ScalaFX 8.0.40-SNAPSHOT + Spinner

Upcoming release of JavaFX 8u40 will bring several enhancements, including dialogs and new spinner control. ScalaFX started new branch, SFX8u40, to support JavaFX 8u40. One of the first things added is Spinner. A spinner is a single line text field that lets the user select a number or an object value from an ordered sequence. There are predefined Spinner classes for holding values of Integer, Double, and List of arbitrary values.

Here is a sample ScalaFX code that generates above Spinners for Integers, Doubles, and lists of Strings

import scalafx.application.JFXApp
import scalafx.application.JFXApp.PrimaryStage
import scalafx.collections.ObservableBuffer
import scalafx.geometry.Insets
import scalafx.scene.Scene
import scalafx.scene.control.Spinner
import scalafx.scene.layout.{HBox, VBox}

/**
 * A sample that demonstrates the Spinner control.
 */
object SpinnersDemo extends JFXApp {

  val styles = Seq(
    "spinner", // defaults to arrows on right stacked vertically
    Spinner.StyleClassArrowsOnRightHorizontal,
    Spinner.StyleClassArrowsOnLeftVertical,
    Spinner.StyleClassArrowsOnLeftHorizontal,
    Spinner.StyleClassSplitArrowsVertical,
    Spinner.StyleClassSplitArrowsHorizontal
  )

  val intSpinners = for (s <- styles) yield
    new Spinner[Integer](1, 99, 5) {
      styleClass += s
      prefWidth = 100
    }

  val stringSpinners = for (s <- styles) yield
    new Spinner[String](ObservableBuffer("Grace", "Matt", "Katie")) {
      styleClass += s
      prefWidth = 100
    }

  val doubleSpinners = for (s <- styles) yield
    new Spinner[Double](0.0, 1.0, 0.5, 0.01) {
      styleClass += s
      prefWidth = 100
    }

  stage = new PrimaryStage {
    title = "Spinners Demo"
    scene = new Scene {
      content = new VBox(30) {
        content = Seq(
          new HBox(30, intSpinners: _*),
          new HBox(30, doubleSpinners: _*),
          new HBox(30, stringSpinners: _*)
        )
        padding = Insets(24)
      }
    }
  }
}

To take a SNAPSHOT for a spin add following to your SBT build file:

libraryDependencies += "org.scalafx" %% "scalafx" % “8.0.40-SNAPSHOT”
