Event-driven flows -- Andrzej Krzemieński

By Blog Staff | Dec 22, 2025 10:06 AM | Tags: None

This post is in response to two claims about coroutines: 1) Their reference function parameters may become dangling too easily, and 2) They are indistinguishable from regular functions from the declaration alone.

Event-driven flows

by Andrzej Krzemieński

From the article:

A canonical example of an event-driven flow is the handling of signals in C. Signals will be risen at unpredictable points in time, so rather than actively checking for them, we define a callback and associate it with the indicated signal:

signal(SIGINT, on_interrupt);

 

After having performed this association, we move on to doing other things. It is the implementation (system, or parts of the program we do not write) that will make sure to invoke the callback when the signal is risen (if at all). We can illustrate it with a diagram:

Qt Jenny 1.0 Released -- Rami Potinkara

By Ville Voutilainen | Dec 20, 2025 03:00 PM | Tags: None

Qt Jenny is a Java/Android JNI glue/proxy Qt code generator. You can find and get it from Maven Central. Qt Jenny is a fork of Jenny from LanderlYoung. The fork differs from the original one by supporting JNI call gluing with QJni - classes such as QJniObject. That brings the powers of Qt for Android and the magic of Android Java native APIs to Qt!

Qt Jenny 1.0 Released

by Rami Potinkara

From the article:

Have you heard about Jenny? No, I do not mean, the girl next door, nor the Spinning Jenny that started the industrial revolution in England in the 17th century. This one is a modern information age revolution, a code generator, a cuter Jenny. Got your eyebrows raised? Are you a Qt developer? Perhaps you are mastering cross-platform development with Qt and deploying apps to Google Play? Read more below!

Converting Between Unicode UTF-16 and UTF-8 in Windows C++ Code -- Giovanni Dicanio

By Giovanni Dicanio | Dec 19, 2025 03:12 PM | Tags: None

Very often the need arises in Windows C++ programming to convert text between Unicode UTF-16 (which historically has been the native Unicode encoding used by Windows APIs) and UTF-8 (which is the de facto standard for sending text across the Internet and exchanging text between different platforms).

Converting Between Unicode UTF-16 and UTF-8 in Windows C++ Code

by Giovanni Dicanio

From the article:

A detailed discussion on how to convert C++ strings between Unicode UTF-16 and UTF-8 in C++ code using Windows APIs like WideCharToMultiByte, and STL strings and string views.

C++ Standard Evolution Viewer -- Jason Turner

By Blog Staff | Dec 19, 2025 06:58 AM | Tags: None

Explore how the C++ standard evolved across versions with interactive side-by-side diffs

C++ Standard Evolution Viewer

by Jason Turner

From the article:

This site provides an interactive way to explore changes in the C++ standard by viewing side-by-side diffs of individual sections (identified by stable names like [array], [class.copy], [ranges.adaptors]).

Each version transition below focuses on Tier 1 sections (major library components and language features) to provide the most educational value.

PVS-Studio 7.40: support for Visual Studio 2026, Qt Creator 18, UE5 Horde

By Andrey Karpov | Dec 19, 2025 05:14 AM | Tags: ue5 sast qt creator 18 qt pvs-studio misra horde

PVS-Studio 7.40 has been released. The new version brings support for Visual Studio 2026 and Qt Creator 18, adds analysis of .NET 10 projects, enhances C# diagnostic rules, and includes other new features.

PVS-Studio 7.40: support for Visual Studio 2026, Qt Creator 18, .NET 10, and more

by Gleb Aslamov

From the article:

The new release introduces support for the fresh Visual Studio 2026. We're glad to present PVS-Studio plugin for Qt Creator 18.x. The plugin lets you run static analysis, view warnings, and handle your code directly within your IDE. Unreal Engine 5.5 brings a new tool called Horde, a platform that enables users to leverage CPU cycles on other machines to accelerate workloads. We've updated the documentation section on working with Unreal Engine projects and included instructions for using the analyzer in the Unreal Build Accelerator distributed build system.

Structured iteration -- Andrzej Krzemieński

By Andrzej Krzemienski | Dec 15, 2025 03:44 PM | Tags: None

It is relatively easy to get your for-loops wrong. Luckily, C++ offers more and more bug-proof alternatives.

Structured iteration

by Andrzej Krzemieński

From the article:

These problems do not occur when you use the range-based for-loop.

This C++11 addition, apart from other conveniences, is a safety feature (as in language-safety): it is very hard to use it incorrectly. It is not flexible, or versatile. You have to pass it a range, you have to give a name to an element referenced in each iteration step. There is no "control variable" (like i), so you cannot get the operations on it wrong. A number of bugs are prevented simply by employing a range-based loop.

But what if my iteration is more complicated? What if I need to visit my elements in reverse?
