Edition

This control supports the online edition of values, and this section attempts to provide an overview of the available API and how you should use them.

First of all, the cells most often requires a different user interface than when a cell is not being edited. It is the responsibility of the Cell implementation used. For TreeTableView, it is strongly recommended that edition is per-TreeTableColumn , rather than per row , as more often than otherwise you want users to change the value of each column differently, and this approach allows for specific to each column publishers. It's your choice, if the cell is constantly in a State of change (for example, this is common for CheckBox of the cells), or to switch to a different user interface when editing begins (for example when a double click is received on a cell).

To find out what changes were requested on a cell, simply substitute the Cell.startEdit() method and update the cell text and graphic properties as appropriate (for example to set the null text and set the graphics to be a TextField ).

In addition, you must also override Cell.cancelEdit() to reset the user interface to its visual state of origin when the installation ends. In both cases, it is important that also ensure you that you call the method super for that cell to perform all the duties he has to do for his edit mode or its output.

Once your phone is in a State of change, the next thing you are probably interested is how to validate or cancel the current editing. It is your responsibility as a cell factory supplier. Your implementation of cell will know when the editing is complete, based on user input (for example when the user presses ESC or enter keys on their keyboard). When this happens, it is your responsibility to call Cell.commitEdit(Object) or Cell.cancelEdit() , as the case may be.

When you call Cell.commitEdit(Object) an event is fired to the TreeTableView, you can observe by adding a EventHandler via TreeTableColumn.setOnEditCommit(javafx.event.EventHandler) . Similarly, one can also observe edit events for edit start and edit cancel .

By default, the validation Manager TreeTableColumn edit is not null with a default manager who is trying to replace the property value for the item in the currently-being-edited line. It is able to do this as the Cell.commitEdit(Object) method is passed to the new value, and this should be transferred to the validation Manager change via the CellEditEvent , which is triggered. It is simply a matter of calling TreeTableColumn.CellEditEvent.getNewValue() to retrieve this value.

It is very important to note that if you call TreeTableColumn.setOnEditCommit(javafx.event.EventHandler) with your own EventHandler , then you will remove the default handler. Unless you then manage writeback in the property (or the relevant data source), nothing will happen. You can work around this by using the TableColumnBase.addEventHandler(javafx.event.EventType, javafx.event.EventHandler) method to add a TreeTableColumn.EDIT_COMMIT_EVENT EventType with desired EventHandler as the second argument. Using this method, you will not replace the default implementation, but you will be notified when a validation of the change has occurred.

I hope this summary answers some of the most frequently asked questions. Fortunately, JavaFX comes with a number of pre-built cell plants that handle all the requirements of editing on your behalf. You can find these cell factories pre-built in the javafx.scene.control.cell package.

Transparent edges on the buttons? JavaFX (CSS)

I would be grateful if someone could share how to get rid of the button edges, or at least they are transparent in .css (using JavaFX). Im trying to recreate the Windows 10 calculator
The following code does not work
button {}
-fx-background-RADIUS: 0;
-fx-border-color: transparent;
}

Thank you!

You should look at modena.css, you can find it inside the jfxrt.jar of your JRE installation.

Import javafx.application.Application;
Import javafx.geometry.Insets;
Import javafx.scene.Scene;
Import javafx.scene.control.Button;
Import javafx.scene.layout.StackPane;
Import javafx.stage.Stage;

SerializableAttribute public class boutonAfficher extends Application {}

@Override
public void start (final stage) bird Exception {}

Button = new Button ("Button");
Presentation of StackPane = new StackPane (button);
layout.setPadding (new Insets (10));
button.setStyle)

"shadow - fx - highlight-color: transparent;" + / / If you do not want evidence of 3d effect.
"- fx - outside-border: transparent;" + / / If you do not want a border of the button.
"inner - fx - border: transparent;" + / / If you do not want a border of the button.
"focus - fx - color: transparent;" + / / If you do not want a focus ring.
"- fx - faint-focus-color: transparent;" + / / If you do not want a focus ring.
"base - fx -: palegreen;" + / / If you want a shady button gradient which lightens the overview and go on armament.
"body - fx - color: palegreen;" + / / instead of - fx-Basic, if you want a flat shaded button which do not alleviate the hover and pounce on armament.
"police - fx - size: 80px;"
);

stage.setScene (new Scene (layout));
internship. Show();
}

Public Shared Sub main (String [] args) throws Exception {}

Launch (args);
}

JavaFX Desktop.getDesktop () .browse (Linux)

