Hi Omer,

if you are implementing your network handling code in C++ anyway then 
threads
are very rarely needed as long as you implement it asynchonously. You 
should
never block the main thread, ever.

However when you decide you want to do that inside a thread, checkout 
the QRunnable[1] and
QThreadPool[2] classes. Using NetworkManger in another thread should be 
straightforward.

When you need to transfer something between threads use signals and 
slots as they
are threadsafe by default [3].
