Gtk4-tutorial/src/abstract.src.md

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 20 describes basics and the example is a simple editor `tfe` (Text File Editor).
- Section 21 to 23 describes GtkDrawingArea.
- Section 24 to 27 describes list model and list view (GtkListView, GtkGridView and GtkColumnView).
It also describes GtkExpression.

Please refer to [Gtk reference manual](https://developer.gnome.org/gtk4/stable/index.html)

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.