People;
in our JavaFX application, we include buttons that are supposed to begin some web pages in the internal applications using Desktop.getDesktop () .browse (...). If this works well on Windows machines, it seems to fail in a strange way on GNOME / Linux systems. Result: whenever I click one of these buttons, the application just freezes and must manually be killed. Using the debugger, I managed to go as far as XDesktopPeer.browse (...) but here the application does not seem to pass, I can't not step away, but I also do not seem to have sources at hand for this to see what exactly is happening here. Ideas, anyone?
TIA and good luck,
Kristian

Could you try with .getHostServices () .showDocument () instead and see if it fares better than AWT Desktop support?

Also with regard to the Office of the AWT, check your code if Desktop.Action.BROWSE is supported before attempting to open the URL?

The ball in javafx graphics

I'm working on a project where I need to use a graphic of the ball. Are there any card ball already developed? Can you please share whatever it is? Or at least the idea of creating graphics custom, so that I can create my own?
Thanks in advance.

Here's a quick and dirty implementation. It has not been completely tested and there are probably a lot of things to improve:

Need help that implements the service class (JavaFX competition)

I hope I'm not double posting, if so? My apologies...

I create a small application in which you can run several algorithms that can be run and analyzed visually. So far, it runs great with errors now (as far as the GUI goes). When I run problems, this is after I implemented my bottom Threading code that the GUI will no longer appear. I followed the instructions until the 't' and although I have not compile errors (build Succeeded) I get without user interface.

This is how I implemented it:

 private Service<Void> backgroundThread;
    
    private Stage stage;
    
    
    
    @Override
    public void initialize(URL url, ResourceBundle rb) {
        // TODO
    }  


    public void init(Stage stage) {
        this.stage = stage;
    }
     
   
    @FXML
    public void browseInputFile(ActionEvent event){
       FileChooser fileChooser = new FileChooser();
       fileChooser.setTitle("Open text file");
       fileChooser.setInitialDirectory(new File(System.getProperty("user.home")));
       fileChooser.getExtensionFilters().addAll(
               new FileChooser.ExtensionFilter("Text Files", "*.txt"),
               new FileChooser.ExtensionFilter("All Files", "*.*")
       );
       
        File file = fileChooser.showOpenDialog(stage);
        
        if(file != null){
            TInputField.setText("Choosen File: " + file); 
           // TerminalOut.setText(readFile(file));
        }
        
    }
    @FXML
    private String readFile(File file){
        StringBuilder stringBuffer = new StringBuilder();
        BufferedReader bufferedReader = null;
        
        try{
            
            bufferedReader = new BufferedReader(new FileReader(file));
            
            String text;
            while ((text = bufferedReader.readLine()) != null){
                stringBuffer.append(text);
            }
                
        }catch (FileNotFoundException ex) {
               Logger.getLogger(Quick_SortFX.class.getName()).log(Level.SEVERE, null, ex);
        }catch (IOException ex) {
               Logger.getLogger(Quick_SortFX.class.getName()).log(Level.SEVERE, null, ex);
        } finally { 
            try{
                bufferedReader.close();
            } catch (IOException ex) {
                Logger.getLogger(Quick_SortFX.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
            return stringBuffer.toString();
    }
     
    
    @FXML
    public void runProgram(ActionEvent event){
        
       backgroundThread = new Service<Void>() {
     
        @Override
        protected Task<Void> createTask(){
            return new Task<Void>() {
                
