What's New in Qt 6
Qt 6 lets you develop applications with intuitive user interfaces for multiple devices and platforms, faster than ever before. Development is easy with Qt Creator, letting you design, code, test, and deploy Qt applications. Qt 6 is highly compatible with Qt 5. Developers of Qt 5 applications can move seamlessly to Qt 6 while retaining applications' functionality.
Developing User Interfaces with Qt
Qt Quick Designer lets you design UIs from within Qt Creator. You can import 2D and 3D assets, animate components, and create layouts. Testing the designs is possible through a live preview on devices are through an online browser.
Qt Creator is a complete IDE for developing Qt applications. You can setup project files, code, debug, package, and deploy from within Qt Creator. New in Qt 6, projects can use either CMake or qmake to build applications.
Qt is cross-platform and you can deploy onto different devices and platforms. Qt Creator has built-in project templates and kits for different platforms and devices. In addition, you can port Qt and create custom targets with Qt Platform Abstraction.
