The Future of QML {Qt Virtual Tech Con 2020}

The QML language and engine will face major new challenges and developments in Qt 6. In order to scale down to smaller and smaller devices, a simpler dialect of the language needs to be formulated. This dialect can then be compiled ahead of time, reducing the run-time loading overhead and allowing additional optimizations.In total there will be three dialects of QML, building on each other: Static QML is for MCUs, and allows only very simple expressions and a reduced set of elements. Strict QML offers a larger feature set that is still compilable ahead of time. Dynamic QML gives you the full power of the language and all the elements you know from Qt5, at the cost of having to interpret it at runtime. The talk will give an overview of the new architecture as well as the changes to the language. It will show what changes you need to apply to your QML files in order to compile them ahead of time in the future. Speaker: Fabian Kosmale, Software Engineer, The Qt Company Qt Virtual Tech Con 2020 was held in May 2020. 35+ live tech talks, Q&As, and more were carried out by members of the international Qt community, in a free online event for designers, developers, and technology managers; focusing on interactive learning to create high performance UI/UX, applications with the Qt framework.
