Modernizing Qt Widgets without a QML rewrite

说明与用途

使用 Fluent‑Qt 对 Qt Widgets 应用进行逐屏现代化，保持现有应用模型和构建流程。

问题

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

结果

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

工作流

• 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.

证据

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

来源

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.
