TdxRangeControlCustomClientProperties.GetMinSelectedInterval Method

Returns the minimal selectable range for the data range selection and visualization model.

#Declaration

Delphi
function GetMinSelectedInterval: Variant; virtual;

#Returns

Type
Variant

#Remarks

Normally, this function supports the internal infrastructure and is not intended to be used directly from your code. The GetMinSelectedInterval function is called internally by the range control to identify the actual minimal selectable range (in range value type values or measurement units of the currently active or visible scale) when a data range is selected.

The GetMinSelectedInterval function returns 0, indicating that the base data range model allows you to:

  • Select a data range corresponding to a fraction of the current measurement unit;

  • Clear the data range selection, leaving an “empty” selected range.

Specific data range models implemented by the TdxRangeControlCustomClientProperties class descendants, may impose a limitation on the minimal selectable data range by overriding this function.
