IMapVisualFillProperty.Value

Syntax

Value: GxHatchStyle;

Description

The Value property determines an indicator hatching type.

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. A map should be connected to the UiMap1 component. The VisualDataAdapter class that creates a dynamic data source should also be implemented. The class example is contained in the IMapVisual.DataAdapter property description.

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

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Map: IMap;
    Layer: IMapLayer;
    BarVisual: IMapBarVisual;
    Fill: IMapVisualFillProperty;
    Color: IMapVisualColorProperty;
    Collection: IMapColorCollection;
Begin
    Map := UiMap1.Map;
    Layer := Map.Layers.FindByName("Regions");
    BarVisual := Layer.Visuals.AddBarVisual;
    BarVisual.DataAdapter := New VisualDataAdapter.Create As IMapDynamicDataAdapter;
    Fill := BarVisual.Fill;
    Fill.Dependent := False;
    Fill.Value := GxHatchStyle.DarkUpwardDiagonal;
    Color := BarVisual.FillColor;
    Collection := Color.Values;
    Collection.Item(0) := GxColor.FromName("Red");
    BarVisual.Width.Value := 1;
End Sub Button1OnClick;

After executing the example the map indicator, which is hatched in red, is added to the Regions layer:
