Dear list,
I'm sure this is a relatively trivial problem, but I have been unable
to find any good examples/explanations on how to do this, so here
goes:
I have multi-polygon object, which is simply a list of polygons, where
each polygon is a list of lines, where each line is a list of points.
What I would like to do, is change the x and y values of each point,
all the while keeping the structure of the lists intact.
As you know the structure by advance, this is not a recusive problem :
for polygon in multi :
for line in polygon :
for point in line :
point[0] += x
point[1] += y
So in the end, the only thing that should be changed is the values,
not the lists themselves... clear as mud?
Any hints, and/or suggestions are greatly appreciated,
Carson

Hi everyone,
Is there a way to compare recursively two objects (compare their
members recursively)? I'm only interested in equality or non-equality
(no need for lower-than...).
Thx and Regards,

The style sheet shown below is from the suckerfish vertical menu.
http://www.htmldog.com/articles/suckerfish/dropdowns/example/vertical.html
I've added in a few minor changes to color code the levels.
I changed the width of the first level to 8em and get an unwanted space
between that and the 2nd level.
I'd like their to be no gap between the levels when I change the widths.
What's to change to do this?
Also, I do not understand the...

I wrote the following code to concatenate every 2 keys of a dictionary and
their corresponding values.
e.g if i have tiDict1 = tiDict1 = {'a':,'b':} i should get
tiDict2={'ab':} and similarly for dicts with larger no. of
features.
Now i want to check each pair to see if they are connected...element of
this pair will be one from the first list and one from the second....e.g
for 'ab' i want to check if 1 and 3 are connected,then 1 and...

This has been bothering me for a while. Just want to find out if it
just me or perhaps others have thought of this too: Why shouldn't the
keyset of a dictionary be represented as a set instead of a list? I
know that sets were introduced a lot later and lists/dictionaries were
used instead but I think "the only correct way" now is for the
dictionary keys and values to be sets. Presently {1:0,2:0,3:0}.keys()
will produce but it could also...

I found myself needing to find my way recursively through a document
in XSLT, finding the dependencies one element had on others, and
including only those in an initial set, their dependencies, the
dependencies of those dependencies and so on. I managed to do it, but
I'm not really happy with the method, and I'm wondering if anyone can
suggest something better.
My technique involves manipulating a string containing the names,
calling a...

Previously, I had used independent JSON lists in my code, where the lists were part of separate scripts. Because this method did not support reuse of a script without modification, I decided to consolidate all my JSON lists into one and modify my scripts so that they were more generic and reusable. So far so good.
The problem is that my JSON lists used variables for many pieces of code that performed multiple iterations to create several...

You gave the solution yourself.
I don't know if your inner polygons can contain lines and polygons, or
only lines, so:

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...

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,...
