Subject: Re: ruby-gnome2 : problem with signal "insert-text"

The code :

#!/usr/bin/ruby1.8
require 'gtk2'
Gtk.init
window = Gtk::Window.new
window.signal_connect("destroy") {
         puts "destroy"
         Gtk.main_quit
}
textviewer = Gtk::TextView.new
window.add(textviewer)
window.set_default_size(600,400)
window.show_all
buffer = textviewer.buffer
buffer.create_tag("blue", {"foreground" => "blue"})
buffer.signal_connect_after('insert-text') do |a,first_char,text,length|
         if (text == '#')
                 first_char.offset -= 1
                 last_char = buffer.get_iter_at_offset(first_char.offset)
                 last_char.forward_to_line_end
                 buffer.apply_tag(buffer.tag_table.lookup("blue"), 
first_char, last_char)
                 update_window
         end
end

def update_window
                 while Gtk.events_pending? do
                         Gtk.main_iteration
                 end
end
Gtk.main
