[Interest] How to force scroll bars always visible on Mac

[Calogero Mauceri]

Hi all,

I have a tricky problem on Mac OS X 10.10 related to scrolling content 
on a QGraphicsView.

I have a QGraphicsView where I reimplemented the wheelEvent to zoom 
in/out the content of the view. The only way I have for scrolling the 
content is clicking and dragging the scroll bars. Actually on Mac OS X 
10.10 scroll bars are hidden by default and shown only when the user 
scrolls the area through mouse or trackpad. Having reimplemented the 
default behavior the scrollbars in my QGraphicsView are never shown.
Is there any Qt way to force the scroll bars to be always visible? Do 
you have any other suggestion on how to fix this problem?

Thanks,
     Calogero
