title: Qt set custom drag cursor?
body: <p>How can I set the cursor used in Qt while performing a drag operation? I am using the <code>QDrag</code> class. The function <code>setCursor</code> takes a pixmap and has no way to specify the hotspot, nor do the docs specify that it could override the "no action" cursor.</p>
  
  <p>I'm happy if I can just do an explicit cursor in <code>mouseMoveEvent</code> but I'm not sure how during a drag operation.</p>
