laCircularSliderWidget Structure

Structure: laCircularSliderWidget_t

A slider widget draws a slider of the specified origin and radius inside the widget bounds. All coordinates are expressed in local widget space.

The color of the slider is determined by the widget scheme's 'foreground' color.

typedef struct laCircularSliderWidget_t {
  laWidget widget;
  uint32_t radius;
  uint32_t startAngle;
  uint32_t value;
  uint32_t startValue;
  uint32_t endValue;
  float degPerUnit;
