Cedet + Qt

On one of the Russian forums I was asked "Why Cedet doesn't work with Qt?" Answer is very simple - it works, but you need to make simple customization. Add following code into your initialization file, and Cedet begin to parse your code:
(add-to-list 'auto-mode-alist
'("/usr/include/qt4" . c++-mode))
"/usr/include/qt4" 'c++-mode)
(add-to-list 'semantic-lex-c-preprocessor-symbol-file
(add-to-list 'semantic-lex-c-preprocessor-symbol-file
Here is proof:
Emacs + Cedet + Qt
Thanks to Eric M. Ludlam for hint about semantic-lex-c-preprocessor-symbol-file variable.
Update (12/05/2009): It seems, that this approach will not work in fresh CEDET - I'm working on fix

Thanks for these posts. CEDET was a complete mystery to me before but now I can see it is a really useful thing. Looking forward to Emacs 24.

Could you kindly post all the relevant sections of your .emacs file that enables context sensitive help for Qt on emacs. I do have all the cedet, semantic and cogre packages installed on Debian/Lenny but cant get it to work with Qt.

Thank you for your great post!
But why does my emacs say "Symbol's value as variable is void: semantic-lex-c-preprocessor-symbol-file"?

Could you give me any help? Thank you very much!

It seems, that CEDET wasn't compiled properly. Please, take CEDET from CVS and compile according instructions
