You need to convert the classes to QDeclarativeItem subclasses. After doing this, I think the only issue you will have is to find the proper parent for your items. Things don't turn up in QML unless they have a parent. There is a good amount of information on this page: http://qt-project.org/doc/qt-4.8/qtbinding.html Adding items dynamically using C++ is still awkward. But it is possible, I have done it one several customer projects now. It's funny that QML is always described as a language for dynamic UIs, when in fact it's specifically designed for static UIs where the items can move.
