Tang, First of all question asked does not deserve the answer you gave. It was not offensive, the direct answer is not provided in documentation. And since in some cases scene ( for example if item with scene as a parent is deleted) is updated, somebody could expect that such happens even if child of such item is deleted.
> You must know the relation of QGraphicsScene, QGraphicsView and > QGraphicsItem. > > The QGraphicsView display the item of QGraphicsScene. I see no sense in your comment above. All it claims is that Earth is round. I would not say it if you tried to help, but all I see are attempts to piss off people. If you meant that my advice was incompetent and you suggest view update to be called you better follow your own advice on reading documentation. Scene can be attached to multiple views and calling update for the scene will schedule updates for all views. Even if it was incorrect, it is much better than you gave. Trust me I gave the best advice I could provide taking into account provided information. You indeed made an assumption that person asking the question was not trying to look in documentation - basically called a person asking a legit question an idiot.
