这各程序，为什么我点窗口上的X的时候，怎么也关不掉，初学者，真是烦死了，望哪位高手可以帮忙解决！在就是载textfield 里面如何才能能让输入框是右对齐的啊，就是从右边开始输入！

Answer 1

你的程序写得乱七八糟，我很难改．给你个例子参考吧．import java.awt.*;
import java.awt.event.*;
//上面输入，回车，下面就显示
class TextXie extends Frame implements KeyListener{
TextField tf=new TextField();
TextArea ta=new TextArea(7,15);
TextXie()
{
this.setLayout(new BorderLayout());
this.setSize(200,300);

this.add(tf,BorderLayout.NORTH);
this.add(ta,BorderLayout.CENTER);
this.setVisible(true);
tf.addKeyListener(this);
this.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e)
{
System.exit(0);//这句是关闭窗口
}
});
}
public void keyPressed(KeyEvent e){
}

public void keyTyped(KeyEvent e){
if(e.getKeyChar()==e.VK_ENTER)
{
ta.setText(tf.getText());
}
}
public void keyReleased(KeyEvent e){
}
public static void main(String[] args)
{
new TextXie();
}
}

Answer 2

你前面那个程序继承是JFrame，关闭用setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 这个程序继承是Frame，所以不能用这个．

Answer 3

楼主啊，你忘记了添加窗口事件监视器了addWindowListener(this);

Answer 4

你的程序问题太多了，错误多的都数不清楚，还能通过编译，真是你的运气，但是它肯定不可能正常运行，实现你的目的的。我简单改了一下：~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~//package   jie;

Answer 5

前面程序的
public   void   windowClosing(WindowEvent   e)
{
//System.exit(0);
dispose();
        } 是我尝试修改的，忘记改回来了，应当是
public   void   windowClosing(WindowEvent   e)
{   System.exit(0);        }
