Some questions while I go ahead:

1. How should own headers be included, what is preferred?
#include <kparts/part.h>
or 
#include "part.h"

And both the same in the public headers and in the normal sources? Myself I 
also use the second version, but I found a mixture in use, so wonder if one is 
preferred/recommended in the frameworks.


2. How to do KDE4-compatibility for moved header content?

E.g. in event.h for KDE4-compatibility the declarations which have been moved 
to their own headers would need to be pulled in again, at least for builds 
using KDE4Support
Is that done by having includes in the normal file, guarded by a flag, like

// KDE4 compat
#if KDE4COMPATIBLE
#include <kparts/guiactivateevent.h>
#include <kparts/partactivateevent.h>
#include <kparts/partselectevent.h>
#endif

If so, which flag?

Or is there another way?

Cheers
