How to make a Openbox dockapp with GTK?

I'm using Openbox and I want to make a dock-app (NOTE: not a dock like plank/docky but a dock-app like stalonetray or lal) in GTK+. How do I get the simple app I have written to sit in the dock area?

#!/usr/bin/env ruby
require "gtk3"
module Bang class Clock < Gtk::Window def initialize(clock_fmt) super(:toplevel) @label = Gtk::Label.new @fmt = clock_fmt self.add(@label) end def start(time) GLib::Timeout.add(time) do @label.markup = Time.now.strftime(@fmt) self.show_all end end end
end
if __FILE__ == $PROGRAM_NAME Gtk.init @clock = Bang::Clock.new('%T') @clock.signal_connect("destroy") do Gtk.main_quit end @clock.start(1000) @clock.show_all Gtk.main
end

I would strongly suspect that any tray applet worth its salt is following the Freedesktop system tray specifications so that every X11 application works on every desktop environment as expected.

GTK+ 3 certainly follows these specs. That should give you a rough idea of the bindings you'll be using. I've no idea how these are translated through Ruby though.
