+ * \class VUMeter
+ * \brief A widget holding level indicators, 'over' LEDs, and a scale
+ *
+ * The VUMeter class is a widget that holds one or more level indicators
(VUMeterLevel),
+ * one or more 'over' LEDs (VUMeterOverLed), and one scale (VUMeterRuler).
Usually one
+ * VUMeter per track is created, which contains one level indicator and 'over'
LED per
+ * audio channel (2 for stereo) and one scale. The name of the track is shown
below
+ * the level indicators.
+ *
+ * The scale is hidden automatically if the width of the widget becomes too
narrow.
+ *
+ * All VUMeter related classes are designed to be arranged in a QGridLayout so
as to
+ * resize correctly.

- *
- * The VUMeter class is a widget that holds one or more level indicators
(VUMeterLevel),
- * one or more 'over' LEDs (VUMeterOverLed), and one scale (VUMeterRuler).
Usually one
- * VUMeter per track is created, which contains one level indicator and 'over'
LED per
- * audio channel (2 for stereo) and one scale. The name of the track is shown
below
- * the level indicators.
- *
- * The scale is hidden automatically if the width of the widget becomes too
narrow.
- *
- * All VUMeter related classes are designed to be arranged in a QGridLayout so
as to
- * resize correctly.
