java程序系统托盘的托盘图标的显示

刚刚学习java,看到程序右下角图标的显示感觉很新鲜,于是上网查找一些资料。自己写了一个简单的程序实现了一下。

import java.awt.AWTException;
import java.awt.Image;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JFrame;


public class MySystemTray extends JFrame{

public MySystemTray() {
init();
}

public void init() {

this.setSize(300, 200);
this.setLocationRelativeTo(null);
this.setTray();
this.setVisible(true);
}

//添加托盘显示:1.先判断当前平台是否支持托盘显示
public void setTray() {

if(SystemTray.isSupported()){//判断当前平台是否支持托盘功能
//创建托盘实例
SystemTray tray = SystemTray.getSystemTray();
//创建托盘图标:1.显示图标Image 2.停留提示text 3.弹出菜单popupMenu 4.创建托盘图标实例
//1.创建Image图像
Image image = Toolkit.getDefaultToolkit().getImage("trayIconImage/clientIcon.jpg");
//2.停留提示text
String text = "MySystemTray";
//3.弹出菜单popupMenu
PopupMenu popMenu = new PopupMenu();
MenuItem itmOpen = new MenuItem("打开");
itmOpen.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
Show();
}
});
MenuItem itmHide = new MenuItem("隐藏");
itmHide.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
UnVisible();
}
});
MenuItem itmExit = new MenuItem("退出");
itmExit.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
Exit();
}
});
popMenu.add(itmOpen);
popMenu.add(itmHide);
popMenu.add(itmExit);

//创建托盘图标
TrayIcon trayIcon = new TrayIcon(image,text,popMenu);
//将托盘图标加到托盘上
try {
tray.add(trayIcon);
} catch (AWTException e1) {
e1.printStackTrace();
}
}
}

//内部类中不能直接调用外部类(this不能指向)
public void UnVisible() {
this.setVisible(false);
}
public void Show() {
this.setVisible(true);
}
public void Exit() {
System.exit(0);
}


public static void main(String[] args) {
new MySystemTray();
}
}
