The if/else you are doing here is exactly what a StyleMap is used for. See the http://www.openlayers.org/dev/examples/styles-context.html example, especially the 2nd StyleMap with the functions in the context to see how to do that. > var styleSel = {fillColor: "#FC1797", strokeColor: "#FC1797", fillOpacity: > 0.5, strokeWidth: 2}; > > var myStyleMap = new OpenLayers.StyleMap({"default": style,"select": > styleSel}); > > var vector = new OpenLayers.Feature.Vector(geometry, record, myStyleMap); You cannot assign a StyleMap to the style argument of Feature.Vector. The third argument of Feature.Vector needs to be a plain symbolizer object (i.e. with just the fillColor, strokeColor or whatever properties) or a n OpenLayers.Style object, but not an OpenLayers.StyleMap. > > layer.addFeatures(vector); > > > > I try to assign a default style to each polygon and assign the selected > style to the OpenLayers.Layer.GML (it's always the same style), but in this > case the selected style is not shown: > > > var styleSel = {fillColor: "#FF7474", strokeColor: "#FF0000", fillOpacity: > 0.5, strokeWidth: 2}; > > var myStyleMap = new OpenLayers.StyleMap({"select": styleSel}); > > layerEditable = new OpenLayers.Layer.GML("Polygons", urlGML,{styleMap: > myStyleMap}); > > if (...)style = {fillColor: "#FCED97", strokeColor: "#FCE144", fillOpacity: > 0.5, strokeWidth: 2}; > > else if (...)style = {fillColor: "#000000", fillOpacity: 0.1, strokeColor: > "#000000", strokeWidth: 1}; > > var vector = new OpenLayers.Feature.Vector(geometry, record, style); This combination won't work. Either use a styleMap for both default and select styles (recommended), or use the style property of each feature for the default style plus the selectStyle property of OpenLayers.Control.SelectFeature for the select style. > layer.addFeatures(vector); > > > > Is there a way to assign differents styles in each polygon of a layer and a > selected style to the complete layer? As described above, the select style needs to be put into the selectStyle property of OpenLayers.Contorl.SelectFeature in this case.
