Hi Ronny,

Is it possible using the current EMBIND to pass one CPP class to another?
For example:
Here I tried constructing class Bar in the same binding declaration as Foo, and construct a Bar using Foo.
Is it possible at all, and if yes how?
Thanks
Ronny

EMSCRIPTEN_BINDINGS(Test) {
emscripten::class_<Foo>("Foo").
constructor<const char*, const char*, const char*>().
emscripten::class_<Bar>("Bar").
constructor<Foo>();
}

Sure is it possible, if you pass in the class as raw or smart pointer:

EMSCRIPTEN_BINDINGS(Test) {
    emscripten::class_<Foo>("Foo").
    constructor<const char*, const char*, const char*>();

    emscripten::class_<Bar>("Bar").

    constructor<Foo *>();
}

Watch out to terminate a class declaration properly. If I'm not wrong then you cannot bind a new class to the result of a constructor call of a previous class.
