JavaFx 8 FXML CellFactory own

Hello

I wrote my own Cell Factory:

public class ServerCommitTextFieldTableCell<Role, String> extends TextFieldTableCell<Role, String> {
   
     @Override
     public void commitEdit(String val)
     {
        super.commitEdit(val);
        System.out.println("update!");
     }
}

and I'm trying to use it in a dialogue of fxml definition:

<TableColumn id="col1" fx:id="col1" prefWidth="150.0" text="Name">
     <cellFactory>
          <ServerCommitTextFieldTableCell fx:factory="forTableColumn" />
     </cellFactory>
     <cellValueFactory>
          <PropertyValueFactory property="name"/>
     </cellValueFactory>
</TableColumn>

I expect to get the "update!" in the console, whenever I have change the cell and press enter in the textfield in the TableView, but this does not happen.

I use 8 build JavaFx 1.8.0_05 - b13

Could someone help me with the problem?

OK, I found the answer

FXML:

and I had to define my new cell and it's factory:

public class ServerCommitTextFieldTableCell extends TextFieldTableCell {

    static Logger LOGGER = Logger.getLogger(ServerCommitTextFieldTableCell.class);

    public ServerCommitTextFieldTableCell(){
        super((StringConverter)new DefaultStringConverter());
    }

    @Override
    public void commitEdit(String val)
    {
        super.commitEdit(val);
        LOGGER.info("updated:"+ val);
    }
}

public class ServerCommitTextFieldTableCellFactory  implements Callback, TableCell> {

    @Override
    public TableCell call(TableColumn param) {
        return new ServerCommitTextFieldTableCell();
    }
}

My old code will not work: the fx:factory can be used to provide a factory No.-arg method.

The only way I can see to make it work is to do something like
```
package view.components;

import javafx.scene.control.TableCell;
import javafx.scene.control.TableColumn;
import javafx.scene.control.cell.CheckBoxTableCell;
import javafx.util.Callback;

public class CheckBoxCellFactory
implements Callback, Callback, TableCell>> {

  public Callback, TableCell> call(TableColumn paramAnonymousTableColumn) {
    return CheckBoxTableCell.forTableColumn(paramAnonymousTableColumn).call(paramAnonymousTableColumn);
  }
}
```
It called CheckBoxTableCell.forTableColumn (...) whenever he needs a new table cell. If you did this in Java, rather than FXML, you'd
```
col1.setCellFactory(CheckBoxTableCell.forTableColumn(col1));
```
who creates the cell factory only once. I don't think it's a problem, but in this case, you could do something more sophisticated in your CheckBoxCellFactory. (Perhaps to set a property of 'column', that you can set from the FXML and then set a private reminder that is bound to the column property, assigning the result of CheckBoxTableCell.forTableColumn (...) when the column property.)

JavaFX, I18N, FXML and me
Hello all!

I'm looking for ideas on how to to internationalize/locate my FXML JavaFX application file. I am familiar with the method of bundle traditional resources and use that in my controller for everything I do in the user interface during execution, but, obviously, I need to extend that to my FXML file as well. Here are a few thoughts on how I could address the issue:

* A FMXL file that is dynamically loaded for each locale I support? (I don't like this approach that minor changes to my XML must be propagated to all of the locale specific versions).
* Or... Somehow through the scene graph once the FXML is responsible, looking for text I can load from a resource group.

I hope you JavaFX veterans may know a better way to handle this.

Thank you very much!

-Zep
You can use the resources resolution operator to locate a FXML file when it is loaded:

http://docs.Oracle.com/JavaFX/2/API/JavaFX/fxml/doc-files/introduction_to_fxml.html#resource_resolution

You just pass FXMLLoader an appropriate resource bundle at load time.

