      end
    end
    WindowProcess.spawn_gui f
  end
end

    f=frame id: :main_frame, react: [:close] do
      button id: :button, label: "Number of clicks: 0.", react: [:click]
    end
    pid=WindowProcess.spawn_gui f
    reaction pid
  end

  def reaction(pid) do
    continue=true
    receive_event do
      from pid: ^pid do
        from widget: :button do
          :click->
            label=send pid, :button, :get_label
            count=Regex.run(%r/[0-9]+/, label) |> List.first |> String.to_integer
            count=count+1
            label=Regex.replace %r/([0-9]+)/, label, to_string(count)
            send pid, :button, :set_label, label
        end
        from widget: :main_frame do
          :close->
