    ScalaFX is a UI DSL written within the Scala Language that sits on top of JavaFX 2.x and and JavaFX 8.

    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 to javafx.animation.

    Example Usage

    A basic ScalaFX application is created creating an object that is an instance of JFXApp. Following Java FX theatre metaphor, it contains a stage that contains a scene. A stage roughly corresponds to a window in a typical UI environment. The scene holds UI content presented to the user. In the example below, the content is a pane with a single label component.

    package hello

import scalafx.application.JFXApp
import scalafx.application.JFXApp.PrimaryStage
import scalafx.geometry.Insets
import scalafx.scene.Scene
import scalafx.scene.control.Label
import scalafx.scene.layout.BorderPane

object HelloWorld extends JFXApp {
  stage = new PrimaryStage {
    title = "Hello"
    scene = new Scene {
      root = new BorderPane {
        padding = Insets(25)
        center = new Label("Hello World")
      }
    }
  }
}

Type Members

  1. trait EventHandled extends AnyRef

    Trait used for handle events manipulation.

    Trait used for handle events manipulation. JavaFX class wrapped must have methods defined in scalafx.event.EventHandlerDelegate2.EventHandled Type:

    def addEventHandler   [E <: jfxe.Event](eventType: jfxe.EventType[E], eventHandler: jfxe.EventHandler[_ >: E])
def removeEventHandler[E <: jfxe.Event](eventType: jfxe.EventType[E], eventHandler: jfxe.EventHandler[_ >: E])
def addEventFilter    [E <: jfxe.Event](eventType: jfxe.EventType[E], eventHandler: jfxe.EventHandler[_ >: E])
def removeEventFilter [E <: jfxe.Event](eventType: jfxe.EventType[E], eventHandler: jfxe.EventHandler[_ >: E])
def buildEventDispatchChain(chain: jfxe.EventDispatchChain): jfxe.EventDispatchChain
  2. sealed trait FilterMagnet[J <: javafx.event.Event, S <: SFXDelegate[J]] extends AnyRef

    Trait implementing Magnet Pattern to avoid compilation error "ambiguous reference to overloaded definition"

  3. sealed trait HandlerMagnet[J <: javafx.event.Event, S <: SFXDelegate[J]] extends AnyRef

    Trait implementing Magnet Pattern to avoid compilation error "ambiguous reference to overloaded definition"

Abstract Value Members

  1. abstract def eventHandlerDelegate: EventHandled

    Returns a object that implements scalafx.event.EventHandlerDelegate2.EventHandled.

  4. def addEventFilter[E <: javafx.event.Event](eventType: javafx.event.EventType[E], eventHandler: EventHandler[_ >: E]): Unit

    Registers an event filter to this task.

    Registers an event filter to this task. Registered event filters get an event before any associated event handlers.

    E

    Event class

    eventType

    the type of the events to receive by the filter

    eventHandler

    the filter to register that will filter event

  5. def addEventHandler[E <: javafx.event.Event](eventType: javafx.event.EventType[E], eventHandler: EventHandler[_ >: E]): Unit

    Registers an event handler to this task.

    Registers an event handler to this task. Any event filters are first processed, then the specified onFoo event handlers, and finally any event handlers registered by this method. As with other events in the scene graph, if an event is consumed, it will not continue dispatching.

    E

    Event class

    eventType

    the type of the events to receive by the handler

    eventHandler

    the handler to register that will manipulate event

    Example of filtering mouse events

    pane.filterEvent(MouseEvent.Any) {
  me: MouseEvent => {
    me.eventType match {
      case MouseEvent.MousePressed => {
        ...
      }

      }
      case _ => {
        ...
