I'm trying to make a custom entry widget, as in the code that follows.
There are two problems I'm trying to fix:
1) I would like the widget to behave as myEntry.Escape() does now,
except that it happens on loss of focus, not when pressing Esc.
2) TABbing between multiple entry fields does undesired things with
the selection, and with cursor placement.
Can anyone offer any suggestions for how to fix this? I'm attemting to

Hi everyone,
I'm building a GUI in which I want, amongst other things, for people to
fill in there postal code. The postal codes of my country (Holland) are
in this format: 1234 AB
So for the input I use two entry widgets, one of a length of
(characters) for the numbers and one of lenght 2 for the letters. What I
don't like is that although the visible part of the widgets thus are 4
and 2 characters, users can actually input more...

I'm coming to Tkinter from Tcl/Tk. In Tcl I can get a variable in an event
using the %<X> substitution mechanism. For example, I can set up a command
like:
entry .e -validate 1 -vcmd "checkkey %d"
knowing that the '%d' will be replaced by something useful - whether the
entry widget has recieved an insert or deletion in this case. The checkkey
procedure will recieve "insert", "delete" or whatever as its first
parameter.

If I create a Tkinter.Entry widget, I can adjust the background and the
text colours, using the background and foreground options. However, if
the state is "disabled", then this has no effect and it just appears as
grey on a light grey background. E.g.,
Tkinter.Entry(root, foreground="black", background="white",
state="disabled").grid()
does not do what I expected. What is the correct way to adjust the
foreground and background on...

Earlier I asked about limitting what a user can enter in an Entry. I
got a few greatly appreciated replies, but I was hoping it would be
possible to take a more direct approach, that is, is there a method I
can override, when creating a class that inherits the Entry methods,
that is called whenever the user enters a key? I'm thinking something
like this in the override version:
def method(self, key):
if key in "1234567890":...

old one.

I seam to have noticed this a bit late but it appears to me that

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,...
