How am I supposed to use the QVariant(int typeOrUserType, const void*
copy) constructor from Python? The documentation refers to
sip.voidptr, which I know nothing about, and  to use qVariantFromValue
which isn't defined.

I need to store objects of a custom class in QVariants, with a certain
type code (QVariant::Type). The reason I need to do this is that
QItemEditorFactory is parameterized on QVariant::Type.
