java怎样获取鼠标在屏幕的坐标

代码如下：

import java.awt.FlowLayout;

import javax.swing.JButton;

import javax.swing.JDialog;

import javax.swing.JFrame;

import javax.swing.JPanel;

import java.awt.Point;

import java.util.Timer;

import java.util.TimerTask;

import java.awt.Color;

public class MouseInfo extends JFrame {

private final JPanel contentPanel = new JPanel();

JLabel value_x = null;

JLabel value_y = null;

/**

* Launch the application.

public static void main(String[] args) {

try {

MouseInfo info_frame = new MouseInfo();

info_frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

info_frame.setVisible(true);

info_frame.setAlwaysOnTop(true);

Timer timer = new Timer();

timer.schedule(new TimerTask() {

@Override

public void run() {

Point point = java.awt.MouseInfo.getPointerInfo().getLocation();

// System.out.println("Location:x=" + point.x + ", y=" +

// point.y);

info_frame.value_x.setText("" + point.x);

info_frame.value_y.setText("" + point.y);

}

}, 100, 100);

} catch (Exception e) {

e.printStackTrace();

}

/**

* Create the dialog.

public MouseInfo() {

setTitle("\u9F20\u6807\u5750\u6807\u83B7\u53D6\u5668");

setBounds(100, 100, 217, 156);

getContentPane().setLayout(new BorderLayout());

contentPanel.setBorder(new EmptyBorder(5, 5, 5, 5));

getContentPane().add(contentPanel, BorderLayout.CENTER);

contentPanel.setLayout(null);

JLabel lblx = new JLabel("\u5750\u6807x:");

lblx.setFont(new Font("宋体", Font.PLAIN, 15));

lblx.setBounds(22, 27, 66, 31);

contentPanel.add(lblx);

JLabel lbly = new JLabel("\u5750\u6807y:");

lbly.setFont(new Font("宋体", Font.PLAIN, 15));

lbly.setBounds(22, 68, 66, 31);

contentPanel.add(lbly);

value_x = new JLabel("0");

value_x.setForeground(Color.BLUE);

value_x.setFont(new Font("宋体", Font.PLAIN, 20));

value_x.setBounds(82, 27, 66, 31);

contentPanel.add(value_x);

value_y = new JLabel("0");

value_y.setForeground(Color.BLUE);

value_y.setFont(new Font("宋体", Font.PLAIN, 20));

value_y.setBounds(82, 68, 66, 31);

contentPanel.add(value_y);

}

Q1: 用java编写程序，读取键盘输入的字符并将其显示到鼠标所指的位置。

import java.awt.Color;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.KeyEvent;

import java.awt.event.KeyListener;

import java.awt.event.MouseEvent;

import java.awt.event.MouseMotionListener;

import javax.swing.JFrame;

import javax.swing.JLabel;

import javax.swing.JPanel;

import javax.swing.event.ChangeEvent;

import javax.swing.event.ChangeListener;

public class Demo1 extends JFrame implements

MouseMotionListener,KeyListener,MouseListener {

private JPanel content;

private JPanel bottom;

private JLabel show;

static String keyCode="";

public Demo1(){

content=new JPanel();

content.setLayout(null);

show=new JLabel();

show.setForeground(Color.white);

bottom=new JPanel();

content.setBounds(0, 0, 800, 600);

content.setBackground(Color.black);

content.add(show);

content.setFocusable(true);

content.addKeyListener(this);

content.addMouseMotionListener(this);

content.addMouseListener(this);

setTitle

("读取键盘输入的字符并将其显示到鼠标所指的位置");

setSize(800, 600);

setLocationRelativeTo(getOwner());

add(content);

add(bottom);

setVisible(true);

setDefaultCloseOperation(EXIT_ON_CLOSE);

}

@Override

public void keyPressed(KeyEvent e) {

// TODO Auto-generated method stub

keyCode+=String.valueOf((char)e.getKeyCode());

