Scroll WIndow with GtkTreeView

["Sailaxmi korada " <sai korada xilinx com>]

Hi folks,
  In my application, I'm placing my TreeView widget in a scrolled window.
When I'm scrolling down the list, my headers are getting scrolled up, so
they are no more visible. Is there any way to retain the headers in the
visible area of the window. Thanks in advance

Regards
