Widgets inherit the layout direction automatically from their parent unless 
they are windows, in which case the application's layout direction is used. 
Normally there is only one layout direction, which is the application's one. 
Only in rare cases I think it makes sense to specifically override it, which 
is why you _can_ set it per widget.

But for testing purposes I recommend starting your application with "-reverse" 
or by setting the layout direction manually on the application object.
