Hi, well i’m going to explain my problem.
RUBY
I’m a windows user, but i want to program on ruby 1.9, there wasn’t a
msi installer so i downloaded the binaries (Ruby 1.9.1-p129-i386 Binary)
and put it on “C:”, then i modified the path variable to the ruby/bin
directory; then i tried a “hello world” with scite, pressed f5 and it
works! 
(just like php).
GLADE/GTK
Then i donwloaded the msi installer for glade 3.6.7 and gtk+ both came
in one msi installer, no need to correct path variable i guess, then i
install it on “C:”, i want this versions because i’ve heard that
libglade is deprecated, now gtkbuilder rules, well, glade runs ok.
PROBLEM
i don’t know what is missing, because i tried some code from internet
calling a simple window and returns this error:
in `require’: no such file to load – Gtk (LoadError)
this is the code:
require ‘Gtk’
window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
button = Gtk::Button.new(“Hello World”)
window.set_title(“Hello Ruby”)
window.border_width(10)
Connect the button to a callback.
button.signal_connect(‘clicked’) { puts “Hello Ruby” }
Connect the signals ‘delete_event’ and ‘destroy’
window.signal_connect(‘delete_event’) {
puts “delete_event received”
false
}
window.signal_connect(‘destroy’) {
puts “destroy event received”
Gtk.main_quit
}
window.add button
window.show_all
Gtk.main
Please help, thank you
