    Description

      We can''t use ABC ( https://docs.python.org/3/library/abc.html ) with pyside :

      from abc import ABC
from PySide2.QtCore import QObject

class Abstract(ABC):
    pass

class Concrete(Abstract, QObject):
    pass 

line 7, in <module>
TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

      there somethings about PyQt5 https://stackoverflow.com/questions/46837947/how-to-create-an-abstract-base-class-in-python-which-derived-from-qobject
      but PySide 2 doesn't have pyqtWrapperType
