No, there is not, but I think the idea is very valid. I came up with it 
myself just two days ago ;-) (see topic "Alignment in QTableView"). I 
think it should be possible to apply a style to view items without 
having to resort to subclassing. Unfortunately, that is not possible 
yet, but perhaps it could be implemented in the form of a delegate. I'm 
doing some research into that.
