PyQt5 QCalendarWidget – Setting Close Event

In this article we will see how we can implement the close event for the QCalendarWidget. This event handler is called with the given event when Qt receives a window close request for a calendar from the window system. By default, the event is accepted and the calendar is closed. We can reimplement this function to change the way the widget responds to window close requests.

Below is the Calendar class code

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

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

        # setting text to the label
        print("Close Event Called")

Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the closeEvent 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. Close the calendar
