TopoBase: IMapTopobase;
The TopoBase property determines a map topobase.
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. The map must be connected to the UiMap1 component.
The example is a handler of the OnClick event for the Button1 component.
Add links to the ExtCtrls, Forms, Map, and Metabase system assemblies.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
MetaBase: IMetabase;
TopoBase: IMapTopobase;
Map: IMap;
Begin
MetaBase := MetabaseClass.Active;
TopoBase := MetaBase.ItemById("MAP_RF").Bind As IMapTopobase;
Map := UiMap1.Map;
Map.Topobase := TopoBase;
End Sub Button1OnClick;
After executing the example the MAP_RF map is loaded to the MapBox component.
