title: Get mouse position of the QDragEnterEvent
body: <p>As the photo below shows, I want to get the mouse position on the canvas while dropping a QListWidgetItem to the canvas, this mouse position will facilitate to me getting the object I dropped the item on.</p>
  
  <p>More explanation: The dragging and dropping will be in my canvas class, I want to check if the dragging and dropping is from the QListWidgetItems, and if so it will get the current mouse position.</p>
