How do I use the fullscreen in a gtkmm app?

["Garth's KidStuff" <garthskidstuff gmail com>]

Hi All,

   I notice that quite a few apps (firefox, gimp, terminal, etc. -- but not
   gedit, huh?) have the option to toggle fullscreen mode in their view menu
   using the F11 key.  How would I implement this in my Gtkmm app?

Thanks in advance
