jrubyfx's Introduction

JRubyFX

JRubyFX is a pure ruby wrapper for JavaFX 2.2+ with FXML support. Currently supported: Java 8+, JRuby 9.3+.

Status

JRubyFX master should be usable in its current form and able to run most FXML apps. As of JRubyFX 2.0, the Java FXML Loader is used. This requires JRuby 9.3+. Please see the JRubyFX github wiki for upgrading from 1.x.

Install

For JRuby 9.3.4+:

gem install jrubyfx

For older JRuby versions:

gem install jrubyfx -v 1.2

If you are using Java 9+, additionally append the contents of module-opens.txt to bin/.jruby.java_opts in your jruby install. If you fail to do this, you may get inscruitable "method X not found, did you mean X?" errors.

Manual Build and Install

Build is done using rake/gem/bundler/rdoc. You need JRuby >= 9.3.4.0, Java >= 8 with JavaFX 11 modules installed (only required for reflect task). Building native application packages requires JDK 8+.

rake install

Once the gem is installed, just run a ruby file that uses it normally.

NOTE: If you don't have JRuby installed as the ruby command, use jruby -S rake instead of rake. If you are using RVM, this does not apply to you (though make sure you rvm use jruby).

If you are reporting bugs or encountering fxml issues: please ensure you are using JRubyFX 2.0. Prior version relied on a ported fxml parser and had many known issues.

Updating the Imports

JRubyFX currently uses the 11-based classes for the default imports (part_imports.rb). In the future, this list may change. See gen_tree.rb for a script to help automate finding the classes to import.

Creating a Jar

If you want to distribute your application, you can create a jar with embedded JRuby. Place all your sources in a folder, and run (replacing paths as appropriate):

jrubyfx-jarify samples/fxml/ --main samples/fxml/Demo.rb Demo.jar

This jar can then run anywhere there is a JVM with JavaFX. Note than the main file is renamed to jar-bootstrap.rb inside the jar. If you need to detect if you are in a jar, use the JRubyFX::Application.in_jar? method.

You can create native application packages and installers. For now, this requires that you have JDK8 installed, although this may change in the near future. Just pass the --native option. The packaging toolkit can only create packages for the OS it is being used on, so for Windows installers you will need to run it on a Windows machine, for OSX installers you will need to run it on a Mac, etc.

In order for the installer to be created, you will need some additional tools installed on your system. For Windows you need either Inno Setup 5 or later for an EXE or Windows Installer XML (WiX) toolset to generate an MSI. Make sure the WiX toolset's bin folder is on the PATH. No special tools are need to generate a DMG, just a recent version of OSX. For linux, the packager uses dpkg-deb to create DEB installers and rpmbuild for RPM.

If you don't want your application to be called "JarBootstrapMain", I highly suggest passing the --name option with an appropriate string.

To customize the package, for example to change the icons or license pass the -v or --verbose option. This will cause the JavaFX packaging tools to enter verbose mode, and provide more details about the process, including (the important part for customization) the location of a temporary folder where the config resources for the build are held and a list of the resources and the role of each. Copy the contents of this tmp folder into a folder in your project directory (the dir you run jrubyfx-jarify from) where the packaging tools will know to look for them. For example, on linux this would be main_project_dir/package/linux. On OSX, it is main_project_dir/package/macosx. So, if I wanted to use a custom icon, I'd replace the default icon with my own, ensuring it has the same name, and place it inside that linux or macosx folder. Then run the build again. You can find more information on customizing at the official Oracle documentation. This blog post may also be helpful, as he goes through the process of customizing an app for both Windows and OSX.

The JavaFX tools provide far more options than are available from this tool. You can create your own rake tasks and access them directly, however. See this article in the JRuby wiki.

Example: If my project directory is Hello, all my files are in src, I have a dist folder created for my jar file, my main file is called HelloWorldApp.rb, my app's name is "Hello World App", and I want the customization info, the command line would look like this:

jrubyfx-jarify src --main src/HelloWorldApp.rb dist/HelloWorldApp.jar --native --name "Hello World App" -v

Also note that you can do this in code, see samples/fxml/Demo.rb for the rake task usage.

