JavascriptCallback (object)

You can pass a callback function from Javascript to Python, when you do that, what you get in Python is a JavascriptCallback object that you can use to call javascript function back.

If you call the javascript callback and it fails, instead of js exception what you get is a python exception that exits the application by default (see sys.excepthook in examples).

See also JavascriptBindings.

See also Issue #11 (Throw JS / Python exceptions according to execution context).
