Hello 2 all:
I want to write a chatting software using QT4.5, and it can handle chattings in the LAN.
I wonder what QT classes I have to read.

any idea appreciated!!
thanks!!

Do you know the "Network Chat Example" of Qt?

Thanks! I am reading the examples.
But it is uging UDP while I want to use TCP. What's more, I want the application allow some users to talk privately.

You said you want to write a software

It shouldn't be hard to change to tcp and insert a privacy function.

I think "private talk" has nothing to do with what protocal you use

most of chatting are using udp

uh, yeah, private talk has nothing to do with the protocal.
if I want to add a function that user can senf file to each other, which protocal do you suggest??
Thanks!!

Yes, as I know, if too many computers join the chatting, the Server UI would freeze. It is recomended that we use multithread at the server. But I have no knowledge of MultiThread.
Furthermore, I want the user can transfern files at the same time. Will TCP work fine with this??
Thanks!!
