Hi guys,

Exact error was :

\CanScene.cpp(17) : error C2664: 'bool QObject::connect(const QObject *,const char *,const QObject *,const char *,Qt::ConnectionType)' : cannot convert parameter 1 from 'QGraphicsItem *' to 'const QObject *'
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

Regards,
Steve
