IMapLayerVisuals.Clear

Syntax

Clear;

Description

The Clear method clears a indicators collection.

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 UiMap1 component should be linked to a map containing indicators on the Regions layer.

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

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

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Map: IMap;
    Layer: IMapLayer;
    Visuals: IMapLayerVisuals;
Begin
    Map := UiMap1.Map;
    Layer := Map.Layers.FindByName("Regions");
    Visuals := Layer.Visuals;
    Visuals.Clear;
End Sub Button1OnClick;

After executing the example all the indicators are removed from the Regions layer.
