Hi everyone.!
I apologize in advance, since English is not my native language and
some things can not understand and misinterpret.
Very recently I found Python and Tkinter. Needless to say, I find a tool
Tkinter extremely cool and functional, which I am discovering little by
little every day.

1. So the proper way to use Canvases as containers for traditional
widgets is to manually handle layout and place all widgets via the
create_window() method.

You can easily add widgets to a canvas just like you do any other

Hi Malcom,
I have never heard of packing widgets within a canvas. Just use create_window,
so there is no automatic placement, you need to handle all placement.
Note with the following, packing a label within a canvas:
from Tkinter import *
root = Tk()
c=Canvas(root, bg="red", width=400, height=4

Thanks Michael, that's a great tip.

This question is related to using Canvases and Frames as
containers and does not consider the drawing capabilities of the
Canvas widget.
Canvas and Frames are both containers. My understanding is that
both of these containers provide identical layout behaviors via
their pack, grid, and place metho

I've seen the term "stipple" mentioned in recent posts. The
Tkinter documentation is woefully short on details here. I've
googled for examples and found very few. For those with the same
question as me, here's one example.

Looking for some advice on when to use .update() vs.
update_idletasks(). Are there use cases that favor the use of one
of these techniques vs. the other? Are there situations where one
of these techniques should always or never be used?

Michael,
Your code works wonderfully - thank you very much!!
One question: Why did you add your inner frame to the canvas as a window
via c.create_window() vs. just packing the frame?
I tried the frame packing technique per the following code change
(replacing c.createwindow with pack):

Michael,
Ah, I see! The trick seems to be:
- don't set a frame's border width or relief properties (or reset them
to 0 and 'flat')
- set highlightcolor=
- set highlightbackground=
- set highlightthickness=

I understand that Tkinter frames do not have a property that
allows their border color to be customized.
Here are some high level ideas I have on how to create a colored
border effect - any suggestions on best practice appreciated.

Hi Cristian,
The problem is, self is only defined within the class definition.
Basically, the function are not part of the class, just called by the class.
We use a lambda to get the class passed to the function.
So, to correct your code:
from Tkinter import *
class MyApp:
def __init__(self
