Which is listed in the Python cookbook, second edition. Is it possible

that window class or handle opens/closes. Can this recipe help with
that? Any ideas on getting started with this?
Do you mean a window in another application? That requires installing a
Windows hook, and a Windows hook callback must reside in a DLL (so that
DLL can be injected into the other process), which cannot be done in
Python. There is the pyHook package, but I don't know if it is still
being developed.

Thanks your reply.
I'm guessing from your response that the cookbook recipe can only deal
with open/close events that it throws itself. So far, the only way I
have found to monitor window open/close events is the Active
Accessibility (AA) layer via pyAA. The problem is that AA is really
dated and is theoretically supposed to be superseded by the UI
automation layer, but there are no similar Python bindings for that (and
it relies on the .NET framework ).
Here is the link for a description of pyAA:

Thanks!
