Thanks for your Welcome, and your answer ! (from France...) :)

Have you a link, to show it or a short script example ? ( hi hi : a kind of "hello world" with the new icon)
Me, at the same time, i will soon looking for in the web, this function " setIconFromFile() " ;-)
In fact, i'm not (yet...) an OOP user (very noob, i say ;-) )

Regards.
