QPaintEvent ignore automatic clipping

Dariusz

Hey

I'm drawing an element which is animated. During the animation at some point the element may "leave" the bouding rect of widget geometry. How can I disable clipping in paintEvent so that it would draw outside the widget geo ?

Regards

My guess:

If you construct your own QPainter call the necessary (larger) setClipRect() and/or setCipRegion().
If you override QWidget::paintEvent(QPaintEvent *event) substitute your own QPaintEvent with (larger) QRect/QRegion before passing on.

Not sure whether you will have other problems (such as "artefacts" being shown) if you make a widget paint outside its boundingRect().

Hi,

Do you mean draw on a different widget ? If so, you can't. What you can do is use a larger widget so you have a larger surface to use.
