How to know "y" property of an Item when it is created in a ListView

[Fheanor]

I use a ListView and I need to fill my Window with the last Item that was inserted inside it.
In this case, I set the ListView property: contentY with the y value of myItem

My problem is that when you insert a new Item, I don't know how to know the y value of the Item because it is not yet set.

This is what I try:

ScrollView {
    id: scroll
    ListView {
        model: DelegateModel {
            id: visualModel
            model: myModel //Model is set in the cpp
            delegate: Rectangle {
                id: rectangleDelegate

                Component.onCompleted: {
                   rectangleDelegate.ListView.view.contentY = rectangleDelegate.y
                   console.log(rectangleDelegate.y ) //Not set yet (y = 0)
                }

                Button {
                    onClicked { 
                        rectangleDelegate.ListView.view.contentY = rectangleDelegate.y
                        console.log(rectangleDelegate.y ) //Now it is ok (y = rightValue)
                    }
                }
            }
        }
    }
}   

How could I proceed ?

Which item addRoot refers to?

Which item addRoot refers to?

I updated my code, it was a mistake

Thanks, now it's more clear.

Have you tried using positionViewAtIndex? Looks like just what might suit your needs.

@sierdzio This is exactly what I need, thanks !
