我在程序中实测必须是16*16的图片才行
下面的这个程序简单地实现了把Java应用程序缩小到托盘的方法.
程序运行的jdk要是1.6才行,因为这是J2SDK1.6新加的一些类和方法.
import java.awt.*;
import java.io.*;
import javax.swing.*;
import java.awt.event.*;
import javax.imageio.ImageIO;
public class Test extends JFrame{
private TrayIcon trayIcon;//托盘图标
private SystemTray systemTray;//系统托盘
public Test()
{
super("系统托盘图标");
systemTray = SystemTray.getSystemTray();//获得系统托盘的实例
setSize(150,150);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
try {
trayIcon = new TrayIcon(ImageIO.read(new File("0.gif")));
systemTray.add(trayIcon);//设置托盘的图标,0.gif与该类文件同一目录
}
catch (IOException e1) {e1.printStackTrace();}
catch (AWTException e2) {e2.printStackTrace();}
this.addWindowListener(
new WindowAdapter(){
public void windowIconified(WindowEvent e){
dispose();//窗口最小化时dispose该窗口
}
});
trayIcon.addMouseListener(
new MouseAdapter(){
public void mouseClicked(MouseEvent e){
if(e.getClickCount() == 2)//双击托盘窗口再现
setExtendedState(Frame.NORMAL);
setVisible(true);
}
});
}
public static void main(String args[])
{
new Test();
}
}
