Find information in Qt documentation

Qt Creator installer, Qt Online Installer, and other Qt deliverables install documentation as .qch files. View the documentation in the Help mode. To view the currently open document online, select (Open Online Documentation).

By default, Qt Creator registers only the latest available version of the documentation for each installed Qt module. To register all installed documentation, go to Preferences > Kits > Qt Versions and select an option in Register documentation.
