如何子类化QRunnable来运行任何成员函数？

from PyQt5.QtCore import QRunnable, QObject, pyqtSlot, QThreadPool

class MyRunnable(QRunnable):
    def __init__(self, func, *args, **kwargs):
        super(MyRunnable, self).__init__()
        self.func = func
        self.args = args
        self.kwargs = kwargs
    
    def run(self):
        self.func(*self.args, **self.kwargs)

class MyClass(QObject):
    @pyqtSlot()
    def my_member_function(self):
        # 这是需要运行的成员函数
        print("Running my_member_function")

# 创建线程池
threadpool = QThreadPool()

# 创建MyClass的实例对象
obj = MyClass()

# 创建子类实例对象，并传入成员函数及参数
runnable = MyRunnable(obj.my_member_function)

# 添加任务到线程池
threadpool.start(runnable)