                @Override
                protected Void call() throws Exception{
              
                //this is where I put the algorithm code
                for(int i = 0; i<=10000; i++){
                    updateMessage("i: " + i );
                }
                
                    return null;
                }
            };
        }
    };
           
           backgroundThread.setOnSucceeded(new EventHandler<WorkerStateEvent>(){
               
               @Override
               public void handle(WorkerStateEvent event){
               System.out.println("Done! ");
               TerminalOut.textProperty().unbind();
               }
       });
       
       TerminalOut.textProperty().bind(backgroundThread.messageProperty());
       
       backgroundThread.restart();
  
    }

And even if no compilation error I get nothing. Recently, I was able to look at the example for class of service on the web site of Oracle and it is very different and a bit more confusing, that I have already but I have does not work. Can someone please tell me what I'm doing wrong?

That is the message the compiler gives me:

How to open a local file using JavaFX?

Is there something similar with the code below?

---------------------------------------------------------------

java.awt.Desktop import;

.............

try {}

Desktop.getDesktop () .the (new File(\\file_to_open.extension_file));

}

catch (IOException ex)
{

}

............

So the final code might be something similar to:

button.setOnAction(actionEvent -> {
  FileChooser dialog = new FileChooser();
  dialog.setTitle("Open Resource File");
  dialog.getExtensionFilters().setAll(new ExtensionFilter("PDF Files", "*.pdf"),
      new ExtensionFilter("Text Files", "*.txt"));
  File file = dialog.showOpenDialog(mainStage);
  if (file != null) {
      myApplication.getHostServices().showDocument(file.toURI().toString());
  }
});

JavaFX 8 - way reasonable to make a canvas to fill its parent

This here is the essence of a problem with a canvas that I have right now
public class Test extends the Application
{
Public Shared Sub main (String [] args)
{
Launch (args);
}
@Override
public void start (point primaryStage)
{
TabPane tabPane = new TabPane();
Tab = new Tab ("Tab");
tabPane.getTabs () .add (tab);
BorderPane borderPane = new BorderPane();
tab.setContent (borderPane);
Canvas MyCanvas = new MyCanvas();
borderPane.setCenter (canvas);
canvas.setWidth (500);
canvas.heightProperty () .bind (borderPane.heightProperty ());
Scene = new scene (tabPane, 1300, 800);
primaryStage.setScene (scene);
primaryStage.show ();
}
MyCanvas class extends Canvas
{
public MyCanvas()
{
this.widthProperty () .addListener (evt-> draw());
this.heightProperty () .addListener (evt-> draw());
}
private void draw()
{
Double width = getWidth();
double height = getHeight();
System.out.println (width + ";" + height);
Context GraphicsContext = getGraphicsContext2D();
context.clearRect (0, 0, width, height);
context.setFill (Color.GREENYELLOW);
context.fillRect (0, 0, width, height);
}
}
}
The interesting line is
canvas.heightProperty () .bind (borderPane.heightProperty ());
This works only at halfway, when the window expands the draw functions, that all are called, but when the window is more tiny draw function is not called.
Now, I thought that maybe I should go higher up in the hierarchy.
canvas.heightProperty () .bind (tab.? tab has no heightProperty
A more?
canvas.heightProperty.bind (tabPane.tabPane.heightProperty ());
Now this seems good (it works when it gets bigger or smaller), until you realize that it will be always at least 29 big pixels (at least on my system)
The reason is that the header is the pixel 29 missing. But I don't see a way to get the size of the header of the tabPane. Now, I could just subtract the tabPane.heightProperty 29, but it won't work that on my system, it might be a different size on other systems or javafx could change.
I looked at a few other ways to get a resizable canvas, but things like the creation of a custom component and only put the canvas substituting the layoutChildren method seems more like a hack of a proposed solution.
I would really appreciate a way to resize my paintings on request, without going any further than the parent of my canvas (borderPane in my case).

