 Well, I know nothing to Gtk, but the events are defined as constant in the
module Gdk. If you want to test the key just test with the constant, for
example :

   e.keyval == Gdk::GDK_F1

 if you want a String you can perhaps make a reverse hash, something like
 this 

   keyname = {}
   Gdk.constants.each do |k| 
      if /^GDK_/ =~ k
         keyname[Gdk.const_get(k)] = k
      end      
   end
   p keyname[65470]

 Probably there is a better way to do it
