//添加文本域\下拉列表 p1.setLayout(new GridBagLayout());

  try {

  } catch(IOException e) {}   
  ta.append("Client host:"+socket.getInetAddress().getHostName()+"\n\n"); 
  try{
  in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
  out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
  out.println("Start");
  String str = in.readLine();
  System.out.println(str);
  ta.append(str);
     ta.append("\n");
  while(true){
try{
Thread.sleep(100);
} catch (InterruptedException e){};
str = in.readLine();
ta.append(str);
       ta.append("\n");
System.out.println(str);
if ( str.equals("Disconnect from Server") ){
break;
}
  }
   } catch(IOException e) {
   try {
   socket.close();
   } catch(IOException e2) {}
   } finally {
   try {
   socket.close();
   } catch(IOException e) {}
   }
   }
}
public class Client1 {
public static void main(String[] args)throws IOException, InterruptedException{
InetAddress addr = InetAddress.getByName(null);
new JabberClient1(addr);
}
}
无论用什么布局管理器都行(要求如下):
TextArea 放在左上角
JList 紧靠TextArea,放在右面
然后换一行在放:
JLabel .....TextField .....JButton
如果最大化,要使其控件自动合理的增长.
如果笔者用GridBagLayout最好,只需要修改界面段(谢谢)

Answer 1

JFrame f=new JFrame();
f.setResizable(false);
就可以了.

Answer 2

主要的代码如下，不过老兄你的类的结果太差了。对了我把你extends的JPanel去掉了。你看看界面可以吗，用GridBagLayout就是耐心点，别的没有什么。                list.setBorder(BorderFactory.createTitledBorder("我的好友?"));
//                contentPane.add(new JScrollPane(list),BorderLayout.EAST);//设置list的滚动条
                //添加文本域\下拉列表                p1.setLayout(new GridBagLayout());//                p1.add(ta);
//                p1.add(list);
                p1.add(ta, new GridBagConstraints(0, 0, 2, 1, 0.0, 0.0
                                                  ,GridBagConstraints.CENTER, GridBagConstraints.BOTH,
                                                  new Insets(10, 10, 10, 10), 0, 0));                p1.add(new JScrollPane(list), new GridBagConstraints(2, 0, 2, 1, 1.0, 1.0
                                                    ,GridBagConstraints.CENTER, GridBagConstraints.BOTH,
                                                    new Insets(10, 0, 10, 10), 0, 0));                p1.add(label, new GridBagConstraints(0, 1, 1, 1, 0.0, 0.0
                                                    ,GridBagConstraints.CENTER, GridBagConstraints.NONE,
                                                    new Insets(0, 10, 10, 10), 0, 0));
//
                p1.add(tf, new GridBagConstraints(1, 1, 1, 1, 1.0, 1.0
                                                    ,GridBagConstraints.CENTER, GridBagConstraints.HORIZONTAL,
                                                    new Insets(0, 0, 10, 10), 0, 0));
//
                p1.add(but1, new GridBagConstraints(2, 1, 1, 1, 0.0, 0.0
                                                      ,GridBagConstraints.CENTER, GridBagConstraints.HORIZONTAL,
                                                      new Insets(0, 0, 10, 10), 0, 0));
                contentPane.add(p1,BorderLayout.NORTH);
//                //挂标签\文本框\及按钮
//                p2.add(label);
//                p2.add(tf);
//                p2.add(but1);
//                contentPane.add(p2,BorderLayout.SOUTH);                f.setLocationRelativeTo(null);//
                f.setSize(500,200);
                f.show();
