If you want to emit a GDK event, you need to allow to accept the event
to the widget which the event is emitted.

Here is an example which Gtk::Window emits the key-press-event.

----
require 'gtk2'
Gtk.init
window = Gtk::Window.new
window.add_events(Gdk::Event::KEY_PRESS_MASK)
window.set_default_size(300,200)
window.signal_connect("key-press-event") do |w, e|
  p "key pressed : #{e.keyval}"
end
window.show_all
Gtk.main
