Qt 2021 Roadmap

Take a look at whats planned for the year ahead with the following blog post.

Migration of additionally required modules to Qt 6

Qt Quick Dialogs (file dialog)

Qt SCXML

Qt Bluetooth

Qt Multimedia

Qt Multimedia Widgets

Qt NFC

Qt Positioning

Qt Quick Dialogs: folder, message box

Qt Remote Objects

Qt Sensors

Qt SerialBus

Qt SerialPort

Qt WebChannel

Qt WebEngine

Qt WebSockets

Qt WebView

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.

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. 

Figma Bridge

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.
