IMapVisualNumericProperty.Value

Syntax

Value: Double;

Description

The Value property determines a parameter 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;

BarVisual: IMapBarVisual;

Height: IMapVisualNumericProperty;

Begin

Map := UiMap1.Map;

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

BarVisual := Layer.Visuals.AddBarVisual;

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

Height := BarVisual.Height;

Height.Dependent := False;

Height.Value := 5;

End Sub Button1OnClick;

After executing the example the bar indicator, which maximum height is to be set, is added to the Regions layer.
