Thanks, but this is not quite necessary. Markers are interactive, as such, they have mouse event handlers including a Click event handler. So clicking on a marker will be trapped by a handler in my subclass.
In short, what I am trying to do is locate the code that allows editing tools to be drawn in the map in a selection or highlight layer, still trying to figure this all out. If I can locate that code, I might be able to enhance it to handle my marker layer instead of just the regular feature layers that it seems to be limited to handling.
Do you have any idea where in the MapSuite toolkits I might find code that would allow line or polygon drawing to be done? That would surely speed me on my way.
Thanks anyway for your kind suggestions.
