Hi, this is not a very mature answer due to I am also not familiar with threads, but accessing a member is only possible by setting a pointer in the thread to the "main" class. But that's a bad idea, so leave it! But you can even use the signal and slot mechanism through the thread border. That should probably be the solution to your problem.

I'm having trouble with the translation.
What does thread-safe or reentrant mean?
In short words if possible

Thanks

Still about this subject... i've been reading about QtConcurrentRun.
Would it be possible for me to launch 2 member functions of the initial Ubmsr class in 2 different thread using this?
Imagine that f1() is broadcasting every 1 second and f2() is listening in other port!? This way i would have access to the GUI objects.

Does this make sense or showld i forget it?

In theory you could do that. But my personal opinion is that it's not worth the trouble. If you want to have multiple threads, then use a classical threaded approach and use signals and slots to communicate with the main thread that will manipulate the GUI. The real question is if you should use threads at all.
