"root" is the name of a variable typically used by people to hold an instance of Tkinter.Tk, the main application window (from http://epydoc.sourceforge.net/stdlib/Tkinter.Tk-class.html: "Toplevel widget of Tk which represents mostly the main window of an appliation. It has an associated Tcl interpreter."). Instead of subclassing Tkinter.Tk and instantiating that subclass for my application, I could create a Tk instance and withdraw() it, then use a Toplevel. In my example code above, I could call any 'root' methods on an instance of my Application class, presumably with the same effect. In any case, that might not be important - I think the problem comes from not calling mainloop(): <code> import Tkinter import sys root = Tkinter.Tk() Tkinter.Button(root,text="Quit",command=sys.exit).pack() root.mainloop() </code> Clicking 'Quit' or on the window's 'x' causes the application to quit without messing up the terminal. With root.mainloop() commented out, though, no combination of root.quit(), root.destroy(), and sys.exit() stops the terminal from getting messed up. So, I should call mainloop() for my application...except that I want to use the commandline, too, and calling mainloop() freezes the commandline. I wonder if there is another way to use the commandline and have a GUI? I couldn't find any clear information about that. Thanks again, Chris -- http://mail.python.org/mailman/listinfo/python-list
