Is there any listener to handle map completely loaded?

In my case, I need to get bounds from map, so I've done it this way:

google.maps.event.addListener(this.map, bounds_changed, this.mapLoaded);



mapLoaded: function() {

    google.maps.event.clearListeners(this.map, bounds_changed);



    var bounds = this.map.getBounds();



    this.collection.setBounds(bounds.getNorthEast(), bounds.getSouthWest());

    this.collection.fetch();

},

Is there any not-hacking way?
