dataChanged on a QML text element?

Question

I have a abstractListModel implemented that regularly calls dataCanged() to update a list. In the listmodel I have a variable that I want to display outside of the listview, but also want it to be updated when the listmodel is updated. Is there a way to emit dataChanged on elements displayed outside the listview?

Thanks, Kyle

QML properties have implicitely signals (onChanged) out of the box that can be used for such cases. See the examples here:
