not pack methon in tkinter

[kuangye]

Hi, all. Why can not i find the pack method in tkinter.

code segment:

from Tkinter import *

root = Tk()
w = Label(root, text="Hello, world!")

w.pack() ###I can not find this method in Label and Label's ancesters
##So where does pack function come from??

root.mainloop()

Take a look at the Pack class in Tkinter.py, line 1765. It's a
rebinding of the method pack_configure, which is defined on line 1746.

pack = configure = config = pack_configure

Pack() is a separate class for all widgets and not specific to the
Label widget i.e all widgets are "packed" into the parent. Here is
some documentation on the pack class http://effbot.org/tkinterbook/pack.htm
