You're trying to set the bg pixmap of the screen's root window.  You 
want to set it on the GdkWindow of the widget itself:
gdk_window_set_back_pixmap(window->window, pixmap, FALSE);

Note that gtk themes that have pixmap window backgrounds set may 
override this, so you'd want to connect to the GtkWindow's style-set 
signal, and re-set the bg pixmap in that signal handler.
