I would like to link the contents of three OptionMenu lists. When I select an
item from the first list (call it continents), the contents of the 2nd list
(call it countries) would update. And in turn the contents of the 3rd list (call
it states would be updated by a change in the 2nd list. If anyone can share a
recipe or some ideas, I'd be grateful!
Here's some sample code that displays three OptionMenus, but doesn't update the
list...

Hi!
Have anyone ever tried to modify the Gene Cash's Tkinter tree widget
(available from http://home.cfl.rr.com/genecash/) so it supports
multiple items selection ( selection of multiple files like in Windows
Explorer - CTRL and SHIFT keys for file selection)?
Thank you in advance for any hints!
Best Wishes,

Hi,
I'm having trouble with the code below.
It's just a regular Tk text widget in which you can type and
select text as expected, however the call to tkFileDialog.askopenfilename()
seems to screw things up. After the file dialog, I can no longer use
the Text widget (typing, selecting, it doesn't work anymore!)
What am I doing wrong?
TIA,

I posted the following yesterday and got no response
and did some testing simplifying the circumstances
and it appears that deepcopy fails when the object
to be copied contains a reference to a Canvas Object.
Perhaps any Tkinter object, didn't get that far.
The problem arises because I have a geometry tutorial
with a progression of drawings and want the students to
be able to go "back". Creating "snapshots" of points

Hey,
I'm currently trying to find a way to open a dialog box that will allow
me to select more than one file at a time, so if I want to upload
select all the files in a directory, I won't have to have the number of
dialog boxes as files in the directory. I was thinking of using a
ActiveX control, but I don't want to make the sure download additional
components to be able to do this, so is there maybe some sort of
Windows ActiveX control...

Hello:
Below I have included a stripped down version of the GUI I am working on.
It contains 2 dialog boxes - one main and one settings. It has the following
problems, probably all related, that I am hoping someone knows what I am
doing wrong:
1) Pressing the Settings.. Button multiple times, brings up many instances
of the Settings Panel. I just want it to bring up one. Is there an easy
way to do that?

Hi,
I'm in the process of writing some code and noticed a strange problem
while doing so. I'm working with PythonWin 210 built for Python 2.5. I
noticed the problem for the last py file processed by this script,
where the concerned tmp file is only actually written to when
PythonWin is closed. In other words, after I run this script, one of
the generated tmp files has a size of 0kB. I then close PythonWin and
it is then written to.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
