GTK 4 Documentation

Please refer to GTK 4 API Reference and GNOME Developer Documentation Website for further information.

These websites were opened in August of 2021. The old documents are located at GTK Reference Manual and GNOME Developer Center.

If you want to know about GObject and the type system, please refer to GObject tutorial. GObject is the base of GTK 4, so it is important for developers to understand it as well as GTK 4.

Contribution

This tutorial is still under development and unstable. Even though the codes of the examples have been tested on GTK 4 (version 4.10.1), bugs may still exist. If you find any bugs, errors or mistakes in the tutorial and C examples, please let me know. You can post it to GitHub issues. You can also post updated files to pull request. One thing you need to be careful is to correct the source files, which are under the ‘src’ directory. Don’t modify the files under gfm or html directories. After modifying some source files , run rake to create GFM (GitHub Flavoured Markdown) files and run rake html to create HTML files.

If you have a question, feel free to post it to issue. All questions are helpful and will make this tutorial get better.
