vcl-dxgaugedbscale-206a0d6a.md
A data-aware half-circular scale created within the Gauge Control.
TdxGaugeDBCircularHalfScale = class(
TdxGaugeCustomCircularHalfScale
)
Half-circular scales are designed to imitate analog measuring instruments, such as voltmeters, galvanometers, multimeters, etc.
Refer to the TdxGaugeCustomCircularHalfScale class description for more information on the circular-half scales functionality.
The TdxGaugeDBCircularHalfScale class extends its ancestor class with the Value property that allows you to read the value currently displayed by a half-circular scale. For information on published members that are responsible for both the appearance and functionality of half-circular scales, refer to the TdxGaugeCustomCircularHalfScale class description.
Unlike the TdxGaugeCircularHalfScale class, which implements the unbound half-circular scales, the TdxGaugeDBCircularHalfScale class publishes the DataBinding property implemented in the TdxGaugeCustomScale class instead of the Value property implemented in the TdxGaugeQuantitativeScale class.
