title: Why cant I drop a file into the Qt Sample drop example?
body: <p>I am trying to get dropping a file into the application to work and so I compiled the <a href="http://qt-project.org/doc/qt-4.8/draganddrop-dropsite.html" rel="nofollow">example</a> but every time I try to drop a file, I get the "not allowed to drop" symbol. I tried this also with my own example and in debug mode I find that none of the implemented functions (dragEnterEvent, dragMoveEvent, dropEvent) are even reached. What is the problem here / how do I fix this?</p>
  
  <p>Also, running Qt 4.8 on Win7 x64</p>
