Hi Jürgen,
Thank you so much for your reply.
I got it working with your suggestion but I had to change this line:
pf.attributes = {strokecolor: "#123456", fillcolor: "#654321"};
to
pf.*style* = {stroke*C*olor: "#123456", fill*C*olor: "#654321"};
Anyway, I realize that now, the layer's render intent definition is not
working anymore. My expectation was that, although each feature vectors has
their own style definitions, once it got selected, the layer's selected
render intent would apply.
So here's my code, more detailed:
// create a select control
var selectControl = new OpenLayers.Control.SelectFeature(
[],
{clickout: true, toggle: false, multiple: false, hover: false, toggleKey:
"ctrlKey", multipleKey: "shiftKey"}
);
// create a layer and add it to map
// ////////////////////////////////////////////////////////////////////////
var layer_style = new OpenLayers.StyleMap({
"select": new OpenLayers.Style(OpenLayers.Util.applyDefaults({
*fillColor: "#626262",*
strokeColor: "#111111"},
OpenLayers.Feature.Vector.style["select"]))
});
var vectorLayer = new OpenLayers.Layer.Vector("layer", {
styleMap: layer_style,
renderers: ['SVG', 'VML', 'Canvas']
});
vectorLayer.events.on({"featureselected": function(e) {
console.log(e.feature);
}});
map.addLayer(vectorLayer); // map was created previously
// then I add a select control
map.addControl(selectControl);
selectControl.activate();
selectControl.setLayer(vectorLayer); // make layer "controllable"
// create the vector feature
var fv = new OpenLayers.Feature.Vector(linearRing); // lineaRing is an
instance of OpenLayers.Geometry.LinearRing created elsewere, not relevant
to this case
fv.style = {strokeColor: "#00FF00",* fillColor: "#0000FF"*, fillOpacity:
0.5}; // this works as expected
// add feature to layer
vectorLayer.addFeatures([fv]);
Because the layers styleMap states a render select intent to make fillColor:
"#626262" I was expecting the vector feature to have this fill color once
selected, but instead it remains as fillColor: "#0000FF"
Have any ideas how to specify a render intent to the Feature.Vector? I
tried to do it like this:
fv.style = new OpenLayers.StyleMap({
"default": new OpenLayers.Style(OpenLayers.Util.applyDefaults({
fillColor: "#FF0000",
strokeColor: "#919191",
fillOpacity: 0.5
}, OpenLayers.Feature.Vector.style["default"])),
"select": new OpenLayers.Style(OpenLayers.Util.applyDefaults({
fillColor: "#00FF00",
strokeColor: "yellow",
fillOpacity: 0.5}, OpenLayers.Feature.Vector.style["select"]))
});
But it appears that the OpenLayers.Feature.Vector object doesn't
accept an OpenLayers.StyleMap
object.
Thanks again.
Ruben
