First, you know the index. The entries are simply
sequentially numbered from 0, so if you constructed them
you also know the index.

Then, there's sometimes the possbility you don't have the
original map from/to indices available any more. You can
obtain the list of items:

    GtkWidget *menu = gtk_option_menu_get_menu(GTK_OPTION_MENU(option_menu));
    GList     *list = GTK_MENU_SHELL(menu)->children;

and scan the list. It's usually a better idea to identifiy
the items explicitely with some g_object_set_[q]data(...) at
the time of construction and checking these instead of the
labels.
