How to send non-trivial datatypes over UDP?
Sending a string over an UDP socket is trivial, once you have correctly initialized the socket.
QByteArray datagram; datagram.append("STRINGTOSEND"); udpSocket->writeDatagram(datagram, hostaddress, port);
But what about other datatypes? What I am searching for is some way to send any data.
For example I have a QPointF pos, which I have to send over UDP. How could I do that, I cannot just call datagram.append on pos.
Is there any clean built-in way to do that?
Thanks for any help :)
Note that you should still structure your data properly. You can't just go and send anything and everything and expect the other side to automagically decode it.
Thank you a lot! I got it working with QDataStream :)
You're welcome !
