PyQt5 QCalendarWidget – Getting Background Role
  • Last Updated : 08 Jun, 2020

In this article we will see how we get the background role of the QCalendarWidget. Background role defines the brush from the calendar’s palette that is used to render the background. If no explicit background role is set, the calendar inherts its parent widget’s background role. In order to set the background role we use setBackgroundRole method.

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

Syntax : calendar.backgroundRole()

Argument : It takes no argument

Return : It return QPalette.ColorRole object but when printed its shows its associated value



Below is the implementation
