[python-win32] attaching an event handler to already created object
Hello,
I am trying to attach an event handler to a running pythoncom object.
The problem is I am not instantiating it via Dispatch. Basically I generated
the python wrapper code (via makepy), and renamed it to a specific name, say,
SignpadActivex.
The code is the following:
"""
import os, sys
import win32com
import SignpadActivex
class MyEvents():
def OnPenDown(self):
print 'evt pendown'
self.m__signpad.SetEventEnableMask(7)
def OnPenUp(self):
print 'evt penup'
self.m__signpad.SetEventEnableMask(7)
def OnPenPoint(self):
print 'pen point'
self.m__signpad.SetEventEnableMask(7)
class SignPad():
def __init__(self):
self.m__signpad = None
def createControl(self):
self.m__signpad = TopazSigPlus.SigPlus()
print dir(self.m__signpad)
win32com.client.WithEvents(self.m__signpad, MyEvents)
self.m__signpad.SetEventEnableMask(7)
if __name__ == '__main__':
l__obj = None
l__resp = raw_input('enter option ...:')
while l__resp != 'x':
if l__resp == 'c':
l__obj = SignPad()
l__obj.createControl()
l__resp = raw_input('enter option ...:')
"""
Because I do instantiate this way, I dont have the DispatchWithEvents method.
So I dont know how to add MyEvents event handler class managing the control's
events.
>From the generated python code I got this:
"""
# This CoClass is known by the name 'SIGPLUS.SigPlusCtrl.1'
class SigPlus(CoClassBaseClass): # A CoClass
# SigPlus Control
CLSID = IID('{69A40DA3-4D42-11D0-86B0-C025864A}')
coclass_sources = [
_DSigPlusEvents,
]
default_source = _DSigPlusEvents
coclass_interfaces = [
_DSigPlus,
]
default_interface = _DSigPlus
"""
So basically how do I attach an event handler to that running object ?
Thank you !

You can pass an existing IDispatch object to DispatchWithEvents as the first arg in place of a clsid. Roger ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32

Try replacing self.m__signpad = TopazSigPlus.SigPlus() with self.m__signpad = win32com.client.DispatchWithEvents(TopazSigPlus.SigPlus(), MyEvents) Roger Patricio Eduardo Stegmann wrote: > Hi Roger, > > could you please be a bit more specific ? > > > - Original message - >> You can pass an existing IDispatch object to DispatchWithEvents >> as the first arg in place of a clsid. >> >> Roger >> >> >> >> ___ >> python-win32 mailing list >> python-win32@python.org >> http://mail.python.org/mailman/listinfo/python-win32 >> > > ___ > python-win32 mailing list > python-win32@python.org > http://mail.python.org/mailman/listinfo/python-win32 > ___ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
