Thank you, it works!

@Quawetim I don't know which is better. For my comprehension, it is easier to use implicitHeight/implicitWidth of the item to be scrolled. For example, when the item is a ListView, implicitHeight is automatically updated when an element from the ListView is changed/added/removed. Your View item only have to set implicitHeight/implicitWidth and dynamically the ListView will adapt the scollbars limits/positions

Anybody ?

I am not finding the way to do this: to have ListView virtualization in all ListView usages. Someone is able to undertand why?

@jpnurmi Thanks !!! its working

If Qt 5.6 is an option: https://doc-snapshots.qt.io/qt5-5.6/qml-qt-labs-controls-scrollbar.html

I like it when you do QtQuick !

I figured out why the GridView wasn't scrolling. I'm still having issues with the transitions as I described, but I don't think that's really a reasonable question to ask here at this time...so that's why I deleted the post.

This thread is a bit old but.... An easier solution that worked for me is to use callLater to eliminate the problem. onCountChanged: { if (moveToEnd) { Qt.callLater( listview.positionViewAtEnd ) } }
