pyqt5 QMainWindow 居中

pyqt5 QMainWindow 居中：

def center(self,screenNum=0):
    '''多屏居中支持'''
    screen = QDesktopWidget().screenGeometry()
    size = self.geometry()
    #pyqt4中的方法
# screen = self.desktop.availableGeometry(screenNum)
#     size = self.geometry()
    self.normalGeometry2= QRect((screen.width()-size.width())/2+screen.left(),
                     (screen.height()-size.height())/2,
                     size.width(),size.height())
    self.setGeometry((screen.width()-size.width())/2+screen.left(),
                     (screen.height()-size.height())/2,
                     size.width(),size.height())
