Oh.

If you just want to enforce window stacking between two toplevels in
your application, you can use "wm transient" for this.
    t = Tkinter.Tk()
    u = Tkinter.Toplevel(t)
    u.wm_transient(t)
    t.mainloop()

however, "wm transient" has other effects (TRANSIENT_STYLE, does not
appear on task bar, etc).
