Is Qt Right for Your Project? Factors to Consider When Choosing a Software Stack
One of the most difficult choices to make when starting any new software project is that of the programming language and framework your team will use to create it. Should you stick with Qt because it’s the best tool for the job? Should you switch to something that uses web-based technology or is designed explicitly […]
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 […]

With Apple moving to Apple Silicon for all of their new products, software developers are having to figure out how to support both Intel and Apple Silicon devices. Like some of our customers, you may not be ready to move to Apple Silicon. Unfortunately, that doesn’t necessarily exempt you from dealing with universal binaries, especially […]
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.
KDAB at Embedded World 2022 in Nuremberg June 21st - 23rd
After two years of frustration and delays, Embedded World is finally back and KDAB was there at the Qt booth, number 258 in Hall 4. As usual we showed some great demos – updates to some golden oldies, and some brand new ones. We were impressed at the number of visitors who turned up, as […]
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, […]
