According to the documentation the SwipeView shall support the function getFlickable. Looking into the c++ source code, it is also existing. But it is missing in the SwipeView.qml which is the auto genereated interface file for qml. Looking into swipeviewtemplate (QtMCUs\1.8.0\include\qul\private\controls) one can see that the getFlickable method is not marked to be used in QML and therefore the auto generator does not includes it in qml interface. But without that access it is imposible on QML side to check if the SwipeView is currently moving.
