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

Here's a youtube demo of the all_widgets.rs example.

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

You can find the API documentation here.

The all_widgets.rs example.

The canvas.rs example.

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

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), .mid_right_with_margin(20.0), etc.
  • Alignment - .align_left(), .align_top_of(LABEL), etc.
  • Relative - .down(20.0), .right_from(BUTTON, 40.0), .x_y_relative(20.0, 42.0), etc.
  • Absolute - .x_y(6.0, 7.0)
  • Draggable pop-up / floating canvasses - .floating(true).
  • WidgetMatrix and PositionMatrix for instantiating a grid of widgets.
• 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 and glfw Window backends.
  • gfx, glium and raw opengl Graphics backends.
• Comes with a collection of pre-made widgets.

• Shapes:
  • Circle
  • Rectangle
  • Oval
  • Polygon
  • FramedRectangle
• Line
• PointPath
• Text (automatic line-wrapping, line spacing, etc)

• Button
• Canvas (a container-like widget)
• DropDownList
• EnvelopeEditor
• WidgetMatrix
• NumberDialer
• Slider
• Tabs (for easily switching between multiple Canvasses with ease)
• TextBox
• TitleBar
• Toggle
• XYPad
• Custom: Conrod also provides a Widget trait for designing and implementing custom widgets. You can find an annotated demonstration of designing a custom widget implementation here. All internal widgets also use this same trait so they should make for decent examples. If you feel like your widget is useful enough to be included within the internal widget library, feel free to submit them in a pull request :)

To-do:

• Image (primitive widget)
• Menu Bar / Tool Bar
• Right-click Context Menu
• Multi-line Text Editor
• Graph / Chart
• File/Directory Navigator
• Advanced graph visualisation and control

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.

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 https://github.com/PistonDevelopers/conrod.git
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:

[dependencies]
conrod = "X.Y.Z"
