The OSG isn't event driven by default, it's frame driven. In real-time apps and games you absolutely don't want ever to be event driven, it would totally mess up getting a consistent frame rate. Instead the OSG polls for events, and this polling is done in Viewer::eventTraversal(). However, if you are using an event driven apps such as one based on Qt etc. then it'll be pushing the events to the viewer. it does sound like you are using the OSG's inbuilt event support though...
