Do i need to set a callback to a canvas
in order to listen to the root window
being resized in order to make it adjust
its contents?
If so, how? If not, how do i make the
canvas draw a line from one corner to
an other?
import Tkinter as tk
root = tk.Tk()
canvas = tk.Canvas(root)
How do i change the size of a Button
(using Tkinter), other than to set it
during construction?
I've found methods for getting the
size but not applying them.
I've been laborating with .setvar(*)
but i've been unsuccessful.

How do i change the size of a Button
(using Tkinter), other than to set it

In Tkinter, usually the geometry managers
(such as pack) are the ones who size the
widgets. If you run something like:
import Tkinter as tk
root = tk.Tk()
def change_size():
What i wish to do is to affect the size
of the button but not due to change of
text but due to resize of the frame it
resides in.
This is done by the layout manager, too:
import Tkinter as tk
root = tk.Tk()
button = tk.Button(root, text=42)
button.pack(fill=tk.BOTH, expand=True)
What I really can't stand are the
pointy-haired comment blocks at the
beginnings of C/C++ functions that do
things like tell you the name and return
type of the function and list the names
and types of the parameters. Gee, thanks.
I never could have figured that out from
looking at

the method of Alexander The Great.

public Proj2D get2Dfrom3D(Proj3D param);
The above is, to me, very clear and
consistent. Not to mention, easily
handled with e.g.
I entered the code from tkinter.pdf, section
2 but for reason, the application doesn't
close as i press the quit-button.
The wondow itself vanishes if i click the

Where can i download it? Am i actually
expected to read the whole book? How
many people actually do aply it?
2. You should use two spaces after a
sentence-ending period.
For heavens sake, why? I've always been
obstructed by the double blanks but
tolerated them. Now, that i read that
it actually is a recommendation, i need
to ask about the purpose.

Personally, I dislike double spaces after
sentences, but it is not wrong to put them
there any more than it is wrong not to put
them there.

didn't hear you say that...
I'm unclear if your teacher was a double or
single spacer. It's only
