Link to original bug (#613435)
Description
Some applications, particularly some multimedia softwares, as amsynth(http://amsynthe.sourceforge.net/amSynth/ ) or gmorgan ( http://gmorgan.sf.net/ ), use rotating knobbers, like QDial, which is used in mixxx (http://mixxx.org) or QSynth (http://qsynth.sourceforge.net/qsynth-index.html ). Why don't you create that kind of class, avoiding to reinvent the wheel each time a new software appear ?
