This is the abstract base class of graphicseffect, providing their functionality.

This class is a JS wrapper around Qt's QGraphicsEffect class

The QGraphicsEffect class is an abstract class and therefore, technically, no further instances actually have to be created. It is inherited by QGraphicsBlurEffect, QGraphicsColorizeEffect, QGraphicsDropShadowEffect, and QGraphicsOpacityEffect.
