--- Comment #12 from Marcel Wiesweg <marcel.wiesweg at gmx.de> ---
IMO, which of the "modern" threading techniques you use is a matter of taste
and of your personal experience. I, for example, never use ThreadWeaver because
I've never used it and did not learn the API. Nor QtConcurrent btw. I'm a
friend of signal-based techniques; doesn't mean you have to use them.
You need to check if you need the possibility to cancel a threaded operation
(usually: yes) and provide progress info (usually: yes) and how this can be
done with your chosen API, here they can differ. In my experience,
multithreading the operations is not much of a problem, you'll need more work
to provide control over the multithreaded process.
