how to attach a pixmap to a GtkWindow as the background

[Jiang XU <jiang xu echostar com>]

Since  this function 'gdk_window_set_back_pixmap` only supports
GdkWindow, but my application is using GtkWindow which let me can add
other widgets to the window.
So I wonder how I can attach a pixmap to a GtkWindow as the background?
Or, How to get the associate GdkWindow from a GtkWindow, so that I can
use that function?
Or, How to create a GtkWindow from a GdkWindow which is already get a
pixmap background by using that function.
Or, any other way?

If anyone know, please teach me ASAP, it is very urgent!!!!  because I
must attach a pixmap to a GtkWindow as the background now.

Thanks very much!

use 'gdk_window_set_back_pixmap(GdkWindow *window, GdkPixmap *pixmap,
gint parent_relative)'
