class TGSpeedo: public TGFrame, public TGWidget


TGSpeedo

TGSpeedo is a widget looking like a speedometer, with a needle,
a counter and a small odometer window.
/* */ 
                                                              //

Three thresholds are configurable, with their glowing color
A peak mark can be enabled, allowing to keep track of the highest
value displayed. The mark can be reset by right-clicking on the
widget.
Two signals are available:
OdoClicked(): when user click on the small odometer window
LedClicked(): when user click on the small led near the counter
