Thanks for you answer ;).
Ok I understand I can give more than one argument to a callback function.
But my question remains, how can I access to my list.
windows is the pointer of my interface.
And my list is included in this interface.
Sorry I don't see how to proceed :( (in my callback function OnFile).

Cheers
