Ignoring the fact that the Tkinter.Optionmenu is by far the worst widget in the toolkit, not to mention that the whole idea of "Tkinter X_Variables" was a poor attempt to reuse code at the expense destroying the simple and intuitive interface of "get" and "set"; here is your answer:
## START CODE ## from Tkinter import * master = Tk() variable = StringVar(master) variable.set("one") # default value optMenu = OptionMenu(master, variable, "one", "two", "three") optMenu.pack() # Get the menu menu = optMenu.nametowidget(optMenu.menuname) menu.configure(font=('Impact', 30)) mainloop() ## END CODE ## PS: You could have probably intuited the answer yourself if you used the dir() function on "w". Of course you probably would have expected the Optionmenu to have a reference to the submenu. It does, however not a direct reference. PPS: Or, if you prefer information overload you could have called "help(w)". -- http://mail.python.org/mailman/listinfo/python-list
