After a long testing time I feel too tired, frustated and I'm start thinking to modify directly the C code, the DiaShapes doesn't appear why? I don't know, they just doesn't. Anyway, there are people who want to help but I can't make it work, any idea?. Lets look my class, still doesn't work but... check it out:

using Dia;
using System;
using GLib;
namespace UML
{
public class Comment :  CanvasElement
{
Shape myShape, myShape1;
CanvasIter tempX;
    static GLib.GType gtype;

    static Comment()
    {
        gtype = RegisterGType (typeof (Comment));
    }

    public Comment() : base(gtype)
    {
        initShapes();
    }

    private void initShapes()
    {
        this.Height = 150;
        this.Width = 150;
        this.myShape = new Shape(Dia.ShapeType.Path);
        this.myShape1 = new Shape(Dia.ShapeType.Image);
        this.Move(00.0, 00.0);
    }

    protected override void OnNeedUpdate()
    {

        this.myShape = new Shape(Dia.ShapeType.Path);
        this.myShape.Color = 8327327;
        this.myShape.Line(new Dia.Point(50.0,0.0), new         Dia.Point(50.0,0.0));
        this.myShape.Visibility = Dia.ShapeVisibility.Visible;

        this.myShapeX1 = new Shape(Dia.ShapeType.Path);
        this.myShapeX1.Color = 8327327;
        this.myShapeX1.Line(new Dia.Point(170.0,0.0), new Dia.Point(150.0,100.0));

        this.tempX = CanvasIter.New(this.Handle);
        this.GetShapeIter(tempX);
}

    public new bool ShapeNext(CanvasIter iter)
    {
        if (iter.Data[0] == this.myShape.Handle)
        {
            iter.Data[0] =             this.myShape1.Handle;
            iter.Data[1] = this.myShape1.Handle;
            return true;
        }
        else if (iter.Data[0] == this.myShape1.Handle)
        {
            return false;
        }
        else
        {
            iter.Data[0] = this.myShape.Handle;
            iter.Data[1] = this.myShape.Handle;
            return true;
        }
    }

    public new bool GetShapeIter(CanvasIter iter)
    {
        this.myShape = new Shape(Dia.ShapeType.Path);
        iter.Data[0] = this.myShape.Handle;
        while (this.ShapeNext(iter));
        return true;
    }
}
}

By the way, I haven't slept too much, I feel a a few tired but I need to keep going.

I learned yesterday: 'I should start learning long time ago, not today'

PS. I don't want to be dramatic, but I miss her.
