my code completion don't work for iterators, f.e. iterator of std::vector. If i type in manually the code the project compiles fine. So compiler knows the iterators but the code completion doesn't.

example:
@
std::vector<tcpStruct>::const_iterator it;
it-> //code completion show nothing
it. //code completion show nothing
it->ip; //manually completed, compiling ok

I am using Qt Creator 3.2.1 as IDE for my QNX 650 project (QNX compiler & debugger, no Qt Kit) on a Ubuntu 12.04 System.
I setup my environment based on this Qt article: "link":http://qt-project.org/wiki/Setting-up-Qt-Creator-for-QNX
Compiling the project works fine. Also highlighting works fine, highlighter knows the "const_iterator".

I would be very happy if anyone can help me.
I assume there is only a path / any project configuration missing, but i don't find it yet.
Does anyone have an idea?
