ADDITIONAL INFORMATION

It was my first try implementing the drag feature and was looking at the Gallery app to get started, but that code isn't properly working?

Since the feature is working in other places in the plasma desktop I finally used this as an starting point [1].

I assume the Gallery example code isn't up to date? Or is it an issue elsewhere?

Add Item element around the SwipeListItem

The ListItemDragHandle API requires the top-most component to have
a parent item between the listItem and the listView, otherwise it
does not work. This creates that.
