Finding the polygon/polyline segment at a certain position

["Till Harbaum / Lists" <lists harbaum org>]

Hi,

i really enjoy working with goocanvas. One thing i have asked for some time ago
was a mechanism to figure out which segment of a polyline or polygon border 
a certain position is on. osm2go needs this to add new nodes to a way (being
a polyline) or to cut a way into two. So i have added such a function to osm2go.

For the records: If you need something like that have a look at canvas_item_get_segment()
in canvas_goocanvas.c in one of the later osm2go tarballs at 
http://repository.maemo.org/extras/pool/chinook/free/source/o/osm2go/

I've seen that the goocanvas main page links to projects using goocanvas. You might
