java代码鼠标监听代码,java监听鼠标位置

Java 程序实现鼠标点击 键盘等事件

这个用MouseListener里的mouseEntered(MouseEvent

e)方法。

鼠标进入区域就产生事件反应。

如果之前申明了点击事件可以在entered时间里呼叫clicked事件。

Q1: java为按钮添加的鼠标监听

你总要说说是什么问题吧。这么多一点点的看多不好找，有了错误，找起来方便点

Q2: Java 鼠标监听事件 mouseMoved(MouseEvent)

public class BtnText1 extends  JFrame implements MouseMotionListener

不需要实现MouseMotionListener接口，你已经用了addMouseMotionListener方法

MouseAdapter类已经是实现了MouseMotionListener接口的。

改成

public class BtnText1 extends  JFrame

可以运行成功

Q3: JAVA 该怎么添加鼠标事件的监听器

这样子写比较好

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

import javax.swing.event.*;

public class MyPicture extends JFrame

{

JFrame frame;

JButton a1,a2,a3;

JPanel panel;

int mouseX,mouseY,sh=10,ss=290;

String msg="坐标：";

String setX,setY;

public MyPicture() //程序界面

{

frame=new JFrame("图形学实验");

a1=new JButton("直线");

a2=new JButton("弧");

a3=new JButton("裁剪");

panel=new JPanel();

panel.add(a1);

panel.add(a2);

panel.add(a3);

frame.add(panel);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setSize(300,300);

frame.setVisible(true);

addMouseListener(new MouseMonitor());

}

public void paint(Graphics g) //显示鼠标坐标

{

g.drawString(msg,sh,ss);

}

class MouseMonitor implements MouseListener {

public void mouseEntered(MouseEvent me) //鼠标进入事件

{

mouseX=getX();

mouseY=getY();

setX=mouseX+"";

setY=mouseY+"";

msg=msg+setX+" "+setY;

repaint();

}

public void mousePressed(MouseEvent me){}

public void mouseReleased(MouseEvent me) {}

public void mouseExited(MouseEvent me) {}

public void mouseClicked(MouseEvent me){}

}

public static void main(String[] args)

{

MyPicture org=new MyPicture();

}

}

Q4: java中监听鼠标

你如果要监听某个控件的鼠标动作，可以调用这个控件的addMouseListener(new MouseAdapter()

{

public void mouseOver(MouseEvent e)

{

.....函数体

}

//或其他的要用的函数，可参看jdk文档

}

);

下面的程序参考下:

jTextPaneIPList.addMouseListener(new java.awt.event.MouseAdapter() {

public void mouseReleased(java.awt.event.MouseEvent e) {

if (e.isPopupTrigger()) {

targetPane = jTextPaneIPList;

getJMenuItemPaste().setEnabled(true);

showPopup(e);

}

}

public void mousePressed(java.awt.event.MouseEvent e) {

if (e.isPopupTrigger()) {

targetPane = jTextPaneIPList;

getJMenuItemPaste().setEnabled(true);

showPopup(e);

}

}

private void showPopup(java.awt.event.MouseEvent e) {

getJPopupMenuConsole().show(e.getComponent(), e.getX(),

e.getY());

}

});

Q5: java窗口监听

点击事件是 b.addActionListener(new ActionListener() {

你用错了侦听器,给你改了一下.

--------------------------------------------------------------------

import java.awt.Button;

import java.awt.Color;

import java.awt.FlowLayout;

import java.awt.Frame;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.MouseAdapter;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

public class MouseEvent {

private static Frame f;

private static Button b;

private static int index = 1;

public static void test() {

f = new Frame("鼠标事件监听窗口");

b = new Button("转到");

f.setBounds(300, 200, 500, 300);

f.setLayout(new FlowLayout());

b.setBackground(Color.white);

f.add(b);

f.setVisible(true);

}

// 添加监听器

public static void myEvent() {

// 添加窗口关闭监听

f.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent w) {

System.out.println("此窗口在3秒内关闭！");

try {

Thread t = new Thread();

t.sleep(3000);

} catch (Exception e) {

System.out.println("关闭窗口时错误！");

e.printStackTrace();

}

System.exit(0);

}

});

b.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent e) {

System.out.println("鼠标进入当前按键" + index++ + "次");

}

});

// 添加鼠标监听

b.addMouseListener(new MouseAdapter() {

int i = 1;

int j = 1;

// 重写鼠标进入按键方法

public void mouseEntered() {

System.out.println("鼠标进入当前按键" + i++ + "次");

}

// 重写鼠标点击按钮方法

public void mousePressed() {

System.out.println("鼠标点击当前按键" + j++ + "次");

}

});

}

public static void main(String args[]) {

test();

myEvent();

}

}
