This is not completly true.
In fact only the file that contains the interface is fully autogenerated.
A separate file contains the callbacks' bodies and this file is only
In particular, one handler looks like that in the code :
let on_liste_des_messages_selection_changed selection text1 () =
let selection = selection () in
(* BEGIN on_liste_des_messages_selection_changed *)
prerr_endline "Event selection_changed";()
(* END on_liste_des_messages_selection_changed *)
and only the parts between BEGIN and END comments should be edited. Each
time you change your interface,
what you wrote between these comments is automatically reinserted is the
new code as body for the same handler.
Everything outside these comments is automatically generated.
This is pretty like what is done in C by glade.
If you want I can send you a complete example.

This is right but involves a lot of work to write the wrappers' generator.

My parser is based on the tony XML parser and not complete as I add widget
properties by need.
But if you already have some kind of complete abstract syntax for glade
I can write the parser for you.
