如何将EditorWindow设置为屏幕中心？

from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtCore import Qt

class CenteredWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        # 计算屏幕分辨率
        screen = QApplication.desktop().screenGeometry()
        # 计算屏幕中心位置
        center_point = screen.center()
        # 设置窗口大小、位置使其居中
        self.setGeometry(int((screen.width() - self.width()) / 2),
                         int((screen.height() - self.height()) / 2),
                         self.width(), self.height())

if __name__ == '__main__':
    app = QApplication([])
    window = CenteredWindow()
    window.show()
    app.exec_()
