[Cuis-dev] Is anyone working on Morphic-free Cuis?

[Luciano Notarfrancesco]

Hi Stephen,
I think Morphic will continue evolving in Cuis.

Morphs could be lightweight too, for example (thinking out loud) it might
make sense to have a superclass ProtoMorph for lightweight morphs with no
submorphs and no properties, etc. Not sure if at some point it will make
sense to make the dot in i a morph, but it’s not impossible. Many years ago
in Squeak I had morphs with thousands of submorphs and it worked fine, I
made a 3D earth with submorphs for airplanes, earthquakes, volcanos, etc,
with real-time data I retrieved from the web… I had to use quadtrees to
make it fast tho, but it was not hard.

Also, you don’t need to make every display object a morph, as Juan already
pointed out, just like TextMorph doesn’t add a morph per character or
stroke, and I’m guessing right now you don’t have a view for each music
event, right?

Anyway the main problem might be that you just don’t like Morphic, and
that’s fine too, it’s always nice to have alternatives and it would be
great if someone ported some MVC framework to Cuis.
