Gtk4 Tutorial for beginners

Contents of this repository

This tutorial illustrates how to write C programs with Gtk4 library. It focuses on beginners so the contents are limited to basic things. The table of contents are shown at the end of this abstract.

• Section 3 to 21 describes basics and the example is a simple editor tfe (Text File Editor).
• Section 22 to 24 describes GtkDrawingArea.
• Section 25 to 28 describes list model and list view (GtkListView, GtkGridView and GtkColumnView). It also describes GtkExpression.

The latest version of the tutorial is located at Gtk4-tutorial github repository. You can read it without download.

Gtk4 Documentation

Please refer to Gtk API Reference and Gnome Developer Documentation Website for further topics.

These websites are newly opend lately (Aug/2021). The old documentation is located at Gtk Reference Manual and Gnome Developer Center. The new website is in progress at present, so you might need to refer to the old version.

If you want to know about GObject and type system, refer to GObject tutorial. They are basic and also necessary to write Gtk4 programs.

Contribution

This tutorial is under development and unstable. Even though the codes of the examples have been tested on Gtk4 version 4.0, there might exist bugs. 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 corrected files as a commit to pull request. When you make corrections, correct the source files, which are under the 'src' directory. And run rake, then GFM files under the 'gfm' directory are automatically updated.

If you have a question, feel free to post it to the issue. Any question is helpful to make this tutorial get better.

How to get a HTML or PDF version

If you want to get a HTML or PDF version, you can make them with rake, which is a ruby version of make. Type rake html for HTML. Type rake pdf for PDF. There is a documentation ("How to build Gtk4 Tutorial") that describes how to make them.
