WebTo create a TCP connection in Qt, we will use QTcpSocket. First, we need to connect with connectToHost. So for example, to connect to a local tcp serveur: _socket.connectToHost (QHostAddress ("127.0.0.1"), 4242); Then, if we need to read datas from the server, we need to connect the signal readyRead with a slot. Like that: WebQTcpSocket buffers up all incoming data and emits readyRead () for every new block that arrives, and it is our job to ensure that we have received all the data we need before we start parsing. For this purpose we use a QDataStream read transaction. It keeps reading stream data into an internal buffer and rolls it back in case of an incomplete read.
