PyLint complains in virtual methods due to differ-arguments
I don't know the specifics, but here https://gitlab.gnome.org/GNOME/pygobject/blob/master/gi/pygi-type.c#L974 it's mentioned that the signature removes the implicit argument, however seems that confuses static checkers.
Not sure where the fault is at, just pointing in case this is fixable.
