TdxGaugeDBLinearScale Class

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

Declaration

TdxGaugeDBLinearScale = class(
    TdxGaugeCustomLinearScale
)

Remarks

A data-aware linear scale is designed to imitate thermometer-like measuring instruments. Linear scales can be horizontal or vertical, and support all predefined styles.

Refer to the TdxGaugeCustomLinearScale class description for more information on the linear scales functionality.

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

Unlike the TdxGaugeLinearScale class, which implements the unbound linear scales, the TdxGaugeDBLinearScale class publishes the DataBinding property implemented in the TdxGaugeCustomScale class instead of the Value property implemented in the TdxGaugeQuantitativeScale class.
