gdx-imgui

gdx-imgui is a java binding for C++ dear-imgui.
It uses webidl file to generate java methods with the help of jParser.
It's meant to be small and 1-1 to C++. ImGui::Begin() is ImGui.Begin() and so on.

Examples

How to run examples

There are two ways to run examples.

• Build the source and run: ./gradlew :examples:basic:desktop:basic-run-desktop
• Change LibExt.exampleUseRepoLibs to true in Dependencies.kt and that will make all examples use snapshot from repository

Setup

gdxVersion = "1.12.1"
gdxImguiVersion = "-SNAPSHOT"

// Add repository to Root gradle
repositories {
    mavenLocal()
    mavenCentral()
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
    maven { url "https://oss.sonatype.org/content/repositories/releases/" }
}

dependencies {
    // Required implementation
    implementation "com.github.xpenatan.gdx-imgui:gdx-impl:$project.gdxImguiVersion"
    
    // ImGui only
    implementation "com.github.xpenatan.gdx-imgui:imgui-core:$project.gdxImguiVersion"
    
    // ImGui only platform natives
    implementation "com.github.xpenatan.gdx-imgui:imgui-desktop:$project.gdxImguiVersion"
    //implementation "com.github.xpenatan.gdx-imgui:imgui-android:$project.gdxImguiVersion"
    //implementation "com.github.xpenatan.gdx-imgui:imgui-ios:$project.gdxImguiVersion"
    implementation "com.github.xpenatan.gdx-imgui:imgui-teavm:$project.gdxImguiVersion"

    // ImGui with extensions
    implementation "com.github.xpenatan.gdx-imgui:imgui-ext-core:$project.gdxImguiVersion"
    
    // ImGui with extensions platform natives
    implementation "com.github.xpenatan.gdx-imgui:imgui-ext-desktop:$project.gdxImguiVersion"
    //implementation "com.github.xpenatan.gdx-imgui:imgui-ext-android:$project.gdxImguiVersion"
    //implementation "com.github.xpenatan.gdx-imgui:imgui-ext-ios:$project.gdxImguiVersion"
    implementation "com.github.xpenatan.gdx-imgui:imgui-ext-teavm:$project.gdxImguiVersion"
}

Build source

• Requirements: Java 11, mingw64 and emscripten
• Windows only for now.

##### ImGui
./gradlew :imgui:imgui-build:download_source
./gradlew :imgui:imgui-build:build_project

##### ImGui with extensions. Need to build ImGui first
./gradlew :extensions:imlayout:imlayout-build:build_project
./gradlew :extensions:ImGuiColorTextEdit:textedit-build:download_source
./gradlew :extensions:ImGuiColorTextEdit:textedit-build:build_project
./gradlew :extensions:imgui-node-editor:nodeeditor-build:download_source
./gradlew :extensions:imgui-node-editor:nodeeditor-build:build_project
./gradlew :imgui:imgui-ext-build:build_project
