swing-将程序推至系统托盘

swing-将程序推至系统托盘

1.关闭弹框系统不退出，而是隐藏到系统托盘

frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
frame.addWindowListener(new WindowAdapter() {
    
    
    @Override
    public void windowClosing(WindowEvent e) {
    
    
        toSysTray();
    }
});

2. 退至系统托盘

private static void toSysTray() {
    
    

    if (java.awt.SystemTray.isSupported()){
    
    
        System.out.println("support....");
    }

    frame.setVisible(false);

    ImageIcon trayImg = new ImageIcon("src/main/resources/static/jd.gif");//托盘图标

    PopupMenu pop = new PopupMenu();//增加托盘右击菜单


    MenuItem show = new MenuItem("show");
    show.addActionListener(new ActionListener() {
    
    
        @Override
        public void actionPerformed(ActionEvent e) {
    
    
            tray.remove(trayIcon);
            frame.setVisible(true);
            frame.setExtendedState(JFrame.NORMAL);
            frame.toFront();
        }
    });

    MenuItem exit = new MenuItem("exit");
    exit.addActionListener(new ActionListener() {
    
    
        @Override
        public void actionPerformed(ActionEvent e) {
    
    
            tray.remove(trayIcon);
            System.exit(0);
        }
    });

    pop.add(show);
    pop.add(exit);

    trayIcon = new TrayIcon(trayImg.getImage(), "jdsys", pop);
    trayIcon.setImageAutoSize(true);
    trayIcon.addMouseListener(new MouseAdapter() {
    
    
        @Override
        public void mouseClicked(MouseEvent e) {
    
    
            if (e.getClickCount() == 2){
    
    
                tray.remove(trayIcon); // 移去托盘图标
                frame.setVisible(true);
                frame.setExtendedState(JFrame.NORMAL); // 还原窗口
                frame.toFront();
            }
        }
    });

    try {
    
    
        tray.add(trayIcon);
    } catch (AWTException e) {
    
    
        e.printStackTrace();
    }

}
