You have to determine the geometry type, and use OpenLayers.Renderer subclasses (test browser compliance using each renderer's supported method) with a resolution of 1. You need a vector feature representing your geometry type (a polygon, a line, a point) that you render along with the name or title of the rule. No need to dig into GeoExt sources a lot. It's all in http://trac.geoext.org/browser/core/trunk/geoext/lib/GeoExt/widgets/FeatureRenderer.js and http://trac.geoext.org/browser/core/trunk/geoext/lib/GeoExt/widgets/VectorLegend.js Regards, Andreas.
