|Qt 6 Released|
|Thursday, 17 December 2020|
Qt 6 has been released with improvements including a new graphics architecture and programming language improvements. The tools within Qt have also been unified and made easier to use.
The first improvements to the new release are to the graphics architecture. The Qt rendering hardware interface now supports Direct 3D, Metal, Vulkan and OpenGL, meaning developers can write rendering code once then deploy to any supported hardware. There's also a new Quick 3D option that lets you merge 2D and 3D content with one stack. HiDPI fractal scaling support has been added to support automatic UI scaling for different monitor configurations.
The support for programming languages has also been improved. The QProperty system adds binding support in C++, and the developers say this brings the best part of QML to Qt with seamless integration to QObject. The concurrency APIs have been revamped so developers can use mutiple CPUs, parallel computation and concurrency to keep user interfaces fluent while doing backend logic in the background. The APIs automatically scale tasks depending on the hardware.
Strings and Unicode support has been improved, and Qt has been fully aligned with Unicode. QList has also been improved.
Networking has been improved and developers can create custom protocol backends and integrate these into the default Qt workflow.
The C++ support has been updated to C++17 with improved code readability, better performance and easier maintenance, and CMake support has been added.
Qt 6 for Python has also been released, with many of the same improvements. For Qt for Python, Shiboken, the Python binding generator that Qt for Python uses to create the PySide module, has been radically reorganized and reworked with new features.
The developers say that for the binding generation, they've added more options to the type system, for example enabling selecting the order of function overloads to use in the decisor. They've also made it possible to declare properties. On the C++ support for the binding generation, the interaction with smart pointers has been improved and extended to handle the modern C++ features used in Qt 6 including the template type alias from QVector to QList, new exception specification keywords, and operators written as hidden friends.
