ok, this one seems to be solved.
in glade_module_register_widgets(), we do a

  glade_register_widget(simpledraw_get_type(), simpledraw_glade_new,
NULL, NULL);

with the following function:

// ---------------------------------------------------------
static GtkWidget *simpledraw_glade_new(GladeXML *xml, GType widget_type,
				     GladeWidgetInfo *info)
{
  SimpleDraw *sd = manage(new SimpleDraw);
  GtkWidget *w = GTK_WIDGET(sd->gobj());

  GObjectClass *oclass = G_OBJECT_GET_CLASS(w);

  for (int i=0; i<info->n_properties; i++) {
    const gchar *name = info->properties[i].name;
    const gchar *value = info->properties[i].value;
    GParamSpec *pspec;

    pspec = g_object_class_find_property (oclass, name);
    if (pspec) {
      GValue gvalue = { 0 };

      if (glade_xml_set_value_from_string(xml, pspec, value, &gvalue)) {
        g_object_set_property(G_OBJECT(w), name, &gvalue);
        g_value_unset(&gvalue);
      }
    }
  }

  return w;
}
// ---------------------------------------------------------

this could be written as a template to serve all the widgets in a glade
module.

it is not extensively tested so i would appreciate other users testing
it with their own widgets. (look at the previous post in thread for the
simpledraw example or write me if you can't get your widgets into glade3)

TIA!

however, glade still does not correctly apply property values when
loading a glade file. will do this next ;-)
