I am using NDrawingDiagram to create different shapes based on an external database. I am able to programmatically place a custom shape on to the drawingview without any issues. I am not currently using a library for these custom shapes and I would really prefer to avoid this option. All of my custom shapes are currently NGroups. I do not want users to be able to place Ellipses onto the drawingview and have overridden the NEnableCreateEllipseToolCommand with my own Command. I am wondering if this is the right way to go about this or should I create my own custom Tool with a corresponding Enable command?

Here is my current code.


using System.Linq;
using System.Text;
using Nevron;
using Nevron.Diagram.WinForm.Commands;
using Nevron.UI;

namespace Elixir.App.FormatDesigner
{
public class EnableCreateBarcodeCommand : NEnableCreateEllipseToolCommand
{

public EnableCreateBarcodeCommand()
: base()
{
base.Text = "Barcode Tool";
base.TooltipText = "Barcode Tool";
}

public override void Execute()
{
base.Execute();
}

}
}
