Re: [osg-users] kill and relaunch Viewer

[Rémi Dugué]

Hi, I've tried to kill and relaunch the viewers by doing this. I successfully kill the viewers, but I can't relaunch it. I have this error message : "Producer::WGLExtensions: could not make the temporary window's context active" And so, it's crash. To close, I do this : //_viewers = std::vector<osgProducer::Viewer> for(int i=0 ; i<_viewers.size() ; i++) {         _viewers[i]->setDone(true);         _viewers[i]->sync();         _viewers[i]->cleanup_frame();         _viewers[i]->sync();         _viewers[i]->unref(); } _viewers.clear(); Any idea ? Could it be a thread problem ? Thanks, Rémi. Robert Osfield a écrit : Hi Rémi, This week I checked in some fixes to the clean up of graphics context in osgProducer::Viewer and osgText, these fixed errors rather crashes, but it might help. Another important thing to do is do to a viewer.cleanup_frame() after you have exited the viewers main loop, but before you close it completely.  The osgviewer example shows how to do this. Robert.

To do it, I think I have to kill and relaunch the osgProducer::Viewer. I kill successfully the Viewer, but I can't relaunch it, because of a crash when the Viewer do its frame(). If someone have any idea...
