java - 将 JPopupMenu 添加到 TrayIcon

Question

我想将 JPopupMenu 作为 TrayIcon 添加到任务栏(即 systemTray.add(trayIcon)) 但我还没有找到这样做的方法。来自 docs TrayIcon 的构造函数如下所示:

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

有什么办法可以做到这一点吗？

这是一个已知问题。有一个 bug report ，其中包含解决方法的概述。我在下面进行了调整:

// 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);
        }
    }
});
