I'm creating html5 mobile apps and I noticed that the idle, bounds_changed and tilesloaded events fire when the map object is created and rendered (even if it is not visible).

To make my map run code when it is shown for the first time I did the following:

google.maps.event.addListenerOnce(map, 'tilesloaded', function(){
    //this part runs when the mapobject is created and rendered
    google.maps.event.addListenerOnce(map, 'tilesloaded', function(){
        //this part runs when the mapobject shown for the first time
    });
});

If you're using the Maps API v3, this has changed.

In version 3, you essentially want to set up a listener for the bounds_changed event, which will trigger upon map load. Once that has triggered, remove the listener as you don't want to be informed every time the viewport bounds change.

This may change in the future as the V3 API is evolving :-)

GMap2::tilesloaded() would be the event you're looking for.

See GMap2.tilesloaded for references.
