GTK_OPTION_MENU(omenu)->menu_item is actualy selected menuitem of option
menu. I don't know any option how to get index of menuite, but you can set
to menuitem its index with gtk_object_set_user_data and then get it with
gtk_object_get_user_data.

for example :

create option menu :

index = 0;
mi = gtk_menu_item_new_with_label("0");
gtk_object_set_user_data(GTK_OBJECT(mi) , (gpointer)index);
index++;
[...]
mi = gtk_menu_item_new_with_label("1");
gtk_object_set_user_data(GTK_OBJECT(mi) , (gpointer)index);  
index++;
[...]
.....


get index of selected menuitem :

index = GTK_OPTION_MENU(omenu)->menu_item ?
gtk_object_get_user_data(GTK_OBJECT(GTK_OPTION_MENU(omenu)->menu_item)): -1;


Bye,
Stevo.
