Consider moving from legacy Qt Widgets code to Qt Quick? See how to complete the architecture transition and how easy it is to iterate on a new GUI.

Qt's platform is a central hub for developers and UI/UX designers, offering insights into cross-platform application development, graphical user interface (GUI) design, and software development tools. Through articles, tutorials, and documentation, Qt offers insights into building responsive and intuitive applications with Qt framework. Developers can learn about Qt widgets, QML language, and Qt Creator IDE to create modern and visually appealing user interfaces.

The final part of a four-part series on migrating a Qt Widgets application to Qt Quick. It covers completing the MVP architecture transition by moving remaining business logic into proxy classes, then adding a Qt Quick GUI on top of the established proxies. The QML-based Window integrates with PageProxy in a way that mirrors the original Qt Widgets setup. Both GUIs can coexist during transition, giving teams flexibility to migrate at their own pace. The post concludes with a 7-step migration checklist and notes that adopting MVP is valuable even for teams staying with Qt Widgets, as it improves separation of concerns and testability.
