Originally reported on Google Code with ID 904

With a tree layout, when dragging an element I needed to drag all the children at the
same time.  I knocked up a solution sufficient to my needs in about 40 minutes - see
attached changeset.   I might be a nice general feature to add to Roassal but its a
bit rough. It will likely need some critical love to polish it before integration.
 Later it might be made to work with ROSelection and multi-selected elements - but
that is out of my scope for the moment.

Hi Ben,

Thanks for your suggestion. I wrote a contribution inspired from your example.

Fixed in 1.457 of Roassal. Try this:

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| view elements |
view := ROView new.

0 to: 50 by: 10 do: [ :i | 
    elements := (ROBox green size: 10) elementsOn: (i to: i + 9).
    elements do: [ :e | e @ RODraggable @ ROPopup ].
    view addAll: elements.

    ROLine buildEdgesFromElement: elements first from: #yourself toAll: [ :v | (v + 1
to: v + 9) ].

    ROTreeLayout on: elements.

    (view elementFromModel: i) - ROBox + ROBox red.
    (view elementFromModel: i)
        @ ROAllConnectedNodeDraggable ;
        translateBy: i * 15 @ 10.
].

view open
