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:

Hi Michael,
For widgets that don't accept keyboard focus you can use the
highlightbackground option to create a colored border (although you cannot
add a 3D-relief this way) ... snipped
I took your example and added another frame and widgets that gain focus.

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.
1. Turn off the frame's border. Enclose the frame in a parent

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=bordercolor
- set highlightbackground=bordercolor
- set highlightthickness=borderwidth
I think that also answers the question I just posted
On 2, definitely. Rather than using fill, you could set the
outline color, style, and width (e.g. dash/stipple):

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?

via c.create_window() vs. just packing the frame?

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.

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
As a rule of thumb I'd say: *never* use update() unless you really need it.
If update_idletasks() does the job, it is to be preferred.
Thanks Michael, that's a great tip.

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:

root = Tk()

BTW, for those who want to read more about update() vs. update_idletasks(),
there are two pages on the tcl'ers wiki that discuss the potential problems
with the update() method in more detail:

The Label widget in fact REPLACES the canvas in the display
rather than being packed within it. I don't know why (try commenting out
the d.pack() line) and see the difference.)
