region() that needs to be updated, and a
rect() that is the bounding rectangle of that region. Both are provided because many widgets cannot make much use of
region() , and
rect() can be much faster than
Painting is clipped to
region() during the processing of a paint event. This clipping is performed by Qt’s paint system and is independent of any clipping that may be applied to a
QPainter used to draw on the paint device.
As a result, the value returned by

QPainter will not reflect the clip region that is used by the paint system.