JavaFx and fxml in an OSGI runtime
Hello

I work to run javafx in the Apache felix osgi runtime,
using Bundle-NativeCode and many import/export-package, I do a javafx bundle, that works perfectly to run javaFx interfaces written in plain java...
but, when I try to load a fxml file I get this question:
```
javafx.fxml.LoadException: BorderPane is not a valid type.
     at javafx.fxml.FXMLLoader.createElement(Unknown Source)
     at javafx.fxml.FXMLLoader.processStartElement(Unknown Source)
     at javafx.fxml.FXMLLoader.load(Unknown Source)
```
the exception I don't give no information more... someone knows more about this exception to help understand this error?

PS. : the same file fxml will work fine outside the osgi runtime.

Best regards.

Sounds like a problem of ClassLoader. Make sure that the FXMLLoader using the same classloader as the OSGi runtime. Unfortunately, JavaFX 2.0 does not allow you to specify a custom class loader, so you'll need to use JavaFX 2.1 for this. See FXMLLoader #setClassLoader ().

Option buttons: ToggleGroup in JavaFX 8 (FXML)

Hello!

Since JDK8 b115 or b116, toggle groups of option buttons seems to not want to work more in the FXML files.

Before, it worked:

<fx:define>
    <ToggleGroup fx:id="RB_Group" />
</fx:define>
<RadioButton fx:id="rb1"  mnemonicParsing="false" toggleGroup="$RB_Group" />
<RadioButton fx:id="rb2"  mnemonicParsing="false" toggleGroup="$RB_Group" />
<RadioButton fx:id="rb3"  mnemonicParsing="false" toggleGroup="$RB_Group" />

Then I tried the following...

    <ToggleGroup fx:id="RB_Group">
        <toggles>
            <RadioButton fx:id="rb1"  mnemonicParsing="false" />
            <RadioButton fx:id="rb2"  mnemonicParsing="false" />
            <RadioButton fx:id="rb3"  mnemonicParsing="false" />
        </toggles>
    </ToggleGroup>

who does not work either.

Then, I tried 2 scene generator, but I could not find any possibility to define groups of on/off radio buttons.

No idea how to get it working again? Separated radio buttons are pretty useless...

Thank you and best regards,

JavaFX 2.0. Samples FXML - TabPane explicit
Hello community,

First of all I must say that I am very impressed by the powerful new features of JavaFX 2.0.

Currently I use a FXML file to create my Userinterface. It works like a charm.
But unfortunately I have problems with the "TabPane.
I don't seem to be able to create child controls in the TabPane/tabs tab /...

My Code example:
```
<BorderPane fx:controller="fxmlexample2.Fxmlexample2Controller"
    xmlns:fx="http://javafx.com/fxml">
    <center>
        <TabPane >
            <tabs>
                <Tab fx:id="tab1" text="%tab1" closable="false">
                //?????? How to add some content?    
                </Tab>
            </tabs>
        </TabPane>
    </center>
</BorderPane>
```
Y at - it interesting a tutorial?

Thanks for any help.

Try replacing ' / /? How to add content? "with:
```
    
```
I don't think that there is a specific tutorial TabPane, but this more general introduction to FXML be useful:

FXML: < fx: include / > with the attribute of resources. How does it work?

Hello
I am trying to understand FXML and I struggle with the help of ResourceBundles / internationalization.
I did a common component, which relies on its own resources file, let's say the package 'fxml', I have:
Control.fxml
Control.Properties
Control_de. Properties
Another FXML includes this one:
<? import javafx.scene. *? >
<? import javafx.scene.control. *? >
<? import javafx.scene.layout. *? >
< fx:root type = "javafx.scene.layout.VBox" xmlns:fx =" " http://JavaFX.com/fxml ">
< fx:id TextField = "textField" / >
"< fx: include source="/fxml/Control.fxml ' resources = "fxml. Control"/ >
< / fx:root >
If I load only through:
LoginView parent = FXMLLoader.load(getClass().getResource("/fxml/Login.fxml"), ResourceBundle.getBundle ("fxml. User name'));
I get the following exception:
Caused by: java.lang.NullPointerException
at java.util.ResourceBundle.getBundle(ResourceBundle.java:1026)
to javafx.fxml.FXMLLoader$ IncludeElement.processAttribute (FXMLLoader.java:897)

to fxml. JavaFXApp.start (JavaFXApp.java:19)
What's not here? fxml. Control.Properties there permanently.
If I remove the < fx: include / > element, everything works fine.
Is it possible to include resources directly in a FXML, so that I don't have to specify them again in each include?

