Problem in compilation with custom metatype

[ada10]

I have a custom metatype declared as shown below -


class thumbnaildata : public QObject
{
Q_OBJECT

public:
thumbnaildata(); //default ctor
thumbnaildata( QPixmap aPixmap,QString aPmapFilePath ); //ctor with parameters
thumbnaildata( const thumbnaildata& other ); //mandatory copy ctor

~thumbnaildata();

void setPixmap( QPixmap aPixmap );
void setFilePath( QString aPmapFilePath );

QPixmap getPmap();
QString getPmapFilePath();

private:
QPixmap mMypixmap;
QString mPixmapFilePath;

};

Q_DECLARE_METATYPE( thumbnaildata )

When I compile this definition & use it in a model class ( compatible with QVariant ), I am getting the following error -

" Error: #145: member "thumbnaildata::staticMetaObject" may not be initialized
const QMetaObject thumbnaildata::staticMetaObject = { "

What is the issue & has anyone faced this issue before ?