Samples

To run sample:

jruby samples/fxml/Demo.rb

Or, if you have not installed the gem, or are testing edits to jrubyfx.rb:

rake run main_script=samples/fxml/Demo.rb

To run all samples (a nice quick way to make sure you didn't break anything), run:

jruby -I lib samples/test_all_the_samples.rb

Several other files that can be used as examples are in the tests/ folder

Creating Application and Controller

Require the 'jrubyfx' file/gem, and subclass JRubyFX::Application (and JRubyFX::Controller if you are using FXML). At the bottom of the file, call yourFXApplicationClass.launch(). Override start(stage) in the application. See samples/fxml/Demo.rb for commented FXML example, or the fils in samples/javafx for non-FXML (programatic JavaFX, but you should really look into FXML, its better) or see the Getting Started Guide and the Syntax Notes on the JRubyFX github wiki

If you want rdoc, run rake rdoc. Please note that there are lots of generated methods and conventions that are not in the RDoc. Please read the Getting Started Guide or the tutorials.

Issues

Errors loading JavaFX are bugs. Please report if you encounter this issue, tell us your platform, OS, and version of JRuby
Jarify command needs the jar executable in your path.
Any other difficulties are bugs. Please report them

jrubyfx's Issues

Windows: LoadError: no such file to load -- jfxrt

So after the earlier issue, wanting to test the packaging tools on Windows, and finally getting the jarify command working in spite of my Windows ignorance, I went to run the jar and it wouldn't run. So I tried just running the the source, the samples, they all kept getting the above error, which indicates-- for those who may find this when searching later-- that the jfxrt.jar isn't on the classpath.

I tried all manner of methods to get this working, uninstalling jdk8 and installing jdk7, changing java_home, setting classpath from the command line, trying the java installed in different places "ProgramFiles", "C:", "User/Me", I even used a Maven plugin which is supposed to fix issues with JavaFX, Windows and the classpath, that I'd read about a short while ago.

Still kept getting the below error:

LoadError: no such file to load -- jfxrt

Finally, found in jrubyfx / lib / jrubyfx / jfx_imports.rb where it would check for an environmental variable called "JFX_DIR", so once I set that everything began to work as expected so far.

I've VERY possibly missed something simple that would have solved this, but figured it was also likely either no one was using windows or they were using IDE's which were managing this. Sorry so long-winded, wanted to make sure to point out what did not work, though.

Got WebStart working

This may not be the right place for this, but yeah, figured out the webstart thing. There's not really a good way to automate it on our end, as far as I can tell, because it requires signing the jar, but anyways here's my blog post about it:

http://nodehed.com/?p=109

Unknown property type error after loading 1.0

Trying to get past my last bug reported. I loaded jrubyfx 1.0 and now I'm getting unknown property type errors where I wasn't getting them before. The class below TbEntity was successfully used as collection type for a list within a tableview.

Apparently , the error is in the method <fxml_accessor> here:

ptype.java_class.java_instance_methods.find_all{|x|x.name == "getValue"}

i.e. the above returns an empty array.

Again, I was successfully making those calls based on prior git repo source code.

The code says to manually supply a which I didn't have to before. By do we mean Ruby type i.e. in this case a String ?

Stack:

RuntimeError: Unknown property type. Please manually supply a type or report this as a bug

Jrubyfx apparently causing issues with ruby-debug-ide

This is all about supporting 2.0 lang level in 1.7.4 including debug support. JetBrains just released a patch i.e. ruby-debug-base 0.10.5.rc5 which allows debug in 2.0 mode, however the issue is with: ruby-debug-ide 0.4.18 which has been available in RubyMine for a bit.

