Now I'm reading a Tkinter reference at
http://infohost.nmt.edu/tcc/help/pubs/tkinter/minimal-app.html
and it has this example:


#!/usr/local/bin/python    =20
from Tkinter import *      =20

class Application(Frame):             =20
    def __init__(self, master=3DNone):
        Frame.__init__(self, master)  =20
        self.grid()                   =20
        self.createWidgets()

    def createWidgets(self):
        self.quitButton =3D Button ( self, text=3D'Quit',
            command=3Dself.quit )       =20
        self.quitButton.grid()        =20

app =3D Application()                   =20
app.master.title("Sample application")=20
app.mainloop()


Is this just outdated? I don't understand why it uses quit() instead of des=
troy(). When I try this in IDLE, quit() just causes the application to hang=
 (I assume because it ends the mainloop without actually closing the applic=
ation). Or is this just a problem when using IDLE?

If the latter, which is preferable, quit or destroy?
