For example - just tried this code, and while the variable overview is
correct, the variable projection is undefined:
var mapCenter = new google.maps.LatLng(38.43, -98.17);
var myOptions = {
zoom: 5,
center: mapCenter,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
var overlay = new MyOverlay(map);
var projection = overlay.getProjection();
-----------------------------------
MyOverlay.js:
MyOverlay.prototype = new google.maps.OverlayView();
MyOverlay.prototype.onAdd = function() { }
MyOverlay.prototype.onRemove = function() { }
MyOverlay.prototype.draw = function() { }
function MyOverlay(map) { this.setMap(map); }
-----------------------------------
