<![CDATA[Send files over network]]>Hello,
I want to create a chat for exchanging text and files too (photos, videos ...). Thus, each participant sends each participant text and files.
I do not know how to organize it.
I think setting up a peer to peer architecture. I found a tutorial ("here":http://qt-project.org/doc/qt-5/qtnetwork-network-chat-example.html) to send text by peer to peer. However, I do not find how to send files.

Does someone could help me achieve this?

Thank you all.

QUdpSocket and QTcpSocket both inherit from QAbstractSocket, which inherits from QIODevice.

You can use the same socket to send and receive text and binary data. It is your responsibility, however, to properly parse the data at the receiving end.

Also, please remember that UDP protocol is stateless and does not guarantee the order the packets come in. It also does not warn on transmission errors.

In addition, do QDataStream allow me to send files and text or do I create 2 different sockets?
If yes, I guess I just have to replace QString by QDataStream in the 'sendMessage' function, isn't it?
