Thank you for this information, now it is clear why it not work with my way.

Yes, i did a review of the phpqt code for a while, but i think many things 
aren't solved nicely or i do not fully understand it.. but i cant get the 
phpqt code to work for me.. so i decided to start this mini project for a 
smoke based php binding, to get deeper into the matter and then i would to 
review the phpqt binding code again and will see if i understand every detail 
of it..

and maybe if i do that, then i will become a maintainer of the projekt :)
