Network Programming with Qt

[David Steuber]

I've just scanned through the Qt document 'network.html' and I'm a bit
confused. Can I use the Qt 2.1 library to implement UDP? Also, the
document had this ominous passage:

"The first set of classes (QSocket, QServerSocket, QDns, QFtp, etc.)
is not included in Qt but will be released as a seperate extension
after the Qt 2.1 release."

Is this extension available? What is it called? Do I need it to
implement a new tcp and udp protocols?

I need to be able to send and receive UDP datagrams. It would be
_extremely_ useful to do this within the Qt framework so that my
application can be ported to Windows. It also looks like the
signaling system used by Qt will allow me to avoid multi-threading.
Is this realistic, or should I still use background threads? If I can
avoid threads, I would like to.

Does anyone have any good pointers for using Qt for network
programming? The specific protocols I want to implement are H.323 and
H.324. This involves a TCP connection plus UDP datagrams. I've done
UDP in Java, now I would like to do it in C++ with Qt.

Thanks.

Ok, I found the QSocketNotifier class. At least that is something. I
would prefer to have QSocket, QServerSocket, et al available now
though. I like the idea of my code being portable to Windows, even
though I don't like Windows. It is a question of user base.
