Look at win32com.client.DispatchWithEvents().
Create a class that, for every event you're interested in, has a
method named MyClass.On<eventname>
Call DispatchWithEvents, passing it the CLSID/ProgId of the COM server you're
interested in, *and* the event-handling class object.
DispatchWithEvents will return an object that (effectively) inherits from both
the COM server and your event-handling class, and this object's proper
methods should be called when the COM object fires an event.
This is a simplification, of course, as the framework scheme that supports
this seems to be *very* complex. Digging through the docstrings and comments
in win32com.client should help explain more details. But hopefully this
general overview will be helpful. :)
