An idiomatic GUI library inspired by Elm and based on gtk4-rs. Relm4 is a new version of relm that's built from scratch and is compatible with GTK4.

Goals

• ⏱️ Productivity: Writing an application should require as few overhead as possible
• ⚡ Flexibility: Anything that's possible to do with GTK4 should be possible in Relm4 as well
• ✨ Simplicity: Writing an application should be as easy and straight forward as possible
• 🔧 Maintainability: The Elm programming model used by Relm4 provides a simple and clear structure for app development

Documentation

• 📖 Book
• Rust documenation

Dependencies

Ecosystem

Relm4 has two crates that extend the core functionality:

• relm4-macros provides a widget macro that simplifies UI creation
• relm4-components is a collections of reusable components you can easily integrate into your application

Add this to your Cargo.toml:

toml gtk = { version = "0.2", package = "gtk4" } relm4 = "0.1.0-beta.2" relm4-macros = "0.1.0-beta.2" relm4-components = "0.1.0-beta.2"

Examples

Several example applications are available at relm4-examples/.
