class Parent
  def foo
    puts "Parent::foo called"
  end
end

module TheModule 
  def self.boo
    foo
  end
end

class Child < Parent
  include TheModule
  def initialize
    super
  end

  def boo
    TheModule.boo
  end
end

Child.new.boo

# Two questions:
# 1)  Why do I need Child.boo?  Shouldn't function TheModule.boo be mixed in
#     to Child?
#
# 2)  Any way I can get TheModule.boo to call Parent.foo?
#
#
# What I'm really trying to do is something like this:

module MenuBarUtils
  def create_menu title
    # Creates a Gtk::Menu and then calls #append, a function that's in
    # Gtk::MenuBar.
  end
  def add_menu_item menu, title, &action
    # create menu item, attach it to menu, and bind &action to it
  end
end

class MyMenuBar < Gtk::MenuBar
  include MenuBarUtils
  def initialize
    super
    file_menu = create_menu "File"
    add_menu_item(file_menu, "Quit") { exit }
  end
end
