Each month KDAB schedules time for me to maintain Qt for Android port. Usually I use it to review the pending patches or fix bugs, but sometime there is a quiet month and I have time to add new functionalities or improve the existing ones. April was quite quiet so I decided to rewrite the […]

Today’s complex applications can soak up megabytes, a memory management strategy is crucial for RAM intensive applications like image/video processing, massive databases, and machine learning.
QMacTouchBar has landed Recent Apple MacBook Pro models contain an entirely new hardware feature, the touchbar. The touchbar is a touch-sensitive OLED strip sitting above the standard keyboard, where the function keys used to be. macOS uses it for some of the physical buttons that used to be located there, such as volume controls, but […]

Answer: Maybe your first thought was, well reinterpret_cast<void*>(&f) of course. That was mine, at least. Well, it turns out, C++ wants to support architectures, where data and instruction pointers are physically distinct […]
Enter the wonderful world of tools for which the announcement blog takes more time to write than the tool itself. qsslint is a small command-line utility for verifying the syntax of your Qt stylesheet files (*.qss). It’s much like KDAB’s previous linter contribution, qmllint. It simply returns 0 if the stylesheet is valid, and non-zero […]

We accumulated 500.000 plus samples of sensor data appended in a huge array. To view this growing sensor information as a waveform graph without visiting all data points in a single pass, we need to cheat...
