How are these method of XYSeries QML Type exported to qml without Q_INVOKABLE macro in the class QXYSeries?

[Crawl.W]

I have viewed chartsqml2_plugin.cpp and qxyseries.h before, but I could not find Q_INVOKABLE macro before function declaration. Is there any way to export the function from c++ to qml?

There can be a quick wrapper around this class. Also every slot can be invoked from QML like it is marked as invokable.

Can you use XYSeries for example? I couldn't find a quick wrapper.
And will the quick wrapper export all public method of c++ class? However, there are no conversion for some type.

I just noticed that XYSeries is a uncreatable type, its derived object's Q_INVOKABLE method invoke member method of DeclarativeXySeries class, and DeclarativeXySeries is a shadow class about XYSeries. Such as LineSeries is imported from DeclarativeLineSeries.
