How To Create An Abstract Base Class In Python Which Derived From QObject

I'm trying to create an abstract base class for an interface, but I need it to derive from QObject for signals and slots. My class definition looks like this: import abc from PyQt5

Solution 1:

Based on Multiple inheritance metaclass conflict

Try

import abc
from PyQt5.QtCore import QObject, pyqtWrapperType

class FinalMeta(pyqtWrapperType, abc.ABCMeta):
    pass

class interface_class(QObject, metaclass=FinalMeta):
    pass
