my ruby–> ruby 1.8.5 (2006-08-25) [i486-linux]
recently i download “ruby-gtk2-0.16.0” and install it
in terminal…
mani@user-UBUNTU704:~$ vim welcome.rb
require “gtk2”
include Gtk
def quick_message(message)
# Create the dialog
dialog = Gtk::Dialog.new(“Message”,
$main_application_window,
Gtk::Dialog::DESTROY_WITH_PARENT,
[ Gtk::Stock::OK,
Gtk::Dialog::RESPONSE_NONE ])
# Ensure that the dialog box is destroyed when the user responds.
dialog.signal_connect(‘response’) { dialog.destroy }
# Add the message in a label, and show everything we’ve added to the
dialog.
dialog.vbox.add(Gtk::Label.new(message))
dialog.show_all
end
quick_message(“welcome”)
puts(“checking”)

thank you for help
Your code lacks a call to the method which starts the event loop, that
is
Gtk.main. Adding it to the end of your program should make it work.
You may not be aware of the fact that closing the dialog (either
clicking the
button or using the close button on the dialog’s frame) doesn’t quit
your
application, as it is now. To do so, you should connect the dialog
destroy
signal with the method Gtk.main_quit: in the method quick_message, add
the
code
dialog.signal_connect(‘destroy’){Gtk.main_quit}
at any point after the creation of the dialog and it should work.
