How do I identify Drag & Drop sources across multiple QtQuick ListView controls.

JuanBucz

Hi:

I'm doing some prototyping use QtQuick ListViews.
I have 3 lists defined and am implementing Drag and Drop between those lists.
There are some "rules" I would like to implement.

Item from List1 can be dropped onto List 2 and List3
Item from List2 can be dropped onto List3, but not List1
When an item is an item is dropped onto List3, I would like to be identify the source and
update the associated ListModel
An Item from List can be dropped onto itself and the result should put the item into a different position with the list.
When an item is hovering over a destination, I would like to have a visual indicator differentiating between an allowable/disallowable destination..

Currently I have this small QML code snippet that handles 1 way Drag&Drop between 2 ListViews:

DropArea {
           id: dropArea1
           anchors.fill: parent
           onDropped: {
                var item = listView.model.get(listView.dragItemIndex);
                 listView1.model.insert(0, item)
                 listView.model.remove(listView.dragItemIndex);
                 listView.dragItemIndex = -1;
            }
}

I would like to be able to handle this functionality through QML.
Can someone help me with answers for these questions?

Thanks,
