Sending events from custom controls

I'm trying to create a custom control which acts as a slider and sends
wxEVT_COMMAND_SLIDER_UPDATED events, but I haven't been able to figure out
the correct way of doing so.

I looked at the wiki page on custom controls
(http://wiki.wxpython.org/index.cgi/BuildingControls) and based on that
tried (within the custom control):

            evt = wxCommandEvent(self.GetId(), self.GetValue())
            self.GetEventHandler().ProcessEvent(evt)

I figured I must need to set the event type, but the documentation on
creating events like this seems poor. I tried:

            evt = wxCommandEvent(self.GetId(), self.GetValue())
            evt.m_eventType = wxEVT_COMMAND_SLIDER_UPDATED
            self.GetEventHandler().ProcessEvent(evt)

Which doesn't work either. I'm not sure whether I'm misunderstanding the
process, or just failing to create the right event object.

It should be something like this:

  evt = wxCommandEvent(wxEVT_COMMAND_SLIDER_UPDATED, self.GetId())
  evt.SetInt(self.GetValue())
  evt.SetEventObject(self)
  self.GetEventHandler().ProcessEvent(evt)
