PyQt5 QCalendarWidget – 使用完毕后关闭
在这篇文章中,我们将看到如何关闭QCalendarWidget。有时在使用完一个日历后,关闭它是必要的。它可以用一个关闭方法来完成,这个方法会将日历发送到QCloseEvent中。
为了做到这一点,我们将使用QCalendarWidget对象的close方法。
语法: calendar.close()
参数: 它不需要参数
返回: 它返回bool
下面是实现的过程

# creating a push button
button = QPushButton("Close", self)
# setting geometry tot he button
button.setGeometry(100, 280, 100, 40)
# adding action to the button
button.clicked.connect(self.do_action)
# method called by push button

# create pyqt5 app
