I add a custom Eventhandler to my views which does the picking and handling vorrect MouseEnter/MouseLeave/etc on picked objects. This EventHandler can call your WindowManager-routines handling the results. You can even search your WindowManager-node in the first frame via a nodevisitor So to use your widget-code the user has to 1) create a WidgetManager and add it to the scene, whereever he wants to 2) create a WidgetEventHandler and add it to the view, which should handle the event The WidgetEventHandler searchs for a WidgetManager when ::handle is called for the first time, and does the picking on every FRAME-event and cache the result. I don't know osgWidget for now, perhaps I am completly wrong with my suggestions, but perhaps it helps you a little bit. cheers, Stephan _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
