Relm4 icons - Icons for your Relm4 and gtk-rs applications!

CI Matrix Relm4 icons on crates.io Relm4 icons docs Minimum Rust version 1.65 dependency status

More than 2500 icons, ready for use in your app!


1. Find your icons 🔍

Use one of the following methods:

For icons from the GNOME icon-development-kit:

For icons from Fluent UI System Icons:

For browsing all icons:

2. Get relm4-icons ✍

For each icon you want to use, you can add a feature flag. Only the icons you specify will be compiled into your application.

relm4-icons = { version = "0.7.0", features = ["<icon1>", "<icon2>", "<icon3>..."] }


To enable the plus and minus icons use:

relm4-icons = { version = "0.6.1", features = ["plus", "minus"] }

The file ending -symbolic.svg isn't part of the icon name.

3. Load the icons 🛫

Add this somewhere in your initialization code (after initializing RelmApp or GTK).


4. Use the icons 🎉

Use set_icon_name and similar methods to use your icons, for example with ButtonExt, StackPage, MenuButton or Image.


let button = gtk::Button::default();

You can also use the icon_name module for extra compile-time checking of icon names.

use relm4_icons::icon_name;

let button = gtk::Button::default();

How it works


  1. Find all icons in the icons folder
  2. Generate a feature flag and a conditional constant for each icon


  1. Include only the selected icons in a gresource file
  2. Include the gresource file in the compiled binary
  3. On initialization, add the gresource file to the default icon theme

Add new icons

To add new icons, move them into the icons folder and make sure their file name ends with -symbolic.svg. Then run the following commands:

cd update_icons
cargo run


  • GNOME contributors for providing so many outstanding icons
  • gvdb-rs for providing a great crate for interacting with gresources in pure Rust
  • gtk-rs for outstanding Rust bindings for GTK4
