TdxGaugeDBCircularWideScale Class

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

Declaration

TdxGaugeDBCircularWideScale = class(
    TdxGaugeCustomCircularWideScale
)

Remarks

Like half- and quarter-circular scales, the wide circular scales are designed to imitate analog measuring instruments, such as voltmeters, galvanometers, multimeters, etc.

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

The TdxGaugeDBCircularWideScale class extends its ancestor class with the Value property that allows you to read the value currently displayed by a wide circular scale. For information on published members that are responsible for both the appearance and functionality of wide circular scales, refer to the TdxGaugeCustomCircularWideScale class description.

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