Compose Multiplatform example project?

I’d like to create a new Processing project using Compose Multiplatform.

Is there an example project or a starter project that would show me how to get started on one?

We don’t have an example project yet, but my Kotlin template could be a good starting point: GitHub - Stefterv/processing4-kotlin: A minimal example on how to run Processing within Kotlin

The Processing DE also uses Compose Multiplatform so that could be an inspiration.

github.com/processing/processing4

app/build.gradle.kts

main

import org.gradle.internal.jvm.Jvm
import org.gradle.internal.os.OperatingSystem
import org.gradle.nativeplatform.platform.internal.DefaultNativePlatform
import org.jetbrains.compose.desktop.application.dsl.TargetFormat
import org.jetbrains.compose.desktop.application.tasks.AbstractJPackageTask
import org.jetbrains.compose.internal.de.undercouch.gradle.tasks.download.Download
import java.io.FileOutputStream
import java.util.zip.ZipEntry
import java.util.zip.ZipOutputStream

// TODO: Update to 2.10.20 and add hot-reloading: https://github.com/JetBrains/compose-hot-reload

plugins{
    id("java")
    kotlin("jvm") version libs.versions.kotlin

    alias(libs.plugins.compose.compiler)
    alias(libs.plugins.jetbrainsCompose)
    alias(libs.plugins.serialization)
    alias(libs.plugins.download)

The only thing I have not tried yet is to see if I can hook a Compose frame into the Processing window, but my intuition would says it could be possible.
