[Qt-creator] QtCreator can't resolve QT names

[Sebastian Moors]

Hi!!

I'm encountering a small problem with different versions of QtCreator. 
All Qt type names are not recognised anymore. If i hover over a type 
name, let's say "QString", it says: "QString is not a namespace or type 
name". Adding my QT include path to project.includes didn't helped.  The 
file looks like this:

trunk
/opt/local/libexec/qt4-mac/include/

(I'm on Snow Leopard)
The build works, so qmake seems to know where the headers are..
Could you point me to a place where i can define the files which the 
editor should parse?
