Visible: Boolean;
The Visible property determines indicator visibility.
Available values:
True - indicator is displayed.
False - indicator is not displayed.
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.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
Map: IMap;
MapVisual: IMapVisual;
Begin
Map := UiMap1.Map;
MapVisual := Map.FindVisual("Bar0");
If MapVisual <> Null Then
MapVisual.Visible := False;
MapVisual.RefreshData;
End If;
End Sub Button1OnClick;
After executing the example the Bar0 indicator is searched. If the indicator is found, it is hidden.
