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, OS X, Linux GTK, etc. Les applications ainsi créées conservent l'apparence native du système sur lequel elles sont exécutées.

WxRuby est publié sous la licence WxRuby2.

1. #!/usr/bin/env ruby

2. begin

3. require 'rubygems'

4. rescue LoadError

5. end

6. require 'wx'

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

9. class MinimalFrame < Wx::Frame

10. def initialize(title)

11. The main application frame has no parent (nil)

12. super(nil, :title => title, :size => [ 400, 300 ])

13. menu_bar = Wx::MenuBar.new

14. The "file" menu

15. menu_file = Wx::Menu.new

16. Using Wx::ID_EXIT standard id means the menu item will be given
17. the right label for the platform and language, and placed in the
18. correct platform-specific menu - eg on OS X, in the Application's menu

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

20. menu_bar.append(menu_file, "&File")

21. The "help" menu

22. menu_help = Wx::Menu.new

23. menu_help.append(Wx::ID_ABOUT, "&About...\tF1", "Show about dialog")

24. menu_bar.append(menu_help, "&Help")

25. Assign the menubar to this frame

26. self.menu_bar = menu_bar

27. Create a status bar at the bottom of the frame

28. create_status_bar(2)

29. self.status_text = "Welcome to wxRuby!"

30. Set it up to handle menu events using the relevant methods.

31. evt_menu Wx::ID_EXIT, :on_quit

32. evt_menu Wx::ID_ABOUT, :on_about

33. end

34. End the application; it should finish automatically when the last
35. window is closed.

36. def on_quit

37. close()

38. end

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

42. def on_about

43. Wx::about_box(:name => self.title,

44. :version => Wx::WXRUBY_VERSION,

45. :description => "This is the minimal sample",

46. :developers => ['The wxRuby Development Team'] )

47. end

48. end

49. Wx::App is the container class for any wxruby app. To start an
50. application, either define a subclass of Wx::App, create an instance,
51. and call its main_loop method, OR, simply call the Wx::App.run class
52. method, as shown here.

53. Wx::App.run do

54. self.app_name = 'Minimal'

55. frame = MinimalFrame.new("Minimal wxRuby App")

56. frame.show

57. end
