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([‘adiós’, ‘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.
David
