OK.  I give.  Here's the whole reason I'm trying to do this.

At the top of the program:
--------------------------

# Fonts: a constant nagging problem

System = sys.platform[:3].lower()
ScreenWidth = Root.winfo_screenwidth()
if System == "win":
    if ScreenWidth <= 1024:
        Root.option_add("*Button*font", "Helvetica 8 bold")
        Root.option_add("*Menu*font", "Helvetica 8 bold")
        CascadeFont = "Helvetica 8 bold"
        Root.option_add("*Text*font", "Courier 10")
    elif ScreenWidth <= 1400:
        Root.option_add("*Button*font", "Helvetica 12 bold")
        Root.option_add("*Checkbutton*font", "Helvetica 12")
        Root.option_add("*Entry*font", "Helvetica 10")
        Root.option_add("*Label*font", "Helvetica 12")
        Root.option_add("*Menu*font", "Helvetica 12 bold")
        CascadeFont = "Helvetica 12 bold"
        Root.option_add("*Radiobutton*font", "Helvetica 12")
        Root.option_add("*Text*font", "Courier 12")
elif System == "sun":
    Root.option_add("*Button*font", "Helvetica 10 bold")
    Root.option_add("*Checkbutton*font", "Helvetica 10")
    Root.option_add("*Entry*font", "Courier 10")
    Root.option_add("*Label*font", "Helvetica 10")
    Root.option_add("*Listbox*font", "Courier 10")
    Root.option_add("*Menu*font", "Helvetica 10 bold")
    CascadeFont = "Helvetica 10 bold"
    Root.option_add("*Radiobutton*font", "Helvetica 10")
    Root.option_add("*Text*font", "Courier 11")
elif System == "lin":
    Root.option_add("*Button*font", "Helvetica 12 bold")
    Root.option_add("*Checkbutton*font", "Helvetica 12")
    Root.option_add("*Entry*font", "Courier 12")
    Root.option_add("*Label*font", "Helvetica 12")
    Root.option_add("*Listbox*font", "Courier 12")
    Root.option_add("*Menu*font", "Helvetica 12 bold")
    CascadeFont = "Helvetica 12 bold"
    Root.option_add("*Radiobutton*font", "Helvetica 12")
    Root.option_add("*Text*font", "Courier 12")
Root.option_add("*Button*takeFocus", "0")
Root.option_add("*Checkbutton*anchor", "w")
Root.option_add("*Checkbutton*takeFocus", "0")
Root.option_add("*Entry*background", "white")
Root.option_add("*Entry*foreground", "black")
Root.option_add("*Entry*highlightThickness", "2")
Root.option_add("*Entry*highlightColor", "blue")
Root.option_add("*Entry*insertWidth", "3")
Root.option_add("*Listbox*background", "white")
Root.option_add("*Listbox*foreground", "black")
Root.option_add("*Listbox*takeFocus", "0")
Root.option_add("*Radiobutton*takeFocus", "0")
Root.option_add("*Scrollbar*takeFocus", "0")
Root.option_add("*Text*background", "black")
Root.option_add("*Text*foreground", "grey")
Root.option_add("*Text*takeFocus", "0")
Root.option_add("*Text*width", "0")

Then in another section:

    Top.add_cascade(label = "Options", menu = Op, font = CascadeFont)
    Help = Menu(Top, tearoff = 0)

    Help.add_command(label = "About", command = about)
    Top.add_cascade(label = "Help", menu = Help, font = CascadeFont)
    return
# END: makeMenu

Do you see the CascadeFont variable?  I want to get rid of that and turn 
setting the font of the .add_cascade items into an option_add function. 
Does anyone know how to do that?  What key word and tricky phrase does the 
option_add function need?