If you don't require jrubyfx , this all works i.e. on top of the jruby 1.7.4 sdk

Please see gist: https://gist.github.com/amiracam/6126346

issues with jrubyfx-jarify command

jruby -v:

I am having issues with jrubyfx-jarify command.
I created "example" folder in "C:" and I made a subfolder in it called "app".
Inside of "app" I have my_script.rb and Ui.fxml.
Then I try running this from "C:\example"

jrubyfx-jarify app\ --main app\script.rb myapp.jar

which outputs:

which seems correct, but then when I run java -jar myapp.jar from "C:\example" I get this:

What's going wrong here?
Hope you can help, thanks.

I got to this after setting JFX_DIR env. variable to C:\Programmi\Java\jre7\lib because jrubyfx complained that I had an old version of Java or I had JFX_DIR var not set...

Is there anything wrong with my setup?

A "Getting Started" would be nice...

Dear folks,

This looks like it could be a useful project for folks trying to use JavaFX with JRuby for creating desktop GUI's. I'm guessing it's a little like MonkeyBars but for JavaFX rather than for straight Java Swing. However, as I am not a Java guru - and am only really just getting to grips with Ruby (let alone JRuby) it would be nice if the readme.md in this project had slightly more info/help than the Build section does right now.

Issue with FXCollections in FXML Files

Hi,

I am trying to use the Table View with JRubyFX. I am using the latest version (not the 0.9.2) series because I also want to help and report issues as I find them.

Below is the section of the FXML file that implements the table view (and my FXML file is based on the example for Table Views in the Oracle JavaFX documentation):

       <TableView fx:id="table_stock_data" prefHeight="260.0" prefWidth="390.0">
          <columns>
            <TableColumn maxWidth="5000.0" minWidth="10.0" prefWidth="315.0" text="Stock">

Removing the <FXCollections></FXCollections> section solves this problem, but of course I cannot then get data into the table.

I have actually forked this project and JRubyFX_FXMLLoader, but I don't know that my programming skills are strong enough to be able to help. I would like to help with documentation though. I am really excited about JRubyFX as I feel that it is the PERFECT solution for me, and I really want to see it succeed, which is why I would like to help in any way I can.

Lazily load javafx classes

the java_includes require lots of unnecessary startup time for most cases. Make it lazy

Allow registration of user-definable types and the ability to change defaults in dsl

When you construct your own classes you want to be able to make those classes fit into and feel like the main DSL. We already had an unused register_type method for this purpose but I am changing it a little bit:

register_type(type, name=nil)

So when with this in place I can:

class MultiTouchPane < Java::javafx::scene::layout::Region
  register_type self
end

and then use it in my dsl:

      layout_scene(400, 400, :black) do
        group do
          multi_touch_pane(image)
        end
      end

Drag & Drop treeview

Can someone help me to get this: http://stackoverflow.com/questions/11242847/is-drag-and-drop-supported-by-treeitem implemented using jrubyFX? I've got the tree working, which was simple, but the drag and drop bits use a callback mechanism which I'm not sure how to translate into jrubyfx.

jit fails on getters

jit leaves out getters, like styleclass.add(...) and nested properties:
CustomControl > ui > children

Set conflicts with java.util.Set in fxmllloaader

the Datamapper "finalize" instigated error in the gist below I encountered in the context of jrubufx i.e. upon launching a UI I try to setup a Datamapper db if not already present. I can certainly create Datamapper dbs otherwise in Jruby .This seems to be a low level issue but I have not experienced it in Jruby itself so I thought I ask before digging further. The stack can be found here:

https://gist.github.com/amiracam/6055902

Apparently, the issue is in the instantiation of the class Set

Create AOT/JIT cache

bug trying to implement an editable table field

following the oracle javafx tutorials , here:

http://docs.oracle.com/javafx/2/ui_controls/table-view.htm

I setup the following code in jruby:

@entity_type_col.setCellFactory(TextFieldTableCell.forTableColumn())

where @entity_type_col is the fxid for a column in a table control

and yes I have the appropriate import statements and I have confirmed via the debugger that I have the appropriate Java entity

I have confirmed that just doing the same in Java i.e. not specifying the setOnEditCommit handler will not cause a crash in Java

unfortunately it does in jrubyfx ie. just setting the the cell factory with the pre-existing Java construct will cause an error, I get the following:

