Roland, I think when you said in your original mail that the problem
occurred "When typing in the editor and compiling", everyone though
you meant you were getting compilation errors (so not just an
auto-completion issue).

If this is only about auto-completion in Qt Creator, then I think this
whole thread could have been much shorter.
