在JTabel中怎么能让鼠标选中一行，立即就能在文本框里面显示出相应的信息
----------------解决方案--------------------------------------------------------
你对JLabel做个鼠标监听试试
----------------解决方案--------------------------------------------------------
你说的鼠标监听是不是指鼠标单击事件？

给你个鼠标监听的　　如果解决就和我说一声啊．．
//MyCanvas.java
import java.awt.*;
import java.awt.event.*;
import java.util.*;
public class MyCanvas
  implements KeyListener,MouseListener{
  //变量定义
  Canvas c;
  String s ="";
  TextField t;
  //主函数
  public static void main(String args[]){
      Frame f = new Frame("Canvas");
      MyCanvas mc = new MyCanvas();
      mc.c = new Canvas();
      mc.t = new TextField();
      f.add("South",mc.t);
      f.add("Center",mc.c);
      f.setSize(300,150);
      mc.c.addMouseListener(mc);
      mc.c.addKeyListener(mc);
      f.setVisible(true);
}
//响应键盘事件
public void keyTyped(KeyEvent ev){
    t.setText("keyTyped");
    s+=ev.getKeyChar();
    c.getGraphics().drawString(s,0,20);
}
//响应键盘按下
public void keyPressed(KeyEvent ev){ }
//响应键盘抬起
public void keyReleased(KeyEvent ev){
    t.setText("keyReleased");
}
//响应点击鼠标
public void mouseClicked(MouseEvent ev){
    t.setText("mouseClicked");
    c.requestFocus();
}
//响应压下鼠标
public void mousePressed(MouseEvent ev){
    t.setText("mousePressed");
}
//响应松开鼠标
public void mouseReleased(MouseEvent ev){
    t.setText("mouseReleased");
}
//响应鼠标进入
public void mouseEntered(MouseEvent ev){
    t.setText("mouseEntered");
}
//响应鼠标退出
public void mouseExited(MouseEvent ev){
    t.setText("mouseExited");
}
}
