Using Web Software Architecture in Traditional Desktop App Development
The document discusses the adaptation of Flux/Redux architecture in traditional desktop app development using Qt/QML. It outlines the evolution of web and desktop development, the introduction of MVC and MVVM patterns, and the creation of QuickFlux, a Qt/QML implementation of Redux. The author emphasizes the benefits of this approach, including rapid development and a clear separation of concerns between view and application logic.
