如何从系统托盘打开和应用程序？

Question

如何通过关闭按钮在系统托盘中发送java应用程序并通过单击系统托盘图标恢复？。

我曾尝试关注隐藏，但现在我如何通过点击系统托盘将其取回？

 getFrmTaskList().setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);

怎么可能有人给我适当的建议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.");
    }
