QGraphicsView no refreshement

[evergreen]

Hi,
I'm currently working with a QGraphicsView and I encounter some problems either when I try to put a transparent object over it or try to apply a blur effect.
I 'm pretty sure that the reason is the same : the QGraphicsView always refreshes its display which messes with the transparency and the blur effect probably instantly desappear.

So, I would like to know if there's a way to temporary stop a QGraphicsView (or the QGraphicsScene in it) to refresh. To somehow freeze its display.

Thanks

Hello,
maybe this will help you
@QGraphicsView->setViewportUpdateMode(QGraphicsView::NoViewportUpdate)@
Update: or you can realise this func your self
@
void MyGraphicsView::freezePaint(bool freeze) { m_freezePaint = freeze; }

void MyGraphicsView::paintEvent ( QPaintEvent * event )
{
if (!m_freezePaint)
QGraphicsView::paintEvent(event);
}
@
something like this :-)
