Question

是不是 写侦听 鼠标动作的代码呀！ 或者根本就没有添加 鼠标侦听器！！ 你这样说的太含糊，最好是把代码贴出来！！

Answer 1

将5个Panel分别加入到5张卡片中?应该是将5个Panel放在一个面板中，而该面板是CardLayout布局
简单示例:
import java.awt.*;
import java.awt.event.*;
public class CardLayoutDemo
{
public static void main(String[] args)
{
new CardLayoutFrame().show();
}
}
class CardLayoutFrame extends Frame
{
CardLayout card;
Panel pMain;
Panel[] p;
Button btn;
public CardLayoutFrame()
{
btn=new Button("next");
btn.addActionListener(new BtnListener());
String[] s={"panel1","panel2","panel3","panel4","panel5"};
card=new CardLayout();
pMain =new Panel();
pMain.setLayout(card);
p=new Panel[5];
for(int i=0;i<5;i++)
{
p[i]=new Panel();
p[i].setBackground(new Color(i*30,i*40,i*50));
pMain.add(s[i],p[i]);
}
this.addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});
this.add(btn,BorderLayout.NORTH);
this.add(pMain);
this.setSize(300,300);
}
private class BtnListener implements ActionListener
{
public void actionPerformed(ActionEvent ae)
{
card.next(pMain);
}
}

}
