Tk: filling a frame with a widget

[Paolo Pantaleo]

I have this code

from Tkinter import *

root=Tk()
Button(root).pack(fill=BOTH)
root.mainloop()

I would expect the button filling all the client draw area of the
Frame, but when I resize the root window the button becomes wider, but
not higher ( I get some empty space under the button). How could set
the button to fill always all the space available?

Well maybe some other solution exists, since my problem is this:

I have a resizable window and i want to keep it filled with a Canvas
displaying an image (PhotoImage). Can I get the in some way the size
of the clien draw area of the window containig the canvas?

Thnx
PAolo

you also need to expand it as in
from Tkinter import *

root=Tk()
Button(root).pack(expand=1,fill=BOTH) #HERE use expand=1 as extra
option
root.mainloop()
