Compose Multiplatform Desktop Application project template
APACHE-2.0 License
Note If you have any issues, please report them on GitHub.
Compose for Desktop can produce applications for macOS, Linux, and Windows. You can use any of these platforms with our template.
Follow our tutorial below to create a simple desktop application using the Compose Multiplatform UI framework.
If you want to create an application targeting mobile platforms – iOS and Android – use the Compose Multiplatform mobile application template.
Install the following tools:
Compose development can be simplified by adding support for the @Preview
annotation on argument-less @Composable
functions.
The plugin shows how a particular composable function looks in the IDE.
Starting with 2020.3, IntelliJ IDEA comes with a new project wizard that can automatically create a Compose for Desktop project.
Note When creating a project, select JDK 11 or later. To use the native distribution packaging, select JDK 15 or later.
Before you start, ensure that you’re using the latest version of the Compose Multiplatform IDE support plugin:
Check the latest release version in the Compose Multiplatform GitHub repository or on the Kotlin website.
Open the build.gradle.kts
file for your project and update the version:
plugins {
kotlin("jvm") version "1.9.0"
id("org.jetbrains.compose") version "1.5.0"
}
It is also possible to create a Compose project manually in the terminal.
We recommend building Compose for Desktop projects with Gradle. JetBrains provides a simple way of building such projects using a special Gradle plugin.
Note You can clone the existing template for a desktop or multiplatform application, or create one from scratch.
Create a new directory named sample
:
mkdir sample
cd sample
Create the settings.gradle.kts
file and modify it as follows:
pluginManagement {
repositories {
gradlePluginPortal()
maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")
}
}
Create the build.gradle.kts
file with the following content:
plugins {
kotlin("jvm") version "1.9.20"
id("org.jetbrains.compose") version "1.5.10"
}
repositories {
mavenCentral()
maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")
google()
}
dependencies {
implementation(compose.desktop.currentOs)
}
compose.desktop {
application {
mainClass = "MainKt"
}
}
Create src/main/kotlin/main.kt
and add the following code to it:
import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.material.Button
import androidx.compose.material.MaterialTheme
import androidx.compose.material.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp
import androidx.compose.ui.window.Window
import androidx.compose.ui.window.application
import androidx.compose.ui.window.rememberWindowState
fun main() = application {
Window(
onCloseRequest = ::exitApplication,
title = "Compose for Desktop",
state = rememberWindowState(width = 300.dp, height = 300.dp)
) {
val count = remember { mutableStateOf(0) }
MaterialTheme {
Column(Modifier.fillMaxSize(), Arrangement.spacedBy(5.dp)) {
Button(modifier = Modifier.align(Alignment.CenterHorizontally),
onClick = {
count.value++
}) {
Text(if (count.value == 0) "Hello World" else "Clicked ${count.value}!")
}
Button(modifier = Modifier.align(Alignment.CenterHorizontally),
onClick = {
count.value = 0
}) {
Text("Reset")
}
}
}
}
}
You can run and debug the application by clicking Run in the gutter near the main()
function declaration:
build.gradle.kts
. After the necessary dependencies from the Maven repositories are downloaded, your project will be ready.sample/Tasks/compose desktop/run
:The first run may take some time.
You can also run Gradle tasks in the terminal:
./gradlew run
to run the application./gradlew package
to store native distribution into build/compose/binaries
