We are happy to announce the release of KDDockWidgets version 1.7.0! What is KDDockWidgets? KDDockWidgets is a development framework for custom-tailored docking systems in Qt, to use when you need advanced docking that is not supported by QDockWidgets.

Pimpl for Small Classes
The familiar solution for thick value classes that want to preserve binary compatibility is to use the pimpl pattern (private implementation), also known as d-pointer (pointer to data). In future versions of our class, we can freely change the contents of the pimpl (i.e. adding, removing, and/or modifying data members) but the binary compatibility of […]
CXX-Qt 0.5 Released
We just released CXX-Qt version 0.5! CXX-Qt is a set of Rust crates for creating bidirectional Rust ⇄ C++ bindings with Qt. It can be used to integrate Rust into C++ applications using CMake or build Rust applications with Cargo. CXX-Qt provides tools for implementing QObject subclasses in Rust that can be used from C++, […]
QObjects, Ownership, propagate_const and C++ Evolution Const Correctness in Qt Applications
A very common implementation pattern for QObject subclasses is to declare its child QObjects as data members of type “pointer to child.” Raise your hand No, keep your hand on your computer input device 🙂 Nod if you have ever seen code like this (and maybe even written code like this yourself): A fairly common […]

Android Shared Storage Qt Wrapper A New Qt (5.x & 6.x) Library for Complete Shared Storage Access
In this article, I’d like to talk about Android storage. In recent Android versions, Google decided, for a good reason, to restrict the access to the SD card. This means, even if your application will have the old READ/WRITE_EXTERNAL_STORAGE permissions declared and granted, you won’t be able to freely access the SD Card contents like […]

Let’s say you’ve already made the decision to do a legacy software migration. So, what’s next? This blog will go over the most important steps in a legacy software migration, to help you execute your own.
KDE Frameworks – Part 3 KCoreAddons
Qt provides a rich set of high-quality, cross-platform APIs, but can't cover every possible use case. KDE has created code to fill these gaps in its many projects, sharing these libraries as KDE Frameworks.
