PyQt5 QCalendarWidget - Setting Action Event

Last Updated : 25 Nov, 2021

In this article we will see how we can implement the action event for the QCalendarWidget. This event handler is called with the given event whenever the calendar's actions are changed. This event handler can be reimplemented in a subclass to receive calendar actions events which are passed in the event parameter.
Below is the Calendar class code

# QCalendarWidget Class
class Calendar(QCalendarWidget):
    
    # constructor
    def __init__(self, parent=None):
        super(Calendar, self).__init__(parent)

    # overriding the actionEvent method
    def actionEvent(self, event):

        # printing the text
        print("Action Changed")

Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the actionEvent and inside the event print the text
3. Create a main window class
4. Create a Calendar object inside the main window
5. Set various properties to the calendar
6. Add actions and delete the action of calendar

Below is the implementation

Python3

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys

# QCalendarWidget Class
class Calendar(QCalendarWidget):

    # constructor
    def __init__(self, parent = None):
        super(Calendar, self).__init__(parent)

    # overriding the actionEvent method
    def actionEvent(self, event):

        # printing the text
        print("Action Changed")


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 650, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for components
    def UiComponents(self):

        # creating a QCalendarWidget object
        # as Calendar class inherits QCalendarWidget
        self.calendar = Calendar(self)

        # setting geometry to the calendar
        self.calendar.setGeometry(50, 10, 400, 250)

        # setting cursor
        self.calendar.setCursor(Qt.PointingHandCursor)

        # creating a QAction objects
        action1 = QAction("Geek", self)
        action2 = QAction("Python", self)

        # creating action list
        action_list = [action1, action2]

        # adding actions to calendar
        self.calendar.addActions(action_list)

        # removing action
        self.calendar.removeAction(action1)

        # 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())

Output :

Action Changed
Action Changed
Action Changed

"Action Changed" printed three times because two action are added and one action was deleted.
