I'm no Tkinter expert -- far from it. But I would assume that GetPassword, as a subclass of Dialog, creates a new window, and thus you have no need for the root window. root.withdraw() hides the root window from view, and allows the application to continue running. I imagine there are other ways to accomplish the same thing. HTH, Marty ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Modifying Grayson's Example 5_14
Title: Signature.html
I thought I'd explore Tkinter a bit more before diving into widget
design. Grayson has some examples on the web, which look like they
could help a bit. He uses Pmw, so I thought I'd just remark out the
import for it. It works pretty well, but puts up a a few probably top
level windows that are blank. How do I get around them, and is there
anything else I should be aware of in this code? It produces a small
dialog for entering a new pwd.
# Grayson 5_14.py
from Tkinter import *
from tkSimpleDialog import Dialog
import tkMessageBox
#import Pmw
class GetPassword(Dialog):
def body(self, master):
self.title("Enter New Password")
Label(master, text='Old Password:').grid(row=0, sticky=W)
Label(master, text='New Password:').grid(row=1, sticky=W)
Label(master, text='Enter New Password Again:').grid(row=2,
sticky=W)
self.oldpw = Entry(master, width = 16, show='*')
self.newpw1 = Entry(master, width = 16, show='*')
self.newpw2 = Entry(master, width = 16, show='*')
self.oldpw.grid(row=0, column=1, sticky=W)
self.newpw1.grid(row=1, column=1, sticky=W)
self.newpw2.grid(row=2, column=1, sticky=W)
return self.oldpw
def apply(self):
opw = self.oldpw.get()
npw1 = self.newpw1.get()
npw2 = self.newpw2.get()
if not npw1 == npw2:
tkMessageBox.showerror('Bad Password',
'New Passwords do not match')
else:
# This is where we would set the new password...
pass
root = Tk()
dialog = GetPassword(root)
