Fun with Paths and URLs in QML Managing Your QML Assets with Ease
There are a few small, and sometimes already quite old, features in Qt that, when combined, can be a very nice way to deal with assets in your QML application — especially if some of them live on the file system, some in a resource, and some may need localization or translation. Let’s dive in! […]
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.
Structured Bindings with Qt SQL
Some time ago, I wrote a post about integrating Qt’s associative containers with the fancy new C++ features, range-based for loops with structured bindings. That post inspired KDAB’s own Giuseppe D’Angelo to add the asKeyValueRange member function to both QHash and QMap. Now it’s possible to iterate over them with a simple range-based for loop, […]
Say No to Qt Style Sheets Making the Right Choice Between QStyle and Qt Style Sheets, Upfront
You have two choices when it comes to giving a custom style to your Qt widgets. Qt Style Sheets are very convenient for getting started — just a few CSS-like rules, and they work. It is our experience, however, that Qt Style Sheets create too much trouble and a QStyle subclass (*) gives a better […]
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, […]

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 […]
