[Glade-users] problem with gtk_builder_add_from_file

[roberthuff at rcn.com (Robert Huff)]

Hello:
        I've /just/ started using Glade (and GTK, for that matter) and
am missing clue here.
        Running Glade 3.4.5, xml file appended, the following code:

GtkTextBuffer *display_buffer,
     *display_buffer_position;
GtkTextIter   *iter = NULL;

GtkWidget *display_ptr;

extern int errno;

int main(argc,argv)
        int argc;
     char *argv[];
{
  gint i;

  GtkBuilder      *builder; 
  GtkWidget       *window;
  GladeXML        *xml;

  extern void clear_disp_buff();

  extern GtkTextIter *iter;

//  IMPORTANT - leave this before any Gtk/Glade calls

  gtk_init (&argc, &argv);

//
  puts("\nmain:: 0.0");
  builder = gtk_builder_new ();
  puts("\nmain:: 0.1");
  i = gtk_builder_add_from_file (builder, "ui.xml", NULL);
  if (!i)
    {
         puts("\nMain:: gtk_builder failed");
    }

  puts("\nmain:: 0.2");
  window = GTK_WIDGET (gtk_builder_get_object (builder, "root_window"));
  puts("\nmain:: 0");


        produces:


main:: 0.0

main:: 0.1

(ui:18101): GLib-GObject-CRITICAL **: g_value_type_compatible: assertion `G_TYPE_IS_VALUE (src_type)' failed

(ui:18101): Gtk-WARNING **: gtkliststore.c:608: Unable to convert from (null) to gchararray


(ui:18101): GLib-GObject-CRITICAL **: g_value_unset: assertion `G_IS_VALUE (value)' failed

main:: 0.2

main:: 0


        1) is there a debug tool/setting which will give a better idea
of what's going on?
        2) if not, what have I done wrong?  I adapted this code from
Miccah Carrick's (excellent but much too short) tutorial.  (Not
blaiming, just identifying.)

        Respectfully,


                                Robert Huff
