The destructor is fine, what is up is that with some set ups such as GraphicsWindowEmbedded, or certain other combinations of windowing destruction order the makeCurrent() fails and the subsequent flush of OpenGL objects in the scene graph to for the OSG to clean up properly fails as you can't call OpenGL without a valid graphics context obviously. The fix is to do a check in the GraphicsContext::close() method to see if the makeCurrent() worked, i.e. returned true, and only do the flush of OpenGL objects if this sucedded. The fix is checked into OSG SVN/OSG2.3.0. So... OSG quality does continue to improve ;-) Robert. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
