I model the event produced when a hand drops a (grabbed) morph into
another morph.
I know the position of the drop, the dropped morph and the hand that
produced me.
See HandMorph>>dropMorph:event: for an example of usage.

I would add the following:

==========================

To handle this event a morph should override one of these methods:

#acceptDroppingMorph:event:

#justDroppedInto:event:

Additionaly, a morph can specify if it wants to accept a dropped morph by overriding #wantsDroppedMorph:event:. Symmetrically, the morph being dropped can specify if it wants to be dropped in another morph by overriding #wantsToBeDroppedInto:. 

Note that for a successful drop operation both parties need to agree.
