Well, there are several ways to do the same thing... A brief overview.

I'd avoid style sheets. They are slow, and full of nasty little 
suprises. It is easy to get started with, but hard to maintain in the 
long run.
Styles give you more control how stuff looks. They are harder to write, 
but easier to maintain in the long run. And using a proxy style, you can 
also tweak existing styles where needed, making the entry barrier lower.
Models can also suggest some formatting for items. Use sparingly. It 
really should not be the model's task to determine the presentation.
The actual rendering of items in the view is done by delegates. 
Delegates can completely determine how items look and what is displayed, 
but usually they defer to the style for that. They can be very powerfull 
to render non-standard items, modify data before it is rendered, etc. 
The QStyledItemDelegate is the standard delegate that takes things like 
style sheets into account.

So, you have multiple angles of attack here.
