You didn't show the GtkPixmap:
     gtk_widget_show (PixmapUp);

I've recently changed the Glade output for creating pixmaps. I realized you
don't need to
pass a background colour if you are going to use transparent pixels to create
a mask.
I also now use the colormap to create the pixmap instead of an X window, so
you don't need
to realize the widgets first, e.g.

  GdkColormap *colormap;

  colormap = gtk_widget_get_colormap (widget);
  glade_pixmapup = gdk_pixmap_colormap_create_from_xpm (NULL, colormap,
&glade_maskup,
							NULL, "./icons/up.xpm");
  PixmapUp = gtk_pixmap_new (glade_pixmapup, glade_maskup);
  gdk_pixmap_unref (glade_pixmapup);
  gdk_bitmap_unref (glade_maskup);


I think this is the correct way to do it. But I'm not 100% sure.
