Qt CSS Engine is a Python library that adds time-based transitions and extra CSS-like properties to Qt widgets while leaving ordinary styling to QSS. The main workflow is: an application supplies a stylesheet, extract_rules returns cleaned QSS plus animation rules, the app installs the engine as an event filter, and widget state changes trigger property animations rendered through Qt. Documented branches include pseudo-state and dynamic-class transitions, stylesheet hot reload, static gradient translation, and non-native opacity/shadow properties. The graph follows documented capabilities where implementation excerpts are incomplete; those links are omitted when call ownership is not evidenced.
