I am looking for example using Policy kit library with Qt. Please help.

Best Regards,

Its just as using any other lib with Qt.

Thank you for your answer. Could you tell me where I can find example for Policy kit library?
I write a program that need to perform several administrator tasks on Linux. Some one told me to use Policy kit library, but I cannot find any qt example for this library.
Please help.
