[OpenLayers-Users] Tooltip for vectorlayer icons

[Andreas Hocevar]

If you download the latest OpenLayers (master from
http://github.com/openlayers/openlayers, you can simply give your
symbolizer a 'graphic' property. If your feature attributes have e.g. a
'tooltip' attribute, the value for the 'graphic' property would be
'${tooltip}'.

See http://openlayers.org/dev/examples/vector-features.html for an example.
