wxruby users - Mar 2009 - a newbie with some question

Hi, I''m new here

I''m planing to use wxruby to create a database program
with sqlite as backend
My system is Ubuntu 8.04, ruby 1.8.6 and wxruby-2.0.0
I choose to use xrc file as GUI definition
but somehow wxsugar didn''t work with my system
(xrcise is not a known command)

So I write ruby code to load the xrc file manually (thanks google) and it
works, with some problem though

so here is my question
1. Tab-navigation is not working (I pressed tab and the focus is not moving
to next widget). How do I get this working?

2. I cannot get a menu-item widget to work
> @menu = @finder.call("menuItem_quit")
>
does not work

Thanks

here is my code :
###

require ''rubygems''
require ''wx''

class Frame < Wx::Frame
    def initialize()
        super()
        xml = Wx::XmlResource.get
        xml.flags = 2
        xml.init_all_handlers
        xml.load("siswa.xrc")
        xml.load_frame_subclass(self, parent, "Siswa")

        @finder = lambda do | x |
            int_id = Wx::xrcid(x)
            begin
                Wx::Window.find_window_by_id(int_id, self) ||
int_idvt_button(button_save) { save() }
            rescue RuntimeError
                int_id
            end
        end

        @txtNis = @finder.call("textCtrl_nis")
        @txtNama = @finder.call("textCtrl_nama")

        button_quit = @finder.call("button_quit")

         evt_button(button_quit) { quit() }

    end

    def quit()
        self.close()
    end
end

Wx::App.run do
  a = Frame.new().show
end

and this is the xrc file
