Hello ImGui,

Hello ImGui is an immediate mode GUI library inspired by IMGUI of Unity3D and dear imgui.

Now it runs on Win10, Linux(Ubuntu 16.04) and Android. See platforms. Mac and iPhone are not supported because I don't have them.

Get Started

Windows and Linux

Clone ImGui

git clone https://github.com/zwcloud/ImGui.git

Create a .NET7 console project and reference ImGui.

mkdir MyImGuiApp

Create MyImGuiApp.csproj with following content:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>exe</OutputType>
    <TargetFramework>net7.0</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <ProjectReference Include=".\ImGui\src\ImGui\ImGui.csproj" />
  </ItemGroup>
</Project>

Add Program.cs to your project,

using ImGui;
var demo = new Demo();
Application.Run(new Form(new Rect(320, 180, 1280, 720)), () =>
{
    demo.OnGUI();
    ImGui.GUILayout.Label("Hello, ImGui!");
});
