WxRuby

WxRuby est un toolkit graphique libre utilisant le langage de programmation Ruby. Il est basé sur le widget toolkit multiplate-forme wxWidgets, écrit en C++.

wxRuby permet d'utiliser Ruby pour la création d'applications graphiques sur Windows, Mac OS X, Linux GTK, etc. Les applications ainsi créées conservent l'apparence native du système sur lequel elles sont exécutées.

17.     # The "file" menu
    

18.     menu_file = Wx::Menu.new
    

19.     # Using Wx::ID_EXIT standard id means the menu item will be given
    

20.     # the right label for the platform and language, and placed in the
    

21.     # correct platform-specific menu - eg on OS X, in the Application's menu
    

22.     menu_file.append(Wx::ID_EXIT, "E&xit\tAlt-X", "Quit this program")

57. end
    

59. # Wx::App is the container class for any wxruby app. To start an
    

60. # application, either define a subclass of Wx::App, create an instance,
    

61. # and call its main_loop method, OR, simply call the Wx::App.run class
    

62. # method, as shown here.
