Creacion de un TreeView GTK# (Create treeview GTK# C-Sharp)

Buen Dia Amigos

Aca del dejo como crear un TreeView en GKT#, bajo monodevelop 5.10 Linux aunque tambien funciona para Xamarin Studio sin problemas

Librerias a Usar

using System;
using Gtk;
using Gdk;
using Glade;
using Npgsql;
using System.Collections;
using System.Data;
using System.Collections.Generic;







Llamada del scrip

Explicacion del arreglo

{ "Cant.", "text","","","","","true"},

0 titulo
1 tipo de la columna
2 ancho de la columna
3 R   Color
4 G   Color
5 B   Color
6 true visualiza columna   false oculta columna


void crea_treeview()
        {
           
object[] parametros = { treeview_concepto_remis,treeViewEngineconcepremis};
            string[,] coltreeview = {
                { "Cant.", "text","","","","","true"},
                { "Ref.", "text","","","","","true" },
                { "Descripcion", "text","400","","","","true" },
                { "Pre. Unitario", "text","","","","","true" },
                { "Total", "text","","","","","true" },
                { "Lote", "text","100","","","","true" },
                { "Caducidad", "text","80","","","","true" },
                { "Cod. Barra", "text","","","","","true" },
                { "Ref.", "text","","","","","true" },
                { "ID Producto", "text","","","","","true" },
                { "Nro.remision", "text","","","","","false" }
            };
            crea_colums_treeview (parametros, coltreeview,"treeview_concepto_remis");

}


Como se crea automaticamente las columnas del TreeView
