[OpenLayers-Users] Labels/Tooltips on mouse over a Vector layer

[Sajeer...]

Ok, then replace

selectControl = *new* OpenLayers.Control.SelectFeature(kmlLayer,

{hover: *true*,onSelect: onFeatureSelect, onUnselect: onFeatureUnselect});

with

selectControl = *new* OpenLayers.Control.SelectFeature(kmlLayer,

{ clickout: true, hover: false });



and add this too

kmlLayer.events.on({

"featureselected": function(e) {

onFeatureSelect(e.feature);

},

"featureunselected": function(e) {

onFeatureUnselect(e.feature);

}

});



Regards

Sajeer
