ImGuinZ

This project aims to simply and easily build Dear ImGui (CImGui) / ImPlot (CImPlot), Raylib, rlImGui and many other libaries and examples in Zig with less external dependencies.

• ImGui / CImGui version 1.92.6 dock (2026/02)

• OS: Windows11 and Linux

• Frontends and Backends

  | | GLFW | SDL3 | Win32 | | --- | :----: | :----: | :----: | OpenGL3<br>backend | YES | YES | - | SDLGPU3<br>backend | - | YES | - | DirectX 11<br>backend | - | - | YES

• Features

  • Included Font Awesome Icon fonts.
    
  • Included GLFW 3.4.0 static library (for Windows)
  • Included SDL3.4.x libraries (for Windows)
  • Included STB libraries (only stb_image) for Load / Save images
  • Available ImPlot (CImPlot) / ImPlot3D with ImDrawIdx="unsigned int"
  • Enabled Input method (IME) flag with IMGUI_ENABLE_WIN32_DEFAULT_IME_FUNCTIONS

Zig fetch

---

1. Zig fetch imguinz

   mkdir myapp
   cd myapp
   zig init
   
   zig fetch --save git+https://github.com/dinau/imguinz
   

2. Add dependencies to build.zig

   const imguinz = b.dependency("imguinz", .{});
   const dependencies = .{
       "appimgui",      // Simple app framework
       "imspinner",     // ImSpinner
       "imknobs",       // ImKnobs
       "imtoggle",      // ImToggle
    // "another_lib",
   };
   inline for (dependencies) |dep_name| {
       const dep = imguinz.builder.dependency(dep_name, .{
           .target = target, 
           .optimize = optimize, 
       });
       exe.root_module.addImport(dep_name, dep.module(dep_name));
   }
   exe.subsystem = .Windows; // Hide console window
   

   You can set dependencies (additional libraries), see imguinz/build.zig.zon

   "appimgui"     <- Simple app framework for GLFW and OpenGL backend
   "imspinner"    <- ImSpinner
   "imguizmo"     <- ImGuizmo
   "imknobs"      <- ImKnobs 
   "imnodes"      <- ImNodes
   "implot"       <- ImPlot
   "implot3d"     <- ImPlot3D
   "imtoggle"     <- ImToggle
   "rlimgui"      <- rlImgui
   ... snip  ...
   

3. Edit src/main.zig

   const app = @import("appimgui");
   const ig = app.ig;
   const spinner = @import("imspinner");
   const knobs = @import("imknobs");
   const tgl = @import("imtoggle"); // ImToggle
   
   // gui_main()
   pub fn gui_main(window: *app.Window) void {
       var col: f32 = 1.0;
       var fspd: bool = false;
       var speed: f32 = 2.0;
       var spn_col: spinner.ImColor = .{ .Value = .{ .x = col, .y = 1.0, .z = 1.0, .w = 1.0 } };
       while (!window.shouldClose()) { // main loop
           window.pollEvents();
           window.frame(); // Start ImGui frame
   
           ig.igShowDemoWindow(null); // Show demo window
                                      //
           ig.igSetNextWindowSize(.{ .x = 0.0, .y = 0.0 }, 0); // Fit window size depending on the size of the widgets
           _ = ig.igBegin("imguinz", null, 0); // Show Spinner window
           spinner.SpinnerAtomEx("atom", 16, 2, spn_col, speed, 3);
           ig.igSameLine(0.0, -1.0);
           _ = tgl.Toggle("Speed", &fspd, .{ .x = 0.0, .y = 0.0 });
           if (fspd) speed = 6.0 else speed = 2.0;
           if (knobs.IgKnobFloat("Color", &col, -1.0, 1.0, 0.1, "%.1f", knobs.IgKnobVariant_Stepped, 0, 0, 10, -1, -1)) {
               spn_col.Value.x = col;
           }
           ig.igEnd();
   
           window.render(); // render
       } // end while loop
   }
   
   pub fn main() !void {
       var window = try app.Window.createImGui(1024, 900, "ImGui window in Zig");
       defer window.destroyImGui();
   
       _ = app.setTheme(.dark); // Theme: dark, classic, light, microsoft
   
       gui_main(&window); // GUI main proc
   }
