But it works fine without the custom map. Why?
function init() {
...
var map = new GMap2(document.getElementById("map"));
var customTileLayers = [new GTileLayer(...)];
customTileLayers[0].getTileUrl = customGetTileUrl;
var customMap = new GMapType(customTileLayers, new
GMercatorProjection(12)...);
//---------------------- test w/o customMap
-------------------------
// map.addMapType(customMap);
// map.setCenter(new GLatLng(0, 0), 3, customMap);
map.setCenter(new GLatLng(0, 0), 3);
//-------------------------------------------------------------------------------
// I will skip explanation up to this point. It is just a routine
for custom map.
GEvent.addListener(map, "click", function(overlay, latlng) {
var lat = latlng.lat();
var lon = latlng.lng();
var latOffset = 10;
var lonOffset = 10;
var polygon = new GPolygon([
new GLatLng(lat, lon - lonOffset),
new GLatLng(lat + latOffset, lon),
new GLatLng(lat, lon + lonOffset),
new GLatLng(lat - latOffset, lon),
new GLatLng(lat, lon - lonOffset)], "#f33f00", 5);
map.addOverlay(polygon);
});
}
}
