      Description

      SETUP: 

      Create a simple GraphicsView with one top item only used to create

      children (to act as a layer which can be shown/hidden). Create one

      line as unique child.

       
      ISSUE: 

      When using a QGraphicsLineItem() as top, the view is displayed as

      expected, showing the line crossing the viewport. But when using a

      QGraphicsRectItem(), then the display shows more than just the line

      --> the 'itemsBoundingRect()' starts at (0,0) as top corner.

       

       

      Why this difference ?

      What is the recommended way to create an "empty" top level item ?
