Have a look at the osgpick example as it has an example of code
casting to a View from the GUIActionHandler :
bool PickHandler::handle(const osgGA::GUIEventAdapter&
ea,osgGA::GUIActionAdapter& aa)
{
switch(ea.getEventType())
{
case(osgGA::GUIEventAdapter::PUSH):
{
osgViewer::View* view = dynamic_cast<osgViewer::View*>(&aa);
if (view) pick(view,ea);
return false;
}
In your case casting to an osg::View* would be sufficient as it has an
osg::FrameStamp. osgViewer::View subclasses from osg:View so the cast
should resolve this fine.
