There isn't a dragger callback for updating an osg::ClipNode, the closest is the DraggerVolumeTileCallback found in the examples/osgvolume/osgvolume.cpp example. This example uses the dragger callback to update the dimensions of the volume that is to be rendered allow you to home in small regions of the total volume - it's the volume rendering equivalent to what you want to do. My guess is that you can probably learn from how I implemented this callback for hooking it up to the clip planes in a ClipNode.
