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();
}

}
}

Here it is: (You can convert these code to inherit from NEllipseShape)


public class NFaiencePolygonShape: NPolygonShape
{
#region CTors

public NFaiencePolygonShape() { }

public NFaiencePolygonShape(NPointF[] points): base(points)
{

}

public NFaiencePolygonShape(NPolygonPath primitive): base(primitive)
{

}

#endregion

#region Properties

private string _Key = Guid.NewGuid().ToString();
public string Key { get { return _Key; } }

public int XPFaienceId { get; set; }
public FaienceDisplayMode FaienceDisplayMode { get; set; }
public bool AutoDecorate { get; set; }
public float DerzWidth { get; set; }
public float OffsetX { get; set; }
public float OffsetY { get; set; }
public float RotationAngle { get; set; }

public Color DerzColor { get; set; }
public float Tracker { get; set; }
public int TamFayansCount { get; set; }
public int BrokenFayansCount { get; set; }

#endregion
}





public class NCreateFaiencePolygonTool : NCreatePolygonTool
{
protected override Nevron.Diagram.INDiagramElement CreateElement(bool preview)
{
NFaiencePolygonShape shape = new NFaiencePolygonShape();
shape.InteractionStyle = new Nevron.Diagram.NInteractionStyle() {
GeometryPoints = true,
PinPoint = true,
RotatedBounds = true,
Rotation = true,
Bounds = false
};
return shape;
}

}



usage is like :

nDrawingView.Controller.Tools.Add(new NCreateFaiencePolygonTool() { Name = "FaiencePolygonTool" });


To set current tool:

nDrawingView.Controller.Tools.SingleEnableTools(new string["FaiencePolygonTool"]);

Hope this helps
