PyQt5 QDateEdit – 递增日期

在这篇文章中，我们将看到如何增加QDateEdit的日期，即逐步更新。阶梯式更新意味着增加日期，它增加了当前选定的部分，即日、月或年。向上的箭头按钮执行同样的操作，尽管我们可以删除该按钮并制作我们自己的按钮。为了做到这一点，我们使用QDateEdit对象的stepUp方法。

语法： date.stepUp()

参数： 它不需要参数

返回： 它返回无。

下面是实现方法

# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
