QML form in C++ class

Hi, and welcome to the Qt Dev Net! QQuickView [qt-project.org] is the C++ class for showing QML-based GUI elements. See https://blog.qt.digia.com/blog/2013/02/19/introducing-qwidgetcreatewindowcontainer/ to embed a QQuickView into QWidgets. Qt 5.3 will have a new QQuickWidget class that makes this much simpler.
