getMetadata/KmlLayerMetadata

[this.me]

Good evening,

I am having the hardest time interpreting the API reference for
getMetadata.

Assuming my KmlLayer object is kmllayer, then:

kmllayer.getUrl() returns the Url, kmllayer.setMap(map) renders the
overlay on the map but kmllayer.getMetadata() returns undefined.

kmllayer.getMetadata.name returns blank,
kmllayer.getMetadata.description returns undefined.

Can anyone provide an example of the proper syntax for using
getMetadata?

Thanks much.

Also, there is an error in the example code under the KML Feature Data
at:
http://code.google.com/apis/maps/documentation/javascript/overlays.html#KMLLayers

The example reads:
google.maps.event.addListener(ctaLayer, 'click',
function(kmlEvent) ...

Unfortunately, ctaLayer is undefined. The actual layer should be
nylayer, as per the original declaration.

With my own testing, it appears that getMetadata only returns an
object after the layer has finished rendering. Intuitively this makes
sense. However the problem is there isn't an event directly designed
to tell you when this is ready. I was able to use the tilesloaded
event on the map to accomplish the same thing though.

map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
ctaLayer = new google.maps.KmlLayer('http://gmaps-
samples.googlecode.com/svn/trunk/ggeoxml/cta.kml');
google.maps.event.addListenerOnce(map, 'tilesloaded', function()
{ console.log(ctaLayer.getMetadata()) });
ctaLayer.setMap(map);

Chad, thanks, that worked great.

My only change was from 'tilesloaded' for the map to
"metadata_changed" for the layer, because of the API reference.

For some reason, I was unable to store getMetadata().name into a
variable, but if I call a function, sending getMetadata().name and
then storing the variable, it works. Guess that was my problem, but
you pointed me in the right direction.

Thanks much!
