You can sort a QValueList with the qHeapSort() method. For using this method
KABC::Addressee would have to provide an
	operator>(const Addressee&)
and
	operator<(const Addressee&)

I think that's the best idea. My above mentioned has the disadvantage that
you can sort for only one specific part of addressee.

If you have questions feel free to ask me.
