PyQt5 QCalendarWidget – Removing memory reference
In this article, we will see how we can get delete the reference of the QCalendarWidget. Removing the last Python reference of the calendar object won’t be enough to fully clean up, because there could still be a reference held on the Qt side. In general, Qt tends not to implicitly delete objects. So there may be a need to take steps to delete them explicitly if memory usage is a concern.
In order to do this we will use deleteLater method with the QCalendarWidget object.
Syntax : calendar.deleteLater()
Argument : It takes no argument
Return : It returns None
Below is the implementation
