Hi, in Glade's FAQ I found:

3.5 How do I get the value of a GtkOptionMenu?

Call gtk_menu_get_active() with the GtkOptionMenu's menu to get the currently
selected menu item. You can use g_list_index() to find its index in the menu:

void
on_button1_clicked                     (GtkButton       *button,
                                        gpointer         user_data)
{
  GtkWidget *option_menu, *menu, *active_item;
  gint active_index;

  option_menu = lookup_widget (GTK_WIDGET (button), "optionmenu1");
  menu = GTK_OPTION_MENU (option_menu)->menu;
  active_item = gtk_menu_get_active (GTK_MENU (menu));
  active_index = g_list_index (GTK_MENU_SHELL (menu)->children, active_item);

  g_print ("Active index: %i\n", active_index);
}
