PyQt5 QCalendarWidget – Enabling/Disabling Auto Fill Background Property

In this article we will see how we enable or disable the auto fill property of the QCalendarWidget, this property will cause Qt to fill the background of the calendar before invoking the paint event. The color used is defined by the QPalette. By default this property is false.

This property should be handled with caution in conjunction with Qt Style Sheets. When a calendar has a style sheet with a valid background or a border-image, this property is automatically disabled.

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

Syntax : calendar.setAutoFillBackground(True)

Argument : It takes bool as argument



Return : It return None

Below is the implementation
