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, the script fails: First I see
the error / warning message
`WARNING: QApplication was not created in the main() thread.`
the main window appears, but isn't fully constructed and it doesn't look
like the event loop is ever started. (The window's content isn't updated,
no button appears, and the app isn't receiving input events.)
What am I doing wrong ?
Thanks,
...ich hab' noch einen Koffer in Berlin...
