[Seaside] Re: [Pharo-users] Reactive Programming - anything like that in our realm?

[Guillermo Polito]

Well, a couple months ago I read this paper:

http://infoscience.epfl.ch/record/176887/files/DeprecatingObservers2012.pdf

I got inspired and Hacked up a morph that draws when you click on it, using
the following code:

Reactor loop: [ :reactor | | path |
path := PathShape vertices: { (reactor next: RMouseDown) position}.
self draw: path.
reactor loopUntil: RMouseUp with: [ | move |
move := reactor next: RMouseMove.
path addVertex: move position.
self draw: path.
].
self finishDrawing.
] on: self announcer.


p := RReactivePolygon new.
w := p openInWindow.
w extent: 400 at 400.

Of course it was just a dirty start, but if it is of use to anybody, here
is the code:
