LNK2001: unresolved external symbol "public: static struct QMetaObject const QwtPlot::staticMetaObject"

Message 1 in thread

I have moc on the .h file, and add the generated moc_PlotCurve.cpp to my 
project, but

moc_PlotCurve.obj : error LNK2001: unresolved external symbol "public: 
static struct QMetaObject const QwtPlot::staticMetaObject" 
(?staticMetaObject@QwtPlot@@2UQMetaObject@@B)

What is "staticMetaObject"? Any idea?

Thanks,
Lingfa

Could it be that you forgot to include the Q_OBJECT macro in this 
QwtPlot class?

See QObject::metaObject() in the documentation.
