IMapPieVisual.FillColor

Syntax

Description

The property is read-only.

The FillColor property returns factor hatching color parameters.

Example

Executing the example requires a form, a button named Button1 on the form, the UiMap component named UiMap1 that is a data source for the MapBox component. The map must be connected to the UiMap1 component. The VisualDataAdapter class, that creates a dynamic data source, must also be implemented. The class example is contained in the IMapVisual.DataAdapter property description.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);

Var

Map: IMap;

Layer: IMapLayer;

PieVisual: IMapPieVisual;

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 := PieVisual.Fill;

Fill.Dependent := False;

Fill.Value := GxHatchStyle.LightDownwardDiagonal;

Color := PieVisual.FillColor;

Color.Dependent := False;

Collection := Color.Values;

Collection.Count := 2;

Collection.Item(0) := GxColor.FromName("Red");

Collection.Item(1) := GxColor.FromName("Blue");

PieVisual.Radius.Value := 1.5;

End Sub Button1OnClick;

After executing the example, the pie factor is added to the Regions layer, red and blue colors are used to hatch this factor.
