void QGraphicsScene::changed(const QList<QRectF> ®ion)
This signal is getting emitted and sometimes the list of the region is empty
what has been changed when the region is empty, do I need to consider this?
That's surprising indeed. What are you doing in your scene ?
Is there some pattern as to when you get an empty list ?
What are you doing in the slot connected to that signal ?