}

@Override

public void keyReleased(KeyEvent e) {

// TODO Auto-generated method stub

}

@Override

// TODO Auto-generated method stub

}

public static void main(String[] args) {

new Demo1();

}

@Override

public void mouseDragged(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseMoved(MouseEvent e) {

// TODO Auto-generated method stub

if(keyCode!=""){

show.setText(keyCode);

show.setBounds(e.getX()+20, e.getY(), 800, 30);

}

@Override

public void mouseClicked(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseEntered(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseExited(MouseEvent e) {

// TODO Auto-generated method stub

keyCode="";

}

@Override

public void mousePressed(MouseEvent e) {

// TODO Auto-generated method stub

}

@Override

public void mouseReleased(MouseEvent e) {

// TODO Auto-generated method stub

}

Q2: Java编程,显示鼠标位置,按下鼠标时显示鼠标位置,释放鼠标时停止显示

可以监听鼠标，实现这个接口就行MouseAdapter

//创建侦听器对象(匿名内部类)

MouseAdapter mouse = new MouseAdapter() { //mouse : 鼠标

/** 鼠标移动事件 */

public void mouseMoved(MouseEvent e) {

}

/** 鼠标单击事件 */

public void mouseClicked(MouseEvent e) {

}

/** 鼠标移出事件 */

public void mouseExited(MouseEvent e) {

}

/** 鼠标移入事件 */

public void mouseEntered(MouseEvent e) {

｝

};

this.addMouseListener(mouse); //监听鼠标操作

this.addMouseMotionListener(mouse); //监听鼠标移动

Q3: Java获取窗口鼠标坐标以及键盘按键

Java中的鼠标和键盘事件

使用MouseListener借口处理鼠标事件

鼠标事件有种按下鼠标键释放鼠标键点击鼠标键鼠标进入和鼠标退出

鼠标事件类型是MouseEvent 主要方法有

getX() getY() 获取鼠标位置

getModifiers() 获取鼠标左键或者右键

getClickCount() 获取鼠标被点击的次数

getSource() 获取鼠标发生的事件源

事件源获得监视器的方法是addMouseListener() 移去监视器的方法是removeMouseListener()

处理事件源发生的时间的事件的接口是MouseListener 接口中有如下的方法

mousePressed(MouseEvent) 负责处理鼠标按下事件

mouseReleased(MouseEvent) 负责处理鼠标释放事件

mouseEntered(MouseEvent) 负责处理鼠标进入容器事件

mouseExited(MouseEvent) 负责处理鼠标离开事件

mouseClicked(MouseEvent) 负责处理点击事件

使用MouseMotionListener接口处理鼠标事件

事件源发生的鼠标事件有种拖动鼠标和鼠标移动

鼠标事件的类型是MouseEvent

事件源获得监视器的方法是addMouseMotionListener()

处理事件源发生的事件的接口是MouseMotionListener 接口中有如下的方法

mouseDragged() 负责处理鼠标拖动事件

mouseMoved() 负责处理鼠标移动事件

控制鼠标的指针形状

setCursor(Cursor getPreddfinedCursor(Cursor 鼠标形状定义)) 鼠标形状定义见（书 P ）

键盘事件

键盘事件源使用addKeyListener 方法获得监视器

键盘事件的接口是KeyListener 接口中有个方法

public void keyPressed(KeyEvent e) 按下键盘按键

public void keyReleased(KeyEvent e) 释放键盘按键

public void keyTypde(KeyEvent e) 按下又释放键盘按键

Q4: java编写程序，使得当按下鼠标时显示鼠标的位置

给你一个简单示例：

import java.awt.*;

import javax.swing.*;

import java.awt.event.*;

public class Test extends JFrame

{

public static void main(String[] args)

{

new Test().setVisible(true);

}

public Test()

{

setSize(300,300);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

addMouseListener(new MouseAdapter()

{

public void mouseClicked(MouseEvent e)

{

setTitle(e.getX()+","+e.getY());

}

});

}
