TdxGaugeDBCircularThreeFourthScale Class

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

Declaration

TdxGaugeDBCircularThreeFourthScale = class(
    TdxGaugeCustomCircularThreeFourthScale
)

Remarks

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

Refer to the TdxGaugeCustomCircularThreeFourthScale class description for more information on the circular three-fourth scales functionality.

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

Unlike the TdxGaugeCircularThreeFourthScale class, which implements the unbound three-fourth circular scales, the TdxGaugeDBCircularThreeFourthScale class publishes the DataBinding property implemented in the TdxGaugeCustomScale class instead of the Value property implemented in the TdxGaugeQuantitativeScale class.
