COM object pointer cast

[Axel Bock]

Hi,

I am fooling around with the Python-COM bridge, and I have a little
question with that.

In the component I am using is a method which will return an "Entry"
object - basically. In truth it returns some object which inherits from
entry, and I know which one, but - as said - the method will only
return the IEntry interface pointer. Now I would like to cast that one
to the one I need . Is there an easy way to do it, or do I have to
use the QueryInterface-method to get what I want?


Greetings & thanks in advance,

Axel.

There's an easy way - use win32com.client.CastTo(). See the
convert_tracks.py script on this page -

example.
