Extend QTcpServer to handle multiple clients

[DiamonDogX]

I have a class that extends QTcpServer and listens on a specified port for an incoming client connection (i.e. using nextPendingConnection() and so on). Was wondering what the most elegant way would be to handle multiple clients connecting and keeping track of them. This implies being able to identify each one, so maybe I'd have to do something like overload "incomingConnection( int socketDescriptor )"?

For each QTcpSocket returned by QTcpServer::nextPendingConnection() you can store information such as remoteAddress, remotePort and so on.

I assume you are referring to peerAddress() and peerPort()?

[mcosta]

Yes. you're right. I'm sorry for the mistake

So if multiple clients are connected and want to send data to the server, how should the server handle reading the data for each separate client (i.e. readyRead())?

[mcosta]

there isn't a unique solution but you could use a QSignalMapper to map each readReady signal with a slot with a parameter that allow to distinguish the client who sent data.

Read the documentation for use of QSignalMapper and try to use it.
