Java中窗口最小化到系统托盘

下面是代码

// 窗口最小化到任务栏托盘

public void miniTray() {

ImageIcon trayImg = new ImageIcon("image/biaoti.gif");// 托盘图标

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

MenuItem show = new MenuItem("还原");

show.setFont(font2);

MenuItem exit = new MenuItem("退出");

exit.setFont(font2);

show.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) { // 按下还原键

tray.remove(trayIcon);

frame.setVisible(true);

frame.setExtendedState(JFrame.NORMAL);

frame.toFront();

}

});

exit.addActionListener(new ActionListener() { // 按下退出键

public void actionPerformed(ActionEvent e) {

tray.remove(trayIcon);

System.exit(0);

}

});

pop.add(show);

pop.add(exit);

trayIcon = new TrayIcon(trayImg.getImage(), "网上图书借还管理系统", pop);

trayIcon.setImageAutoSize(true);

trayIcon.addMouseListener(new MouseAdapter() {

public void mouseClicked(MouseEvent e) { // 鼠标器双击事件

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 e1) {

// TODO Auto-generated catch block

e1.printStackTrace();

}

}

全局声明变量： static SystemTray tray = SystemTray.getSystemTray();

然后重写最小化监听

例如： public void show(int x, int y) {

frame.getContentPane().setFont(new Font("楷体", Font.PLAIN, 12));

frame.setTitle("管理员端");

frame.setBounds(x, y, 988, 640);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setVisible(true);

frame.setResizable(false);//设置不能改变大小，

frame.addWindowListener(new WindowAdapter() { // 窗口关闭事件

public void windowClosing(WindowEvent e) {

System.exit(0);

};

public void windowIconified(WindowEvent e) { // 窗口最小化事件

frame.setVisible(false);

miniTray();

}

});

}
