Regarding QJSEngine, some things are unclear to me.

Let's say I have a QObject-derived class.  how do I create an instance of
that class from a script ?

c++ : class Foo  : public QObject { Q_OBJECT };     js : var foo = new Foo()

How do I call a c++ function from a js script ? That use case seems not
supported at all, I'm I right ?

Those two features seems essential to me for QJSEngine to ever replace
QScriptEngine. They also are pretty basic.

I understand one will have to heavily modify the C++ code to port to
QJSEngine, but, I find the fact that the port will break the scripts...

I think QJSEngine should aim to be compatible with any script that worked
with QScriptEngine (provided the C++ code is modified accordingly)
