[OpenLayers-Dev] Hover over point - Display name

[Alexandre Dube]

Hi,

Maybe you could do (untested) :


var featureInfo = new OpenLayers.Control.WMSGetFeatureInfo({
             url: 'http://spatialserver.net:8080/geoserver-nijel/wms',
	    queryVisible: true,
	    //hover: true,
	    layers: [mix_market_grossloan, mdgwatsanpipe_dwtpipe,
mdgwatsanpipe_dwtwoac, mdgwatsanpipe_sntwoac, hunger_uw, poverty_last,
countries, wo_fis, wo_partnerorgs, wo_programs_inactive, wo_programs_active,
wo_programs_featured],
             eventListeners: {
                 getfeatureinfo: function(event) {
                     // remove any popups before adding new ones
                     for (var i=0, len=map.popups.length; i<len; i++) {
                         map.removePopup(map.popups[i]);
                     }
                     map.addPopup(new OpenLayers.Popup.FramedCloud(
                         null,
                         map.getLonLatFromPixel(event.xy),
                         null,
                         event.text,
                         null,
                         true
                     ));
                 }
            }
         });


Regards,

Alexandre
