IMapLayer.Arrows

Syntax

Arrows: IMapLayerArrows;

Description

The Arrows property returns the collection of map layer arrows.

Example

Executing the example requires a form with the following components: the Button component named Button1, the MapBox component named MapBox1, and the UiMap component named UiMap1. UiMap1 is a data source for MapBox1. The map must be connected to the UiMap1 component.

The example is a handler of the OnClick event for the Button1 component.

Add links to the ExtCtrls, Forms, and Map system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Map: IMap;
    Layer: IMapLayer;
    i: Integer;
    s: String;
Begin
    Map := UiMap1.Map;
    Layer := Map.Layers.FindByName("Regions");
    s := Layer.Description;
    Debug.WriteLine("Description of the Regions layer " + s);
    i := Layer.Id;
    Debug.WriteLine("Identifier of the Regions layer " + i.ToString);
    i := Layer.Shapes.Count;
    Debug.WriteLine("Number of areas, of which the Regions layer consists " + i.ToString);
    i := Layer.Arrows.Count;
    Debug.WriteLine("Number of arrows on the Regions layer " + i.ToString);
    s := Layer.AttributeNames.Item(0);
    Debug.WriteLine("Name of the first attribute of the Regions layer " + s);
    i := Layer.ChildLayers.Count;
    Debug.WriteLine("Number of child layers for the Regions layer " + i.ToString);
    S := Layer.Owner.Name;
    Debug.WriteLine("Name of parent layer for the Regions layer " + s);
    i := Layer.Visuals.Count;
    Debug.WriteLine("Number of indicators on the Regions layer " + i.ToString);
End Sub Button1OnClick;

After executing the example the console displays information about the Regions layer:
