wxruby users - Jul 2012 - Adding Menu Bar and Menu on Window

I referred to wxRuby documentation to add Menu Bar and Menu on a Window,
but the code is not working.

I tried:

========== [CODE] ==========class MinimalApp < App
    def on_init
        @frame = MDIParentFrame.new(nil,-1,''RubyPIM - [Main
Window]'',Point.new(100,100),Size.new(1200,800)).show()
        @menubar = MenuBar.new

        @file = Menu.new
        @open = @file.append("Open", "open")
        @menubar.append(@file, "File")
        @frame.set_menu_bar(@menubar)
    end
 end
============================
I am getting error:

D:/Aptana Projects/RubyPIM/MainWindow.rb:13:in `on_init'': undefined
method `set_menu_bar'' for true:TrueClass (NoMethodError)
  from D:/Aptana Projects/RubyPIM/MainWindow.rb:18:in `main_loop''
  from D:/Aptana Projects/RubyPIM/MainWindow.rb:18:in `<main>''

If you?re just starting out with wxRuby, why do you use MDI windows?
These are quite complex windows, and for the beginning you?re far
better off using ordinary frames.

In your above code, @frame is set to `true'', which is the return value
of show. true doesn?t have a method #set_menu_bar, hence the exception.

As said, for a minimal app you don?t want MDI windows. Try something
like this:

===============================================require "wx"

class MinimalApp < Wx::App
  include Wx

  def on_init
    @frame = Frame.new(nil, title: "Main window")

    @menubar = MenuBar.new
    menu     = Menu.new
    @menubar.append(menu, "File")
    @frame.menu_bar = @menubar

    @frame.show
  end

end

MinimalApp.new.main_loop
===============================================
Oh, and please read this one:
http://wxruby.rubyforge.org/doc/wxruby_intro.html

You don?t have to obey the C++-derived method documentation directly.
wxRuby adds some nice and more rubyish wrappers around them.

Vale,
Marvin

I am new to Ruby and wxRuby as well. I started writing a real 
application which will make learning interesting. I therefore need an 
MDIWindow.
