title: QProcess user privilege elevation
body: <p>Is it possible to start a fully independant process with QProcess with elevated user privilleges?</p>
  
  <p>For example if my c++/qt application is run as a limited user, can my c++/qt application start another independant process with admin rights?  </p>
  
  <p>I am implying that the admin username and password is available inside the c++/qt application that is doing the launching of the 3rd party application.</p>
