CLASS DESCRIPTION
	  VkVuMeter 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 DESCRIPTIONS    [Toc]    [Back]

   VkVuMeter()
	   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.
