Thanks for the generous welcome.  I'm usually a unix person, and web  
based, but got roped into working on an Access project. (Hence why I'd  
rather do this in ruby)

GUI stuff by hand is quite new to me. :)

I see that event firing, but it appears global, firing for everything  
that loses focus.  I've tried to identify what object was responsible  
via #get_event_object, #get_id, and  #id, but no luck so far.  How do  
I associate it with the combo box?

require 'rubygems'

require "wx"
include Wx

class HelloWorld < App
    def on_init
      helloframe = Frame.new(nil, -1, "Hello World")

      button = Button.new(helloframe, :label => 'Close', :pos =>  
[200,200])
      evt_button(button) {exit}
      cbo = ComboBox.new(helloframe,
                         :pos =>Point.new(10,10),
                         :choices => ["foo","bar"],
                         :value => "asdasd",
                         :style => CB_SORT)
      helloframe.show()
      evt_set_focus() {|w|
        # how do I tie this to cbo ?
        }
    end
  end
  HelloWorld.new.main_loop
