[default, deprecated] QQmlListProperty:: QQmlListProperty ( QObject * object , QList < T *> & list )

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

Convenience constructor for making a QQmlListProperty value from an existing QList list 。 object owning the list and the list itself must be provided and kept alive as long as you are holding a QQmlListProperty referring to them.

This constructor synthesizes the removeLast() and replace() methods introduced in Qt 5.15, using count(), at(), clear(), and append(). This is slow. If you intend to manipulate the list beyond clearing it, you should explicitly provide these methods.