I'm guessing that this is the problem that you run in:

How is used with fx i18n resources: include?

FXML showing does not setText()

Hello world

I started playing a few days with JavaFX looks excellent! I am a beginner and got stuck on a trivial problem.
I played with two classes which extend 'Step' MainStage.java other MessageBox.java and MessageBoxOk.fxml
I'm trying to take another step the error message and display it in my MessageBox class.

PROBLEM:
-When I try to move the empty constructor error I get javafx.fxml.LoadException: java.lang.InstantiationException: org.testfx.admin.misc.MessageBox
-When I put it trough a public method in the MessageBox (as in the code below), I get no error but FXML displays earlier then the method is executed

How would pass all the data from one step to another step that it displays in FXML during initialization of the class. It seems that what I put the public method hollow is 'too late' and constructor to throw an error?

Thank you!

Method on the mainstage:

public void isDataOk() {
          if (checkFields(false)) {
               try {
                    AppDBAccess dbAccess = new AppDBAccess(tfHost.getText(), tfDbName.getText(), tfUsername.getText(), tfPassword.getText(),
                              Integer.valueOf(tfPort.getText()));
                    dbAccess.closeConnection();
                    lblStatus.setText(MyConstants.STRING_FIELD_CONNECTED);
               } catch (NumberFormatException e) {
                    e.printStackTrace();
                    MessageBox msgBox = new MessageBox(e.getMessage());
               }

MessageBox msgBox = new MessageBox();
msgBox.initMessageBox(e.getMessage(), MessageBox.MESSAGE_OK, "Connection Error");

My MessageBox.java:

public class MessageBox extends Stage {
     public static final int MESSAGE_OK = 1;

     @FXML
     private Label lblMessage = new Label();

     public void initMessageBox(String message, int messageType, String messageBoxTitle) {
          Parent fxmlFile = null;
          try {
               if (messageType == MESSAGE_OK) {
                    fxmlFile = FXMLLoader.load(getClass().getResource("MessageBoxOk.fxml"));
               }
               Scene scene = new Scene(fxmlFile);
               scene.getStylesheets().add("style.css");
               this.initModality(Modality.APPLICATION_MODAL);
               this.setResizable(false);
               this.setTitle(messageBoxTitle);
               this.setScene(scene);
               lblMessage.setText(message);
               show();
          } catch (IOException e) {
               e.printStackTrace();
          }
     }

My FXML:

<?import javafx.scene.layout.VBox?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.control.Button?>

<VBox 
     id="someBox"
     prefHeight="100" 
     prefWidth="300"
     fx:controller="org.testfx.admin.misc.MessageBox"
     xmlns:fx="http://javafx.com/fxml">
     <children>
          <Label fx:id="lblMessage"></Label>
     </children>
</VBox>

How you use FXML is not quite the way it is expected (though I would have preferred that it is how you try to use it because it would be much more intuitive and more versatile).

When you call FXMLLoader.load (getClass () .getResource ("MessageBoxOk.fxml")) the FXML charger has actually instantiates a new instance of the "controller", which in your case is MessageBox.java. In your code you manually instantiate a plus, so you end up with 2 instances of MessageBox.java, only one is actually connected to the view and the other is referenced by your code.

To do what you're trying to do, you will have to get my hands on the controller that was instantiated by the FXML charger and not 'new' your own copy. FXMLLoader allows to do this but only if you a few stop and use the non-static version of the load method.

