Hi Thiago,
if you have a look at the little sample script I attached to my mail you'll
see that I'm actually constructing the application object within the
function that is executed in the other thread.
I do however import PyQt5 modules at the top of my script, and if I move
those imports into

Hi again,
It looks like the problem is that pyqt5 creates some hidden Qt objects very
early (i.e. upon importing some modules). If I move the imports as well as
the `MainWindow` definition into the secondary thread, everything appears
to be working fine.

I did indeed, but it seems its functionality isn't entirely suitable for my

Thanks all for the quick follow-up !
It's good to hear that what I have in mind *should* work. However, I'm
actually struggling a bit with the implementation. I have attached a very
simple test-case creating a simple (pyqt5) app. If I call the `main()`
function rather than `run_app()` directly,

Hi Stefan,
check out the excellent QThread API docs for the correct patterns for
interacting between UI and worker threads.
I don't think that it really matters which thread is your "main" thread. Surely
you have to call Q*Application::exec()
in one distinct thread and you definitely can have
Hello,
I'm working on some Python tests that interact with a Qt application. I
would like to run the application's event loop in a secondary thread, so
the primary thread can perform the test itself.
I read in the past that such a use-case wasn't supported by Qt, but I can't
find that
