TdxGaugeDBCircularScale Class

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

Declaration

TdxGaugeDBCircularScale = class(
    TdxGaugeCustomCircularScale
)

Remarks

Circular scales are designed to imitate speedometers, tachometers, clocks, stopwatches and other similar measurement instruments.

Refer to the TdxGaugeCustomCircularScale class description for more information on the circular scales functionality.

The TdxGaugeDBCircularScale 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 circular scales, refer to the TdxGaugeCustomCircularScale class description.

Unlike the TdxGaugeCircularScale class, which implements the unbound circular scales, the TdxGaugeDBCircularScale class publishes the DataBinding property implemented in the TdxGaugeCustomScale class instead of the Value property implemented in the TdxGaugeQuantitativeScale class.
