    Question Passing QQuickGradient, QQmlComponent and LabelStyle values from QML to C++;

    Hello;

    QML side: can I pass (by value) QQuickGradient, QQmlComponent and LabelStyle from QML to C++ as QVariant type?
    C++ side: can I store them in say a QVarianMap?
    QML side: can I then retrieve (from C++) the store values as QVariant?

    void myClass::set(const QVariant& value, const QString& name) { // QINVOKABLE method called from QML side
    {
    // insert in QVariant map with name as a key
    }

    QVariant myClass::get(const QString& name) { // QINVOKABLE method called from QML side

    // retrieved from the QVariant map
    }

    Any thoughts?

    Thanks;

    Mut

    QQmlComponent exists as a public type, but all of them are QObject derived, so a QObject* should do.

    Obviously keep in mind that these pointers are owned by the QQmlEngine which can delete them at any given time.

    Cheers,

    Thank you for the reply.
    Do you mean that my parameter can be pointer to QObject (QObject*) instead of QVariant?
