You're right, QVariant isn't necessary, only parenting. It's not very 
significant though as it only appears in the slot declaration.

BTW, I see in your code that the model's rowCount method is declared as a 
slot. What is the value in that? Does anything use this? I'm sure it's 
optional because it works without it, but is it generally helpful to declare 
it a slot anyway?
