Can a morph currently being dragged by the hand receive a notification whenever
the hands moves?
I couldnt find any conceptual hook by looking at HandMorph or Morph. Also
senders of #isHandMorph dont reveal anything.
HandMorph>>position: aPoint
....
self privateFullMoveBy: ....
Morph>> privateFullMoveBy: delta
"Private! Relocate me and all of my subMorphs by recursion. Subclasses
that implement different coordinate systems may override this method."
My workaround is this add a hook on the following method, which recursively
gets sent whenever HandMorph>>position: is evaluated.
ADDED:
MyMorph>>privateFullMoveBy: delta
super privateFullMoveBy: delta.
owner isHandMorph ifTrue:[ self actOnHandMove ].
Anyone solved this problem before?
Thanks,
Fernando
