Hi all,

I have created a basic frame and I’m trying to create a MenuBar inside  
it but although I have followed the API Documentation instructions I  
always get this error.

This is my code

require ‘wx’  
include Wx

class MyFrame \< Wx::Frame  
def initialize  
super(nil,-1,‘MinApp’)

```
@panel = Wx::Panel.new(self)
@menu_bar = Wx::MenuBar.new(
  2,
  ['File','Edit','Help'],
  ['Open','Save','Exit'],
  0)
show

```

end  
end

class MinApp \< App  
def on\_init  
frame = MyFrame.new  
end  
end

MinApp.new.main\_loop

And this is the error:

C:/Documentos/Ruby Scripts/Frame\_Ivo/lib/Ivo.rb:13:in `initialize': wrong # of arguments(4 for 0) (ArgumentError) from C:/Documentos/Ruby Scripts/Frame_Ivo/lib/Ivo.rb:13:in`new’  
from C:/Documentos/Ruby Scripts/Frame\_Ivo/lib/Ivo.rb:13:in  
`initialize' from C:/Documentos/Ruby Scripts/Frame_Ivo/lib/Ivo.rb:31:in`new’  
from C:/Documentos/Ruby Scripts/Frame\_Ivo/lib/Ivo.rb:31:in `on_init' from C:/Documentos/Ruby Scripts/Frame_Ivo/lib/Ivo.rb:35:in`main\_loop’  
from C:/Documentos/Ruby Scripts/Frame\_Ivo/lib/Ivo.rb:35:in `’

Thanks in advance for any help
