I couldn't understand what you want to ask.
Although the following is one of the samples rewriting yours, 
it may not be able to answer your question.
===================================================================
require 'tk'

cash_locs=['NONE','NY1','NY2','NJ1','ETC.']

#--------------------------------
# callback function

def put_picked_value(s)
  puts 'USER PICKED: ' + s
end

#--------------------------------
# GUI part

Tk.root.title 'PICK LOCATION'

TkButton.new(:text=>'Quit', 
             :command=>proc{exit}).pack(:side=>:bottom, :fill=>:x)

f = TkFrame.new.pack(:fill=>:both, :expand=>true)

list = TkListbox.new(f)
list.yscrollbar(TkScrollbar.new(f).pack(:side=>:right, :fill=>:y))
list.pack(:side=>:left, :fill=>:both, :expand=>true)

list.insert(:end, *cash_locs)

list.bind('ButtonPress-1', 
          proc{|y| put_picked_value(list.get(list.nearest(y))) }, 
          '%y')

Tk.mainloop()
