Hello ImGui,

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

It's still a work in progress.

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

1. Clone ImGui

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

2. 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>

3. 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!");
   });

4. Build your project

5. Run

   • run with Visual Studio 2022: Press F5
   • run on Windows/Linux:

     cd MyImGuiApp
     dotnet MyApp.dll
     

6. Exit

   Press Esc or click the close button of the window.

Android

1. Copy Android Templates project. Referenced shared project Demo can be removed if not needed.
2. Add your GUI code in MainForm.OnGUI.
3. Build and deploy it to your Android device.

Documentation

For now, please refer to the shared project Demo for how to use Hello ImGui.

Dependency
