When to use an items id versus the type?

[treaves]

I have a ListView whos id is myListView with a delegate. In the delegate code, I set the delegates color based on if it is the current item. Either of these two blocks in the delegate will accomplish this:

color: ListView.isCurrentItem ? "red" : "black"
// or
color:myListView.currentIndex === index ? "red" : "black"

However, this block does not:

color: myListView.isCurrentItem ? "red" : "black"

Related, I have a click-handler in my delegate to set the ListView's currentIndex property to the delegate's index. This block works:

myListView.currentIndex = index

whereas this one does not:

ListView.currentIndex = index

So when are you supposed to refer to something my it's id, and when by it's type? I find this inconsistency problematic.

The <Type>.<property> syntax is for attached properties.

Thank you very much for clearing that up for me.
