Pen: IGxPen;
The Pen property determines arrow line and arrow pointer parameters.
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;
Pen: IGxPen;
Begin
Maps := UiMap1.Map;
Layer := Map.Layers.FindByName("Regions");
Arrows := Layer.Arrows;
Arrows.CreateByIDs(56, 46);
Arrow := Arrows.Item(0);
Pen := New GxPen.CreateSolid(GxColor.FromName("Red"), 2);
Pen.EndCap := GxLineCap.RoundAnchor;
Arrow.Pen := Pen;
End Sub Button1OnClick;
After executing the example the arrow with the specified arrow parameters and the arrow pointer parameters is created:
