Not on values. That is, it indicates whether there is a conversion path from origin type to the destination type, not that the conversion will succeed when attempted. For example: QObject *o = new QAbstractItemModel; QVariant variant = QVariant::fromValue(o); qDebug() << variant.canConvert<QAbstractItemModel*>(); This conversion *will* succeed for this particular value of a QObject*, so canConvert() must return true for conversions between QObject* and QAbstractItemModel*, despite not all such conversions being possible. This is also done in preparation of changes being done to the conversion routines that may cause some FP->integer conversions to fail depending on the value of the FP.
