Thank you very much for your answer, your exhibit is really nice !
(Unfortunately I cannot show you my exhibit as it is password
protected for the moment due to sensitive data)
I did some modification to my code according to your previous message
as you can see below
<script>
var map;
var oldMapViewReconstruct = Exhibit.MapView.prototype._reconstruct;
Exhibit.MapView.prototype._reconstruct = function() {
oldMapViewReconstruct.call(this);
map = this._map;
circ = new GGeoXml("/circonscriptions/chicago3.kml");
map.addOverlay(circ);
};
function newMapConstructor(mapDiv) {
map = new GMap2(mapDiv);
map.setCenter(new GLatLng(38.788345,-95.273437), 4);
map.addControl(new GLargeMapControl3D());
//map.addControl(new GMenuMapTypeControl());
map.addControl(new GMapTypeControl());
map.addControl(new GScaleControl());
map.addMapType(G_PHYSICAL_MAP);
map.setMapType(G_NORMAL_MAP);
map.enableScrollWheelZoom();
map.enableContinuousZoom();
//map.addOverlay(new GLayer("com.panoramio.all"));
//map.addOverlay(new GLayer("org.wikipedia.en"));
return map;
}
</script>
But the KML overlay still does not appear on the map. While this KML
file is displayed fine when I load it in a html file :
http://www.france-science.org/map/map3.html. So I guess the KML file
is ok.
Any idea of what I could have done wrong ?
