Terminating a thread from the parent

[DE]

Hello,

I have an app with embedded Python. Python scripts create their own
threads and I need to terminate these threads at the point where the
user wants to leave the application. I use threading.Thread as base
classes.

I have tried to use call the join method of the python thread objects
from C++. But although the call succeeds, the threads don't exit.

What is the proper way of doing this ? (e.g. how does the python shell
do this ? )

Thanks in advance,

Devrim.
