You can realize the widget or use a window that it's realized, for example:

/* in anywhere of code */
GdkWindow	*rootw;

	rootw = gdk_window_foreign_new(GDK_ROOT_WINDOW());

	pdata = gdk_pixmap_create_from_xpm(rootw, &mask, &style->bg[GTK_STATE_NORMAL],
			"PixmapIWantToShow.xpm");
	gtk_widget_show(pixm1 = gtk_pixmap_new(pdata, mask));
	gtk_fixed_put(GTK_FIXED(area), pixm1, 10, 10);
