You are about the third team to do this (you can check the email archive for disucssions in 2006 for example).
Please review the source code for the tracking tutorial it should give you an idea of how to proceed. - listen to the points and update your own "domain specific" data structure on the map blackboard - create a mapgraphic to draw your data structure - as your domain model changes you can ask your mapgraphic layer to "refresh" Here is the wiki page: - http://udig.refractions.net/confluence/display/DEV/2+Training+Materials#2TrainingMaterials-Tracking The example also covers the creation of a very minimual udig "core" suitable for mixing in with an existing RCP application (ie no contributions to menus etc...). There is all an experimental "glass pane" you can try; it uses the SWT Draw2D api rather than the Java Graphics2D so it has "different" performance characteristics. It may be a bit faster; but you have to take up the display thread to do it making your application less responsive in total :-) Jody PS. For more information on the tracking example take our happy commercial training course :-) On Mon, Mar 30, 2009 at 1:23 PM, Mr R08040 <[email protected]> wrote: > Hi folks, > > First off, thanks for a great product!
