DEFINITION MODULE FOR "C" GtkBuilder ;

(*
   m2-GTK4 - GtkBuilder: build a widget tree from UI description XML
   (".ui" files).  Mapped onto <gtk/gtkbuild.h>.

   Two styles of API:

     * gtk_builder_new_from_file/_from_resource/_from_string are
       convenience constructors.  They return NIL on failure but do not
       report the error message.
     * gtk_builder_add_from_* take a VAR error: GError, so callers can
       inspect parse failures:

          VAR err: GError;
          err := NIL;
          IF gtk_builder_add_from_string(b, ui, -1, err) = 0 THEN ... END;
          IF err # NIL THEN GtkUtils.ErrorMessage(err, msg); ... END;

       The length argument is gssize; pass -1 for a NUL-terminated
       string.

   Objects are fetched by id with gtk_builder_get_object (an opaque
   handle - cast/assign to the concrete type).  GtkBuilder is a GObject:
   release it with GtkUtils.Unref / g_object_unref.

   The gtk_builder_value_from_string* functions are omitted because they
   need a GValue, which is not bound (yet).
