Hey Cedelmo, well I have something partially working with GI!

I know the library is hooked up because I have a call that works and it
outputs text that is in the library. However, this:

    Keybinder.bind('Menu', Callback, 'Key pressed')

fails with this error:


/usr/lib/ruby/gems/2.3.0/gems/gobject-introspection-3.1.1/lib/gobject-introspection/loader.rb:651:in
`validate_arguments': Keybinder.bind: wrong number of arguments (3 for
1) (ArgumentError)

I have looked at the source[1] and studied the annotation
documentation[2]. I can see that the actual bind function is skipped but
`keybinder_bind_full` is renamed to `keybinder_bind`. The header for
that function shows four parameters of which the last is optional, so my
call passing three parameters ought to be ok:

/**
 * keybinder_bind_full: (rename-to keybinder_bind)
 * @keystring: an accelerator description (gtk_accelerator_parse() format)
 * @handler:   (scope notified):        callback function
 * @user_data: (closure) (allow-none):  data to pass to @handler
 * @notify:    (allow-none):  called when @handler is unregistered
 *
 * Grab a key combination globally and register a callback to be called each
 * time the key combination is pressed.
 *
 * Since: 0.3.0
 *
 * Returns: %TRUE if the accelerator could be grabbed
 */
gboolean
keybinder_bind_full (const char *keystring,
                     KeybinderHandler handler,
                     void *user_data,
GDestroyNotify notify)

So I must have done something wrong, but I actually did very little.
Here's my GI module:

module Keybinder

  class Loader < GObjectIntrospection::Loader
  end

  loader = Loader.new(self)
  loader.load("Keybinder")
end

I'm not sure where to go from here...

Thanks for your help,
John
