The latest version of the tutorial is located at [GTK4-tutorial GitHub repository](https://github.com/ToshioCP/Gtk4-tutorial).

You can read it directly without download.



There's a [GitHub Page](https://toshiocp.github.io/Gtk4-tutorial/) which is the HTML version of the tutorial.



#### GTK 4 Documentation



Please refer to [GTK 4 API Reference](https://docs.gtk.org/gtk4/index.html)

and [GNOME Developer Documentation Website](https://developer.gnome.org/) for further information.



These websites were opened in August of 2021.

The old documents are located at [GTK Reference Manual](https://developer-old.gnome.org/gtk4/stable/) and [GNOME Developer Center](https://developer-old.gnome.org/).



If you want to know about GObject and the type system, please refer to [GObject tutorial](https://github.com/ToshioCP/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](https://github.com/ToshioCP/Gtk4-tutorial/issues).

You can also post updated files to [pull request](https://github.com/ToshioCP/Gtk4-tutorial/pulls).

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.



#### How to get Gtk 4 tutorial with HTML or PDF format



If you want to get HTML or PDF format tutorial, make them with `rake` command, which is a ruby version of make.

Type `rake html` for HTML.

Type `rake pdf` for PDF.

There is a document \("[How to build GTK 4 Tutorial](gfm/Readme_for_developers.md)"\) for further information.
