This is a feature request about explicit setter that do not break existing bindings. Suppose we have a currentIndex property binding between a SwipeView and a TabBar. As soon as we set the currenIndex manually, this binding will break, and we would have to repair it via:

    onMyEvent:  {
               swipeView.currentIndex = newIndex
               // repair the binding
               swipeView.currentIndex = Qt.binding(function() { return tabBar.currentIndex } )
           }
 

What about we generate a setter that updates the value without breaking the property binding, like this:

 swipeView.setCurrentIndex(newIndex)
