[Users] Mouserover Events

>> thanks a lot for the tips. Just checked it out, but unfortunately I get a "TypeError: Result of expression 'this.map' [null] is not an object." in "OpenLayers.js:803" on the "sm: ....." line. Any idea what that can mean or what to do about it?

Thanks for that.

I looked around and found this, which works for clicking, but not as mouse-over:

selectControl = new OpenLayers.Control.SelectFeature(vecLayer);
map.addControl(selectControl);
selectControl.activate();
vecLayer.events.on({
	featureselected: function(e)
	{
		createPopup(e.feature);
	}
});


function createPopup(feature)
{
	var content = "<div style='font-size:.9em; width:270px;'><b>" + feature.attributes.name + "</b><hr />" + "</div>";
	popup = new GeoExt.Popup({
		title: 'Details',
		feature: feature,
		width:270,
		height:170,
		html: content,
		collapsible: true
	});
	popup.on({
		close: function() 
		{
			if(OpenLayers.Util.indexOf(vecLayer.selectedFeatures, this.feature) > -1) 
			{
				selectControl.unselect(this.feature);
			}
		}
	});
	popup.show();
}


How can I turn this then into a mouse-over popup?

Thanks for any tips!
