    Pen: IGxPen;
Begin
    Maps := UiMap1.Map;
    Layer := Maps.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;
