The Qt/MFC Migration Framework tool assists in the migration of existing Win32 or MFC applications to the Qt toolkit.

The project provides a set of classes that allow using Qt and MFC/Win32 windows in the same application. User interface elements developed with Qt can be embedded into an existing MFC or Win32 based user interface, and existing custom controls developed with MFC or Win32 can be integrated into Qt widgets.

Required Libraries:

QtCore, QtGui

Please refer to the Qt Editions Comparison Chart for which Qt products include these libraries.
