        # 主窗口

class MainWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("嵌入式绘图示例")
        # 计算中心坐标
        btn_width = 300
        btn_height = 300
        x = (self.width() - btn_width) // 2  # 水平居中
        y = self.height() * 0.75  # 垂直位置在75%处
        self.layout = QVBoxLayout()
        self.clock = AnalogClock(self)
        self.clock.setGeometry(x, y, btn_width, btn_height)
        self.clock.show()



if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()

    window.show()
    sys.exit(app.exec())

结果如下：