There are a bunch of different ways to do it, but keeping relatively faithful to your current setup, I recommend you do something as follows:

public class MessageBox
{
    public static final enum Type { ok }

    public static void showMessageBox(String message, Type type, String title)
    {
        MessageBox messageBox;
        Parent messageBoxRootNode;
        switch (type)
        {
            case ok:
                String fxmlFile = "MessageBoxOk.fxml";
                try
                {
                    InputStream fxmlStream = MessageBox.class.getResourceAsStream(fxmlFile);
                    FXMLLoader loader = new FXMLLoader();
                    loader.setBuilderFactory(new JavaFXBuilderFactory());
                    loader.setLocation(MessageBox.class.getResource(fxmlFile));
                    messageBoxRootNode = (Parent) loader.load(fxmlStream);
                    messageBox = (MessageBox) loader.getController();
                }
                catch (IOException e)
                {
                    throw new RuntimeException("Failed to load FXML file: " + fxmlFile, e);
                }
                break;
            default:
                throw new IllegalArgumentException("Unsupported message type: " + type)
        }

        messageBox.setMessage(message);

        Scene scene = new Scene(messageBoxRootNode);
        scene.getStylesheets().add("style.css");
        Stage stage = new Stage();
        stage.initModality(Modality.APPLICATION_MODAL);
        stage.setResizable(false);
        stage.setTitle(title);
        stage.setScene(scene);
        stage.show();
    }

    @FXML private Label lblMessage = new Label();

    public void setMessage(String message)
    {
        lblMessage.setText(message);
    }
}

And from your code calling (i.e. your catch clause) do like this:

MessageBox.showMessageBox(e.getMessage(), MessageBox.MESSAGE_OK, "Connection Error");

Differences between JavaFX CSS and css w3c standard
This is a discussion topic that comes to mind after reading the comments in this thread Re: FXML, css and - fx-are-family

Feel free to comment or share your ideas on the subject.

Note that these comments relate to the meaning of assignment of names and semantics of the css tags and not the syntax and parsing of css (such as the w3c css and css javaFX seem to be equivalent with respect to later).

You know, sometimes I find refreshing absence of JavaFX features in css. It is nice to have, well, almost everything, the JavaFX CSS documented on one page. I think that if you were to do the same for the w3c css then it would end up with a much bigger, more difficult to understand the document and even what should be the content of this document would probably quite controversial, in the same kind of way that ends up being the HTML5 specification. Microsoft has helped more than 7,000 w3c tests just to cover only a subset of css rules that are available in browsers today. The webkit project lists open CSS nearly a thousand bugs: https://bugs.webkit.org/buglist.cgi?product=WebKit & component = CSS & resolution =-. If the implementation even partial w3c CSS support is a complex project.

When I started using JavaFX CSS I found differences in w3c CSS quite shocking, and it was difficult to account for their. Now that I'm used to JavaFX CSS, I don't have as much of a problem. The difference in names and semantics will be an obstacle to working on JavaFX developers who are familiar with w3c CSS - but the designers quickly will also discover that FXML is not HTML and Java isn't JavaScript and JavaFX deployment is not HTML deployment. Then, perhaps, in the bigger picture, it is not as big a deal that he would appear. Yet, one cannot think that any obstacle to the people easily pick up and adopting JavaFX makes the technology a disservice.

There are other benefits that the JavaFX CSS in its own space of names to w3c css, in what she can evolve separately, it shouldn't be exactly the same because it has a different name, it should not implement fully w3c css as browsers do so because it is clearly something different by name etc. There is even precedent for it in the use of mozilla to moz - CSS and css properties http://css-infos.net/properties/webkit - web webkit prefixes as not in standard as many people have suggested. JavaFX CSS supports a JavaFX rendering engine and not an HTML rendering engine. It is quite remarkable that Oracle has been able to build and make available a model CSS for JavaFX which feels as familiar as to the w3c css, w3c css is very strongly targeted towards style a game completely different technology (HTML markup document object model and).

It would be useful to have a tool which translates as w3c css to the approximations of JavaFX css and vice versa, or the ability for JavaFX to have a mode (perhaps a Boolean value when a style sheet is loaded) to perform an automatic alias or the mapping of the w3c css for javafx (at least for the subset of w3c css that would make sense to automatically translate for JavaFX css). I haven't checked the jira JavaFX in detail, then maybe a request for support already exists - it's perhaps in the private http://javafx-jira.kenai.com/browse/RT-9272 jira.

