Qt Widgets apps use an "MVC with a twist" where controllers are tightly coupled to views and the GUI stack, capturing business logic in the UI layer. Qt Quick apps follow an MVP pattern with QML views, QObject-based proxies, and better separation of concerns. The MVP approach offers superior reusability and future-proofing, as views know about proxies but not vice versa. The Qt Widgets pattern emerged historically due to documentation examples and lack of alternatives, but transitioning to MVP architecture is possible before migrating to Qt Quick. ## Full article daily.dev links to this article rather than hosting it.
