    Hello,

    I want to create, store and delete Qml-Objects (like http://doc.qt.io/qt-5/qtqml-javascript-dynamicobjectcreation.html).

    My Question ist:
    I pass and store the created Object in C++. Can I delete the passed object without memoryleak or do I have to delete the object in Qml (like in the tutorial)?

      I think you can delete in C++, especially if you have created the object in C++, too.

          Check with valgrind to be sure, but I think it is OK (use deleteLater() or destroy() method: link).
