托盘图标，但不是

Image

类型的银槐厅

哦

SystemTray Tray//

系统托盘

Image

img=(new

ImageIcon("images/锋隐icon.png")).getImage()//

托盘图标，建

议使用较小的图片

public MyTray(){

final JFrame frame=new JFrame()

JPanel jp=new JPanel()

frame.add(jp)

frame.setSize(320,240)

frame.setLocationRelativeTo(null)

frame.setResizable(false)

frame.setIconImage(img)//

设置窗口左上角的图标

frame.setVisible(true)

Tray=SystemTray.getSystemTray()//

获得系统托盘实例

//

创建系统托盘的右键d出菜单

PopupMenu pm=new PopupMenu()

MenuItem mi0=new MenuItem("Open")

MenuItem mi1=new MenuItem("Close")

pm.add(mi0)

pm.add(mi1)

trayIcon=new TrayIcon(img,"",pm)//

创建托盘图标实例

trayIcon.setImageAutoSize(true)/明消/

图标自动适应托盘，也就是说它自动

改变大小

trayIcon.setToolTip(" ")//

设置提示语

//

添加系统托盘图标

frame.addWindowListener(new

WindowAdapter()

{//

当“关闭”窗口时，最

小化到系统托盘

public void windowClosing(WindowEvent e) {

try {

Tray.add(trayIcon)

} catch (AWTException exc) {

exc.printStackTrace()

}

}})

mi0.addActionListener(new ActionListener(){ //

右键d出菜单的事件

监听

public void actionPerformed(ActionEvent e) {

frame.setExtendedState(JFrame.NORMAL)

frame.setVisible(true)

Tray.remove(trayIcon)

}

})

mi1.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e) {

System.exit(0)

Tray.remove(trayIcon)//

退出程序，移出系统托盘处的图标
