title: OpenLayers: value of Event parameter in OpenLayers.Event.triggerEvent
body: <p>I'm looking at the
  <a href="http://dev.openlayers.org/releases/OpenLayers-2.11/doc/apidocs/files/OpenLayers/Events-js.html#OpenLayers.Events.triggerEvent" rel="nofollow">documentation</a>
  for triggering events in <strong>OpenLayers</strong>. It lists <code>triggerEvent</code> as taking in a <code>type:String</code> argument and a <code>evt:Event</code> argument. I understand what the <code>type</code> parameter is, but what object is the <code>Event</code> object? I can't find a clear example.</p>
  
  <p>If it is relevant, I am working on an interface between <strong>Google Maps v3</strong> and <strong>OpenLayers</strong>, and I'm trying to come up with a way so that I can have a the same API interface to calls to:</p>
  
  <ul>
  <li><code>google.maps.event.trigger(instance:Object, eventName:String, var_args:*)</code></li>
  <li><code>openLayersObj.events.triggerEvent(type:String, evt:Event)</code></li>
  </ul>
