Thanks for the explanation. Even though I have been using KDE4.X since April I 
still don't grasp a lot of the inner workings and I guess I still have to read 
a lot of code and experiment on my own before I'm half way there ;-)
I understood in principle what you wrote but cannot think of an example where 
I have seen it in use. If I where given an example I hope my response would be 
"Ahhh - now I understand" :-D
