Hi all,<br><br>This is a question I asked some times myself when using some OpenLayers features, and it raised again after reading Bart's post in GeoExt devs list (<a href="http://www.geoext.org/pipermail/dev/2010-November/000893.html">http://www.geoext.org/pipermail/dev/2010-November/000893.html</a>). There are some classes that trigger some event (of some types) when some things occur (e.g. the SelectFeature control triggers, for instance, <b>featurehighlighted</b> event). Other (or same) classes provide the user with functions he can write and they will be executed also when some things occur (e.g. the same SelectFeature control, the <b>onSelect</b> function). So far I didn't find a duplicate use case, but I understand those are 2 different ways to do the same thing (maybe the order your code is executed is determined in a different way). Are they almost the same or is there a way preferred? Maybe, if that's the case, this could be reconsidered in OpenLayers 3<br>
