最近需要一个java实现桌面弹窗的小功能，类似于电脑桌面右下角的小广告一样的功能，在csdn上找到一个很好的一个，功能很多，我去除了一点不需要的代码，改了下外观等。

修改后的代码如下：

InfoUtil.java

import java.awt.BorderLayout;

import java.awt.Color;

import java.awt.Cursor;

import java.awt.Desktop;

import java.awt.Dimension;

import java.awt.FlowLayout;

import java.awt.Font;

import java.awt.Point;

import java.awt.event.MouseAdapter;

import java.awt.event.MouseEvent;

import javax.swing.BorderFactory;

import javax.swing.JButton;

import javax.swing.JLabel;

import javax.swing.JPanel;

import javax.swing.JScrollPane;

import javax.swing.JTextArea;

import javax.swing.SwingConstants;

import java.awt.Insets;

import java.awt.Toolkit;

import javax.swing.JDialog;

/**

* @author Administrator 此工具类用法：实例化出对象，调用 void show("标题","内容") 方法. InfoUtil tool

* = new InfoUtil(); tool.show("标题","内容")

public class InfoUtil {

private TipWindow tw = null; // 提示框

private JPanel headPan = null;

private JPanel feaPan = null;

// 设置文本域自动换行

feature.setLineWrap(true);

jfeaPan.setPreferredSize(new Dimension(260, 100));

jfeaPan.setBorder(null);

jfeaPan.setBackground(Color.black);

tw.setBackground(Color.white);

// 为了隐藏文本域，加个空的JLabel将他挤到下面去

JLabel jsp = new JLabel();

jsp.setPreferredSize(new Dimension(300, 15));

public void handle() {

sure.addMouseListener(new MouseAdapter() {

}

public void show(String titleT, String word) {

this.titleT = titleT;

this.word = word;

// time = sdf.format(new Date());

init();

handle();

tw.setAlwaysOnTop(true);

tw.setUndecorated(true);

tw.setResizable(false);

tw.setVisible(true);

tw.run();

}

public void close() {

tw.close();

}

}

class TipWindow extends JDialog {

private static Dimension dim;

private int x, y;

private int width, height;

private static Insets screenInsets;

public TipWindow(int width, int height) {

this.width = width;

this.height = height;

dim = Toolkit.getDefaultToolkit().getScreenSize();

screenInsets = Toolkit.getDefaultToolkit().getScreenInsets(

this.getGraphicsConfiguration());

x = (int) (dim.getWidth() - width - 3);

y = (int) (dim.getHeight() - screenInsets.bottom - 3);

initComponents();

}

public void run() {

for (int i = 0; i <= height; i += 10) {

try {

this.setLocation(x, y - i);

Thread.sleep(50);

} catch (InterruptedException ex) {

}

}

// 此处代码用来实现让消息提示框6秒后自动消失

try {

Thread.sleep(6000);

}

main.java

public class main {

private final static String TITLE="弹窗";

public static void main(String[] args) {

InfoUtil test = new InfoUtil();

test.show(TITLE, "这是一个弹窗测试！");

}

}

效果如下：
