- 12. Command Line #ruby puts 'What is your name?' name = gets process_name(name) puts 'What is your quest?' quest = gets process_quest(quest) 12
- 13. GUI require 'tk' root = TkRoot.new() name_label = TkLabel.new() {text "What is Your Name?"} name_label.pack name = TkEntry.new(root).pack name.bind("FocusOut") {process_name(name)} quest_label = TkLabel.new() {text "What is Your Quest?"} quest_label.pack quest = TkEntry.new(root).pack quest.bind("FocusOut") {process_quest(quest)} Tk.mainloop() 13
