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
