Description
In this talk we will look at declarative approaches to creating GUI applications, which could be said to have been popularized first by the Elm web programming language.
The first example will be a small GTK application called compare-fonts written in Haskell with the gi-gtk-declarative library.
The second part of the talk will look at some examples using Rust libraries like relm4, iced and vgtk.
The session will be a cross between demos with code and an interactive mini-tutorial in declarative GTK programming. If you want to follow along on your own laptop please checkout and build https://github.com/juhp/declarative-gtk-tutorial beforehand.

| Talk Description | The introduction will give some background to the origin of declarative GUI programming, which can be used for for web and desktop applications. The Elm language is close to Haskell, so the first example application will be compare-fonts which uses a declarative GTK layer over the gi-gtk bindings. The second half of the cover will discuss and showcase various declarative Rust gtk libraries. The technical interactive talk will give participants a feeling and understanding of the clear simplicity of declarative GUI programming. |
