QMetaType::metaObjectForType returns NULL

[VeNToR]

Hi;

QMetaType::metaObjectForType(QMetaType::type("IChRSMSession*")) returns NULL.

IChRSMSession is interface that defined in DLL/Library as above;

class IChRSMSession
{
Q_GADGET
..
};

QT_BEGIN_NAMESPACE

#define IChRSMSession_IID "com.motiontrue.plugins.IChRSMSession"

Q_DECLARE_INTERFACE(IChRSMSession, IChRSMSession_IID)

QT_END_NAMESPACE

Q_DECLARE_METATYPE(IChRSMSession*)

@VeNToR Did you register it using http://doc.qt.io/qt-5/qmetatype.html#qRegisterMetaType ?

[VeNToR]

@jsulm Yes, I did. qRegisterMetaType<IChRSMSession*>();

Hi,

Because there are none. A Q_GADGET is not a QObject based class. You only have the staticMetaObject like describe in the macro documentation.

As @SGaist said there's no such thing, but to pile on IChRSMSession* isn't even a gadget it's simply a pointer.

[VeNToR]

Thanks your returns. I wrote virtual function to get QMetaObject of the up class of interface class.

[SGaist]

How did you do that ?
