Subject: Re: wxRuby: How to add a scrollbar to a Wx::Notebook tab

The only thing that appears to be in the wxRuby arsenal to handle 
something Scrollable is Wx::ScrolledWindow, but whenever it is attempted 
to be implemented it complains that there is no on_draw method. I 
haven't done any digging to see if it's got any subclasses successfully 
implemented in wxRuby.

Kevin, Nick, any thoughts?
