[Qt-qml] Accessing a QAbstractItemModel in QML outside a view

[Jan Ekholm]

Hi,

The subject says it all, apart from the context. Accessing a QAIM in a view (such as
a ListView) is all nicely documented and works as expected. However, how can I access
the same exposed C++ model outside a view? In my case I want to show a list of data and 
next to the list have some Text/Image items with more information about the selected item 
in the view. Totally normal stuff. 

Getting the index of the selected row is easy, the view gives me that. Getting the model 
instance is also easy, it's in the root context. However, getting data out of the model seems
to be impossible. I've tried all kinds of ways to access the data but none works. However, if
I look here:

http://doc.trolltech.com/4.7/qdeclarativemodels.html#accessing-views-and-models-from-delegates

it's seems that delegates can even write data to a model. This gives a somewhat perverse
situation where you can inside delegates read and write to models but outside a delegate
you can't even read data. 

So, this can't possibly be the case and there's something my thick brain just does not grok? 
I mean, models are one of the few ways you can get real data into a QML document, and not
being able to actually access it makes it all feel somewhat silly. I can make extra methods
on my subclassed QAIM on the C++ side to get data, but the point is that I should not have
to do that, it ought to just work.

Someone please give me some RTFM resource.

Best regards,
    Jan Ekholm
