Declaration

delphi

TdxRangeControlPredefinedDateTimeScale = class(
    TdxRangeControlDateTimeScale
)

Remarks

This class extends its ancestor with the DisplayFormat property that allows you to apply a specific formatting to tickmark labels displayed by the scale. For descriptions of the public properties and methods related to the core date/time scale functionality, refer to the TdxRangeControlDateTimeScale class description.

A TdxRangeControlPredefinedDateTimeScale object is referenced by:

The Day, Hour, Minute, Month, Quarter, Week, and Year properties provided by the TdxRangeControlDateTimeScales class;
The TdxRangeControlDateTimeScales class’ GetScale, RegisterScale, and UnregisterScale methods.

Since all predefined date/time scales are referenced as a TdxRangeControlDateTimeScale object, you need to cast it to the TdxRangeControlPredefinedDateTimeScale type in order to access all of its members.
