Pygtk: How to remove title bar from a window

[Nick Atkins]

Hi all,

I am writing an application using pyGTK that has several pop-up dialogs
that show and hide in succession.  I would like to prevent the user
from closing the dialog   and if possible I'd like to use a "title
bar-less" window with a normal border so the X is not even available to
click.  Is this possible?  I have tried using
window.set_decorated(FALSE) but this also removes the border making the
window look quite strange.

Thanks,

Nick.
