I don't really understand what you are saying... but I think I don't
have to use GGeoXml or EGeoXML for what I want to do. Actually, after
another visit to http://econym.org.uk/gmap/inside.htm I have found
what I need I think.
The only things I had to do : modify my kml file to a simple xml file,
removing some informations we don't especially need ; I shamelessly
copy the code he uses for an example (http://econym.org.uk/gmap/
example_states.htm) and modify what needed to be.
Here is the result :
http://boucard.brice.perso.neuf.fr/geoculture/geoloc/polytest.html
But I have a problem : I don't really understand this part of the code
except the first line and map.openWindow...
GEvent.addListener(map, "click", function(overlay,point) {
if (!overlay) {
for (var i=0; i<polys.length; i++) {
if (polys[i].Contains(point)) {
map.openInfoWindowHtml(point,"You clicked on "+labels
[i]);
//i = 999; // Jump out of loop
}
}
}
});
In fact I have tried to modify this part of the code to have a similar
result on a marker (in my code : visite) dragend event but it doesn't
work. I don't understand how the coordinates of the click point are
returned and then compared to the points inside the polygon.
Maybe it would be better if I open a new post ?
Thanks again for your help.
