It appears that most (all ?) of the remaining cases of GtkOptionMenu
use the same style:
-Connect a callback (with an associated "user data" pointer or value)
to each individual entry of a GtkOptionMenu;
-Upon the callback when a specific entry is selected, use the associated
value as needed.
I decided to generalize the work I did for firewall_dlg.c to create
ws_combo_box_new_text_and_pointer() and associated functions.
Essentially: The functions are a slight generalization of
gtk_combo_box_new_text() and associated.
They store a pointer along with the combo_box dropdown text in the
list_store associated with the combo_box.
When an entry is selected and a callback is invoked, a simple
ws_combo_box_get_active_pointer() gets the pointer associated with the
selected (active) entry.
With these functions I think it should be a fairy simple matter to
replace all the remaining usage of GtkOptionMenu.
I'll mark the remaining GtkOptionMenu cases as "in progress" on the Wiki
"Deprecated GTK and Glib Functions Replacement" page.
