Re: [ruby-gnome2-devel-en] can i make it full screen?

[Pen T. <rub...@an...>]

think for  Vincent Carmona,i get the code to get full screen
require 'gtk2'
class RubyApp < Gtk::Window
    def initialize
        super
        set_title "Center"
        signal_connect "destroy" do
            Gtk.main_quit
        end
     decorated=false
     move 0, 0
     gdk_screen=screen
    resize gdk_screen.width, gdk_screen.height
    show
    end
end
     window = RubyApp.new
Gtk.main

but ,why i can't use the code in the following codes?
require 'gtk2'
def callback(widget)
  puts "Hello again - #{widget.label}(#{widget}) was pressed."
end
window = Gtk::Window.new
window.title = "Hello Buttons"
window.border_width = 10
window.signal_connect('delete_event') do
  Gtk.main_quit
  false
end
box1 = Gtk::HBox.new(false, 0)
window.add(box1)
button1 = Gtk::Button.new("Button 1")
button1.signal_connect( "clicked" ) do |w|
  callback(w)
end
box1.pack_start(button1, true, true, 0)
button2 = Gtk::Button.new("Button 2")
button2.signal_connect("clicked") do |w|
  callback(w)
end
box1.pack_start(button2, true, true, 0)
window.decorated=false
window.move 0, 0
window.gdk_screen=screen
window.resize gdk_screen.width, gdk_screen.height
window.show_all
Gtk.main

the output is:

irb(main):026:0> window.gdk_screen=screen
NameError: undefined local variable or method `screen' for main:Object
  from (irb):26
  from :0
irb(main):027:0> window.resize gdk_screen.width, gdk_screen.height
NameError: undefined local variable or method `gdk_screen' for 
main:Object
  from (irb):27
  from :0


would you mind to tell me how to fix it?
