Introducing Qt 6

The productivity platform for the future

Next-generation UX with a single tool to design and develop 2D & 3D UIs. Limitless scalability to deploy smartphone-like UIs on ultra-low-cost hardware and advanced graphics on supercomputers. Qt 6 is the foundation we will build on to deliver the productivity platform for the future.



Latest Update

Qt 6.2

Missing features from version 5.15 implemented. Qt 6.2 is the first major release in the Qt 6 series and an ideal place to jump into the next generation of Qt.

Highlights in Qt 6

Qt Rendering Hardware Interface

Direct 3D, Metal, Vulkan and OpenGL. Write rendering code once, deploy to any hardware.

Qt Quick 3D

Merge 2D and 3D content with one stack.

Qt Quick Controls 2 Desktop Styling

Pixel-perfect, native looking controls seamlessly integrated into operating system.

HiDPI Support

Fractal scaling support allows for automatic UI scaling for different monitor configurations.

QProperty System

Increase code speed with binding support in C++, bringing the best part of QML to Qt with seamless integration to QObject.

Revamped Concurrency APIs

Mutiple CPUs, parallel computation, concurrency to keep your user interfaces fluent while doing backend logic in the background. Automatically scales tasks depending on the hardware.

Improved Networking Capabilities 

Create your own protocol backends and integrate these into the default Qt workflow, security related features are added automatically.

Automated GUI testing 

Automate functional regression tests and system tests of cross-platform GUIs and HMIs.

3D particle system

Customize your 3D particles from within Qt Quick 3D or Qt Design Studio. 

Qt coverate testing in Qt Creator

Analyze the test and code coverage of C++ and QML code.

Vertex animations

Simulate deformations of soft materials with mesh morphing or abstract representations of model movements with skeletal animation.

CMake Support

Use the industry standard build system, with its wide feature set, large ecosystem to build Qt applications.

Qt for Microcontrollers (MCUs)

Lightweight rendering engine to deploy QML based UIs on low-cost hardware with 2D hardware acceleration for optimal graphics performance with minimal footprint (>80KB RAM).

Update to C++17 

Update to latest standards​, with improved code readability, better performance​ and easier maintenance.

IDE and Tools

Qt Creator IDE

Qt 6 readiness

CMake support completely revamped and improved.

Improved use of plugins ​

Install plugin wizard to simplify extension plugin building and usage.

Ready for C++20​

Code model update to support C++20 features​

Developer Experience

Multiple shortcuts for the same action, open Qt for Python interactively, improved project loading responsiveness.

Other improvements

Support for Catch2 test framework.

Qt Design Studio

One tool for Next-gen 2D & 3D UIs with Qt 6

UI design and development tools that enables designers and developers to rapidly prototype and develop complex user interfaces. 

Asset import bridges

Import design assets from Along with 2D import from Sketch and Photoshop you can now also import assets from Figma. 

Thumbnail Generation 

Custom components now automatically generate an icon with a tooltip and full preview making it easier to get an overview.  

Item rotation 

Improved and intuitive item rotation with the new rotation tool. 

Navigator Improvements

Lock items that are complete to avoid accidental editing. Reverse the order of items to match the approach of common graphical design tools. Less visual clutter with unchecked icons now being hidden and easier spotting of component relations.
