Well, you could easily arrange the polygons in the desired order by holding them in an array, sort the array by using the getArea() method, and addOverlay() in order, from large to small.
But still, IMHO, it is incorrect to say that a click in Dallas is not a click in Texas. :-) -- Marcelo - http://maps.forum.nu -- On Mar 14, 12:23 pm, Nick <[email protected]> wrote: > Thanks for the reply: > > > I don't know the specific needs of the application you're planning, > > but I see no reason why a click onDallasshould not be considered a > > click on Texas. > > My idea is that if they want Texas, they can click anywhere that isn't > Dallas.
