Forum: wxRuby Registering custom events

Hi everyone,

I'm using the following code to try and register custom events:

When the commented line is uncommented, I the program crashes.
I'm running on windows xp.

Anyone know what am I doing wrong?

Thanks,
Idan.

require 'wx'

class CustomCommandEvent < Wx::CommandEvent

end

class RecorderFrame < Wx::Frame

  def initialize(parent, id, title, hwnds, scriptFilename, 
fieldsFilename)
    super(parent, id, title)
    @hwnds = hwnds
    @scriptFilename = scriptFilename
    @fieldsFilename = fieldsFilename

    layout = Wx::BoxSizer.new(Wx::VERTICAL)
    set_sizer(layout)

    @startButton = Wx::Button.new(self, Wx::ID_ANY, "Start")
    @stopButton = Wx::Button.new(self, Wx::ID_ANY, "Stop")
    @label = Wx::StaticText.new(self, Wx::ID_ANY, "Preparing...")

    @startButton.disable
    @stopButton.disable

    evt_button @startButton, :startTracing
    evt_button @stopButton, :stopTracing

    layout.add(@startButton, 0, Wx::ALL|Wx::EXPAND, 1)
    layout.add(@stopButton, 0, Wx::ALL|Wx::EXPAND, 1)
    layout.add(@label, 0, Wx::ALL|Wx::EXPAND, 1)

    evt_close { |event| onClose(event) }

    evt_custom_commands { |event| onCustomCommand(event) }

    show
  end

  def onCustomCommand(event)
    puts ("Received command event, id: #{event.inspect.to_s}")
  end

  def onClose(event)
    if (event.can_veto)
      #TODO: Constants
      confirm = Wx::MessageDialog.new(nil, "Are you sure you want to 
stop
recording?",  "Stop Recording", Wx::OK | Wx::CANCEL)
      case confirm.show_modal
      when Wx::ID_OK
        destroy
      when Wx::ID_CANCEL
         event.veto
       end
    else
      destroy
    end
  end

  def startTracing
  end

  def stopTracing
  end
end

class WebRecorderApp < Wx::App
   attr_reader :frame

   def initialize(hwnds, scriptFilename, fieldsFilename)
     @hwnds = hwnds

   def on_init
     @frame = RecorderFrame.new(nil, Wx::ALL, "Test", @hwnds,
@scriptFilename, @fieldsFilename)

#Wx::EvtHandler.register_class(CustomCommandEvent, nil,
"evt_custom_commands", 1)
