conrod 0.21.6

An easy-to-use, immediate-mode, 2D GUI library

Conrod Build Status

An easy-to-use, 2D GUI library written entirely in Rust.

Here's a youtube demo of the example.

Here's another demo of it being used to create a basic synth editor.

You can find the API documentation here.

If you have an awesome looking GUI made with conrod, please send us a screenshot and we'll add it here :)

Current State

We're just starting to reach a stable-ish API pattern! There will still be some large changes however these are more likely to be new features than API overhauls.

To get a clearer idea of where we're at see the issues and in particular, the 1.0.0 milestone.


  • "Reactive"/"Immediate" style - produce the UI from your application state in one place, rather than as a separate entity spread across callbacks, instantiation, updates and drawing.
  • A simple Widget trait to allow for custom, third-party widgets.
  • Opt-in, generalised, easy-to-use scrolling! I.e. simply call .vertical_scrolling(true) on a widget and it will become a scrollable container for its children.
  • Powerful layout and positioning:
    • Placement - .middle(), .top_left_of(CANVAS), etc.
    • Alignment - .align_left(), .align_top_of(LABEL), etc.
    • Relative - .down(20.0), .right_from(BUTTON, 40.0), .relative_xy(20.0, 42.0), etc.
    • Absolute - .xy(6.0, 7.0)
    • Draggable pop-up / floating canvasses - .floating(true).
    • WidgetMatrix and PositionMatrix for instantiating a grid of widgets.
  • Serializable Themes for unique style and layout defaults.
  • widget_ids! macro for easily and safely generating unique widget identifiers.
  • Generic over events and graphics backends - compatible with glutin, sdl2, glium, gfx, opengl.
  • Comes with a collection of pre-made widgets.

Available Widgets


If conrod is missing anything you really wish it had, let us know with an issue describing the widget's style, behaviour and functionality - or even better, submit a pull request :D

Make sure you check the widget label for your desired widget first as it may have already been requested.

Getting Started

Get freetype - at the moment, Conrod uses freetype-rs for its font rendering, which means you'll need to have the freetype library installed on your system. You can download and install the freetype library here.

Build the conrod lib like this:

git clone
cd conrod
cargo build

And then build and run the examples like this:

cargo run --release --example all_widgets
cargo run --release --example canvas

You can add it to your project by adding this to your Cargo.toml:

conrod = "*"

Dependency Graph


Conrod uses Elmesque

Conrod uses Elmesque under the hood for its 2D graphics and layout. You don't need to know about Elmesque to use Conrod. But if you want to combine Conrod with your own custom Elmesque drawing, see the example.
