[OpenLayers-Users] Some question to OpenLayers.Protocol.WFS.fromWMSLayer

[Marc Jansen]

Hi Kai,

a quick guess: have you tried setting the pixelTolerance-property of the 
hover-handler?

var xyz = new OpenLayers.Control.GetFeature(
  {
    protocol: OpenLayers.Protocol.WFS.fromWMSLayer(layer),
    hover: true,
    styleMap: style_obj1
    handlerOptions : {
      hover: {
        pixelTolerance : 10
      }
    }
  }
);

untested as usual.

Regards,
Marc
