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?

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

it should be the other way around

Apparently it happens in Java.

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:

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is this a matter of an out of date check still being in place ?

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.

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.

I've installed the gem form today's master from github. Errorlog: https://gist.github.com/friflaj/4960358

I took the demo sample files from the samples/fxml directory and tried running from the command line as per instructions which failed but then set it up an IDEA project with the respective source files. I'm Mac OS X 10.8.3 , Jruby 1.7.3, on Java 1.7, jruby 0.9.2

it fails here:

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

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

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.

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.

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]

etc ....

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

During development the usage of the .add_change_listener method works correctly, however once you try running the jarified version of the program java throws the following error

Exception running Application:
#<TypeError: illegal access on 'addListener': Class org.jruby.javasupport.JavaMethod can not access a member of class javafx.scene.control.TextInputControl$TextProperty with modifiers "public">

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)

I tried several version, but I cannot remove this error. The call to super has now parameters like the JavaFX suggests. Any suggestions what is wrong with the above code?

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.

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

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:

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.

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.

I program a bit on JavaFX for my GSoC project in jrubyfx. The form view example
http://docs.oracle.com/javafx/2/get_started/form.htm#BABHABBF
looks like this in jrubyfx

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:

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

It looks like the fxmlloader has problems with these namespaces

xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2"

With

xmlns:fx="http://javafx.com/fxml"

it works correctly.

Compare
jruby/jruby-visualizer@bf959d3#lib/ui/jruby-visualizer.fxml

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

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.

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

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">
                <cellValueFactory>
                    <PropertyValueFactory property="symbol" />
                </cellValueFactory>
            </TableColumn>
            <TableColumn prefWidth="75.0" text="Shares">
                <cellValueFactory>
                    <PropertyValueFactory property="shares" />
                </cellValueFactory>
             </TableColumn>                   
          </columns>
          <items>
            <FXCollections fx:factory="observableArrayList">
            </FXCollections>
          </items>
        </TableView>

I get the following error:

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.

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

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>>
/home/eric/projects/jrubyfx_projects/jrubyfx_web/hello.rb:7:in `start'

org/jruby/gen/InterfaceImpl1339899994.gen:13:in `run'

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).

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:

on latest jruby, jrubyfx and fxmlloader creates these warnings:

jruby property_demo.rb

Or may I use another way for High Level Binding in jrubyfx?

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 error stack:

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?

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

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.

So running the jrubyfx-generator gives this very weird error on Windows when it tries to launch the app after generating the ruby code:

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.

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.
