> I saw this thread, but it did not seem to offer a clear detail other than to use QJSEngine and QJSValue directly.  Specifically I use qScriptRegisterMetaType very heavy to add custom types.  I know if I am using QML I can use qmlRegisterType<T>(uri, 1, 0, "T") but it only makes the type available via the declarative components.  It also requires the object be a QObject which means sharing pointers.  There is also a problem inside of the Javascript.  It is very cumbersome to dynamically create these types.  I understand I am fighting QML, but my design is not as declarative as it is creating objects that can be passed back into C++.   I may be missing something though.

If MyStruct is just a JS object, then just use JS. function MyStruct(){ return {"x": 100, "y": 100}; }; var myStruct = new MyStruct();
You only need createObject when you are creating an object defined in C++ or dynamic object from QML.
