Code Completion fail when using iterator

Hi Experts:

I start to use Qt when I saw the smart code completion in some demonstration video, for me it is a very very good feature.
However, recently i found that the code completion do not work with iterator.
for example:
If I create an iterator:
QString* test_string;
QString::Iterator it=test_tring->begin();

then when i use (*it) to retrieve the object, no method/member show up, actually no auto-coplition menu show up, no matter i do (*it). or (*it)->
But the auto completion works perfectly with pointer.

This problem also happens for std::vector::iterator.

Hopes that you will fix them soon.

Thank you very much for developing such a powerful tools.

Cheers
Zhili
