如何在两个不同的类中同时使用mousePressEvent

from PyQt5.QtWidgets import QWidget, QApplication

class ClassA(QWidget):
    def mousePressEvent(self, event):
        # 处理ClassA中的鼠标按下事件
        print("ClassA: Mouse Pressed")

class ClassB(QWidget):
    def mousePressEvent(self, event):
        # 处理ClassB中的鼠标按下事件
        print("ClassB: Mouse Pressed")

if __name__ == '__main__':
    app = QApplication([])
    
    classA = ClassA()
    classB = ClassB()
    
    # 将ClassA和ClassB添加到窗口或布局中
    
    app.exec_()
