C++23 is feature complete and on track to be released next year. While many people are complaining that it’s, after all, a “minor” release (as the pandemic made the Committee work very difficult), C++23 still has a few very significant changes. In this blog post, I want to talk about what I think is my […]

The Qt Less Traveled Fixing Bugs in Qt's Lesser-used Features, for Profit (and fun!)
Qt is a high quality library, but it is also massive in number of features. This massive number results in a higher likelihood that there are bugs that go unnoticed lying around in its less frequently used features or combination of features. Our friends at qgis.org hired us to solve some of those issues that had […]
CXX-Qt Safe Rust Bindings for Qt
At KDAB, we have been investigating how to integrate Rust with Qt in a safe and idiomatic way. The solution we are currently working on is called CXX-Qt. It’s available in the GitHub and on crates.io. This blog post discusses the journey of CXX-Qt — where it started, where it can be used right now, […]

Loose Coupling with Signals & Slots Connecting (Almost) Any Function to a Signal
Here at KDAB, we recently published a library called KDBindings, which aims to reimplement both Qt signals and slots and data binding in pure C++17. To get an introduction to the KDBindings implementation of signals and slots, I recommend that you take a look at the KDBindings Getting Started Guide. It will give you an […]
New KDReports Release Version 2.1.0 is Here
We have just released version 2.1.0 of our KDReports developer tool product. KDReports generates printable and exportable reports from code and from XML descriptions. Developers write the code that integrates KDReports with the rest of the application. External designers or marketing and sales staff can be tasked with creating the report structure, or its appearance. […]
Introducing KDBindings Reactive Programming and Data Binding in C++
All Qt developers should know about signals, slots, and properties. Those of you who have used QML will know that property bindings are super useful and cool. Bindings allow us to write more reactive and declarative style code. However, they are only available within QML, which means there are no compile time errors when you […]
QML Component Design The Two-Way Binding Problem and How to Avoid It
In a well-designed QML application, the UI is built using re-usable components, while the data and logic live in C++ based components we call controllers here. The QML part of the application uses these components (that themselves may be written in QML or C++) to build up the user interface and connect these components with […]
Heaptrack v1.3.0 Release
Version 1.3.0 of the KDE Heaptrack project was just released by KDAB’s Milian Wolff. Heaptrack is a heap memory profiler on Linux-based operating systems. It can help you find hotspots that need to be optimized for reducing memory usage, memory leaks, allocation hotspots, and temporary allocations. Included in this release is a special new feature […]
