Hi Roni,
You can't remove an object while its being operated on, so you need to
change you code so that the event handler sets an operation that you
main loops does at a safe time. You'll need to stop and start
threading as well to avoid threads still using the view when you
remove it, so do something like:
while(!viewer.done())
{
viewer.advance();
viewer.eventTraversal();
viewer.updateTraversal();
if (needToDoSpecialViewerOperation)
{
viewer.stopThreading();
// do my special operations...
viewer.startThreading();
}
viewer.renderingTraversals();
}
