There's something up at:

   address@hidden http://lilypond.org/~janneke/{arch}/2004-gnome

branched from address@hidden  libgnomecanvas and
libwnck compile and load.  It seems that I'm almost there...

I can't find how to translate

    gnome_canvas_item_new (gnome_canvas_root (canvas),
                                gnome_canvas_rect_get_type (),
                                "x1", (double) x1,
                                "y1", (double) y1,
                                "x2", (double) x2,
                                "y2", (double) y2,
                                "fill_color", "black",
                                "outline_color", "black",
                                "width_units", 1.0,
                                NULL);

probably into a call to

   (define-method set
     (of-object "GnomeCanvasItem")
     (c-name "gnome_canvas_item_set")
     (return-type "none")
     (parameters
       '("const-gchar*" "first_arg_name")
     )
     (varargs #t)
   )

the obvious:

   (line (make <gnome-canvas-line> #:x1 x1 #:y1 y1))

or
   (let ((line (make <gnome-canvas-line>)))
     (set line '("x1" x1 "y1" y1 "x2" x2 "y2" y2 "fill_color" "black" 
"width_units" 1.0))

or
    (set line 'x1 x1)

do not work.
