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
