This program will print the current radiobutton's label if you press 'p'
inside the window:

#v+
#!/usr/bin/env ruby
require 'gtk'

window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
window.signal_connect('destroy') { Gtk.main_quit }
box = Gtk::VBox.new(false, 0); window.add box.show

group = nil
["gtk", "fox", "tk"].each do |name|
  button = Gtk::RadioButton.new(group, name) 
  group = button.group
  box.add button
  button.show
end

window.signal_connect('key_press_event') { |widget, key|
  if key.string == "p"
    group.each { |b| 
      b.each { |label| 
	puts label.get_text if b.active? 
      } 
    }
  end
}

window.show
Gtk.main
#v-

HTH,
Johannes
