Detailed Description

A C++ type that needs all its properties before it can do its work inherits QQmlParserStatus as well as QObject: classBegin() is called when the object has been made, before its properties are set, and componentComplete() when its component is complete, all bindings set.

class Loader : public QObject, public QQmlParserStatus {
    Q_OBJECT
    Q_INTERFACES(QQmlParserStatus)
    ...
    void classBegin() override {}
    void componentComplete() override { load(m_source); }
};

Differences from Qt

None; Q_INTERFACES is not needed in Nt, which finds the interface with dynamic_cast.
