如何在pyqt中的类之间继承？

from PyQt5.QtWidgets import QMainWindow, QPushButton

# 创建父类
class BaseWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("Base Window")
        self.setGeometry(100, 100, 300, 200)

        self.button = QPushButton("Click me", self)
        self.button.clicked.connect(self.on_button_click)

    def on_button_click(self):
        print("Button clicked in Base Window")

# 创建子类
class ChildWindow(BaseWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("Child Window")

    def on_button_click(self):
        print("Button clicked in Child Window")

# 创建应用程序
app = QApplication([])
window = ChildWindow()
window.show()
app.exec_()
