Hi James, You have complete control of the event order if you want it, you just need to subclass from osgViewer:Viewer/CompositeViewer:eventTraversal() and do what you want, or just doing your own implementation of the frame loop.
The best illustration of what the osgViewer is doing w.r.t event order is to read the osgViewer::Viewer::eventTraversal() implementation in src/osgViewer/Viewer.cpp. Robert.
