PyQt5 QCalendarWidget – 插入 QAction

在本文中，我们将了解如何将 QAction 插入 QCalendarWidget。为了做到这一点，我们使用insertAction方法，该方法将动作插入到日历的动作列表中，在给定动作之前。如果 before 为 None 或 before 不是此小部件的有效操作，它会附加操作。

In order to do this we will use insertAction method with the QCalendarWidget object.

Syntax : calendar.insertAction(before, action)

Argument : It takes two QAction object as argument as argument, first is the QAction which is already added and second is the QAction which will be inserted before the ‘before’ QAction

Return : It return None

编程需要懂一点英语

下面是实现

Python3

        # creating a QAction objects
        action1 = QAction("Geek", self)

        # creating action list
        action_list = [action1, action2]
  
        # adding actions to calendar
        self.calendar.addActions(action_list)
  
        # 3 rd action
        action_mid = QAction("BTech", self)
  
        # inserting action in before second action
        self.calendar.insertAction(action2, action_mid)
  
        # creating label to show the properties
        self.label = QLabel(self)
  
        # setting geometry to the label
        self.label.setGeometry(100, 280, 300, 100)
  
        # making label multi line
        self.label.setWordWrap(True)
  
        # getting action of the calendar
        value = self.calendar.actions()
  
        # setting text to the label
        self.label.setText("Actions : " + str(value))
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
