[OpenLayers-Users] Can't define hover behavior on a Feature.Vector or a Layer.Vector

[mail.roliveira at gmail.com]

Hi Diego,
Thank you for you answer.
That was my first approach.I realized that:
var fv = new OpenLayers.Feature.Vector(linearRing, {}, {strokeWidth: "#123456" ,strokeColor: "#123456", fillColor: "#123456", fillOpacity: "#123456"})
;is the same as:
var fv = new OpenLayers.Feature.Vector(linearRing);fv.style = {strokeWidth: "#123456" ,strokeColor: "#123456", fillColor: "#123456", fillOpacity: "#123456"}

;The thing is, I'm only defining one style. What I need is a style for "default" and a style for "select" but  OpenLayers.Feature.Vector doesn't support an OpenLayers.StyleMap like the OpenLayers.Layer.Vector does. If an OpenLayers.StyleMap was supported I could define a renderIntent and therefore maybe implement the select behaviour.

Why you can't define a stylemap for "default" feature visibility?
You need some computation inside the loop to build a style for the feature?

Anyway, try to pass the style as a Style objectdirectly in the Vector
constructor, ie:
var yourstyle = new Openlayers.Style({strokeWidth: "#123456"
,strokeColor: "#123456", fillColor: "#123456", fillOpacity:
"#123456"})
;var fv = new OpenLayers.Feature.Vector(linearRing, {/*empty
attributes*/, yourstyle)
