IMapLegend.ColumnCount

Syntax

ColumnCount: Integer;

Description

The ColumnCount property determines the number of legend columns.

Comments

If the property value is zero, the number of columns is set automatically.

Example

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 UiMap1 component must have a connected map that contains a map indicator only.

The example is a handler of the OnClick event for the Button1 component.

Add links to the ExtCtrls, Forms, and Map system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Map: IMap;
    Layer: IMapLayer;
    Legend: IMapLegend;
Begin
    Map := UiMap1.Map;
    Legend := New DxMapLegend.Create As IMapLegend;
    Map.View.Legend := Legend;
    Legend.Visible := True;
    Legend.BeginUpdate;
    Layer := Map.Layers.FindByName("Regions");
    Legend.Visual := Layer.Visuals.Item(0);
    Legend.ColumnCount := 3;
    Legend.EndUpdate;
End Sub Button1OnClick;

After executing the example the legend that contains no more than three columns is displayed for the map indicator:
