New to Tkinter. Initially, I had some code that was executing button commands at
creation, rather than waiting for user action. Some research here gave me a
solution, but I am not sure why the extra step is necessary.
This causes the "graph" function to execute when the button is created:
Button(root, text='OK', command=graph(canvas)))
However, this waits until the button is pressed (the desired behavior):
def doit():
graph(canvas)

Newbie. Playing with the 'turtle' module and wondering if there's a way to save
the graphics you make with it. The documentation itself has nothing to say about
this, nor (as far as I can tell) does the FAQ list at python-dot-org. Any
pointers would be very much appreciated.
(In related news, I would also like to find out what's going on with "bounding
boxes" in image files - not having them is keeping me from including images in

Please take a look at and run the code snippet shown below.
It creates a canvas with vertical & Horizontal scroll-bars.
If you shrink the window to smaller than the area of the canvas, the
scroll-bars work as advertised. That's great.
However, if you click the Left Mouse button, it calls code which
expands the width of the canvas by 100 pixels. The area being viewed
expands correspondingly..... BUT I DON'T WANT IT TO!!

Below is a simple code snippet showing a Tkinter Window bearing a
canvas and 2 connected scrollbars (Vertical & Horizontal). Works fine.
When you shrink/resize the window the scrollbars adjust accordingly.
However, what I really want to happen is that the area of the canvas
that the scrollbars show (the Scrollregion) should expand as the window
grows. It doesn't currently do this. although, if the window shrinks
smaller than the...

I need to determine the size of a canvas while the process is running.
Does anyone know of a technique that will let me do that?
Thanks,

Tkinter makes it very easy to drag jpeg images around on a
canvas, but I would like to have a "target" change color when
the cursor dragging an image passes over it. I seem to be
blocked by the fact that the callbacks that might tell the
target that the mouse has entered it (<Enter>, <Any-Enter>,
even <Motion>) aren't called if the mouse's button is down.
What am I missing? Have I failed to find the right Tkinter
document? Is Tkinter...

I hate to do this, but I've thoroughly exhausted google search. Yes,
it's that pesky root window and I have tried withdraw to no avail. I'm
assuming this is because of the methods I'm using. I guess my question
is two-fold.
1) How do I get rid of that window?
2) Any comments in general? I am just learning python (and coding with
classes), so I'm sure there are things I should pound into my head
before I learn bad habits.
Here's the...

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:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
