It does use a config test for now, just to make it clearer. The Mac backend currently requires widgets, but most of the others should work without it (just not supporting QVideoWidget/WindowControl). The QVideoDeviceControl interface was modified to remove the QIcon usage - it was never implemented. Unfortunately even the QML examples need widgets for the wrapper application, and will need to be ported to QtGui based wrapper.
