Hi

I understand that the virtual list can handle a large number of model 
items but I am wondering about situations where you might have thousands 
or millions of items in a database.  I would think that you would not 
want to load your model with the entire database table but would want 
some way of loading fixed number of items at a time.

Is there some kind of mechanism to load a fixed number of items and as 
the user scroll done the list more data is requested from the database 
server?  I did not find any mention of this in the list documentation 
and wondered if this is something I have to build myself.

Secondly does the model dispose of items so that it eventually does not 
hold millions of items?  If so how is this controlled?

Thanks,
Simon
