I'm trying to implement a selection marker so the user can see the
selected area in a QGraphicsView. The selection is drawed from a
mousePressEvent(..) until a mouseReleaseEvent(..). However the
QGraphicsItem isn't always cleared before the next selection? Is there
a flush() or something else I need to call?
I have attached the code. The following link points to an image
showing the selections not being cleared:
