Qt Safe Renderer Safety Manual

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.
