you need to create a pixmap without pixels and use
gdk_cursor_new_from_pixmap() ( in the C library, i belive it's not been
ported to gdkmm, so you'll need to use Cursor (GdkCursor* gobject, bool
make_a_copy=true) to create the actual object ) to create an empty
cursor and then use set_cursor( cursor ) to assign it to the window (in
your case the top-level)

There is however also 	Cursor (const Glib::RefPtr<Display>& display,
const Glib::RefPtr<Pixbuf>& pixbuf, int x, int y)  but I'm not sure
whether that will produce an empty cursor with an empty pixbuf.
