[Gtk-sharp-list] Draging text/uri from external app to widget

[ub]

ok, i got it now :-)
i translated the tutorial from http://scentric.net/tutorial/sec-dnd.htm 
, which seems to do exactly what i want, and it even works ;)
here is my test-source, just in case anyone got the same problem:

using System;
using Gtk;

public class MyWindow : Window {
    enum bla{
      TARGET_STRING,
      TARGET_URL
    };
    static Gtk.TargetEntry[] targetentries =
    {
        new TargetEntry ("STRING",        0, (uint) bla.TARGET_STRING ),
           new TargetEntry ("text/plain",    0, (uint) bla.TARGET_STRING ),
           new TargetEntry ("text/uri-list", 0, (uint) bla.TARGET_URL 
),             
      };

   
    public MyWindow () : base ("MyWindow")
    {
        this.SetDefaultSize (400, 300);
        this.DeleteEvent += new DeleteEventHandler (OnMyWindowDelete);
        this.ShowAll ();
          Gtk.Drag.DestSet(this, Gtk.DestDefaults.All, targetentries, 
Gdk.DragAction.Copy|Gdk.DragAction.Move|Gdk.DragAction.Link);
          this.DragDataReceived += new DragDataReceivedHandler(on_drop);
    }
   
    void on_drop (object o, DragDataReceivedArgs args)
    {
        Console.WriteLine(System.Text.Encoding.UTF8.GetString 
(args.SelectionData.Data));
    }
   
    void OnMyWindowDelete (object o, DeleteEventArgs args)
    {
        Application.Quit ();
    }
}
