QWidget::update() and QRectF, QPainterPath

Message 1 in thread

I have a bunch of rectangular items that use QRectF for floating-point
accuracy, I am having trouble getting the correct QRect or QRegion to
pass to QWidget::update() to ensure that only the area they cover are
updated. I am painting with antialiasing disabled.

From another angle, what if I can generate a QPainterPath of what I
want to paint and I just want to call update with the area of the path
as a parameter?

thanks
