//并把它传给服务器incomingconnection()。
QAbstractSocket::SocketState _connect_stat = m_socket->state();
if (_connect_stat==QAbstractSocket::ConnectingState)
{
ui.status->setText(QString::fromLocal8Bit("成功"));
return 0;
}
else
{
ui.status->setText(QString::fromLocal8Bit("失败"));
return 0;
}
}
void Client::doSend()
{

m_socket->write(send.toStdString().c_str());

}
tcpserver.cpp中巢函数recvData()没有被调用，而readyread()已触发，不知道什么原因，请大牛指示一下
