[Gonzalo Romano]

hi this is the first mail a send to this list, so I'll introduce my
self, I'm an Argentinian systems engineering student  from UTN
(national tecnological university) introduction done here's the thing:
I'm implementing a genetic algorithm in squeak  I've found an
implementation but a wanted to do it my self, I managed to make all
the code from the algorithm itself but i can't find the way to display
it properly, on a nice window, I have implemented printOn: in all my
classes so i'm able to print all my individuals and populations
what i need is to have graphics of how they evolve and put them on a
window i know how to create a window but I don't how to put things on
them, and I've browse the senders of addMorph: Frame: but I dont
understand them.
any help is good for me  thanks
