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))
(semantic-add-system-include 
"/usr/include/qt4" 'c++-mode)
(add-to-list 'semantic-lex-c-preprocessor-symbol-file
"/usr/include/qt4/Qt/qconfig.h")
(add-to-list 'semantic-lex-c-preprocessor-symbol-file
"/usr/include/qt4/Qt/qconfig.h")

Here is proof:

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
