[Gtk-sharp-list] Problem with a ScrolledWindow

[tapia]

Hi. 

I'm trying to switch some widgets in a ScrolledWindow. The idea is
extract the child widget, and insert another one. The new one is a gecko
WebControl, so I have to insert it with AddWithViewport. 

The result I have is an empty scrolledwindow, and the WebControl showing
in another window! 

This is the code: 

itemShelf.Unparent (); 
if (swItems.Child != null) { 
      swItems.Remove (swItems.Child); 
} 
swItems.AddWithViewport (itemShelf); 
swItems.ShowAll(); 

Do you see something strange? Am I doing something wrong, or is it a
gtk# bug? 

Thank you all. 

C.
