I'm very sorry. 
Is the following the one of the samples which you want?
---------------------------------------------------
  map_st = TkVariable.new

    :

  ['Options', 
     ['Display Map', map_st, nil, nil, {:command=>proc{show_map()}}],
     ['Hide Map',    map_st, nil, nil, {:command=>proc{hide_map()}}]
  ]
