Althougth I knew that polygons are clickable, I had problems when I
wanted to use it in my programming.
How do I collect the information I need when a polygon has been
clicked?
When a polygon has been created, I add this listener to it.
GEvent.addListener(polyShape, "click", function(overlayobject) {
map.openInfoWindowHtml(overlayobject, infotext);
var j = this.getVertexCount(); // get the amount of points
for (var i = 0; i<j; i++) {
polyPoints[i] = this.getVertex(i); // update polyPoints array
}
polyShape = this;
});
polyShape, overlayobject, infotext and polyPoints are variables. You
may use your own names.
