This means that Qt3D will […]
Reducing relocations with Q_STRINGTABLE
Qt is a native library at the heart. As a native (C++) library, it already outperforms most higher-level language libraries when it comes to startup performance. But if you’re using native languages, you usually do so because you need to get the most out of the available hardware and being just fast may not be […]

This happened around the time of the introduction of the QML language and technology stack, and so it was only natural that Qt3D should also […]

CMake 3.0 was released last week with many major new features and new Qt integration for uic and rcc. A major change with this CMake release is the new documentation system based on reStructuredText and Sphinx. Sphinx has the ability to generate Qt Assistant files, so these are now easy to create reproducibly from the […]
