Well, at first I thought you still insisted on a special extension.
Sorry if I overreacted.

I would like .h as default extension.
I've do a short find | grep | wc for Q_OBJECT in .h files on my local
sandboxes. I found 1528 header files which needs moc'ing.
All headers CVS-Controlled. (Some .ui generated, but still...)
And believe, it is no fun to "simply" rename files in CVS. Ask the
boost-CVS maintainers or the list archive for examples. The worst I
remember was renaming is_POD.hpp to is_pod.hpp.
Please consider that many possible users have a running setup (qmake,
old tmake, even handcraftet Makefiles, MSVC-Projects using the
Qt-Visual Studio binding, ...) All these depend on .ui -> .h ->
moc_.cpp Depencies.

Just to be sure: The .hpp approach is acceptable if you start fresh. I
my (and many other cases) you have so much legacy code lying around
which simply need the prefix .h .
Naturally, the extension should be made to be customised.
But Qt uses .h everywhere, so it seems best, not to change this...

Oh sorry, this is a clear misunderstanding. I was focused on the moc
issue. We're just using doxygen with the standard doxygen configuration
file. I would be glad if someone could improve this, because generating
docs by "grab all and run...." is not the best thing to do...

BTW, sourceforge seems to up again for me too. Strange thing, that.
