Qt 5 Core Compatibility APIs

The Qt 5 Core Compat module contains the old Qt Core APIs which will be no longer supported in Qt 6 and therefore were removed from Qt 6. The module is provided to facilitate transitioning the old code to Qt 6.

Using the Module

To include the definitions of the module's classes, use the following directive:

 #include <QtCore5Compat>

Building with qmake

To link against the module, add this line to your qmake .pro file:

 QT += core5compat