SEVERE: javafx.scene.control.Control loadSkinClass Failed to load skin 'StringProperty [bean: TableRow[id=null, styleClass=cell indexed-cell table-row-cell], name: skinClassName, value: com.sun.javafx.scene.control.skin.TableRowSkin]' for control TableRow[id=null, styleClass=cell indexed-cell table-row-cell]

DSL via method missing will sometimes add something it should not

Let's say I have a code snippet like:

set_clip rectangle(smooth: true)

If this is executed in a class which can contain children it will add the rectangle as a child and then blow up when trying to set that same rectangle as the clip region. I propose we extend our DSL api so that:

set_clip rectangle!(smooth: true)

By specifying the '!' we are saying we acknowledge it is our responsibliity to deal with the rectangle and that the DSL should not bother to add it for us. Any comments on this? I feel like this is part of the devils bargain for having a nice DSL syntax. I definitely do not want to make adds explicit again.

Release a gem?

We easily have enough content in this library to do a gem release. Is there anything sketchy we should fix before putting out a release? Getting a release out would be good to get more people playing with this.

FXML Issue with the alignment attribute

Hi,

Let me start by saying that I am really excited about JRubyFX. I have started working with it and one of the first things I tried (after the Getting Started Guide), was to recreate the FXML example from www.oracle.com. This example uses a <GridPane> element and I was unable to get it to work. I was getting the following error:

Fragment of fxml file:

  <GridPane fx:id="rootGridPane" xmlns:fx="http://javafx.com/fxml" alignment="center" hgap="10" vgap="10">

If I remove the alignment attribute, the code works fine.

I noticed that this also occurs for <HBox> as well. I haven't tried other elements yet.

Thanks,
Sean

Allow jrubyfx-jarify to AOT compile Ruby source as an option (or maybe as default)

This is opened as a feature request in reponse to #26. I wrote it up as a feature request. When we run jrubyfx-jarify we should allow AOT compilation for partial obfuscation. It is not a ton of obfuscation but it is enough to discourage casual cheating. People will keep asking for this as well, so we might as well do it.

Override enum & enum-like value comparison

> jfxObject.enum_prop = :enum_value
> jfxObject.enum_prop == :enum_value
false
> jfxObject.enum_prop == EnumType::EnumValue
true

This is the current behavior pattern of enums. We need to override comparisons so that it meets expectations. This can probbably go with the enum injection code in dsl.rb. Annoys me the most often with KeyCodes

Building a jar doesn't include .fxml files

I got the "rake jar" task to run by cd'ing into my clone of the jrubyfx repo, and running it like:

jruby -S rake jar main_script=~/projects/jrubyfx_projects/Hello/src/hello2.rb

This properly built the jar for me, except it doesn't seem to include my fxml file. My hello2.rb file looks like:

require "jrubyfx"

class HelloWorldApp < JRubyFX::Application
  def start(stage)
    with(stage, title: "Hello World!", width: 800, height: 600)
    HelloWorldController.load_fxml("Hello.fxml", stage)
    stage.show()
  end
end

class HelloWorldController < JRubyFX::Controller
  fx_id :helloLabel

  fx_handler :sayClicked do
    @helloLabel.text = "You clicked me!"
  end
end

HelloWorldApp.launch

And trying to run the jar gives this error:

jar archive created with "jrubyfx-jarify" command contains ruby script sources

Forgive me if this is not the section for something more like a feature request than a bug, but I was assuming that .rb files inside jar would have been AOT compiled to java bytecode, instead of being stored as plain ruby scripts.
Or is there something I can do to obtain this before running "jrubyfx-jarify" ?
Thanks

Make it faster by pre-compiling class injections

reflection is slow, so if we pre-compile all of it, startup time will be faster (tested with old version reveal startup times goes from 15 seconds to 6 second)

It generates the code fine, and the resulting ruby script can be run directly with jruby without error! I've tried using both jrubyfx-generator directly, as in the above error, and using the .bat file. Was fixing a problem with my plugin and then discovered this underneath. Pushing PR that checks for Windows and just doesn't launch the generated app if it is.

