Qt/MFC Migration Framework

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.

This Qt Solutions component is for Qt 3. For Qt 4 Solutions, please visit the Qt 4 Solutions Catalog.

Changes:

• 1.3: QWinWidget is now deleted if the only child is a QDialog and it's being hidden, because QDialog does not receive close events.

• 1.3: No longer does idle-processing if the event goes to a Qt widget.
• 1.2: Integrate Qt and Win32 focus chains for QWinWidget.
