trait JFXApp3 extends AnyRef
ScalaFX applications can extend JFXApp3 to create properly initialized JavaFX applications.
On the back end JFXApp3
first calls javafx.application.Application.launch then executes body of its
constructor when
javafx.application.Application.start(primaryStage:Stage)
is called. Here is an example use:
object SimpleScalaFXApp extends JFXApp3 { override def start() : Unit = { stage = new PrimaryStage { title = "Simple ScalaFX App" scene = new Scene { root = new StackPane { padding = Insets(20) content = new Rectangle { width = 200 height = 200 fill = Color.DEEPSKYBLUE } } } } } }

JFXApp3 stage must be an instance of scalafx.application.JFXApp3.PrimaryStage to ensure that it actually is a proper wrapper for the primary stage supplied by JavaFX.
- def stopApp(): Unit
This method is called when the application should stop, and provides a convenient place to prepare for application exit and destroy resources.
This method is called when the application should stop, and provides a convenient place to prepare for application exit and destroy resources.
It is called from javafx.Application.stop method. The implementation of this method provided by the JFXApp3 class does nothing.
NOTE: This method is called on the JavaFX Application Thread, the same as javafx.Application.stop method.

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.
