title: QString vs qstring.h
body: <p>I finally got C++/QT projects in Eclipse working. But when I try to include e.g. QString I get only qstring.h offered in code completion, typing QString manually works though.</p>
  
  <p>I checked the QString file which simply includes qstring.h itself. But what is the reason for having such a file at all and not using qstring.h directly in the includes?</p>
  
  <p>Additionally is it possible to get the QString in the code completion of Eclipse as well?</p>
