Oh, I should have mentioned that this child class uses
the same event type as the parent.  I did that so that
you could make one handler that catches all network
events.  The downside of that is that each handler
that DIDN'T want every event would need a:

Event.Skip()
if not isinstance(Event, DesiredEventClass):
    return

in their event handler.  If you didn't want one
handler capable of catching all types of events, then
you'd want to put a:

Type = wx.NewEventType()

in each child event definition as well as the parent.
