Handling Com Events in Python (was Python and Windows Scripting Host)

I thought it was pretty once I used DispatchWithEvents (thanks Mark H.) and
looked at the file lying in gen_py folder. After you have run gen_py look at
the file it has created that lies in the gen_py folder.
Open this file to find the required method signature and copy this to your
class.

The only problem I have here is that OnDocumentComplete (the most
interesting method) won't compile because the "defaultNamedNotOptArg" label
is unknown to Python. I don't know which module this is located in. Could
anyone help me out here?

Here's the code:

#
#   Ie test
#

import win32com


class EventHandler:
    def OnVisible(self, visible):
        global bVisibleEventFired
        bVisibleEventFired = 1
    def OnDownloadBegin(self):
        print "DownloadBegin"
    def OnDownloadComplete(self):
        print "DownloadComplete"
#    def OnDocumentComplete(self, pDisp=defaultNamedNotOptArg,
URL=defaultNamedNotOptArg):
#        print "documentComplete"


ie = win32com.client.DispatchWithEvents("InternetExplorer.Application",
EventHandler)
ie.Visible = 1
ie.Navigate("www.python.org")

while ie.Visible:
    pass

ie.Quit()
