[since 6.1] QQmlListReference:: QQmlListReference (const QVariant & variant , QQmlEngine * engine )

This function is deprecated. We strongly advise against using it in new code.

Use the constructors without QQmlEngine argument instead.

Constructs a QQmlListReference from a QVariant variant 包含 QQmlListProperty 。若 variant does not contain a list property, an invalid QQmlListReference is created. If the object owning the list property is destroyed after the reference is constructed, it will automatically become invalid. That is, it is safe to hold QQmlListReference instances even after the object is deleted.

The engine is unused.
