Hello Russell,

I had to do something similar recently.  I used glade to build the
interface, but then had to go back and remove the GtkComboBoxEntry
widgest and replace them with GtkCombobox widgets.

Here's the code with a note:

Note #1:  localization_sites is a global.  The value is populated by the
user via a configuration file. (gchar **localization_sites;)


void build_wfo_list (GtkWidget *combobox)
{
        gint i=0;
        gint count=0;
        
        /* FILL IN THE DROP DOWN LIST */
        count = g_strv_length(localization_sites);
        for (i=0; i<count; i++) {
        gtk_combo_box_append_text(GTK_COMBO_BOX(combobox),
                                  localization_sites[i]);
        }
                
        /* SET A DEFAULT SELECTION */
        gtk_combo_box_set_active(GTK_COMBO_BOX(combobox), 0);
}
