Microsoft Foundation Class Library (MFC) is a legacy C++ object-oriented library on Windows that exists since the dawn of Windows. It has been replaced lately with more up to date framework, but MFC legacy code still widely exists. While Qt and MFC are both over 25 years old, that’s where the similarity ends. Qt is actively maintained by a vibrant developer community, upgraded regularly to embrace the latest programming improvements, and expanded to cover new devices and operating systems. Qt is then a natural candidate for replacement of MFC. In this talk, we will discuss the strategy and steps to migrate an MFC legacy code base to Qt, how to map MFC code to Qt, as well as some of the traps to avoid.
