Where to find tutorial / lesson for networking in modern Qt?
-
I have the C++ GUI Programming with Qt4 book, and also been watching voidrealms Qt video series for learning Qt, however both of these cover older version of Qt which hasn't been much of a problem for the GUI stuff but the networking seems to have changed quite a bit. Both these sources are teaching QFtp and QHttp classes which appear to not exist anymore. Where can I find a tutorial / lessons on getting up to speed with QtNetworking, for noobs to the topic?

The networking has not changed in any substantial way since Qt4 introduced QNetworkAccessManager. QHttp and QFtp were deprecated in Qt4 and removed/hidden in Qt5. The book you refer to does, indeed, use the deprecated classes.
Start with the Networking Examples, particularly the HTTP example:
http://qt-project.org/doc/qt-5.0/qtnetwork/examples-network.htmland, of course, read them in conjunction with the documentation for the network classes:
