IMapVisualNumericProperty.Dependent

Syntax

Dependent: Boolean;

Description

The Dependent property determines whether a parameter scale is used.

Comments

Available values:

True. The scale that is determined by the IMapVisualNumericProperty.Scale property is used, the IMapVisualNumericProperty.Value property value is ignored.
False. The value that is determined by the IMapVisualNumericProperty.Value property is used, the IMapVisualNumericProperty.Scale property value is ignored.

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.
