Joe, You can't. You can only use it with Vector features. If you're planing to use WMS only, you can use the GetFeatureInfo control triggering requests when the mouse stops for a brief moment and display a div with the name of the feature hovered.
Here's an other solution (still using WFS to get and draw vector features though, you'll need to make sure that you have a WFS server setup): http://www.openlayers.org/dev/examples/getfeature-wfs.html Unfortunately demo.opengeo.org seems to be down for the moment so you won't be able to see it live, but look a the source and you should be able to reproduce the same thing in your application. Basically, with the demo you can draw boxes on the map and a WFS GetFeature request is sent and the returned features are drawn as vector features on the map, looking as they were highlighted. It might be a bit too much for what you want, but it's good to see alternatives. IMHO, a WMS GetFeatureInfo request should be enough. See (instead of triggering requests on map click, make it happen on mouse move stopped): http://www.openlayers.org/dev/examples/getfeatureinfo-popup.html See also : http://www.openlayers.org/dev/examples/hover-handler.html Hope this helps, Alexandre geojoe wrote: > It turns out the layer I'm using for hover is a WMS layer and the features > property is NULL. > > How do I use hover with a WMS layer? > > Joe > > -- Alexandre Dubé Mapgears www.mapgears.com _______________________________________________ Dev mailing list [email protected] http://openlayers.org/mailman/listinfo/dev
