How to painlessly migrate from MFC to Qt
summary
Shows an incremental migration path that keeps MFC running while replacing UI pieces with Qt, using QtWinMigrate to merge event loops and host QWidget inside CWnd and Qt Visual Studio Tools to add .ui, moc and uic to the MSBuild project. Claims migration beats a full rewrite past roughly 30–60k LOC. Demonstrates automated conversion of MFC resources to Qt .ui, preserving feature parity in a mixed MFC‑Qt app, notes focus and drag‑drop caveats, and reports the approach works in real customer projects.
