you can build http://logand.com/mplisp.tar.gz with Gtk FFI as follows:
- comment out everything except the lines containing gtk in the src/mod.h
and src/mod.fn files
- change Makefile; remove unused stuff from "picoFiles = ...", CFLAGS,
Then you have picolisp with src/mod/gtk.ffi.c wrapper.
The src/mod/gtk.ffi.c file should be usable even with the full-blown
32 bit picolisp. I have not tried it, but you would need to:
- build a DLL or use the picolisp's gcc function (and figure out how
to pass "CFLAGS" and "LDFLAGS" to it?)
- change function names; otherwise cfun_gtk_window_new would become
gtk:cfun_gtk_window_new which is ugly
The file src/mod/gtk.ffi.c is just a generated FFI wrapper to existing
Gtk functions. I have not implemented callbacks yet as there need to
be some non-trivial code written to pass around user_data. You can
get the idea either from gtk-server or CLisp Gtk module:
;;; callback handling
;; this is complicated as each callback can have a different number
;; of arguments and it is the last that is most interesting (a
;; gpointer to some data we manage)

There is also another approach which might be a bit limited in some
ways but is much simpler: using gtk-server. Have a look at the
You need to install gtk-server and change the line
(setq *GtkServer (pack (sys 'HOME) "/sw/gtk-server-2.2.4/gtk-server"))
in gtk.l to your real path.
