I connected C++ and QML via a mediator-class and have everything working in both directions but this one puzzles me.

This is how I connect the mediator-class:

// Initialize Mediator between QML and C++
QmlCppMediator m_qmlCppMediator;
QDeclarativeContext *context = viewer.rootContext();
context->setContextProperty("cppInterface", &m_qmlCppMediator);

How to fire off an ordinary Property-Animation from within C++ ?

    Ok I can answer this myself already.

    I went for an approach described here http://qt-project.org/doc/qt-4.8/qdeclarativeanimation.html

    I bind the “state” of the object which I try to animate to a Q_PROPERTY in the C++ interface.
    The different states are linked to transitions (in QML) which do the animate the object.
