title: How can I set PATH variable using QT?
body: <p>How can I get and set PATH variable using QT 4.8? I know I can get PATH variable values using getenv from the STL but don't know how to set it using STL or any Qt based method?</p>
  
  <p>If QT has a function for it, I would like to know and use it rather than going and using Windows API for it.</p>
