After turning IntEnum into Enum, a few classes need more attention because the simple int coercion is no more sufficient. Instead, a bit of help is necessary to make the usage of the __or__ operator consistent, again. On first sight, this coercion to KeyCombination looks slightly unpythonic. But this originates in the complex matters. If you observe what types are actually added, this is very correct. Using the IntEnum version instead is not better. It is just hiding the ongoings by using int, which would also allow to combine two characters as a bad side effect. [ChangeLog][PySide6] PyEnum now handles QKeyCombination correctly with "|" or (deprecated) "+" operators, without falling back to using IntEnum.
