title: QTooltip display position
body: <p>I've added a <code>QTooltip</code> on a <code>mouseMoveEvent</code> for my widget. This tooltip is being displayed way above my mouse cursor.</p>
  
  <pre><code>void myWidget::mouseMoveEvent(QGraphicsSceneMouseEvent *event)
  {
  
    QToolTip::showText(event-&gt;scenePos().toPoint(),
                         QString::number(event-&gt;scenePos().x()) + ", "
                         + QString::number(event-&gt;scenePos().y()));
  
    QGraphicsScene::mouseMoveEvent(event);
  }
  </code></pre>
  
  <p>How do I customize the tooltip's position w.r.t my cursor? I want to display this tooltip just below my cursor.</p>
