I came in on the back end of this, you can return any message
from/to treeview with this.

-- tagNMHDR NMHDR_hwndFrom = 0, 
    NMHDR_idFrom = 4,
    NMHDR_code = 8,
    SIZEOF_NMHDR = 12


elsif iMsg = WM_NOTIFY then

   id = peek4s(lParam + NMHDR_hwndFrom)

          if id = TreeView then              

              iMsg = peek4s(lParam + NMHDR_code)

-- with the returned value "iMsg", any of the NM_* constants
-- work as well as the TVN_* notification messages...

ofcourse win32lib's way, Im not so sure about.....
this is how standard API codeing works.
