TdxGaugeDBCircularQuarterLeftScale Class

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

Declaration

TdxGaugeDBCircularQuarterLeftScale = class(
    TdxGaugeCustomCircularQuarterLeftScale
)

Remarks

Circular quarter-left scales are designed to imitate analog measuring, such as voltmeters, galvanometers, multimeters, etc.

Refer to the TdxGaugeCustomCircularQuarterLeftScale class description for more information on the quarter-left circular scales functionality.

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

Unlike the TdxGaugeCircularQuarterLeftScale class, which implements the unbound circular quarter-left scales, the TdxGaugeDBCircularQuarterLeftScale class publishes the DataBinding property implemented in the TdxGaugeCustomScale class instead of the Value property implemented in the TdxGaugeQuantitativeScale class.
