title: QGraphicsItem - Follow the mouse cursor
body: <p>I'm stuck on how to approach this. I have a QGraphicsItem within a scene, and I'm passing a hover event from the scene to this child. While the move event occurs (I'm just using mouseMoveEvent with mouse tracking on), I want another QGraphicsItem to follow the cursor. </p>
  
  <p>I don't need any collision detection, drag and drop, etc. Just an item that follows the cursor. The only two ways I can think of are...</p>
  
  <ol>
  <li>While the mouse moves, draw a new QGraphicsItem at the mouse position. I would need to clear the scene, redraw everything, and draw the new position on top. </li>
  <li>Somehow use the animation framework and whenever the mouse moves, animate the QGraphicsItem to move to the new mouse position in 1 millisecond.</li>
  </ol>
  
  <p>I'm probably either overthinking this or unaware of another way to do this... any suggestions? </p>
