You'll need to get the osgGA::EventQueue which you are pushing the user
events to and then traverse through the events in the queue and check each
one.

The application can have multiple EventQueue, one per osgViewer::Window and
one osgGA::Device, and one per osgViewer::View.  The viewer EventTraversal
will collate these and then pass them on to the event handlers and do the
event traversal.

I know nothing about your application so really can't provide any specific
advice.
