GtkMenuItem: How can I retrieve the label text?

[Todd Shadburn <tshadb ibm net>]

How can I retrieve the text from a GtkMenuItem?

I used gtk_menu_item_new_with_label() to create the menu items and then
attached the menu items
to a GtkOptionMenu. In my callback I get the currently selected menu
item from the option menu...
but I haven't been able to find a way to retrieve the label text.

Any help would be appreciated! :-)

Todd.
