OpenLayers：OpenLayers.Event.triggerEvent中的Event参数的值

Question

I'm looking at the documentation for triggering events in OpenLayers . It lists triggerEvent as taking in a type:String argument and a evt:Event argument. I understand what the type parameter is, but what object is the Event object? I can't find a clear example.

If it is relevant, I am working on an interface between Google Maps v3 and OpenLayers , and I'm trying to come up with a way so that I can have a the same API interface to calls to:

• google.maps.event.trigger(instance:Object, eventName:String, var_args:*)
• openLayersObj.events.triggerEvent(type:String, evt:Event)

Answer 1

Doc is wrong. It should be Event || object Event || object . Object that will be args passed to the listeners callback.

Look at the source: https://github.com/openlayers/openlayers/blob/master/lib/OpenLayers/Events.js#L820 Example of use: https://github.com/openlayers/openlayers/blob/master/lib/OpenLayers/Map.js#L1042
