[Gtk-sharp-list] Editable Combo Box

[a a]

     With your example I require a separate button for
Add,Modify and Delete and capture the change and
update the combo list.
     I need to acheive the operations without having
EXTRA BUTTONS as described below. Any other logic
WITHOUT buttons is also ok to me.

  By default the Combo Entry field has all the items
separated by a semicolon(say some escape character )
By add/modify/delete on Combo dynamically I meant
Add:
    On clicking the arrow field the combo box should
list the items and the entry field should become empty
so that the user can type a new item to add to the
list.
Modify:
    The user selects one of the items from the list
and the entry contains that item. He then alters the
item and is considered as a modify.
Delete:
    Same as modify, but he removes the entire text.
Empty fields are not allowed.
    
Thanks,
A.
