Eto.Forms

A cross platform desktop and mobile user interface framework

Description

This framework can be used to build applications that run across multiple platforms using their native toolkit, with an easy to use API. This will make your applications look and work as a native application on all platforms, using a single UI codebase.

For advanced scenarios, you can take advantage of each platform's capabilities by wrapping your common UI in a larger application, or even create your own high-level controls with a custom implementations per platform.

This framework currently supports creating Desktop applications that work across Windows Forms, WPF, Cocoa, and GTK#. There is a Mobile/iOS port in the works, but is considered incomplete.

This framework was built so that using it in .NET is natural. For example, a simple hello-world application might look like:

using Eto.Forms;
using Eto.Drawing;

public class MyForm : Form
{
	public MyForm ()
	{
		Title = "My Cross-Platform App";
		ClientSize = new Size(200, 200);
		Content = new Label { Text = "Hello World!" };
	}

	[STAThread]
	static void Main()
	{
		new Application().Run(new MyForm());
	}
}

or in a F# script:

#load ".paket/load/eto.platform.windows.fsx"
// see https://fsprojects.github.io/Paket/paket-generate-load-scripts.html

open Eto.Drawing
open Eto.Forms

type MyForm() as this =
    inherit Form()
    do
        this.Title      <- "My Cross-Platform App"
        this.ClientSize <- Size (200, 200)
        this.Content    <- new Label(Text = "Hello F# World!")

Eto.Platform.Initialize(Eto.Platforms.WinForms)
let app = new Application()
let form = new MyForm()
form.Show()
