How to anchor QGraphicsWidget/Item (make them static) on QGraphicsView

I want to make something like a hud. I have a QGraphicsScene with a huge QPixmap, that I added to a much smaller QGraphicsView. Now I need to add some control elements, like QLabel, QPushButton and QGraphicsEllipseItem. That's, I think, is not a problem. I found this helpful page Graphics View Classes. But how do I anchor this control elements to the View or maybe better said how 开发者_StackOverflow社区do I not anchor them? When I drag the QPixmap, then I don't want that the hud is moving with the QPixmap out of the QGraphicsView. What do I need to do, to solve this problem. Hope someone can help me.

You should just have to create your widgets and specify the QGraphicsView in the constructor like this:

QPushButton *button1 = new QPushButton(view);
