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 […]
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 […]
KDFunctionalSortFilterProxyModel A Functional Sort/Filter Proxy Model
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 […]
KDE Frameworks – Part 2 Extra CMake Modules for Enhancing Your CMake Code
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.
VS Code for Qt Applications – Part 3 A Technical Guide
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…
Fun and Scary Code from Qt and KDE
These are some really cool or obfuscated code snippets for your amusement. We didn’t want to rate them, so the order doesn’t mean anything at all 🙂 Just to make sure that there’s no misunderstanding: This code really is/was in the Qt or KDE repositories. From Kivio, main.cpp From Qt 2.2.1 (src/canvas/qcanvas.cpp) Writing code that […]
Wayland on Windows Run a Wayland Compositor Directly in Your Windows Machine
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.
Auto-Accepting in QSortFilterProxyModel Since Qt 6.0, QSortFilterProxyModel Can Auto-accept Child Rows of Rows Matching the Filter.
In Qt 5.10, we added support for recursive filtering in QSortFilterProxyModel, which means keeping all parents of items matching the filter. One of the comments in the blog post about that feature was “Sometimes, you do not only want to show parents for a match (so the match is visible), you may (also) want to […]
