Yes, that's how attached properties work in general. A quote from the detailed description of ListView: "ListView attaches a number of properties to the root item of the delegate, for example ListView:isCurrentItem. In the following example, the root delegate item can access this attached property directly as ListView.isCurrentItem, while the child contactInfo object must refer to this property as wrapper.ListView.isCurrentItem." > And I still think that ListView docs don't show all the signals the ListView > generates. Property change notifies are part of the QML language: http://qt-project.org/doc/qt-5/qtqml-syntax-signals.html#property-change-signal-handlers PS.
