PyQt5 Label – Accessing Vertical offset of shadow
  • Last Updated : 10 May, 2020

In this article we will see how we can access the vertical offset of shadow to the label, offset is basically distance between the shadow of the label and the label by default offset value is 8 although we can change it any time.

In order to do this we use yOffset method

Syntax : shadow.yOffset()
Here shadow is the QGraphicsDropShadowEffect object

Argument : It takes no argument

Return : It returns float value



Below is the implementation
