TdxGaugeCustomCircularWideScale Class

The base class for wide circular scales.

Declaration

TdxGaugeCustomCircularWideScale = class(
    TdxGaugeCustomArcQuantitativeScale
)

Remarks

This class implements the functionality required by both the unbound and data-aware wide circular scales. The wide circular scales have similarities with both the arc and rectangular scales.

Like n the case of rectangular scales, the wide circular scale’s size is determined by the OptionsLayout.Width and OptionsLayout.Height values. Additionally, you can stretch the wide circular scale layout to any specified dimensions by using the OptionsLayout.Stretch property.

Like arc scales, wide circular scales have the range of valid angles, determined by the OptionsView.AngleStart and OptionsView.AngleEnd property values, corresponding to the minimum and maximum values which can be displayed by a scale.

You do not need to create instances of the TdxGaugeCustomCircularWideScale class. Use the TdxGaugeCircularWideScale and TdxGaugeDBCircularWideScale classes instead.
