In C++ QCoreApplication::instance returns a QCoreApplication pointer and QApplication::instance returns a QApplication pointer. In Python both return the correct type because the bindings always try to discover the real type of a C++ variable, i.e. app = QApplication([]) type(app) == type(QCoreApplication.instance()) # True > > Farsmo > > _______________________________________________ > PySide mailing list > PySide@lists.openbossa.org > http://lists.openbossa.org/listinfo/pyside -- Hugo Parente Lima INdT - Instituto Nokia de Tecnologia
