请问怎样可以做一个能发送表情的聊天程序呢,还有选择表情的框是Pane的话，那每个表情都是一个按钮吗？欢迎各位高手大侠帮帮忙

Question

请问怎样可以做一个能发送表情的聊天程序呢,还有选择表情的框是Pane的话，那每个表情都是一个按钮吗？还有就是怎样设置才能像QQ那样，输出特殊的字符，就直接能显示图片呢？接收的时候，要怎样判断是否是特殊字符，然后把字符变成图片呢
，发送端和接收端该怎样设置这些问题呢？
在下有一段只能发送文字的代码，改了用JTextPane之后不知道为什么不会自动换行，永远只能发一条，只能刷那一条信息：
请各位高手大侠具体的教一教我

class ThreadForwenzi extends Thread {
  public ThreadForwenzi() {
 
  // 构造函数，可以用来传递你所需的某些参数，比如窗体对象，然后将其保存至成员变量中
  }
  public void run() { 
  AttributeSet   attrSet1 = null;
  try{
byte buf[]=new byte[1024];
DatagramPacket packet=new DatagramPacket(buf,buf.length);
socket=new MulticastSocket(5555);
while(true){
socket.receive(packet);

textPane.setText(s);

}

}catch(Exception e){}

button_1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
 new ThreadForwenzi().start();
 sendata();
}  public void sendata(){
try{

String msg=textPane_1.getText();
if(msg.equals(""))
return;
textPane.setText("");

Answer 2

表情还是图片纯粹点吧，用按钮也可以，但是我觉得没必要，就是图要同样大小（没比较过，看实际使用经验吧）特殊字符显示就是置换，检测到要显示的text中包含特殊字符，就代之以对应的图片显示你那个不会换行是每次都 setText 当前消息了吧？setText不是追加。像你这种情况先找一个例子看会比较好一点

Answer 3

谢谢，高手大侠们的提示，我有一个问题想问问
关于接收端的显示文字的问题，
按dracularking这个高手大侠所说的，textPane.setText(s+"\n");
这句话是会覆盖掉之前的信息的，但是textPane没有accept那样方便的自动换行代码
那我应该怎样去改写，才能做到能每次一接受到新的信息就刷出一条新的信息来显示呢？

Answer 4

使用textArea显示信息，用append追加新信息

Answer 5

谢谢，可是我必须使用JTextPane来做，因为要显示出图片来

Answer 6

这里的显示新消息其实是连同旧消息一并显示，那就得把 旧消息+新消息 一起setText到textPane中你所提到的textPane.setText(s+"\n"); 其中的s是不是没包括你所要显示的旧消息呢？

Answer 7

如果你要把当前显示的消息仍旧全部显示的话，用getText()+新消息
如果是要显示一定条目的话，就要裁剪getText()所获得的string

Answer 8

textPane.setText(textPane.getText+s+"\n");
这样吗，可是我这样写的话，还是只能够发送一条信息，还是说我写错了，请各位高手大侠指教
