java - 如何从系统托盘打开应用程序？

Question

如何通过关闭按钮发送系统托盘中的java应用程序并通过单击系统托盘图标恢复？

我尝试过隐藏，但现在如何通过单击系统托盘来取回它？

 getFrmTaskList().setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);

任何人都可以给我适当的建议吗？已经通过在搜索框中搜索尝试了所有其他方式

    This is example code you can create appropriate listener and make it working
    //Check the SystemTray is supported
    if (!SystemTray.isSupported()) {
        System.out.println("SystemTray is not supported");
        return;
    }
    final PopupMenu popup = new PopupMenu();
    final TrayIcon trayIcon =
            new TrayIcon(createImage("images/bulb.gif", "tray icon"));
    final SystemTray tray = SystemTray.getSystemTray();

    // Create a pop-up menu components
    MenuItem aboutItem = new MenuItem("About");
    CheckboxMenuItem cb1 = new CheckboxMenuItem("Set auto size");
    CheckboxMenuItem cb2 = new CheckboxMenuItem("Set tooltip");
    Menu displayMenu = new Menu("Display");
    MenuItem errorItem = new MenuItem("Error");
    MenuItem warningItem = new MenuItem("Warning");
    MenuItem infoItem = new MenuItem("Info");
    MenuItem noneItem = new MenuItem("None");
    MenuItem exitItem = new MenuItem("Exit");

    //Add components to pop-up menu
    popup.add(aboutItem);
    popup.addSeparator();
    popup.add(cb1);
    popup.add(cb2);
    popup.addSeparator();
    popup.add(displayMenu);
    displayMenu.add(errorItem);
    displayMenu.add(warningItem);
    displayMenu.add(infoItem);
    displayMenu.add(noneItem);
    popup.add(exitItem);

    trayIcon.setPopupMenu(popup);

    try {
        tray.add(trayIcon);
    } catch (AWTException e) {
        System.out.println("TrayIcon could not be added.");
    }
