Very kind.

Actually, I have a Rompecabezas (puzzle) app, from my first incursions in
Squeak.

Is more Pascal what Smalltalk / Squeak and solves the problem with a
PuzzleMorph subclass of PolygonMorph what roughly do some similar to your
suggestion.

And was in http://minnow.cc.gatech.edu/squeak/3938 for a long time now.

The made on it end in discovering the first bug on Squeak on 3.2 times, an
obscure case of when you do the fill some "pieces" don't could be grabbed .

What now I wish, as part of my students doing his first steps into Squeak
world, is give this awful code to one, and say what her should convert in a
semi - decent Squeak app.

And if is possible , use your beauty CurveMorph for doing.

I investigate about something like
| canvas |
    canvas _ FormCanvas extent: 40 at 32.
    canvas fillColor: (Color transparent).
    canvas drawPolygon: (Bezier3Segment example1) fillStyle: Color red
borderWidth: 2 borderColor: Color black.
    canvas form asMorph openInWorld

Or
| canvas c|
    canvas _ FormCanvas extent: 40 at 32.
    canvas fillColor: (Color transparent).
    c _ Bezier3Segment new from: 16 at 32 via: 20 at 22 and: 22 at 22 to: 24 at 32.
    c _  c asBezierShape.
    canvas drawPolygon: c asPointArray fillStyle: Color red borderWidth: 1
borderColor: Color black.!


The problem could be solved merging a PolygonMorph and a Curve Morph, as in
attached picture (made by hand and quick for you have the idea).

I let for the wiz figure how to get a closed figure with straight and curve
segments  :=)

Very thanks !!!

Edgar
