The above tutorial provides general overview of Qt project objects hierarchy.

My inquiry is
is there a tool to analyze Qt project little deeper than what this tutorial shows?

Sort of traditional IBM flow chart would be a good start.
Maybe even pseudo-code ?

I am open to suggestions ,

EDIT
Looks as Doxygen would work, now if I can figure out how to add it as "plug-in" I'll be a happy camper.

PS
Why is it so difficult to add stuff to QtCreator? I can check all plug-ins. Yes, I have no Doxygen plug-in... How do I add it in - WITHOUT RECOMPILING EVERYTHING QtCreator ?
