[Interest] QML data models question

How do I access list model data properties without a delegate?

I'm using a SelectionDialog with model: audioList

If audioList is implemented as QStringList in C++, I can access the 
model data with audioList[selectedIndex].

However, when using QAbstractListModel, my intuition failed.   I would 
have thought that a syntax like audioList[selectedIndex].artist would 
work, but it does not.

I then figured I'd cheat by making a public slot in audioList

     QString artist(int atIndex)

I thought a call with audioList.artist(selectedIndex) would work, but no 
go there either.  Seems like the audioList model instance seems to be 
some kind of special ethereal entity that does not follow normal rules 
for QML objects.

Anyways, I got around it by using another rootContext property that 
knows about the model, but I wonder if I'm missing an obvious and clean 
way to do this.

Like, I know I can access the data in the delegate.   Is there a way to 
define a delegate just to access the instance properties, keeping the 
default look and feel, including touch/mouse interaction logic?
