Ruby

Interpreter: Ruby 1.8.5

window::mainloop()

Library: GTK+

require 'gtk2'

window = Gtk::Window.new.show
Gtk.main

Tcl

Loading the "Tk" package is all that is required to get an initial window:

  package require Tk

If you need an additional window:

  toplevel .top

If you are using the increasingly popular tclkit under MS Windows, all you have to do is associate the tcklkit with the extension ".tcl" and then create an empty file with the name (e.g.) nothing.tcl. Douple-clicking that will "open a window" (an empty one).

Toka

Library: SDL

Toka does not inherently know about graphical environments, but can interact with them using external libraries. This example makes use of the SDL library bindings included with Toka.
