My guess is the widgets are setting the background attribute
as well.  When realized, they invoke gtk_style_set_background which in
turn invokes gdk_window_set_background and
gdk_window_set_back_pixmap.  But it's only a guess...

Is there a reason it can't be done with styles, rather than
going to the GDK level?
  How about

 GtkStyle *new_style;

new_style = gtk_style_copy( gtk_widget_get_style(window1) );
new_style->bg_pixmap[GTK_STATE_NORMAL] =
                     gdk_pixmap_create_from_xpm(window1->window,&mask,
                      &new_style->bg[GTK_STATE_NORMAL],"./BACKGROUND.XPM");
gtk_set_style( window1, new_style );

Or have I misunderstood? (Always possible!)
