Re: [ruby-gnome2-devel-en] Ruby bindings for Keybinder 3.0 ?

[cedlemo <ce...@gm...>]

John, try this (it works for me, I hope it will works for you) :

require "glib2"
require "gobject-introspection"
require "gtk3"

module Keybinder
   class Loader < GObjectIntrospection::Loader
   end
   loader = Loader.new(self)
   loader.load("Keybinder")
end

win = Gtk::Window.new
win.signal_connect("destroy") { Gtk.main_quit }
win.show

Keybinder.init

Keybinder.bind('<Ctrl>p') do
  puts "ctrl + p"
end

Keybinder.bind('XF86AudioNext') do
  puts "keysoundnext"
end

Gtk.main


Two things here:

* Keybinder need to be initialized with (#init)
* the bind method only take one argument, the callback is transformed in 
ruby the block do ... end.
