How to consume COM events from python modules generated using makepy? I
instance of Test works but how to implement events?
class ITest(DispatchBaseClass):
'Dispatch-Interface for the Test object'
CLSID = IID('{F0691CAD-0C9D-4357-9373-CE6972E1F8A5}')
coclass_clsid = IID('{E4A22390-5A45-4217-AD46-EA4E4EBBEA79}')
...
...
...
def __iter__(self):
"Return a Python iterator for this object"
try:
ob = self._oleobj_.InvokeTypes(-4,LCID,3,(13, 10),())
except pythoncom.error:
raise TypeError("This object does not support enumeration")
return win32com.client.util.Iterator(ob, None)
class ITest_Events:
'Event-Interface for the Test objects'
CLSID = CLSID_Sink = IID('{7556E550-8FA7-424D-B9AD-600B9E8E983A}')
coclass_clsid = IID('{E4A22390-5A45-4217-AD46-EA4E4EBBEA79}')
_public_methods_ = [] # For COM Server support
_dispid_to_func_ = {
1 : "OnRunProject",
}
def __init__(self, oobj = None):
if oobj is None:
self._olecp = None
else:
import win32com.server.util
from win32com.server.policy import EventHandlerPolicy
cpc=oobj._oleobj_.QueryInterface(pythoncom.IID_IConnectionPointContainer)
cp=cpc.FindConnectionPoint(self.CLSID_Sink)
cookie=cp.Advise(win32com.server.util.wrap(self,
usePolicy=EventHandlerPolicy))
self._olecp,self._olecp_cookie = cp,cookie
def __del__(self):
try:
self.close()
except pythoncom.com_error:
pass
def close(self):
if self._olecp is not None:
cp,cookie,self._olecp,self._olecp_cookie =
self._olecp,self._olecp_cookie,None,None
cp.Unadvise(cookie)
def _query_interface_(self, iid):
import win32com.server.util
if iid==self.CLSID_Sink: return win32com.server.util.wrap(self)
# Event Handlers
# If you create handlers, they should have the following prototypes:
# def OnRunProject(self):
# 'This event is fired when the project starts to run.'
Any help will be much appreciated.
