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.

# A Wx::Frame is a self-contained, top-level Window that can contain
# controls, menubars, and statusbars

  def initialize(title)
    # The main application frame has no parent (nil)
    super(nil, :title => title, :size => [ 400, 300 ])

    menu_bar = Wx::MenuBar.new
    # The "file" menu
    menu_file = Wx::Menu.new
    # Using Wx::ID_EXIT standard id means the menu item will be given
    # the right label for the platform and language, and placed in the
    # correct platform-specific menu - eg on OS X, in the Application's menu
    menu_file.append(Wx::ID_EXIT, "E&xit\tAlt-X", "Quit this program")
    menu_bar.append(menu_file, "&File")

    # The "help" menu
    menu_help = Wx::Menu.new
    menu_help.append(Wx::ID_ABOUT, "&About...\tF1", "Show about dialog")
    menu_bar.append(menu_help, "&Help")

    # Assign the menubar to this frame
    self.menu_bar = menu_bar

    # Create a status bar at the bottom of the frame
    create_status_bar(2)
    self.status_text = "Welcome to wxRuby!"

    # Set it up to handle menu events using the relevant methods. 
    evt_menu Wx::ID_EXIT, :on_quit
    evt_menu Wx::ID_ABOUT, :on_about

  # End the application; it should finish automatically when the last
  # window is closed.
  def on_quit
    close()
  end

  # show an 'About' dialog - WxRuby's about_box function will show a
  # platform-native 'About' dialog, but you could also use an ordinary
  # Wx::MessageDialog here.
  def on_about

                   :version     => Wx::WXRUBY_VERSION,

# Wx::App is the container class for any wxruby app. To start an
# application, either define a subclass of Wx::App, create an instance,
# and call its main_loop method, OR, simply call the Wx::App.run class
# method, as shown here.
Wx::App.run do 
  self.app_name = 'Minimal'
  frame = MinimalFrame.new("Minimal wxRuby App")
  frame.show
