- 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.
