Hi,
Apologies for potentially mis-using this thread. But I have been struggling
recently making exactly this leap from simple GUI examples to a more elaborate
MVVM concept. Mainly I have been struggling finding nice example python code
bases, that allow some understanding to the beginner, which I certainly still
am, but also show enough complexity to see the concept in action.
Any hints / links to github or similar highly welcome. If the list is not the
appropriate place, I am happy if you email me directly.
Cheers,
Andreas
