请问:com.mkjdelove.www.ScribllePane1不是抽象的，未能覆盖java.awt.event.MouseLister中的抽象方法mouseClcked(java.awt.eve

原程序：

google_ad_width = 250; google_ad_height = 250; google_ad_format = "250x250_as"; google_color_url = "000000";

package com.mkjdelove.www;

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

import java.awt.event.MouseListener;

public class ScribblePane1 extends JPanel implements MouseListener,MouseMotionListener{

protected int last_x,last_y;

public ScribblePane1(){

this.addMouseListener(this);

this.addMouseMotionListener(this);

setPreferredSize(new Dimension(450,200));

}

public void mousePressed(MouseEvent e){

last_x=e.getX();

last_y=e.getY();

}

public void mouseDragged(MouseEvent e){

int x=e.getX();

int y=e.getY();

this.getGraphics().drawLine(last_x,last_y,x,y);

last_x=x;

last_y=y;

}

public void mouseReleased(MouseEvent e){}

public void mouseClick(MouseEvent e){}

public void mouseEntered(MouseEvent e){}

public void mouseExited(MouseEvent e){}

public void mouseMoved(MouseEvent e){}

}

第2楼. 由 zhuokai 于 2007-6-25 9:07:27 发表

把public void mouseClick(MouseEvent e){}改成public void mouseClicked(MouseEvent e){};

沒有實現接口MouseListener的mouseClick方法
