Querying the desktop dimension (size) from the WM

[Hans Kramer <Hans Kramer xs4all nl>]

Hi,

If you call gdk_window_maximize, your window will be neatly (I guess
depending on the actual window manager) maximized taking into account
the panels a user has running.
Looking at the code I show that this is handled by the window manager.
My question now is: is it possible to just obtain (query) only the
dimension of the available desktop from the WM. Thus without actually
having to maximize a window! (I would like to have two toplevel windows
occupying the whole available desktop ;-)

Thanks in advance,

Hans.
