Class hierarchy diagram

[hpng]

Can someone point me to a link or documentation of Class hierarchy diagram?
It is a whole lot easier and faster to understand Qt classes if there is a diagram.

I know of this older one for "Qt 4.3":http://doc.qt.nokia.com/extras/qt43-class-chart.pdf but I haven't seen anything for any more recent versions.

If I remember correctly "doxygen":http://www.doxygen.org in conjunction with "graphviz":http://www.graphviz.org/ was able - or is able - to create class diagrams right from the sources. If you use doxywizard there should be an option for generating inheritance and collaboration diagrams.

I think the reason why there is no diagram above 4.3 is because it would be huge (even the 4.3 diagram seems huge to me).

I don't doubt it would be huge. Would still be nice to have one, though. I'm sure we'd have a poster-sized print hanging up here in our office if there was one available. If for no other reason than showing it off. :)

I'd consider using it as wallpaper for my room :)

A diagram with all 1000 or so classes on it would be... unreadable, I think. I think smaller, per module or group of classes that belong together maps would be much more useful.

As far as I'm concerned, class interaction is way more educating than class hierarchy.

We use doxygen with graphviz in our project made in Qt, you could very well use it on Qt itself. It should give you some diagrams and actually probably a complete API reference too.. considering the level of documentation Qt code has.
