The QtWinExtras module has been deprecated and is no longer part of Qt.

The functionality of the module has been incorporated into other parts of Qt, or in some cases removed due to being obsole or better suited as cross platform APIs.

For more details, see QTBUG-89564 in the Qt issue tracker.

To learn more about how to port from QtWinExtras to alternative APIs please visit the Qt 6 porting guide.

To work on patches for the Qt 5 series, check out a local branch of the relevant Qt version, e.g.:

$ git checkout 5.15
Branch '5.15' set up to track remote branch '5.15' from 'origin' by rebasing.
Switched to a new branch '5.15'

To inspect the code in the dev branch prior to its removal, follow these steps:

$ git checkout -b my-dev dev~1
Switched to a new branch 'my-dev'
