Up to now only in my printing style (which isn't committed, but it's already 
usable). It could very well be used for solving a problem with the other 
existing printing styles: if you print "Selection" the printed entries are 
sorted just like the view is sorted, but if you print "All entries" the 
sorting is undefined. Right now there's no really satisfying way to sort a 
list of addressees (the way I see it) except for the sorting eg the QListView 
does.

If I didn't get this wrong, the only sorting done in KAddressBook is done in 
the views. However, applications or printing styles may need to sort lists of 
addressees by different criteria without using a list view for it or caring 
about the order the user had in his view. 

Using qHeapSort would only work for at most one criterion, if operators< and > 
were implemented; however, you might want to sort by family name, given name 
etc.

The usage of QValueList<AddresseeList> that exists right now can easily be 
replaced by AddresseeList. The sorting stuff in the views doesn't have to be 
changed as it works just as well; however, for new types of views, which do 
not have a widget implementing sorting (like QListView) it might come handy.
