I did some more research and it seems this is the way to do it:

// This code must be placed directly in the ListView WheelHandler { acceptedDevices: PointerDevice.Mouse property int speed: 2 property Flickable flickable: parent.parent onWheel: (event) => { let scroll_flick = event.angleDelta.y * speed; if(flickable.verticalOvershoot != 0.0 || (scroll_flick>0 && (flickable.verticalVelocity<=0)) || (scroll_flick<0 && (flickable.verticalVelocity>=0))) { flickable.flick(0, (scroll_flick - flickable.verticalVelocity)); return; } else { flickable.cancelFlick(); return; } } }

Hope this helps someone.

I got an answer that fixes the problem on Stackoverflow https://stackoverflow.com/a/75522782/5134351

Hello!

I think what is missing is a specification of the contentWidth and contentHeight of the ScrollView. The reason this breaks in the main case is because ColumnLayout has no default width/height. In spite of your specification of an implicitHeight and implicitWidth the ScrollView still must have the content sizes specified manually.

So adding:

contentWidth: parent.width contentHeight: the_column.height

to the ScrollView resolves the issues.

@fcarney Easy as that. This works perfectly fine with just a ListView. I added a ScrollBar to it and I have the same without any binding loops. Thanks!

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.
