ScalaFX is a UI DSL written within the Scala Language that sits on top of JavaFX 2.x and and JavaFX 8. 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 2.0 or JavaFX 8 are supported.
Package Structure
ScalaFX package structure corresponds to JavaFX package structure, for instance
scalafx.animation
corresponds tojavafx.animation
.Example Usage
A basic ScalaFX application is created creating an object that is an instance of
JFXApp3
. Following Java FX theatre metaphor, it contains astage
that contains ascene
. Astage
roughly corresponds to a window in a typical UI environment. Thescene
holds UI content presented to the user. In the example below, the content is a pane with a singlelabel
component.
