ScalaFX v.1.0 Milestone 3 Released

[Jarek Sacha]

The third milestone of ScalaFX v.1.0 is now available on our Downloads page and in the Maven repository.

ScalaFX helps you simplify creation of JavaFX-based user interfaces in Scala. ScalaFX uses a simple, hierarchical pattern for creating new objects and building up the scene graph. ScalaFX supports full interoperability with Java and can run anywhere the Java Virtual Machine (JVM) and JavaFX2 are supported. Current version supports most of the JavaFX 2.2.7 functionality. For more information see ScalaFX home page.

Changes since Milestone 2

• Improvements to handling of collections within ScalaFX code  For instance, utility functions added to help filling collections and deal with `null` passed from the user.
• Improvements to scaladocs.
• Missing methods added to `Scene`: `fill`, ` addMnemonic`, ` removeMnemonic`, ` getMnemonics`, ` accelerators`, ` snapshot`, ` startDragAndDrop`, ` startFullDrag`.
• Additional `Font` factory methods.
• Fixed Issue 39: scalafx.scene.control.Pagination PageFactory is not working
• Fixed Issue 45: Missing wrappers for ReadOnly[Boolean,Double,Float,Integer,Long,String]Wrappers
• Fixed Issue 57: `Control` should extend `Parent` not `Node`.
• Work around for Scala 2.10 bug SI-7269 that was causing one of the test in ObservableMapSpec to fail. Please add your votes for the fix.
• Added some factory methods for `ReadOnlyObjectWrapper` as a workaround for Issue 14.
• Sbt-idea updated to v.1.3.0 for improved IDEA project generation.

A big thank you to all the contributors!

Is there a Maven Archetype somewhere we can use with this?

Cheers, Eric

If not, here's a pom file to get you started at https://gist.github.com/hohonuuli/3940257 

It's getting a little old so you'll have to change a few of the dependency versions, but it should get you going.

Thanks for the reference, but reviewing 221 lines of POM just makes my eyes glaze over.

As much as I REALLY want to do stuff with ScalaFX, the onboarding cost is WAY too high. There STILL does not seem to be any simple way to just get going with ScalaFX in 5 minutes.

One of the things I have learned over decades of trying to sell innovation to people, is that people generally try what is easy to try, and give up on stuff that seems too hard.

I simply do not have more than 1 hour to spend fussing with ScalaFX. I am trying to follow http://code.google.com/p/scalafx/wiki/GettingStarted

Currently I am stuck with

Description    Resource    Path    Location    Type
bad symbolic reference. A signature in Stage.class refers to term javafx in package <root> which is not available. It may be completely missing from the current classpath, or the version on the classpath might be incompatible with the version used when compiling Stage.class.    client        Unknown    Scala Problem

I am using the ScalaIDE from TypeSafe with

    <dependency>
        <groupId>org.scalafx</groupId>
        <artifactId>scalafx_2.10</artifactId>
        <version>1.0.0-M3</version>
    </dependency>

And have everything I can find set to the latest version of Java 7.

Cheers, Eric

Ummm ... you're welcome?

I did not mean to seem ungrateful, but I want this to be easy for everyone to do, not just me.

I really am grateful, and will probably look at it closer when I have more free time to spend.

Cheers, Eric

Just give a try at GroovyFX or JavaFX itself... They might be simpler to board on.

Since the release of the recent milestones, this page is highly outdated. But I still did not had time to tweak it.

 

Currently I am stuck with

Classic missing JavaFX lib from your classpath. JavaFX is delivered with the JRE, yet its jar is NOT on the standard classpath. Add it manually.

Hope this might help keep you trying in spite of the steady learning curve.

Alain

Yes, that is a classic screw-up on the part of Oracle. I added jfxrt.jar to my classpath and it fixes that problem. Thanks muchly :-)

I now remember encountering this problem before with JavaFX. My sense is that Oracle do not consider JavaFX important enough to support properly. Hopefully this will be fixed in Java 8.

An automated way to fix this problem would be to use Maven, put jfxrt.jar in Maven Central, and make jfxrt.jar a transitive dependency. My sense is that all of this could be automated by a properly defined ScalaFX archetype for Maven. Automation is almost always better than documentation.

Hope this might help keep you trying in spite of the steady learning curve.

Thanks that helps enormously. Now the next problem I am having is

Description    Resource    Path    Location    Type

type mismatch;  found   : scalafx.scene.shape.Rectangle  required: scalafx.scene.Parent    App.scala    /client/src/main/scala/net/kolotyluk/find_duplicate_files/client    line 27    Scala Problem


import scalafx.Includes._
import scalafx.application.JFXApp
import scalafx.scene.Scene
import scalafx.scene.paint.Color
import scalafx.scene.shape.Rectangle
import scalafx.stage.Stage

object App extends JFXApp {
  stage = new JFXApp.PrimaryStage {
    title = "Hello World"
    width = 600
    height = 450
    scene = new Scene {
      fill = Color.LIGHTGREEN
      root = new Rectangle { // line 27
        x = 25
        y = 40
        width = 100
        height = 100
        fill <== when(hover) then Color.GREEN otherwise Color.RED
      }
    }
  }
}

Am I using the most recent example of the Hello World program?

Cheers, Eric

Regards,

Alain

[Eric Kolotyluk]

Does there exist anywhere a working example of Hello World in ScalaFX?

I tried the version from http://code.google.com/p/scalafx/wiki/GettingStarted

package hello

import scalafx.Includes._
import scalafx.application.JFXApp
import scalafx.scene.Scene
import scalafx.scene.paint.Color
import scalafx.scene.shape.Rectangle
import scalafx.stage.Stage

object World extends JFXApp {

  stage = new JFXApp.PrimaryStage {
    title = "Hello World"
    width = 600
    height = 450
    scene = new Scene {
      fill = Color.

LIGHTGREEN
      root = new Rectangle { // line 28
        x = 25

        y = 40
        width = 100
        height = 100
        fill <== when(hover) then Color.GREEN otherwise Color.RED
      }
    }
  }
}

but according to the Scala IDE from Typesafe

Description    Resource    Path    Location    Type

type mismatch;  found   : scalafx.scene.shape.Rectangle  required: scalafx.scene.Parent    App.scala    /client/src/main/scala/net/kolotyluk/find_duplicate_files/client    line 28    Scala Problem

[Eric Kolotyluk]

OK, problem solved

Listing of the `hello/World.scala` application object is wrong!

root = new Rectangle {

should be

content = new Rectangle {

Cheers, Eric