License missing from gemspec

RubyGems.org doesn't report a license for your gem. This is because it is not specified in the gemspec of your last release.

via e.g.

spec.license = 'MIT'
# or
spec.licenses = ['MIT', 'GPL-2']

Including a license in your gemspec is an easy way for rubygems.org and other tools to check how your gem is licensed. As you can imagine, scanning your repository for a LICENSE file or parsing the README, and then attempting to identify the license or licenses is much more difficult and more error prone. So, even for projects that already specify a license, including a license in your gemspec is a good practice. See, for example, how rubygems.org uses the gemspec to display the rails gem license.

There is even a License Finder gem to help companies/individuals ensure all gems they use meet their licensing needs. This tool depends on license information being available in the gemspec. This is an important enough issue that even Bundler now generates gems with a default 'MIT' license.

I hope you'll consider specifying a license in your gemspec. If not, please just close the issue with a nice message. In either case, I'll follow up. Thanks for your time!

Appendix:

If you need help choosing a license (sorry, I haven't checked your readme or looked for a license file), GitHub has created a license picker tool. Code without a license specified defaults to 'All rights reserved'-- denying others all rights to use of the code.
Here's a list of the license names I've found and their frequencies

p.s. In case you're wondering how I found you and why I made this issue, it's because I'm collecting stats on gems (I was originally looking for download data) and decided to collect license metadata,too, and make issues for gemspecs not specifying a license as a public service :). See the previous link or my blog post about this project for more information.

Using Low Level Binding API in jrubyfx

    db = MyDoubleBinding.new(a, b, c, d)
    puts db.get

    puts db.get
  end
end

Calling JRubyApplication.set_on_action yields an Exception

https://gist.github.com/komax/5933828
Everything works, except the set_on_action call back (with just puts, it works). On my linux mint 14 with oracle jdk7 and jruby master, I get this error:

jrubyfx native packaging not up to date ?

apparently jrubyfx jdk 8 is still required or checked for although Oracle's JDK and packaging tools already support native packaging i.e. jdk 1.7x certainly 0_25, 0_45

is this a matter of an out of date check still being in place ?

thanks

fx:id="location" is overridden by hidden URL @location field in controllers

it should be the other way around

@location.text = "blah"

complains that @location does nt have text= method because its a URL when in a controller class

fx:id sometimes is not set as the id

fix dsl precompiled nested classes

class Java::JavafxSceneControl::ScrollPane
  include JRubyFX::DSL
  def hbar_policy=(rbenum)
    java_send "setHbarPolicy", [Java::JavafxSceneControl::ScrollBarPolicy],  JRubyFX::Utils::CommonConverters.parse_ruby_symbols(rbenum, Java::JavafxSceneControl::ScrollBarPolicy)
  end

is wrong, Java::JavafxSceneControl::ScrollBarPolicy => Java::JavafxSceneControl::ScrollPane::ScrollBarPolicy

Symbol conversion procs should report better message

When you call a color converter (just an example) which takes a symbol we get a rather weird error message to anyone who is not a JRubyFX hacker:

Exception running Application:
#<TypeError: cannot convert instance of class org.jruby.RubySymbol to class javafx.scene.paint.Paint>
/Users/enebo/work/jrubyfx/lib/jrubyfx/core_ext/precompiled.rb:908:in `fill='

Now we know something went wrong with fill= but this is pretty confusing to new users and we can give better feed back. Here is what I have a patch for (I will commit it as a discussion provoker):

Exception running Application:
#<ArgumentError: No such color: redbull>
/Users/enebo/work/jrubyfx/lib/jrubyfx/utils/common_converters.rb:144:in `CommonConverters'
org/jruby/RubyProc.java:264:in `call'
/Users/enebo/work/jrubyfx/lib/jrubyfx/core_ext/precompiled.rb:908:in `fill='

So the backtrace now shows common converters and the proc call for the converter but the message is likely to be really obvious. It would be possible to make a much more sophisticated coercion mechanism but I feel this is a big improvement for a tiny amount of work.

