将文本从一个帧文本区域发送到另一个帧文本区域 [英] sending text from one frame text area to another frame text area

问题描述

这是我将代码发送到另一个框架文本区域的功能，但只有一次我不能连续发送。

This is my function to send code to another frame text area but only once i can send not continuosly.

public void recmsg()
{
 try
 {
   String msg = dis.readUTF();
   String oldText = txt_recMsgClient.getText();
   StringBuilder yourStringBuilder = new StringBuilder();
   yourStringBuilder.append("\n").append(oldText).append(msg); 
   txt_recMsgClient.setText(yourStringBuilder.toString());
 }
 catch (IOException ex)
 {
   Logger.getLogger(ClientForm.class.getName()).log(Level.SEVERE, null, ex);
 }
}

推荐答案

public void recmsg()
{
 try
 {
   String msg = dis.readUTF();
   String oldText = txt_recMsgClient.getText();
   StringBuilder yourStringBuilder = new StringBuilder();
   yourStringBuilder.append("\n").append(oldText).append(msg);
   txt_recMsgClient.setText(yourStringBuilder.toString());

   // Update txt_recMsgClient
   txt_recMsgClient.repaint();
 }
 catch (IOException ex)
 {
   Logger.getLogger(ClientForm.class.getName()).log(Level.SEVERE, null, ex);
 }
}
