TdxGaugeCustomCircularHalfScale Class
The base class for half-circular and quarter-circular scales.
Declaration
TdxGaugeCustomCircularHalfScale = class(
TdxGaugeArcQuantitativeScale
)Remarks
This class implements the functionality required by both the half-circular and quarter-circular scales. The half-circular scales differ mainly from circular scales by the limitations applied to the starting and ending angles of the range of displayed values.
Despite the similar functionality, the quarter-circular, three-fourth circular, and half-circular scales differ mainly by the valid range of the OptionsView.AngleStart and OptionsView.AngleEnd values, corresponding to the minimum and maximum values which can be displayed by a scale.
You do not need to create instances of the TdxGaugeCustomCircularHalfScale class. Use its descendants that implement both the unbound and data-aware classes:
