Subject: [ruby-gtk2] problem changing menu in Gtk::OptionMenu

 Hi all. I need (again) help with ruby-gtk2.

 I have problems with this little code fragment:

---------------------------------------------
#!/usr/bin/ruby

require 'glib2'
require 'gtk2'

class BotonOpciones < Gtk::OptionMenu
	def initialize(valores=nil, inicial=nil)
		super()
		
		add_options(valores, inicial) if valores
	end

	def add_options(valores, inicial=nil)
		@valores = valores
		@valor = inicial || valores[0]

		# Remove last menu. Is this necesary?
		if @menu
			remove_menu
			@menu.destroy
		end

		@items = []
		@menu = Gtk::Menu.new
		grupo = nil
		@valores.each do |v|
			item = Gtk::RadioMenuItem.new(grupo, v)
			@items << item
			grupo = item.group
			@menu.append(item)
			item.signal_connect('activate') do
				@valor = v if @valor != v
			end
		end
		set_menu(@menu)
		put_value(inicial) if inicial
	end
  
	def put_value(valor)
		@valores.each_with_index do |val, i|
			if valor == val then
				@items[i].active = true
				history = i
				return
			end
		end
	end

	def get_value
		@valor
	end
end

Gtk::init

ventana = Gtk::Window.new
ventana.set_title("Problema con OptionMenu")
ventana.signal_connect('delete_event') {exit}


vbox = Gtk::VBox::new(true, 10)

boton1 = BotonOpciones.new(['hola', 'hello'], 'hola')
boton2 = BotonOpciones.new(['adi坦s', 'bye'], 'bye')

boton1.signal_connect('changed') do
	boton2.add_options(['otro', 'other'], 'otro')
end

vbox.pack_start(boton1, true, true, 0)
vbox.pack_start(boton2, true, true, 0)

ventana.add(vbox)

ventana.show_all

Gtk.main
-------------------------------------------

 When I select value of boton1, boton2 doesn't change menu, but
 instead I get an empty list.

 I don't know if I am doing something wrong or this is a bug.

 My system is a Debian Sid with libgtk2 packages from experimental
 (version 2.4) and ruby-gnome2 from CVS.

 Thanks.
