Combination of JavaFX FXML layout

Hi everyone)) recently I started using javafx and I wonder if there a way to combine the FXML provisions without Java code, like insert smaller layout in larger? (Thanks in advance))

logException GRAVE javafx.fxml.FXMLLoader: the specified language Page
Hi all
I do for example on http://docs.oracle.com/javafx/2/get_started/fxml_tutorial.htm#CHDDBEGD site Web Oracle and used the generator of scene for the fxml.

When I run the class I get this error
logException GRAVE javafx.fxml.FXMLLoader: the specified language Page

Then I copied the code for the website of Oracle and application worked fxml file!
I'm trying to understand why the code generator of scene triggered an exception?

The difference between the file stage fxml generator and on the oracle Web site is the stage Builder code has < anchor component > as the code on the Oracle's Web site < GridPane >? I couldn't understand how to remove part of anchor in stage Builder and replace it with grid pane?

Your insight is appreciated.
Thank you.
Oh... hmmm... don't specified you event handlers by using the section of Code Inspector?
If you did - check it looks like #someMethodName.
If missing the ' # ', the FXMLLoader he will perform as a script expression - and maybe that's what's causing the exception.

Hope this helps,

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 ().

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:

Hello

Here is simple example how to do it. At the end of the post are a few links that should help you.

package jfx2betatest;

import javafx.collections.ObservableList;
import javafx.geometry.HPos;
import javafx.geometry.VPos;
import javafx.scene.Node;

    // to be simple
    // u can add some methods to add nodes remove nodes etc
    @Override
    public ObservableList getChildren() {
        return super.getChildren();
    }

    @Override
    protected double computePrefWidth(double height) {
        // here calculate prefWidth
        // include padding
        return super.computePrefWidth(height);
    }

    @Override
    protected double computePrefHeight(double width) {
        // here calculate prefHeight
        // include padding and other stuff
        return super.computePrefHeight(width);
    }

    @Override
    protected void layoutChildren() {
        int i = 0;
        for (Node node : getChildren()) {
            layoutInArea(node, i, i, getWidth(), getHeight(), 0.0d, HPos.LEFT, VPos.TOP);
            i += 40;
        }
    }
}

Main class:

package jfx2betatest;

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;

    private Scene scene;
    private Group root;

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        Application.launch(TestDiagonalPane.class, args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {

        root = new Group();

        DiagonalPane dp = new DiagonalPane();
        for (int i = 0; i < 10; i++) {
            Rectangle rect = new Rectangle(50, 50, Color.BLUE);
            rect.setStroke(Color.RED);
            rect.setStrokeWidth(2);
            dp.getChildren().add(rect);
        }

        root.getChildren().add(dp);
        scene = new Scene(root, 500, 500);
        primaryStage.setScene(scene);
        primaryStage.setTitle("DiagonalPane Test");
        primaryStage.centerOnScreen();
        primaryStage.setVisible(true);
    }
}

There are also positionInArea methods in the class of the region.
Maybe someone will after more complex example.

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)

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:

two. TwoPane.fxml

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


<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.BorderPane?>
<fx:root prefHeight="200.0" prefWidth="200.0" type="BorderPane"
         xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">
    <center>
        <Button fx:id="button" layoutX="58.0" layoutY="38.0"
                mnemonicParsing="false" text="Original Text"
                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

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'));

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?

Set content TableView Code does not work when settled on the Initialize method in JavaFX

Hello

I created a new button in the FXML and associated with a method for its Action on. In this method, essentially trying to move everything according to what the controller commissioning of the method (shown in the code below) to the loop (from the part where the row and row1 are declared) to the onAction method so that it displays the contents of the table when you press-, but the compiler gives me this error when I run the program and press the button : "Exception in thread"Thread of Application JavaFX"java.lang.IllegalArgumentException: argument type mismatch."

The main class:

package d1example2;

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

public class D1Example2 extends Application {

   @Override
   public void start(Stage primaryStage) throws Exception {
  primaryStage.setTitle("FXML TableView Example");
   Pane myPane = (Pane)FXMLLoader.load(getClass().getResource("UserInterface.fxml"));
   Scene myScene = new Scene(myPane);
  primaryStage.setScene(myScene);
  primaryStage.show();
   }

   public static void main(String[] args) {
  launch(args);
   }
}

The controller:

public class UserInterfaceController implements Initializable {

The onAction Manager must take a parameter of type ActionEvent, or no parameter (you MouseEvent).

