For context:

  • Positional args: Func(1, 2)
  • Keyword args: Func(a=1, b=2)

pyqt5 works still if we use the keyword argument 'parent' for super calls to qt provided classes __init__ calls, but pyside6 throws an error (it generally seems a bit more strict about things).

You can inspect an __init__ call (ex: 'print(inspect.signature(QLabel.__init__))') to see if/what keyword arguments are accepted by it.

The __init__ calls changed in this patch don't accept a 'parent' keyword arg, just a positional arg for it.

Also use int casting to avoid type erros in datetime widget.
