Re: [gtk-list] Option menus in GTK+

[John Sullivan <sullivan eazel com>]

I suspect your best bet is just to keep track of the option menu's state in a
separate variable. You'll know the initial value of the option menu because
you set it up. Then whenever one of your option-menu-selection-triggered
functions gets called, you'll know the new state of the option menu because
(presumably) you know which state causes which function to be called. So you
have all the information you need to keep track of the option menu's settings.
