This event is fired after all tiles required to render the map have been fetched, and all labeling is complete.
Note that this event is fired only at once.

var div = document.getElementById("map_canvas");

map.one(plugin.google.maps.event.MAP_READY, function() {
map.on(plugin.google.maps.event.MAP_LOADED, function() {
alert("Map tiles are loaded");
});
