gtk4-rs: GTK 4 Rust Bindings Final Report

This is the final report on GTK 4 Rust Bindings. You can find project links and repositories on the about page.

Describe my work briefly

• Add Rust support to the gtk4 toolkit, including
  • gtk4
  • gsk4
  • gdk4
  • graphene
• Port gtk3 Rust examples to gtk4.

What is done

• gtk4-rs: https://github.com/gtk-rs/gtk4

The is the main API for gtk4 software development. Changes in gtk4 are reflected here, including new layout managers, deprecation of child properties, and new/removed widgets.

• gsk4-rs: https://github.com/gtk-rs/gsk4

The new GTK Scene Kit API callable from Rust, featuring the extensive render nodes type system highlighted in previous posts.

• gdk4-rs: https://github.com/gtk-rs/gdk4

gdk4 has undergone a lot of changes since its last version, with refined interaction between gtk. It’s overhauled event system was specially bound in Rust too.

• graphene-rs: https://github.com/gtk-rs/graphene
• examples: https://github.com/sfanxiang/gtk-rs-examples4 (will be upstreamed)
• Low-level, unsafe bindings: https://github.com/gtk-rs/sys/pull/145
• Automatic creation of gtk4 dependency bundle: https://github.com/sfanxiang/gtk-bootstrap

Future work

• Improve Rust-specific documentation in https://github.com/gtk-rs/lgpl-docs.
• More bindings. There’s always more we can do.
• CI support for OSX and Windows.
