QAbstractItemModel provides the method data() and the concept of "Role" that 
can help you to solve the problem. You can create a UserRole and returns a 
QVariant (e.g. item-hints of type whatever..). The Delegate can query the 
model and use the `hint' to draw the item.

the model provides the support for "fetching more data". It is need for things 
like the SQL model. Please Vladimir, take a look at
.. and friend
