Reimplemented from osg::NodeVisitor.

virtual void osgGA::EventVisitor::apply ( osg::Node node) [inline, virtual]

During traversal each type of node calls its callbacks and its children traversed.

void osgGA::EventVisitor::removeEvent ( GUIEventAdapter event)
virtual void osgGA::EventVisitor::reset ( ) [virtual]

Method to call to reset visitor.

Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.

Reimplemented from osg::NodeVisitor.
