Kotlin/Native bindings and window helpers for Dear ImGui on desktop.

imgui2kt provides:

• a generated Kotlin facade for the cimgui Dear ImGui API
• a simple GLFW desktop window host
• click-through and interactive overlay hosts
• Linux linuxX64 and Windows mingwX64 targets

Add the plugin from Maven Central:

// settings.gradle.kts
pluginManagement {
    repositories {
        gradlePluginPortal()
        mavenCentral()
    }
}

dependencyResolutionManagement {
    repositories { mavenCentral() }
}

// build.gradle.kts
plugins {
    kotlin("multiplatform") version "2.3.20"
    id("org.kvxd.imgui2kt.runtime") version "0.7.0"
}

kotlin {
    linuxX64 {
        binaries.executable {
            entryPoint = "example.main"
        }
    }
}

Then create src/nativeMain/kotlin/example/Main.kt:

package example

import org.kvxd.imgui2kt.ImGui
import org.kvxd.imgui2kt.desktopWindow

fun main() {
    desktopWindow(title = "imgui2kt", width = 900, height = 560) { window ->
        window.run {
            ImGui.window("Hello") {
                ImGui.textUnformatted("Dear ImGui from Kotlin/Native")
            }
        }
    }
}

Build it:

./gradlew linkDebugExecutableLinuxX64

Run an example from this repository:

./gradlew :examples:simple-window:linkDebugExecutableLinuxX64

To build the Windows executable from Linux:

./gradlew :examples:simple-window:linkDebugExecutableMingwX64

• examples/simple-window: normal desktop window
• examples/simple-overlay: click-through HUD overlay
• examples/interactive-overlay: overlay that can switch between HUD and interactive input

Linux builds require:

• CMake
• C and C++ compilers
• OpenGL development files
• Wayland development files
• EGL
• xkbcommon
• pkg-config
• wayland-scanner

Windows target builds use Kotlin/Native mingwX64. Cross-building from Linux also requires:

• x86_64-w64-mingw32-gcc
• x86_64-w64-mingw32-g++
• x86_64-w64-mingw32-windres

Publish the library and Gradle plugin to Maven Local:

./gradlew publishAllToMavenLocal

Publish the library and Gradle plugin to Maven Central:

./gradlew publishAllToMavenCentral

Maven Central publishing requires the Vanniktech Maven Publish credentials and signing properties to be available to Gradle. The release version is set in gradle.properties as imgui2kt.version.
