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.
As an example below with a type called MyStruct:
... Qt Script...
var myStruct = new MyStruct();
myStruct.x = 10;
....QML...
var myStruct;
var component = Qt.createComponent(???);
if (component.status == Component.Ready) {
myStruct = component.createObject(parent, {"x": 100, "y": 100});
}
What would ??? be?
Thanks!
