Problème avec QObject::connect()
Bonjour,
Je tente d'écrire un pavé numérique en c++/QML. Je sèche sur l'erreur suivante :
Code:

| ..\paveNum\main.cpp: In function 'int qMain(int, char**)':
..\paveNum\main.cpp:17: error: no matching function for call to 'QObject::connect(QGraphicsObject**, const char*, MyClass**, const char*)'

c:\QtSDK\Simulator\Qt\mingw\include/QtCore/qobject.h:313: note: bool QObject::connect(const QObject*, const char*, const char*, Qt::ConnectionType) const |
Quelqu'un aurait-il une idée d'où elle pourrait provenir ?!
