Re: [g-a-devel] Which window is on top?

[David Bolter <dtb gnome org>]

Hi Sam (and hi Steve)

You might find libwnck useful:

http://library.gnome.org/devel/libwnck/stable/WnckWindow.html#wnck-window-is-above
(and wnck_window_is_below)

Note you could use libwnck API... or find out how it is implemented
under the hood :)

cheers,
David
