Hi,
Is there any way that I can scroll a canvas - i.e. if there are too many
items on the canvas you can still access by pressing down. I know Form does
this (apparently) but I need to do it using a canvas!. Maybe I can attach my
Canvas to a form?
Ideas?
Oz.

Hi,
I do a "perso"widget where have two scrolls (one vertical, one
horizontal) for a canvas.
When, the first time, I added widget in the canvas, the scroll self-ajust
and when I move scrollbar, the surface's canvas "moved". But when I deleted
(.destroy) this first widgets and that a added other widget, the scrollBar
become disabled (ajust for no scroll on the canvas). What/where is the
problem?

Hi Folks,
I'm trying to click on a canvas to draw a line. The canvas has scroll
bars. All is well until I move the scrollbars. This naturally because
the relationship between my screen click and canvas event.x, event.y
has changed.
I need something that will add the proportional amount the scroll bar
has moved to the mouse click position. I see the terms canvasx and
canvasy but they appear to be used for converting screen position to

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!!

Using Tkinter, I have a Canvas with vertical Scrollbar attached. At
runtime, I dynamically create Checkboxes on the Canvas, each one on a
different row. When I add a lot of Checkboxes, instead of the
scrollbar kicking in, the Canvas resizes and subsequently, my
Application window resizes such that it is larger than my monitor.
Can I prevent the Canvas from resizing when I am creating widgets on it
at runtime? I want to use the...

I'm sure this is a simple question to the Tkinter experts - I have a
very basic Tkinter application that consists of 1 master window and
buttons within that window. My problem is that, I need to be able to
scroll (up and down) when I get to the point that the buttons go off
the screen. What's the easiest way to do this? Thanks in advance.

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:

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,...
