In the constructor, we have connected the socket's readyRead() signal to a local slot. So, whenever the server sends a message through QTcpSocket::write(), we read the data and decode it:
m_receivedData.append(m_socket->readAll());
while(true) {
int endIndex = m_receivedData.indexOf(23);
if (endIndex < 0) {
break;
}
QString message = QString::fromUtf8(m_receivedData.left(endIndex));
m_receivedData.remove(0, endIndex + 1);
newMessage(message);
}
This code is very similar to the readyRead() slot of the server. It's even simpler because we only have one socket and one data buffer, so m_receivedData is a single QByteArray. The newMessage() implementation in the client is also much simpler than in the ...
