TiPositionComponent.AddLimit
TiPositionComponent See Also
Adds a limit pair to the component.
procedure AddLimit(PointerSize, PointerMargin : Integer; DrawScaleSide : Boolean; UpperValue, LowerValue : Double; UpperPointerColor, LowerPointerColor : TColor);
Description
Call AddLimit to add a limit pair to the component. Limits can only be added
at runtime. Each limit pair has a upper and lower limit. To hide one of the
limit pointers, use the LimitShowLowerPointer or LimitShowUpperPointer properties.
The iKnob, iSlider, iLedBar, iLedSpiral components do not visually show the
limit pointers.
If the Position property exceeds the limit upper value, the
OnPositionOverLimit event will fire. If the Position property drops below the limit lower value,
the OnPositionUnderLimit event will fire.
If more than one limit pair is added and there is a possibility that the
limits pointers might overlap visually, use the PointerMargin property to offset the
pointers.
Use the DrawScaleSide property of the limit to specify if the limit is drawn
on the same side as the scale major tick labels.
Example
Delphi
iComponent.AddLimit(8, 5, False, 75, 25, clRed, clRed);
C++ Builder
iComponent->AddLimit(8, 5, False, 75, 25, clRed, clRed);
