Just realized that I was looking at an old source. ImageMapTypes don't
have a setMap method, so you'll need to use something more along the
lines of:
var TileOverlay = new google.maps.ImageMapType({...});
var TileOverlayIndex = map.overlayMapTypes.push(BuildingsLayer) - 1;
google.maps.event.addListener(map, 'maptypeid_changed', function () {
if (this.getMapTypeId() != google.maps.MapTypeId.ROADMAP &&
this.getMapTypeId() != google.maps.MapTypeId.HYBRID &&
TileOverlayIndex != -1) {
map.overlayMapTypes.removeAt(TileOverlayIndex);
TileOverlayIndex = -1;
}
else if ((this.getMapTypeId() ==
google.maps.MapTypeId.ROADMAP
|| this.getMapTypeId() == google.maps.MapTypeId.HYBRID) &&
TileOverlayIndex = -1)
TileOverlayIndex =
map.overlayMapTypes.push(BuildingsLayer) - 1;
});
