关于QTcpSocket的问题? [复制链接]

   我先用QtcpSocket连接到某个QServer端口,连接成功了,然后我想关闭这个连接再重连另一IP地址的QServer,但重连就连不上了,为什么?代码如下:
  //tcpSocket->disconnectFromHost();                            
tcpSocket->close();                                                                                           //在此之前已成功连接了
  serverIP->setAddress(ip);                                                                    //重设IP地址
tcpSocket->connectToHost (*serverIP, serverPort);        //连接server
tcpSocket->write(tcpDatas.toLatin1(),tcpDatas.length());                          //数据发送,没发送成功,为什么,请大家指教,先谢..
