[Solved] Cannot cast QObject subclass to QObject
-
I have a class that derives from QGraphicsWidget, and thereby from QObject.
When attempting to cast a pointer to that class to a QObject pointer, I get a compiler error in VS 2010:
error C2440: 'static_cast' : cannot convert from 'HIPASE::CTpic_GraphicsDisplayRootElementWidget *' to 'QObject *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style castMy class contains the Q_OBJECT macro, and public QGraphicsWidget is first in the list of base classes.
Any ideas?

Error was: I only forward-declared the class, didn't include the header
