If you want v8 to know about the object, the native ctor must tell it. Or you can... > Is it possible to do that?

Any ideas? > NewInstance() works for me. Here's an example of how i'm using it: http://code.google.com/p/v8-juice/source/browse/convert/include/cvv8/ClassCreator.hpp?r=2173#894 The CastFromJS() call there essentially needs to be replaced with your extract-native-from-JS-Object routine. If you want to be able to destroy such object from C++ code (don't use delete - it will leave the v8 bits pointing at dead objects), there's an example of that here: http://code.google.com/p/v8-juice/source/browse/convert/include/cvv8/ClassCreator.hpp?r=2173#971 i hope that helps. -- ----- stephan beal http://wanderinghorse.net/home/stephan/ http://gplus.to/sgbeal -- v8-users mailing list [email protected] http://groups.google.com/group/v8-users
