This looks like the Document object implements IProvideClassInfo2 interface, but
IProvideClassInfo2::GetGUID() returns a NULL guid. comtypes should probably
catch this,
but the net effect is that one cannot determine the outgoing interface.
Fortunately, with a little bit browsing through the comtypes.gen.MSHTML module
(really the comtypes.gen._3050F1C5_98B5_11CF_BB82_00AA00BDCE0B_0_4_0 module)
and guessing I found that both the HTMLDocumentEvents or HTMLDocumentEvents2
interface seems to work, you just have to pass that interface to
GetEvents/ShowEvents.
This script works for me:
"""
from comtypes.client import CreateObject, GetEvents, ShowEvents, PumpEvents
ie = CreateObject("InternetExplorer.Application")
ie.Visible = True
ie.Navigate2("http://www.python.org";)
PumpEvents(1) # give the page a chance to load
doc = ie.Document
from comtypes.gen import MSHTML
print doc
evt = ShowEvents(doc, interface=MSHTML.HTMLDocumentEvents2)
PumpEvents(10)
"""
and here is some sample output:
