ScalaFX is a UI DSL written within the Scala Language that sits on top of JavaFX. This means that every ScalaFX application is also a valid Scala application. By extension, it supports full interoperability with Java and can run anywhere the Java Virtual Machine (JVM) and JavaFX are supported.
If you have ScalaFX related questions please use ScalaFX Discussions, or ScalaFX Users Group, or ScalaFX on StackOverflow. Please report any problems using ScalaFX Issue Tracker.
ScalaFX binaries are published in the Maven Central repository: http://search.maven.org/#search|ga|1|scalafx
The official website for ScalaFX is http://scalafx.org.
ScalaFX 11+ is the current actively maintained version. ScalaFX 11+ is intended to support Java 11 and newer.
Here is how you can add dependency using SBT.
libraryDependencies += "org.scalafx" %% "scalafx" % "21.0.0-R32"Note that in ScalaFX version prior to 20.0.0-R31 and SBT older than 1.6, you needed to explicitly provide dependency on
JavaFX modules including platform dependent modules. This is no longer needed.
You can find examples of SBT setup in section Demo Projects and Examples below.
If you're using Mill:
object yourProject extends ScalaModule {
def scalaVersion = "3.0.0"
// Customize coursier resolution to discover the OS-specific artifacts required by JavaFX
// Note: this requires mill >= 0.9.7 (with pr/775 merged)
def resolutionCustomizer = T.task {
Some((r: coursier.core.Resolution) =>
r.withOsInfo(coursier.core.Activation.Os.fromProperties(sys.props.toMap))
)
}
// Add dependency on JavaFX libraries
val javaFXVersion = "16"
val scalaFXVersion = "16.0.0-R25"
val javaFXModules = List("base", "controls", "fxml", "graphics", "media", "swing", "web")
.map(m => ivy"org.openjfx:javafx-$m:$javaFXVersion")
def ivyDeps = {
Agg(
ivy"org.scalafx::scalafx:$scalaFXVersion",
//...
) ++ javaFXModules
}
}You can find sample ScalaFX Mill project here: scalafx-millproject
Example of build.gradle:
plugins {
id 'scala'
id 'application'
id 'org.openjfx.javafxplugin' version '0.0.13'
}
repositories {
mavenCentral()
}
javafx {
version = "21"
modules = ['javafx.controls', 'javafx.media']
}
dependencies {
implementation 'org.scala-lang:scala3-library_3:3.3.1'
implementation 'org.scalafx:scalafx_3:21.0.0-R32'
}
application {
mainClass = 'hello.ScalaFXHelloWorld'
}A complete sample Gradle project can ge found in ScalaFX-Hello-World-Gradle.
ScalaFX version number has two part. The first part corresponds to the latest JavaFX version it was tested with. The
second part is an incremental release number. For instance, version 15.0.1-R20 means that it was tested with JavaFX
version 15.0.1 and that is the 20th release of ScalaFX.
with Java 10 use:
libraryDependencies += "org.scalafx" %% "scalafx" % "10.0.2-R15"To use ScalaFX with SBT and Java 8 add following dependency (to use the latest scalafx you might need Java version at least 1.8.40):
libraryDependencies += "org.scalafx" %% "scalafx" % "8.0.192-R14"With Java 7 use:
libraryDependencies += "org.scalafx" %% "scalafx" % "2.2.76-R11"The ScalaFX Organization page on GitHub contains several sample project that illustrate use of ScalaFX. The simplest one, and recommended to start with, is scalafx-hello-world. There is also a Gradle version here: ScalaFX-Hello-World-Gradle.
Snapshot releases are also regularly published on Sonatype Snapshots. To use a snapshot build you may need to add "Sonatype OSS Snapshots" resolver to you SBT configuration:
resolvers += Opts.resolver.sonatypeSnapshotsIf you just want to download a recent snapshot build you can also use Travis CI build site https://travis-ci.org/scalafx/scalafx

The License text for this software can be found in LICENSE.txt in the root folder of the project.
The following software is needed to build ScalaFX:
- SBT v.1.6.0 or better
- Scala. ScalaFX 12 builds with Scala 2.10.2 or newer.
- Java 17 or better is required as of JavaFX 20 / ScalaFX 20.0.0-R31 (this is JavaFX 20 requirement
It works with Windows, Mac OS X, and Linux ports.
The current project directory structure:
./notes
./project
./scalafx
./scalafx-demos
Where . is the root folder of the project.
The notes folder contains release notes for past releases.
The scalafx folder is the sub-project for the ScalaFX Framework.
The scalafx-demos is the sub-project for the ScalaFX Framework Demonstrations, some are a bit out of date, help needed here :).
The project folder is reserved for SBT build system setup.
The current development is for ScalaFX 20.
The development is done on the master branch.
Releases are done on the stable branch.
Releases are tagged with version number.
Pull requests are only accepted off a branch created from the master branch.
When working on a pull request, create a separate branch for each feature or bug fix.
This way the main development branch is not blocked by a pull request and pull requests are easier to merge individually.
The ScalaFX 8 and 2.2 development is no longer active.
For those who need it, the code is on branches: SFX-8 and SFX-2.
Past releases are on SFX-8-stable and SFX-2-stable branches.
ScalaFX was originally created by Stephen Chin, Java Champion, Oracle JavaOne program chair; and Sven Reimers, a member of the Netbeans Dream Team.
The most up to date list of contributors to the project can be found on the Contributors page.
We request all the team members to follow the Typelevel Code of Conduct in our mailing list, issue discussion, Gitter room or any of ScalaFX meetups.
