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
@scriptFilename = scriptFilename
@fieldsFilename = fieldsFilename

 super()

end

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

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

app = WebRecorderApp.new(nil, nil, nil)
app.main_loop
