JMenu zu TrayIcon hinzuzufügen. Einige Leute haben es jedoch geschafft, das Problem zu umgehen, indem sie eine benutzerdefinierte MouseListener implementieren, die nur mit der rechten Maustaste auf die Trayicon hört. Wenn die Maus mit der rechten Maustaste geklickt wird, legen Sie den Speicherort des Popup-Menüs unter event.getXOnScreen() und event.getYOnScreen() fest und setzen Sie es auf visible.

Answer 4

Dies ist ein bekanntes Problem. Es gibt eine bug report, die den Umriss einer Problemumgehung enthält. Ich habe das unten angepasst:

// 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); 
     } 
    } 
});