The JavaFX css model is really powerful and I found really useful some of the additions that it adds above the css 2.1 Basic found regularly in browsers. With the next CSS Java model object http://javafx-jira.kenai.com/browse/RT-17293, you will also better get access by Java programming.

Then, good work on the construction and implementation of this complex device...
Thanks for the comments. The gap between JavaFX CSS and CSS from W3C will be an evolutionary process. It would be nice to use the stylesheet of a standard basis, but there is not always a mapping from 1-1 to JavaFX. But for properties that can be mapped, it is something that should be supported. For example, we should be able to deal with 'police' or '- fx - police '.

FXML - Acess Enums or constants

Hello

FXML, is it possible to put a property with the value of an Enum or constant?

Example:

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.layout.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.*?>
<?import javafx.geometry.Side?>
<?import default.EnumExample?>


<VBox xmlns:fx="http://javafx.com/fxml">
     <children>
          <TreeView showRoot="false" fx:id="treeView">
               <root>
                    <TreeItem value="DbObjects">
                         <children>
                              <TreeItem value="EnumExample.A">                                
                              </TreeItem>
                              <TreeItem value="EnumExample.B">                                
                              </TreeItem>
                         </children>
                    </TreeItem>
               </root>
          </TreeView>
     </children>
</VBox>

Best regards.

Hello

Usually, you can use the name of the enum string and FXML it will force in what you need. In the case of the TreeItem element however, the 'value' is of type Object to FXML is unclear to you want to be forced to an enum. There are two ways you can work around this:

1. strongly type your TreeItem: create your own custom class that extends TreeItem and it take an enum value explicitly and then sets the value for you this Enum. Then fortunately FXML converts the string ('A', 'B', etc. in the Enum).

2 use some FXML slightly more verbose to inform the FXMLLoader what type you want to use for the enum. Something like the following

Hope this helps,

Custom components in FXML
Hello

I want to set in the FXML a custom component, something like MyTreeItem, which extends from TreeItem. To do this, I created a MyJavaFXBuilderFactory to return the correct constructor (MyTreeItemBuilder). MyTreeItemBuilder returns instances of MyTreeItem.

Note: Below, I send my courses and my tree.fxml.

Is it possible to include in the custom components of fxml?

When I run my application, I got this error:

com.sun.javafx.fxml.PropertyNotFoundException: "myvalue" property does not exist or is read-only.

Hello

When you include the code (and the stack traces) in your forum messages, please include in a tag {code} as shown: https://forums.oracle.com/forums/ann.jspa?annID=1622 this makes it more easy for us all to read.

Your code is sort of ok, but you have a lot of typos in your FXML and your Java code. Try searching for the code below instead. You don't actually have a constructor or by the way, it will work only without it.

Try this FXML:
```
    
        
            
                
                    
                        
                            
                                
                            
                        
                    
                
            
        
    
```
With that for your item custom:
```
package dummy.tree;

import javafx.scene.control.TreeItem;

public class MyTreeItem extends TreeItem
{
    public Object getMyvalue()
    {
        return super.getValue();
    }

    public void setMyvalue(Object value)
    {
        super.setValue(value);
    }
}
```
And for launch:
```
package dummy.tree;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class TestApp extends Application
{
    public static void main(String[] args) throws Exception
    {
        launch(args);
    }

    public void start(Stage stage) throws Exception
    {
        Parent rootNode = FXMLLoader.load(getClass().getResource("/tree.fxml"));
        Scene scene = new Scene(rootNode, 800, 600);
        stage.setScene(scene);
        stage.show();
    }
}
```
Also, I guess it is just a test case, but you don't need to provide your own "myvalue" getters/setters when this is delegated to super. Just use the 'value' property directly in your FXML.

A view Naming Convention, it should be myValue with getMyValue and setMyValue (e.g. capital 'V'). FXML is case-sensitive too, so if you change, you need to change your FXML for use myValue instead.

