\subsection{Detailed Description}
Inventor-\/like wheel widget. 

The wheel widget is typically turned with the mouse. Dragging the wheel from one side of the widget to the other will changed the angle by {\itshape pi} (=180 deg()). Use gear() to make the angle change faster or slower.

The user can manually {\itshape shift} the gear by double clicking the left (top) or right (bottom) part of the widget. gear() doubles or halves, cf gear\+Up(), gear\+Down(). The current gear setting is displayed by {\itshape red} (faster) or {\itshape blue} (slower) bars on the left/right (bottom/top) side of the widget.
