CMeter is an awt component bean. It displays a property's value
in the control system as a semi-circular meter object enclosed in a
rectangle. The size, bound, foreground, background and the font of the
label on the widget can be set like an awt component.
The color of the meter's needle is same as the foreground
(Fig.2) if the color mode property is set to CLRMOD_STATIC (default).
It will change from foreground color to yellow or red (Fig.1, Fig. 3,
Fig.4) depending on the value, warning and alarm limits when
CLRMOD_ALARM is used.
There are four label styles which can be selected, with a default of
LABEL_NONE (Fig.1). If LABEL_AXIS is used, the tick marks and display
range will appear on the widget (Fig. 2). In addition,
the property's value will also shown on the widget
if LABEL_VALUE is selected (Fig. 3).
The device and property name will be added when LABEL_ALL is
used (Fig.4).
