14// TGSpeedo //
15// //
16// TGSpeedo is a widget looking like a speedometer, with a needle, //
17// a counter and a small odometer window. //
18// //

23//End_Html //
24// //
25// Three thresholds are configurable, with their glowing color //
26// A peak mark can be enabled, allowing to keep track of the highest //
27// value displayed. The mark can be reset by right-clicking on the //
28// widget. //
29// Two signals are available: //
30// OdoClicked(): when user click on the small odometer window //
31// LedClicked(): when user click on the small led near the counter //
32// //