Hope that helps,

JavaFX scale canvas

I would have use a fixed pixel size canvas, which can be resized to fill a window and will increase when the window is resized.

I understand why the existing code is not suitable the canvas when the window is cultivated, but what I need to add to get there?

Also I need the canvas on the scale to maintain its underlying proportions (as specified by its width in pixels and height) and also to stay centered in the lowest node including the enclosing the proportions of the node is not the same as that of the canvas.

Any help appreciated gratefully.

Based on the code I found here I finally found a solution AutoScalingStackPane.

The AutoScalingStackPane applies a scaling to scale its content to fill or proportions (preserved) to the size of StackPane. I added an AutoScale property that allows you to choose the option scale (NONE, ADAPT, scale).

If you compile in a jar it can be used (and tested) with SceneBuilder.

Given that it required only so little of code, I wonder if StackPane this could include scaling functionality directly. It seems that it could be useful and there is no API changes (only the inclusion of the additional AutoScale property)

FXML 8 Binding Expression does not

While I do the Java for 15 years and more, I am new to JavaFX and FXML, so please don't mind if I ask something obviously stupid...
I put in place a liaison between my opinion FXML and the Java controller in the controller's initialize() method.
It works really well: this.countButton.disableProperty () .bind (this.model.countingProperty);
Now, I have discovered the FXML 8 documentation on the Expression bind (http://docs.oracle.com/javase/8/javafx/api/javafx/fxml/doc-files/introduction_to_fxml.html#expression_binding) and tried to do the same here: < button text = "Count" fx:id = "countButton" disable="${controller.model.counting}"/ > but that simply does Nothing. It throws an exception, or there is no link!
What is my fault?

If you want to make available to FXML this 'model', you need to set in FXML (AFAIK).

I don't have the time to test it now, but I think you can do
```
Model model = new Model(...);
FXMLLoader loader = new FXMLLoader(someURL);
loader.getNamespace().put("model", model);
Parent root = loader.load();
```
and then the FXML will 'see' the model. But it feels like a bit of a hack.

Please help me solve this problem

This is not a problem with FXML but with the axis lack of categories.

Article of Oracle bar graph, you need to do:

((CategoryAxis)stackChart.getXAxis()).setCategories(FXCollections.observableArrayList(Arrays.asList(austria, brazil, france, italy, usa)));

Or more simply:

((CategoryAxis)stackChart.getXAxis()).getCategories().setAll(austria, brazil, france, italy, usa);

For me, it solves the problem.

Can I put a controller in FXML when using fx:root for SceneBuilder 2 works better?

This sounds like an easy question, but I can't seem to find a way to make it work properly. I'm doing it with 2 SceneBuilder b14. The only way I am able to do SceneBuilder using custom components, I created using FXML is with a configuration as follows:

                BorderPane.alignment="CENTER"/>
    </center>
</fx:root>

two. TwoPane.java

package two;


import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.control.Button;
import javafx.scene.layout.BorderPane;


public final class TwoPane extends BorderPane {
    @FXML
    private Button button;
    @FXML
    public void initialize() {
        assert (button != null) : "The variable button must not be null.";
        button.setText("Updated Text");
    }
    public TwoPane() throws Exception {
        FXMLLoader loader = new FXMLLoader();
        loader.setLocation(getClass().getResource("TwoPane.fxml"));
        loader.setRoot(this);       // leaking 'this'?
        loader.setController(this); // leaking 'this'?
        loader.load();
    }
}

It's the kind of example, I see most often online, however, it is not possible to define TwoPane as a controller in the FXML file because it will cause an error. the control is already set via code. Because the control is not set through FXML, SceneBuilder will not pick up the @FXML components, so things like fx:id and onAction lists don't get filled.

I tried a few variations, but can't find anything that plays well with SceneBuilder. Any suggestions?

Hi there, don't you try to take a glance to the stage Builder reference samples? You will find the link on this page: JavaFX Developer Preview
