                    GetKeypressDialog

    Open a dialog box which returns when a valid key is pressed.

    Arguments are:
    master - a Tkinter widget (defaults to None)
    title - a string for the title bar of the widget
    text - a string to display as the text in the body of the dialog
    key_list - a list of acceptable keys, e.g. ['q','1','2','<Return>']

    The following example will print whatever character was pressed:
    d = GetKeypressDialog(key_list=['q','1','2','<Return>','<Escape>'])
    print d.result

    The implementation is somewhat obscure because a new Tk/Tcl
    interpreter may be created if this Dialog is called with no
    master widget.
