Thanks for the reply. I see whet your saying, I need to know the
segment of the polyline to know when to break out of my loop when
adding up all the distance segments.
function handleMouseOverPolyLine()
{
var nDistance = 0;
var nLastVertex = 0;
for(var i = 0; i < myPolyline.getVertexCount() && ([NOT THE
SEGEMENT THE MOUSE IS ON]); i++)
{
if(i > 0){ nDistance += myPolyline.getVertex(i).distanceFrom
(myPolyline.getVertex(i-1)); }
nLastVertex = i;
}
nDistance += [distance from the myPolyline.getVertex(nLastVertex)
to the mouse point];
}
the handler receives 1 param of value 0, not sure what this does but
it doesn't help.
Hmm this looks really messy and far from an ideal solution. Perhaps I
should rethink what I am trying to do...
