QRunnables with QThreadPool seem to work great in my case.
I am instantitating my main worker class inside the QRunnable now to be
able send signals via that (e.g. runnable.worker.signal.emit()).
I tried multiple inheritance to just have one QRunnable class that can
emit signals, but that didn't

OK, thanks Thiago and Elvis.
I think I got the picture now and can proceed knowing I'm not heading
into a dead end.
Cheers,

Thanks Tim,
yes, that thought had crossed my mind while I was converting to
QRunnables. The latter seems to give me the control for what I need in
the main controller code without having to adjust the downloader class,
so I will see if that behaves through some testing.
But it's certainly goo
Thanks Elvis.
And my apologies (especially to Thiago) for posting a misleading and
incopmlete question.
I have been playing with converting to QRunner which seems to work fine
(haven't tested it thoroughly though).
I will have a look at QNetworkAccessManager so I can compare the
approaches, t

instead of re-architecting your threading model, could you just tweak the
downloader class to
take a list of files and then each one would be synchronous. multiple
concurrent downloads would each have a list of 1 file.
just a thought...

Hi Thiago,
thanks for your quick reply. I will try and give some more context:
I use the python requests module inside my PySide app to post requests
to a website. Some of those requests return a lot of data that I need to
parse to be able to show progress, other requests are file downloads

Hi,
I got another threading question for the pros out there:
In my current application I am using QThread objects and
QObject.moveToThread() to enable my GUI to download multiple files while
updating progress bars in the main event loop. This is the respective
snippet of code:
