Here is the call graph for this function:

◆ draw()

void BlurEffect::draw ( QPainter * painter )

overridevirtual

This pure virtual function draws the effect and is called whenever the source needs to be drawn.

Reimplement this function in a QGraphicsEffect subclass to provide the effect's drawing implementation, using painter.

For example:

This function should not be called explicitly by the user, since it is meant for reimplementation purposes only.

Implements QGraphicsEffect.
