A series of tutorials on building a simple mobile chat application with push notifications, using a REST API powered by Cutelyst, an async database to store conversations and Firebase for notifications.
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 […]
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 […]
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 […]
Another day, another small addition to KDToolBox, KDAB’s collection of miscellaneous useful C++ classes and stuff. In this post, we’re going to talk about KDFunctionalSortFilterProxyModel, which is a convenience subclass of QSortFilterProxyModel. What’s a proxy model to begin with, and what’s QSortFilterProxyModel? Well, that explanation requires a bigger space than what I have in this […]
We just released KDDockWidgets 1.5.0! 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. It was created by Sergio Martins as a time-saving alternative to QDockWidgets. The ease-of-use of KDDockWidgets can save you lots of frustration […]
This 3-part blog series shows in detail how to get up to speed with a Qt project using Visual Studio Code. Part 3 further integrates Qt into VS Code with syntax highlighting, Qt Creator quick switch and more…
GammaRay 2.11.3 has been released! GammaRay is KDAB’s software introspection tool for Qt applications. Leveraging the QObject introspection mechanism, it allows you to observe and manipulate your application at runtime. This works both locally on your workstation and remotely on an embedded target. Version 2.11.3 will be the last in the 2.11 series. After this […]
Qt provides both a Wayland platform to run Qt applications as Wayland clients in a Wayland compositor and a library to build that, but only on Linux. The WSL subsystem makes that possible on Windows.
If you ever need to create a project around a single C++ file (or just a few C++ files) in CMake, as you might for quick test cases, you might find it tedious to write a CMakeLists.txt file by hand every time. To make this easier, I’ve written a script called cmake-project that you can […]
