IMapFillScale.Fill

Syntax

Fill(Index: Integer; Impact: MapScaleSettingImpact): GxHatchStyle;

Parameters

Index - scale tick mark index.

Impact - determines the position relative to the scale tick mark value.

Description

The Fill property determines hatching type for the specified scale tick mark value.

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;

AreaVisual: IMapAreaVisual;

Fill: IMapVisualFillProperty;

Color: IMapVisualColorProperty;

Scale: IMapFillScale;

Begin

Map := UiMap1.Map;

Layer := Map.Layers.FindByName("Regions");

AreaVisual := Layer.Visuals.AddAreaVisual;

AreaVisual.DataAdapter := New VisualDataAdapter.Create As IMapDynamicDataAdapter;

Fill := AreaVisual.Fill;

Fill.DataAdapter := AreaVisual.DataAdapter;

Scale := Fill.Scale;

Scale.Count := 1;

Scale.AutoCalculable := True;

Scale.Fill(0, MapScaleSettingImpact.Greater) := GxHatchStyle.Cross;

Scale.Fill(0, MapScaleSettingImpact.Less) := GxHatchStyle.DarkUpwardDiagonal;

Fill.Dependent := True;

Color := AreaVisual.FillColor;

Color.Values.Count := 1;

Color.Values.Item(0) := GxColor.FromName("Blue");

Map.Refresh;

End Sub Button1OnClick;

After executing the example the map indicator, which hatching type is scale determined, is added to the Regions layer:
