Not sure what you mean.
QGraphicsScene has not visual representation, and thus it cannot intersect with anything.
From the docs:

Note that QGraphicsScene has no visual appearance of its own; it only manages the items.
You can create a simple item to cover the all the size of the space you are interested in and make it the root parent of all the other objects in your scene.