It looks like the fxmlloader has problems with these namespaces

With

it works correctly.

slightly more complex fxml doesn't load

I created an fxml file that used split panes , basically a left nav pane holding a liar and on the right a top and bottom panes both holding tables. A header section containing labels and a basic user login pane.

I would attach the fxml in question but I don't see how to do that here, other than to copy it to the bottom of this issue.

here's the fxml in question:

Better mechanism for non-DSL calls using converters (or make converter_for do more)

I just hacked this for drag_event.rb:

  tmc = enum_converter(Java::javafx::scene::input::TransferMode)
  converter_for :accept_transfer_modes, &tmc

  # FIXME: For non-dsl calls like this we want converter logic
  alias :accept_transfer_modes_orig :accept_transfer_modes
  def accept_transfer_modes(*values)
    accept_transfer_modes_orig *attempt_conversion(self, "accept_transfer_modes", *values)
  end

This snippet shows how I worked around being able to:

        event.accept_transfer_modes :move

Notice since we are just calling a method on an object our DSL is not firing the converters on the arguments. I was going to just make another method for this but I am wondering whether converter_for should do this logic by default. What do we think?

Create CSS compiler

Apparently it happens in Java.

Add inspect overrides for better debugging

Lots of classes are opaque except for oracle documentation. override .inspect to make it easier to see what is available

#<NoMethodError: undefined method `layout_scene' for #<Java::JavafxStage::Stage:0x5eea82fc>>

So, I've been doing some experiments the past few days trying to figure out the webstart stuff, and in doing so hit upon a weird bug. If I have a jruby-complete.jar with jrubyfx copied in, I can certainly run jrubyfx apps with it like:
java -jar jruby-complete.jar hello.rb and it works like a charm. But given the same jar, let's say I have this ruby class:

require "jrubyfx"

class Hello < JRubyFX::Application

  def start(stage)
    with(stage, title: "Hello JRuby", x: 105, y: 140) do
      stage.layout_scene(500, 250, :black)  do
        hbox(padding: insets(60)) do
          text('JRuby', font: font('sanserif', 80)) do
            fill linear_gradient(0,0,0,1, true, :no_cycle, [stop(0, :pale_green), stop(1, :sea_green)])
          end
          text('FX', font: font('sanserif', 80)) do
            fill linear_gradient(0,0,0,1, true, :no_cycle, [stop(0, :cyan), stop(1, :dodger_blue)])
            set_effect(drop_shadow(color: :dodger_blue, radius: 25,spread: 0.25))
          end
        end
      end
      show
    end
  end
end
Hello.launch

And try to call it from a launcher like this:

import javafx.application.Application;
import javafx.stage.Stage;
import javafx.concurrent.Task;
import org.jruby.embed.ScriptingContainer;

public class Launcher extends Application {
  public static void main(final String[] args) {
    Application.launch(args);
  }

    public void start(final Stage stage) throws Exception
    {

       Task task = new Task<Void>()
       {
           @Override
           protected Void call() throws Exception
           {
               ScriptingContainer container = new ScriptingContainer();
               container.runScriptlet("require 'hello.rb'");
               return null;
           }
       };

       new Thread(task).start();
    }
}

Then I get the following error:

Exception running Application:
#<NoMethodError: undefined method `layout_scene' for #<Java::JavafxStage::Stage:0x7f243900>>

Ignore that I'm probably doing all sorts of horrible things with this code, since it's just experimental, but for whatever reason, in this situation, layout_scene (and perhaps other parts of the DSL, I don't know yet) vanish. The very same java launcher is perfectly capable of launching other far more complex JRubyFX apps, that use FXML and CSS, but toss in layout_scene and it breaks down. Just thought I'd get this in while it was fresh in mind. Thanks. Seems like at some point, scripting existing javafx apps with jrubyfx might be an interesting use case, so thought it would be worth mentioning that this happens.

(Still haven't gotten webstart/jnlp working, but I think I'm starting to get useful errors finally so that's always a good sign).