JavaFX binding throws illegal state Exception: not on the thread of Application FX

Hi all
I am updating a label of a task using bindings.
However, when I 'Bind' the label text property with a property of the task, Illegal state exception string is thrown. Saying: this is not not on the thread of JavaFX.
The Exception occurs whenever I try to set the property of the task of the Interior string.
Please do not suggest to use the platform. RunLater(). I want to do this through links as the values I am trying to display in the label (later on) could change too frequently, and I don't want to flood the queue of the thread of the user interface with executable objects.
Please let me know what I'm doing wrong and what I need to change to make it work properly with links. (I'm new to links and concurrency JavaFx API)
Here is my Code.
```

            System.out.println("Creating stringProperty on Thread "+Thread.currentThread().getName());
        }
    };
    private final void setFileString(String value) {
        System.out.println("Setting On Thread"+Thread.currentThread().getName());
        myStringProperty.set(value); }
    public final String getFileString() { return myStringProperty.get(); }
    public final StringProperty fileStringProperty() {

    }
    public static void main(String[] args) {
        launch(args);
    }
}


public class SampleController implements Initializable {

    private Label label;

    @FXML
    private void handleButtonAction(ActionEvent event) {
        System.out.println("You clicked me!");
        myTestService.start(); //This will throw out exceptions when the button is clicked again, it does not matter
    }

    MyService myTestService=new MyService();
    @Override
    public void initialize(URL url, ResourceBundle rb) {
        label.setText("Hello World!");
        //adding the below Line causes the exception
        label.textProperty().bind(myTestService.myTask.fileStringProperty()); //removing this line removes the exception, ofcourse the label wont update.
    } 
}

And it is the output with links on:

If myStringProperty is bound to the textProperty of etiquette, you can only change it on the Thread of the JavaFX Application. The reason is that change its value will result in a change of the label, and changes of live parts of the graphic scene cannot be performed on the Thread of the JavaFX Application.

Task and Service classes expose a messageProperty you could use here. The Task class has a updateMessage (...) method that changes the value of the message on the Thread of the JavaFX Application property. It also merges calls in order to prevent the flooding of this thread. If you could do the following in your MyTask.call () method:
```
updateMessage(""+counter);
```
and then in your controller just do
```
label.textProperty().bind(myTestService.messageProperty());
```
If you don't want to use the messageProperty for some reason any (for example you are already using it for something else, or you want to make something similar to a property that is not a string), you must merge the updates yourself. What follows is based on the source code of the task:
```
public class MyTask extends Task {

     // add in the following:
    private final AtomicReference fileString = new AtomicReference<>();

    private void updateFileString(String text) {
        if (Platform.isFxApplicationThread()) {
            setFileString(text);
        } else {
            if (fileString.getAndSet(text) == null) {
                Platform.runLater(new Runnable() {
                    @Override
                    public void run() {
                        final String text = fileString.getAndSet(null);
                        MyTask.this.setFileString(text);
                    }
                });
            }
        }
    }

