What are the requirements for using Google's GEvent?

Question

For a current project, we need to know when a Google map is done loading all of its tiles. I found the following question, which was for the same basic problem: register event "loadend" on layer

So now, we're using the code from that answer:

GEvent.addListener(mGoogleHybridLayer.mapObject, "tilesloaded", function() {
 console.log("Tiles loaded");
});

However, this gives a reference error for GEvent. Are there some extra requirements for using GEvent? Do we need to import it from somewhere?

I can't post code we're using, because there isn't any yet - even in the browser's debug console, GEvent is undefined.

Using Openlayers 2.11.

EDIT: maybe I should restate the question into one that can actually be answered: what are all the requirements for being able to use GEvent?

Answer 1

You can access a Gmap layer with openlayers through mapObject. See that example (and source code), which gives the ability to use gmap style.

You can try to access events through mapObject. Never tested.

By the way, the example I pointed out uses the version 3 of gmaps.
