CapLength: Double;
The CapLength property determines arrow pointer length. The pointer length is determined as a part of the length of line segment between the anchor points of the connected territories. The allowed values lie in the range [0.0; 1.0].
NOTE. The property operates if the IMapArrow.Shape property is set to MapArrowShape.Simple or MapArrowShap.Tailed.
Executing the example requires a form with a button named Button1, the UiMap component named UiMap1 and the MapBox component. The map must be connected to the UiMap1 component.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
Maps: IMap;
Layer: IMapLayer;
Arrows: IMapLayerArrows;
Arrow: IMapArrow;
Begin
Maps := UiMap1.Map;
Layer := Maps.Layers.FindByName("Regions");
Arrows := Layer.Arrows;
Arrows.CreateByIDs(98, 46);
Arrow := Arrows.Item(0);
Arrow.Shape:=MapArrowShape.Tailed;
Arrow.CapLength := 0.1;
End Sub Button1OnClick;
After executing the example the arrow with the specified pointer length is created:
