X-LINUX-QT is an STM32 MPU OpenSTLinux Expansion Package that targets Qt based application and graphical user interface (GUI) development for the STM32MP25xx series microprocessors. It contains Linux® Qt™ Frameworks, as well as an ST Application Launcher based on Qt™ Framework and application examples to get started with Qt application development.

The Qt framework contains a comprehensive set of highly intuitive and modularized C++ library classes and is loaded with APIs to simplify your application development. Qt produces highly readable, easily maintainable and reusable code with high runtime performance and small footprint – and it's cross-platform.

This expansion package is a complete ecosystem that allow developers working with OpenSTLinux to create Qt based application very easily.

• All-in-one Qt solutions for the entire STM32MPU serie supporting Wayland and Weston.
• Pre-integrated into Linux distribution based on ST environment
• Include Qt frameworks to build UIs and Applications
• Include ST Application Launcher based on Qt framework for MPU devices (see supported platforms list)
