This Safety Manual is for Qt Safe Renderer version 2.0.

The Qt Safe Renderer module provides a UI rendering component that can be used to render safety-critical items, such as warning indicators, in functional safety systems. Qt Safe Renderer separates the safety-critical rendering from the other parts of the system. This ensures that Qt Safe Renderer is able to render the safety-critical UI elements even if there are failures in the main UI. With separation, Qt can be used in a system requiring certification without changing the Qt libraries.

Qt Safe Renderer provides a seamless integration with the Qt toolchain. The QML language, Qt Design Studio, and Qt Creator can be used together with Qt Safe Layout Tool to generate layout data for safety-critical UI elements.
