Hi ihr alle! Habe folgendes Problem: from time import sleep from win32com.client import Dispatch searchurl = ... msie = Dispatch('InternetExplorer.Application.1') msie.Navigate(searchurl) while msie.Busy: sleep(0.05) doc = msie.Document formelems = doc.getElementsByTagName('input') for idx in xrange(formelems.length): formelem = formelems(idx) if formelem.type.lower() == 'submit': button.onclick = <ACTION> Was hier passieren soll: Internet Explorer wird "ferngesteuert", sobald das Dokument da ist, wird hiner alle Buttons ein Eventhandler für Klicks gehängt. Problem: Wie "verpack" ich die Eventhandler!? Hat jemand sowas schon mal gemacht oder kann mir da weiterhelfen? (Diskussion in comp.lang.python streifen das Thema, kommen aber nie richtig zur Sache) Florian _______________________________________________ Python-de maillist - Python-de@starship.python.net http://starship.python.net/mailman/listinfo/python-de

In $PREFIX/Lib/site-packages/win32com/client/__init__.py gibt es u.a. die Funktion def DispatchWithEvents(clsid, user_event_class) mit einem Beispiel, um Events abzufangen. Es wird eine Klasse benötigt wie die folgende: (siehe $PREFIX\Lib\site-packages\win32com\gen_py\EAB22AC0-30C1-11CF-A7EB-0000C05BAE0Bx0x1x1.py für Details) class IWebBrowserEvents2: "Web Browser Control events interface" # Handlers for the control # If you create handlers, they should have the following prototypes: # def OnWindowSetTop(self, Top=defaultNamedNotOptArg): # """Fired when the host window should change its Top coordinate""" # def OnStatusTextChange(self, Text=defaultNamedNotOptArg): # """Statusbar text changed.""" # def OnWindowClosing(self, IsChildWindow=defaultNamedNotOptArg, Cancel=defaultNamedNotOptArg): # """Fired when the WebBrowser is about to be closed by script""" # def OnFileDownload(self, Cancel=defaultNamedNotOptArg): # """Fired to indicate the File Download dialog is opening""" # def OnStatusBar(self, StatusBar=defaultNamedNotOptArg): # """Fired when the statusbar should be shown/hidden""" # def OnWindowSetResizable(self, Resizable=defaultNamedNotOptArg): # """Fired when the host window should allow/disallow resizing""" # def OnNewWindow2(self, ppDisp=defaultNamedNotOptArg, Cancel=defaultNamedNotOptArg): # """A new, hidden, non-navigated WebBrowser window is needed.""" # def OnDownloadComplete(self): # """Download of page complete.""" # def OnBeforeNavigate2(self, pDisp=defaultNamedNotOptArg, URL=defaultNamedNotOptArg, Flags=defaultNamedNotOptArg, TargetFrameName=defaultNamedNotOptArg, PostData=defaultNamedNotOptArg, Headers=defaultNamedNotOptArg, Cancel=defaultNamedNotOptArg): # """Fired before navigate occurs in the given WebBrowser (window or frameset element).

Danke, funktioniert wunderbar. Folgendes Problem bleibt: [...] class ButtonHandler(html.HTMLButtonElementEvents): def __init__(self, button, oldevt = None): self.button = button self.oldevt = oldevt html.HTMLButtonElementEvents.__init__(self, button) def Ononclick(self): [... any action ...] if self.oldevt: classdiag(self.oldevt) self.oldevt() <----------------------- ????????????????? tagset = doc.getElementsByTagName('input') for idx in xrange(tagset.length): tag = tagset(idx) if tag.type.lower() in ('submit', 'button', 'reset'): oldevt = getattr(tag, 'onclick', None) bhandler = ButtonHandler(tag, oldevt) if oldevt: tag.onclick = u"" Es soll um folgendes gehen: Hinter alle Buttons wird ein EventHandler gelegt, ein eventuell schon vorhandener wird "stillgelegt". Nun soll aber, nachdem der Handler seine eigenen Jobs erledigt hat, der alte (abgelegt in self.oldevt) noch aufgerufen werden. Was ist die Syntax dafür? self.oldevt() liefert einfach einen String mit textueller Repräsentation, .Fire() und .Invoke() gibts nicht.
