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

Hi all,

having just started to work with wxRuby, I would like to
- display a Wx::Notebook
- with several widgets in each row
- where the text field in the row horizontally fills the frame/window.
- and with a scrollbar in case the list gets too long to fit into
   the available space

Now I condensed the code I started with into this example (with faked 
data to fill the tabs):

---  code begin  ---

require 'wxruby'

class TabScroller < Wx::App

   def on_init
     frame = Wx::Frame.new( nil, -1, 'Matices in tabs' )
     frame.set_client_size( Wx::Size.new( 400, 120 ) )
     sizer = Wx::BoxSizer.new( Wx::VERTICAL )

     notebook = Wx::Notebook.new( frame, -1 )

     fill_tabbook( notebook )

     frame.show
   end

   def fill_tabbook( notebook )
     @sl = [ { :header => "Header 1",
           :list =>[ ["CB1", "Additional text1 "],
             ["CB2", "ding"],
             ["text2", "dong"] ]
         },
         { :header => "Third" ,
           :list => [ ["3rd check 1", "..." ],
           ["3rd check 2", "..." ],
           ["3rd check 3", "..." ],
           ["3rd check 4", "..." ] ]
         }
         ]

     @sl.each_with_index{ | line, idx  |
       panel = Wx::Panel.new( notebook, -1 )
       sizer = Wx::FlexGridSizer.new( 2, 0, 2 )
       panel.set_sizer sizer

       header = Wx::StaticText.new( panel, -1, line[:header] )
       sizer.add( header, 0, Wx::ALIGN_LEFT )
       sizer.add( Wx::StaticText.new( panel, -1, '' ), 0,
                  Wx::ALIGN_LEFT )

       line[:list].each { | item |
         checker = Wx::CheckBox.new( panel, -1, item[0] )
         sizer.add( checker, 0, Wx::ALIGN_LEFT )

         notes = Wx::TextCtrl.new( panel, -1, item[1] )
         sizer.add( notes, 1)

         sizer.add( Wx::StaticText.new( panel, -1, '' ), 0,
                    Wx::ALIGN_LEFT )
         sizer.add( Wx::StaticText.new( panel, -1, '' ), 0,
                    Wx::ALIGN_LEFT )
       }
       notebook.add_page( panel, "Tab No #{idx + 1}" )
     }
   end

end

if __FILE__ == $0
   TabScroller.new.main_loop()
end

---  code end  ---

These are my questions:
How would I introduce a Wx::ScrolledWindow (if that's what is needed) 
into this to add a scrollbar to each tab (so the user can use the scroll 
bar to reach all the widgets)?

How can I make the Wx::TextCrtl fill the available space to the right?

Any help would be greatly appreciated.

Happy rubying
