Hi, I am trying to do some rapid application development using the Gtk2 module and glade. And I am having problems placing values in comboboxes.

I haven't been able to find documentation in regard to the use of perl and gtk, without converting the glade file into perl code. Any pointers to such would be appreciated. Well here is the perl code:

#!/usr/bin/perl
use strict;
use warnings;
use Glib;
use Gtk2 '-init';
use Gtk2::SimpleList;


# Connect to the glade file
my $builder = Gtk2::Builder->new ();
$builder->add_from_file ('example.glade');
$builder->connect_signals ();
 
# connect to the combobox
my $combo = $builder->get_object ('combobox1'); 
my @listing = qw/random stuff just to test /; 
my $text;
 
# This is supposed to append the @listing to the
# combobox
foreach $text (@listing) {
    $combo->append_text ($text);
}

$builder->get_object ('window1')->show_all;
Gtk2->main;

And the example.glade

<?xml version="1.0"?>
<interface>
  <requires lib="gtk+" version="2.16"/>
  <!-- interface-naming-policy project-wide -->
  <object class="GtkWindow" id="window1">
    <child>
      <object class="GtkComboBox" id="combobox1">
        <property name="visible">True</property>
      </object>
    </child>
  </object>
</interface>

When I execute I get this error:

Gtk-CRITICAL **: gtk_combo_box_append_text: assertion `GTK_IS_LIST_STORE (combo_box->priv->model)' failed at /home/abijr/progs/perl/gtk/hello line 22.

Thanks in advance.
