PyQt5 QDateTimeEdit – 同时选择日期和时间文本

在这篇文章中，我们将看到如何选择QDateTimeEdit小组件的日期和时间文本。QDateTime基本上是QDate和QTime的组合，即它同时拥有日期和时间。而QDateTimeEdit小组件是用来显示或接收QDateTime的。选定的文本可以用来复制或删除。

为了做到这一点，我们将使用QDateTimeEdit对象的selectAll方法。

语法： datetimeedit.selectAll()

参数： 它不需要参数

返回： 它返回无

下面是实现

class Window(QMainWindow):
 
    def __init__(self):

        # setting date time to it
        datetimeedit.setDateTime(QDateTime(2020, 10, 10, 11, 30))
 
        # time

# create pyqt5 app

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