The key bits from example are:
kmlHoverSelectControl = new
OpenLayers.Control.SelectFeature(kmlLayers,{hover:true, highlightOnly:
true, renderIntent: "temporary" });
kmlSelectControl = new
OpenLayers.Control.SelectFeature(kmlLayers,{clickout: true});
kmlSelectControl.events.on({
"featurehighlighted": onKmlFeatureSelect,
"featureunhighlighted":
onKmlFeatureUnselect
});
map.addControl(kmlHoverSelectControl);
map.addControl(kmlSelectControl);
kmlHoverSelectControl.activate();
kmlSelectControl.activate();
kmlLayers is array of layers (in this case kml). Order matters.
HoverSelect control , the SelectControl.
With this, I highlight features as you mouse over, then select on click.