   // Now just call updateFileString(...) from your call() method
}
```

How to bind ResourceBundle to FXML that describes the custom control?

What follows is FXML that describes the custom control:
```
<fx:root type="javafx.scene.layout.VBox" xmlns:fx="http://javafx.com/fxml">
  <TextField fx:id="textField"/>
  <Button text="Click Me" onAction="#doSomething"/>
</fx:root>
```
Can we use the resource group as:
```
<fx:root type="javafx.scene.layout.VBox" xmlns:fx="http://javafx.com/fxml">
  <TextField fx:id="textField"/>
  <Button text="%buttonText" onAction="#doSomething"/>
</fx:root>
```
with the choice of locale like ResourceBundle.getBundle ("database name", local); If regional settings are specified in the main Application that uses this custom control.
Thanks for the explanation to anyboby who has related knowledge.

The problem is the synchronization between the local parameter that defines the main application and the locale for the custom control to use in FXML. Thanks for help

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.)

simultaneity and javafx.beans.property

I am building a MVC architecture and I would like to model runs independently of the view/controller, for the model works with the controller/view.

the following example is a very simplified version on how I got it:

controller:

public class controller extends AnchorPane implements Initializable{
     private ObjectProperty<Model> m;
     @FXML Label aLabel;
     
     public controller() throws Exception{
          this.m = new SimpleObjectProperty<Model>(this, "Model", null);
          FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("../view/View.fxml"));
          fxmlLoader.setController(this);
          fxmlLoader.setRoot(this);
          fxmlLoader.load();
     }
     @Override public void initialize(URL arg0, ResourceBundle arg1){}
     public void setGame(Model m) throws Exception{
          this.m.set(m);
          aLabel.textProperty().bind(this.m.get().getIntProperty().asString());
     }
     public void start(){
          //Method1:
          m.get().start();
          //Method2:
          Task<Void> task = new Task<Void>() {
               @Override public Void call() {
                    m.get().start();
                    return null;
               }
          };
          new Thread(task).start();
          //Method3:
          m.get().start();     //Model extends Thread and public void start() to protected void run()
          //Method4:
          m.get().start();     //Model extends Task<Void> and
                         //public void start() to protected Void call() throws Exception
          //Method5:          //calling any of the before ones on the controller that calls this one
     }
}

model:

public class Model extends Thread{
     IntegerProperty intProperty;
     
     public Model(){
          this.intProperty = new SimpleIntegerProperty(0);
     }
     public IntegerProperty getIntProperty(){
          return intProperty;
     }
     public void start(){
          while (true){
               this.intProperty.set(this.intProperty.get()+1);
          }
     }
}

I tried one of those and the results are:
-Method1: the display is blocked and cannot be seen anything (model seems to work since ongoing in the loop)
-Method2: when arrives the first this.intProperty.set (this.intProperty.get () + 1); the task is frozen and stops
-Method3: error running on this.intProperty.set (this.intProperty.get () + 1);
-Remplacement4: same as Method3
-Method5: as before those

How can I make the computer works?

There are a few things wrong here.

First of all, if you want the model to use a wire, make sure that you know how to use the Thread class. There is a decent section on concurrency in the Java tutorial [url http://docs.oracle.com/javase/tutorial/essential/concurrency/index.html]. What you need here, it's that your model class to override the run(), not the start() method method. Call then the start() method, which will cause the run() method run on a separate execution thread. (You can do this in method 3, I didn't understand your comment)

It's probably just an artifact of your simplified version, but your run() method should block at some point. Multiple threads can be run on the same processor, if your current implementation can hog this CPU, it is impossible for the FX Application thread to do its stuff. For the test, throw in a call to Thread.sleep (...), wrapped in a try/catch block for the InterruptedException. I guess the real application expects something from the server, so there would be some "natural" the thread to block in this case.

Important rule for the user interface is that changes made to the interface should be made only on the FX Application thread. Assuming you have the implementation of your model correctly running on a background thread, you violate it with your binding. (The model defines its intProperty on the background thread, the link causes the text of the label to change on the same thread). So to solve this problem your controller should listen to property int of the model changes and schedule a call to aLabel.setText (...) on the FX using Platform.runLater (...) application thread. You want to make sure that you do not flood the Application FX thread with too many such calls. Depending on how often the int in the model property is get updated, you discussed techniques in {: identifier of the thread = 2507241}.

The tasks of JavaFX API provides friendly mechanisms to remind the JavaFX Application thread; However it is not really applicable in this case. The task class encapsulates a one-time job and (optionally) return a value and then ends, which is not what you're doing here.

Here is a complete example; He is not broke in separate FXML for display and a controller, etc., but you can see the structure and break it down according to your needs.

import javafx.application.Application;
import javafx.application.Platform;
import javafx.beans.property.IntegerProperty;
import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;

public class ConcurrentModel extends Application {

  @Override
  public void start(Stage primaryStage) {
    final AnchorPane root = new AnchorPane();
    final Label label = new Label();
    final Model model = new Model();
    model.intProperty.addListener(new ChangeListener() {
      @Override
      public void changed(final ObservableValue observable,
          final Number oldValue, final Number newValue) {
        Platform.runLater(new Runnable() {
          @Override
          public void run() {
            label.setText(newValue.toString());
          }
        });
      }
    });
    final Button startButton = new Button("Start");
    startButton.setOnAction(new EventHandler() {
      @Override
      public void handle(ActionEvent event) {
        model.start();
      }
    });

    AnchorPane.setTopAnchor(label, 10.0);
    AnchorPane.setLeftAnchor(label, 10.0);
    AnchorPane.setBottomAnchor(startButton, 10.0);
    AnchorPane.setLeftAnchor(startButton, 10.0);
    root.getChildren().addAll(label, startButton);

    Scene scene = new Scene(root, 100, 100);
    primaryStage.setScene(scene);
    primaryStage.show();
  }

  public static void main(String[] args) {
    launch(args);
  }

  public class Model extends Thread {
    private IntegerProperty intProperty;

    public Model() {
      intProperty = new SimpleIntegerProperty(this, "int", 0);
      setDaemon(true);
    }

    public int getInt() {
      return intProperty.get();
    }

    public IntegerProperty intProperty() {
      return intProperty;
    }

    @Override
    public void run() {
      while (true) {
        intProperty.set(intProperty.get() + 1);
        try {
          Thread.sleep(50);
        } catch (InterruptedException exc) {
          exc.printStackTrace();
          break;
        }
      }
    }
  }
}
