OK, no answer from experts yet.

I can remember that I used this Ruby code for that task:

@changed_handler_id = self.signal_connect('changed') {|w|
  if @pda
    if w.active != -1
    i = w.active_text.to_i
    if i != (@major ? @pda.schem.major_grid : @pda.schem.minor_grid)
      if @major then @pda.schem.major_grid = i else @pda.schem.minor_grid = i end
        @pda.schem.active_grid = i if radio_button.active?
        @pda.redraw
      end
    end
  end
}

So active property of

can be used to detect if an item was selected from list.
