- For Python/Shiboken types not known to Qt that requires wrapping around a QVariant, we use the PyObjectWrapper type. This patch registers a toInt() QMetaType converter for PyObjectWrapper, which enables automatic conversion to int for a QVariant(PyObjectWrapper) within C++ i.e. QVariant(PyObjectWrapper).toInt() will work - This means that cases like QAbstractItemModel::data() that calls QtPrivate::legacyEnumValueFromModelData(const QVariant &data) would work without explicit conversion from QVariant(PyObjectWrapper) to QVariant(int). But for cases like QMetaProperty::write() explcit handling is still required. - This would also work for cases where the QVariant(PyObjectWrapper) is simply channeled from Python to C++, and from C++ back to Python without performing any operations on it. - Incase, the wrapped object is not a PyEnum/ShibokenEnum object, then toInt() would return a -1.
