The effect is equivalent to using \c QML_FOREIGN with custom structs in the QML library to expose the types. + +\note In order to implement custom behavior, such as exposing an existing +singleton instance with its own life cycle to QML, you should add custom types +to your QML library (mylib_declarative in the above example). In turn, you +should omit the \l QML_ELEMENT and similar macros from the original C++ classes +so that qt_generate_foreign_qml_types() does not generate more QML integration +structs for them.
