Hmm... mypy seems to be complaining. I removed the pytest-mypy extension, so you'll have to run it manually over your code to find the source of the error.

Yeah, had this on the mirror angle PR as well, for the exact same thing. It's related to the QWidget inheritance - it seems I need to do something like assert isinstance(widget_to_investigate, ConcreteWidget), and then can query attributes of the concrete widget type.

In terms of running mypy, I have it running as a pre-commit hook but perhaps it's ignoring the tests/ directory. Pretty sure I ran pre-commit run --all-files before pushing 🤷.

Looking good. Thanks for sorting this!

There's one line I think you can drop. but it's not esp important.
