NetworkManager D-Bus Interface in C++ and Qt

[Luis Iván <luisivan luisivan nom es>]

Hello, I want to add NetworkManager D-Bus Interface to my project 
(http://gitorious.org/yeos).
I saw the official specification 
(http://projects.gnome.org/NetworkManager/developers/spec.html) and I 
made tests, but I can't use the NetworkManager D-Bus Interface in my 
project.
I have the NetworkManager libs installed on Ubuntu 9.04 Jaunty, and I am 
working in C++ with the Qt libraries.
I saw the code of nm-applet and KNetworkManager but they need other 
extra libraries.
Can you put me a code example of how use the NetworkManager D-Bus 
Interface in C++ with Qt libraries?
Thanks for your attention,
Luis Iván Cuende
