accessing selected item from OptionMenu

[Chris Phillips <chris thirtythreeandathird net>]

Hi, I've scoured the docs and must have missed somethign somewhere as I'm 
tryign to find a way to get the currently selected value of an OptionMenu 
but can't see any way. the option menu itself is derived from a button, so 
button->get_label would have worked i'd assume, but i can't find any way 
at all to get the current item. is this possible or do i need to rely on 
callbacks for each individual item?

thanks

Chris

p.s. from the gtk tutorial "Now that we've shown you the hard way, here's 
how you do it using the gtk_item_factory calls." I spent about 2 hours o 
my life trying to create an option menu with an item factory.... ack... 
the "hard" way is so so much easier to understand!
