PyQt5 QCalendarWidget – Icon Changed Signal

In this article we will see how we can get the icon changed signal from the QCalendarWidget. Icon changed signal is emitted when the calendar’s icon has changed. Setting icon also emit the same signal.

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

Syntax : calendar.windowIconChanged.connect(lambda: print(“Icon Changed”))

Argument : It takes no argument

Action Performed : It will print the message whenever signal get emitted
