Modernizing Qt Widgets without a QML rewrite

Описание и применение

Модернизация экрана Qt Widgets без полной переписывания UI с использованием Fluent‑Qt, сохраняя существующую модель приложения и сборку.

Задача

Modernizing a mature Qt Widgets application one screen at a time without rewriting the entire UI stack.

Результат

A single screen can be modernized with minimal disruption, preserving the existing application model and build process.

Рабочий процесс

• 1. Add Fluent‑Qt as a CMake target via FetchContent or add_subdirectory.
• 2. Link the application to FluentQt::FluentQt.
• 3. Replace a QWidget (e.g., a button) with a Fluent‑Qt control in the existing layout.
• 4. Connect the new control to existing slots and signals.
• 5. Verify that the parent remains a QWidget and the layout stays a Qt layout.
• 6. Test on Windows, macOS, and Linux for native behavior.
• 7. Optionally use the WebAssembly gallery to preview components before integration.

Доказательства

The library links as an ordinary CMake target rather than introducing a parallel runtime.

Источник

The button itself is not the interesting part. The important point is what does not change: the parent is still a QWidget, the layout is still a Qt layout, and the control can connect to existing application slots.
