How to add a GtkUiManager menubar to a hildon window
Some time ago i found a very cool tip from this blog (http://blogs.igalia.com/svillar): a simple and easy function to convert from a gtkuimanager menubar to a gtkmenu. We need to do this because hildon_window_set_menu requires a GtkMenu. Let see the source:
static
GtkWidget *
menubar_to_menu (GtkUIManager *ui_manager) {                                                                                                            
GtkWidget
*main_menu;
GtkWidget *menubar;
GList *iter;

/*
Create new main menu */
main_menu = gtk_menu_new();

/*
Get the menubar from the UI manager */
menubar =
gtk_ui_manager_get_widget (ui_manager, "/MenuBar");

iter =
gtk_container_get_children (GTK_CONTAINER (menubar));
while (iter)
{
GtkWidget *menu;

menu = GTK_WIDGET (iter->data);
gtk_widget_reparent(menu,
main_menu);

iter = g_list_next (iter);
}
return
main_menu;
}                  
And you can use it this way:
ui = gtk_ui_manager_new ();
....
hildon_window_set_menu(HILDON_WINDOW(window), GTK_MENU(menubar_to_menu (ui)));
