VkVuMeter(3x)VkVuMeter(3x)CLASS DESCRIPTIONVkVuMeter presents a vertical set of segments as a meter display,
similar to that used by hi-fi audio displays. Its value ranges from
0 to 110, with 0 showing the most segments and 110 showing the
least. A peak value is displayed separately, as an entire block or
as a line.
FUNCTION DESCRIPTIONSVkVuMeter()
VkVuMeter(char* name, Widget parent)
virtual void ~VkVuMeter(void);
VkVuMeter creates a component using the name and parent parameters.
setValue()
void setValue(int value, int peak);
This function changes the currently display value. A separate peak
value will also be displayed. It is expected that peak <= value.
