class_docstr: Instances of this class are delivered to items in a :class:`GraphicsScene <pyqtgraph.GraphicsScene>` via their hoverEvent() method when the mouse is hovering over the item.
  This event class both informs items that the mouse cursor is nearby and allows items to 
  communicate with one another about whether each item will accept *potential* mouse events. 
  
  It is common for multiple overlapping items to receive hover events and respond by changing 
  their appearance. This can be misleading to the user since, in general, only one item will
  respond to mouse events. To avoid this, items make calls to event.acceptClicks(button) 
  and/or acceptDrags(button).
  
  Each item may make multiple calls to acceptClicks/Drags, each time for a different button. 
  If the method returns True, then the item is guaranteed to be
  the recipient of the claimed event IF the user presses the specified mouse button before
  moving. If claimEvent returns False, then this item is guaranteed NOT to get the specified
  event (because another has already claimed it) and the item should change its appearance 
  accordingly.
  
  event.isEnter() returns True if the mouse has just entered the item's shape;
  event.isExit() returns True if the mouse has just left.
docstr: Return the previous position of the mouse in the coordinate system of the item
  that the event was delivered to.
