PyQt5 QCalendarWidget 插入QAction

在这篇文章中，我们将看到如何在QCalendarWidget中插入QAction。为了做到这一点，我们使用insertAction方法，这个方法将动作插入到日历的动作列表中，在给出的动作之前。如果before是None或者before对这个部件来说不是一个有效的动作，它就会添加这个动作。

为了做到这一点，我们将使用QCalendarWidget对象的insertAction方法。

语法 : calendar.insertAction(before, action)

参数： 它需要两个QAction对象作为参数，第一个是已经添加的QAction，第二个是将被插入到’before’QAction之前的QAction。

返回： 它返回无。

下面是实现方法
