TdxGaugeDBCircularHalfScale Class

A data-aware half-circular scale created within the Gauge Control.

#Declaration

Delphi
TdxGaugeDBCircularHalfScale = class(
    TdxGaugeCustomCircularHalfScale
)

#Remarks

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.
