[Q] moving morphs without the halo

What about the following?
| handle |
handle := HandleMorph new
forEachPointDo: [:point | | movementOffset |
movementOffset := (self globalPointToLocal:
point) - (self position).
self connectedShapes do: [:shape |
shape position: shape position +
self currentHand attachMorph: handle.
handle visible: false.
The method above I use to move all the connected morphs in a Jacarandá
diagram at the same time. It uses a HandleMorph and #position: so they
aren't grabbed (picked) by the hand.
Anyway. I see that Ned had already answered you and probably his
solution is better than mine. :)
