Hi Erland, Follow the various subclasses of osg::Drawable to see what is required, I'd consider subclassing osg::Drawable an advanced topic so be prepared to invest time in reviewing this various implementations and how they related to the include/osg/Drawable.
As for display listing - if you do need this then call setUseDisplayList(false) in your constructor, or better still if display lists are never suitable call setSupportsDisplayList(false); Robert.
