The documentation clearly explains the MouseWheel event for a picturebox.
Unfortunately I am not able to select this from the declarations dropdown
list for the picturebox control on my form. It's not listed...
Any ideas? Is this a bug? What else can I do to react on a mousewheel
event...?
Thanks, Rud.

I have a form with buttons and a custom control I wrote showing a list of
items. I would like to scroll the list when the mouse is over the control
and the mouse wheel is moved but yet don't want to set the focus to my
control. How can I do this. Currently, I set the focus to my control when
the mouse hovers over my control but this could cause a user problems with
the lost focus event on any other control he is using at the time. It...

Hello,
when a NumericUpDown control has the focus, the mousewheel
increases/decreases its value. How does one prevent this from happening? How
does one turn off its mousewheel event?
Thanks.

(I apologize if this posts twice. My AVG is being fussy.)
From what I've read, MouseWheel is a very tricky event. I have
replaced my Python tcl84.dll and tk84.dll files with those in the
ActiveTcl distribution to fix the crashes caused by the event. Then, I
managed to see that my test script (see code below) was registering the
event by printing the delta value (+/- 120).

Hello. When I tried to make Tkinter canvas widget respond to
MouseWheel event on Windows XP, I failed. The canvas just doesn't
receive MouseWheel event. I used bind_all to find out which widget
receives this event and the result showed that only the top Tk widget
gets it. This is really annoying. I wonder if this problem exists on
other platform. I googled, but found no appliable solution, so I wrote
one as following. It's not perfect,...

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,...
