It seems to me that there is nothing original in the ocaml binding of  
so most of the time you can search in the documentation of gtk in any  
other langage
and "quite easily" adapt it to ocaml. Maybe the only problem with  
lablgtk is that it uses
the object facilities of ocaml and that many people are not very  
aware of those features. But in that case
what we need is a better documentation of the object features of ocaml.

And I think it is not a good idea. We have to factor code and  
It is better to have one good documentation of gtk in one langage,  
that 10 bad documentation
of gtk in 10 langages.
Maybe one day when .net or a similar thing will take over the world  
we will have less problems.

Well, gtk is cross-platform.

And yet again reinvent the wheel. I am quite sure that you will  
reinvent just exactly gtk :)

Well you have already that with lablgtk.

I had a look to fruit in haskell, fudgets, fran, ... and other  
attempts to make gui in functionnal style, and most of the time
I found the code more complex that the classical  widget/callback   
with global variable or closure model.

You have that for gtk, ok it is not in ocaml but you can make the  
translation quite easily from langage X to ocaml.

Do you really find useful such RAD tools ?
