Try connecting the "button-press-event" signal on the button to a
function that calls gtk_menu_popup().

For that, connect to the "changed" signal on the option menu to reset
the selection (make sure not to cause an infinite loop!).


Both of these are demonstrated in my project "LogJam".  For the first,
look at popup_menu_cb() in
http://www.danga.com/lj/cvsweb.cgi/logjam/src/security.c?rev=1.2&content-type=text/x-cvsweb-markup

and for the latter, look at, er,
http://www.danga.com/lj/cvsweb.cgi/logjam/src/meta.c?rev=1.3&content-type=text/x-cvsweb-markup
but it's probably more complicated than its worth; you just call
       gtk_option_menu_set_history(GTK_OPTION_MENU(option_menu), 0);
in the function that responds to the signal.


Sorry if I have something technical wrong; I'm referring to GTK1.2 code
but GTK2.0 API docs. :)  I believe with the 1.2 option menu you
actually need to connect to the "activate" signal on each menu item.

I'll add that your latter suggestion may not be the best UI design, but
hey, I did the same thing... :)
