There doesn't seem to be much interest in a seperate library, so i have dropped that idea for now. Whoever is interested in using the widget can do it right now by taking the required source files from gpxview (i'd be helping with that). After two or three people have done that we can try to agree on a function set needed for a unversal map widget. And then i can make the library.

But i won't do that while i am the only user of such a map as i don't want to build something that only suits my own needs and thus isn't used/usable by anybody else.

What applications do you think need a map widget? Perhaps we can directly ask their authors. I already contacted the belltower author but never got a reply, so there's probably no interest.
