如何在python中创建从QObject派生的抽象基类

我试图为接口创建一个抽象基类，但我需要它从信号和插槽的QObject派生。我的类定义如下所示：

import abc
from PyQt5.QtCore import QObject

class interface_class(abc.ABC, QObject):
    pass

它失败于：

TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

有什么想法吗

谢谢

试一试

import abc
from PyQt5.QtCore import QObject, pyqtWrapperType

class FinalMeta(pyqtWrapperType, abc.ABCMeta):
    pass

class interface_class(QObject, metaclass=FinalMeta):
    pass
