MouseEvent类的对象应该实现这个接口。组件注册。使用addMouseListener（）方法，该对象可以被注册。

接口声明

以下是声明的java.awt.event.MouseListener接口：

public interface MouseListener
   extends EventListener

接口中的方法

S.N.	Method & Description
1	void mouseClicked(MouseEvent e)  Invoked when the mouse button has been clicked (pressed and released) on a component.
2	void mouseEntered(MouseEvent e)  Invoked when the mouse enters a component.
3	void mouseExited(MouseEvent e)  Invoked when the mouse exits a component.
4	void mousePressed(MouseEvent e)  Invoked when a mouse button has been pressed on a component.
5	void mouseReleased(MouseEvent e) Invoked when a mouse button has been released on a component.

继承的方法

这个接口继承的方法从下面的接口：

• java.awt.EventListener

MouseListener的示例

选择使用任何编辑器创建以下java程序D:/ > AWT > com > yiibai > gui >

AwtListenerDemo

package com.yiibai.gui;

import java.awt.*;
import java.awt.event.*;

public class AwtListenerDemo {
   private Frame mainFrame;
   private Label headerLabel;
   private Label statusLabel;
   private Panel controlPanel;

   public AwtListenerDemo(){
      prepareGUI();
   }

   public static void main(String[] args){
      AwtListenerDemo  awtListenerDemo = new AwtListenerDemo();  
      awtListenerDemo.showMouseListenerDemo();
   }

   private void prepareGUI(){
      mainFrame = new Frame("Java AWT Examples");
      mainFrame.setSize(400,400);
      mainFrame.setLayout(new GridLayout(3, 1));
      mainFrame.addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent windowEvent){
            System.exit(0);
         }        
      });    
   
      headerLabel = new Label();
      headerLabel.setAlignment(Label.CENTER);
      statusLabel = new Label();        
      statusLabel.setAlignment(Label.CENTER);
      statusLabel.setSize(350,100);

      controlPanel = new Panel();
      controlPanel.setLayout(new FlowLayout());

      mainFrame.add(headerLabel);
      mainFrame.add(controlPanel);
      mainFrame.add(statusLabel);
      mainFrame.setVisible(true);  
   }

   private void showMouseListenerDemo(){
      headerLabel.setText("Listener in action: MouseListener");      

      Panel panel = new Panel();      
      panel.setBackground(Color.magenta);
      panel.setLayout(new FlowLayout());        
      panel.addMouseListener(new CustomMouseListener());

      Label msglabel = new Label();
      msglabel.setAlignment(Label.CENTER);
      msglabel.setText("Welcome to TutorialsPoint AWT Tutorial.");

      msglabel.addMouseListener(new CustomMouseListener());
      panel.add(msglabel);

      controlPanel.add(panel);

      mainFrame.setVisible(true);  
   }

   class CustomMouseListener implements MouseListener{

      public void mouseClicked(MouseEvent e) {
         statusLabel.setText("Mouse Clicked: ("
         +e.getX()+", "+e.getY() +")");
      }   

      public void mousePressed(MouseEvent e) {
      }

      public void mouseReleased(MouseEvent e) {
      }

      public void mouseEntered(MouseEvent e) {
      }

      public void mouseExited(MouseEvent e) {
      }
   }
}

编译程序，使用命令提示符。到D:/ > AWT 然后键入以下命令。

D:AWT>javac comyiibaiguiAwtListenerDemo.java

如果没有错误出现，这意味着编译成功。使用下面的命令来运行程序。

D:AWT>java com.yiibai.gui.AwtListenerDemo

验证下面的输出
