.. class:: wx.ZoomGestureEvent(GestureEvent)

   **Possible constructors**::

       ZoomGestureEvent(windid=0) -> None
       
   
   This event is generated when two fingers pinch the surface to zoom in
   or out.



   .. method:: __init__(self, windid=0)

      Constructor. 
                 


      :param `windid`: 
      :type `windid`: wx.WindowID




      :rtype: `None`     








   .. method:: GetZoomFactor(self)

      Returns the zoom Factor since the gesture started. 
                 

      Hence, starting of the gesture is considered as 1:1. A value greater than 1.0 means we should enlarge (or zoom in), a value less than 1.0 means we should shrink (or zoom out). 
                 

      :rtype: `float`








   .. method:: SetZoomFactor(self, zoomFactor)

      Sets the zoom Factor. 
                 


      :param `zoomFactor`: 
      :type `zoomFactor`: float




      :rtype: `None`     








   .. attribute:: ZoomFactor

      See :meth:`~wx.ZoomGestureEvent.GetZoomFactor` and :meth:`~wx.ZoomGestureEvent.SetZoomFactor`
