How to receive events (eg. user mouse clicks) from IE

[Roger Upole]

Here's a few more lines that hook the document's onactivate event.

import win32com.client

ie_mod=win32com.client.gencache.EnsureModule('{EAB22AC0-30C1-11CF-A7EB-0000C05BAE0B}' 
,0, 1, 1)
doc_mod=win32com.client.gencache.EnsureModule('{3050F1C5-98B5-11CF-BB82-00AA00BDCE0B}' 
,0 ,4, 0)
class IE_Events(ie_mod.DWebBrowserEvents2):
    def OnNavigateComplete2(self, pDisp, URL):
        print 'OnNavigateComplete2:', URL

class Doc_Events(doc_mod.HTMLAnchorEvents):
    def Ononactivate(self):
        print 'onactivate', self.activeElement.outerHTML

ie=win32com.client.DispatchWithEvents('InternetExplorer.Application',IE_Events)
ie.Visible=1
ie.Navigate('http://www.google.com')

d=win32com.client.DispatchWithEvents(ie.Document, Doc_Events)
