Thanks for this. I am (hopefully) going to make my own HandMorph
subclass this weekend. I will be very interested in any work that
is done with HandMorph.
I got the following advice from Dan Ingalls on working on something
like HandMorph without clobbering Morphic:
>What you might want to do instead would be to have a little do-it that
replaces the current >hand by yours, and saves the original in a global or a
class variable. Then you could add >a line to the error handler that would
restore the original hand and put yours where it can >be inspected -- maybe
just swap them.
>You might want to check out 'as:', a message in object that would allow you
to very quickly >initialize your hand as a copy of the existing hand.
> SaveHand := World swapHandWith: (World activeHand as:
CosmoHandMorph).
>Then in errors,
> CosmoHand := World swapHandWith: SaveHand.
Any other advice is very welcome.
