So, tired of always seeing the bright orange default regular polygons, I'm trying to learn to style OpenLayers.
I've had some success with:
var layer_style = OpenLayers.Util.extend({},OpenLayers.Feature.Vector.style['default']);
layer_style.fillColor = "#000000";
layer_style.strokeColor = "#000000";
polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer");
polygonLayer.style = layer_style;
But sine I am drawing my polygons with DrawFeature, my style only takes effect once I've finished drawing, and seeing it snap from bright orange to grey is sort of disconcerting. So, I learned about temporary styles, and tried:
var layer_style = new OpenLayers.Style({"default": {fillColor: "#000000"}, "temporary": {fillColor: "#000000"}})
polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer");
polygonLayer.style = layer_style;
This got me a still orange square--until I stopped drawing, when it snapped into completely opaque black. I figured maybe I had to explicitly set the fillOpacity...no dice. Even when I changed both fill colors to be pink and blue, respectively, I still saw only orange and opaque black.
I've tried messing with StyleMaps, since I read that if you only add one style to a style map, it uses the default one for everything, including the temporary style.
var layer_style = OpenLayers.Util.extend({}, OpenLayers.Feature.Vector.style['default']);
var style_map = new OpenLayers.StyleMap(layer_style);
polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer");
polygonLayer.style = style_map;
That got me the black opaque square, too. (Even though that layer style works when not given to a map). Passing the map to the layer itself like so:
polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer", style_map);
Didn't get me anything at all. Orange all the way, even after drawn.
polygonLayer = new OpenLayers.Layer.Vector("PolygonLayer", {styleMap: style_map});
Is a lot more succesful: Orange while drawing, translucent black with black outline when drawn. Just like when I didn't use a map. Problem is, still no temporary...
So, I tried initializing my map this way:
var style_map = new OpenLayers.StyleMap({"default": layer_style, "temporary": layer_style});
No opaque square, but no dice for the temporary, either... Still orange snapping to black transparent. Even if I make a new Style (layer_style2), and set temporary to that, still no luck. And no luck with setting "select" style, either.
What am I doing wrong? Temporary IS for styling things that are currently being sketched, correct? Is there some other way specific to the drawFeature Controller?
Edit: setting extendDefault to be true doesn't seem to help, either...
var style_map = new OpenLayers.StyleMap({"default": layer_style, "temporary": layer_style}, {"extendDefault": "true"});