You can use something like this to make a resizable canvas.
```
public final class CanvasPane extends Region {

    private final Canvas delegated = new Canvas();

    public CanvasPane() {
        getChildren().add(delegated);
        delegated.widthProperty().addListener(observable -> draw());
        delegated.heightProperty().addListener(observable -> draw());
    }

    @Override
    protected void layoutChildren() {
        super.layoutChildren();
        final double width = getWidth();
        final double height = getHeight();
        final Insets insets = getInsets();
        final double contentX = insets.getLeft();
        final double contentY = insets.getTop();
        final double contentWith = Math.max(0, width - (insets.getLeft() + insets.getRight()));
        final double contentHeight = Math.max(0, height - (insets.getTop() + insets.getBottom()));
        delegated.relocate(contentX, contentY);
        delegated.setWidth(contentWith);
        delegated.setHeight(contentHeight);
    }

    private void draw() {
        final double width = delegated.getWidth();
        final double height = delegated.getHeight();
        final GraphicsContext gc = delegated.getGraphicsContext2D();
        gc.setFill(Color.GREENYELLOW);
        gc.fillRect(0, 0, width, height);
    }
}
```
Also, it is really unnecessary to link anything because you set this control within a BorderPane: it is automatically resized to the dimensions of the central area.

You can create a similar class for a resizable ImageView.

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 use my FXML SceneBuilder.

My starting point is:

Scene = new Scene (root);

stage.setScene (scene);

internship. Show();

}

Public Shared Sub main (String [] args) {}

Launch (args);

}

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)

Public access to the JavaFX Jira?

Hello world
Surely I'm missing something obvious but... Does anyone know how to get the JavaFX Jira? : https://javafx-jira.kenai.com
I need to create an account? Where?
Thank you
Marc

Hey mark,.

Missing probably not something obvious. My guess is that they stopped allowing automatic registration for the current tracker. The independent instance of JIRA you accessed is deleted and JavaFX bugs are migrated to JBS. The target date for the migration to complete is June 5. After that bugs can anonymously view-through JBS:

https://bugs.OpenJDK.Java.NET/secure/dashboard.jspa

There are 2 ways to submit bugs in the JBS system.

(1) If you have an author JBS status, you will have an account JBS and can submit bugs directly.

(2) any person may submit bugs via the Bug database.

I just checked and it seems that there already is an option to choose JavaFX when using bugs.java.com. If you submit a bug, you might try it. I have not used yet, so if you submit a bug, I'd be interested to hear how it works. Ex: What kind of confirmation you get, how there are mapped in JBS, do you get notifications by e-mail updates, etc. ?

If you are looking for a specific bug, I don't see a way to view them at the present time. All existing bugs will be added to the JBS, and after migration, should be accessible via the bug current IDs. There's more info here:

Make JavaFX alerts look like ControlsFX dialogue

Hello
is there a way to make the official dialogue boxes (alerts) 8u40 looks like ControlsFX dialog boxes?
I am talking mainly about the black title bar and slightly "generic" gray (who appear to be white in alert javafx?) as seen here:
http://controlsfx.BitBucket.org/org/controlsfx/dialog/dialogs.html
Thank you

ControlsFX dialog boxes are deprecated,

See the following blog announcement:

Announces ControlsFX 8.20.7 / / JavaFX News, demos and Insight / / FX experience

Use rather openjfx-dialog boxes:

https://BitBucket.org/controlsfx/openjfx-dialogs

This project is the controlsfx dialog box (probably the style you want), the features implemented on top of the new API of the Java 8u40 dialog box.

Dialogs in the basic platform do not natively have the ability to return at your leisure without improvements that (I assume) are in openjfx-dialogues.

----

I looked inside and I assumed wrong, openjfx-dialogue just seems to be a copy of the Java8u40 API dialog box so it has all the features of the obsolete ControlsFX dialog boxes.

I guess your best bet to get the dialog boxes works the way you want is to use the deprecated ControlsFX API dialog box.

Directly contact the developers of ControlsFX if you have any other questions.

https://groups.Google.com/Forum/?hl=en#! controlsfx/forum-dev

I see the currently last post is titled 'The plan for the dialogues'... it reads:

(4) the existing dialogs API in ControlsFX will be deprecated but not

deleted. This API will be removed when we planned on JavaFX 8u40. If

you use the ControlsFX dialog boxes, please take the time to transition away from

the old API as soon as possible. If there are things that you could do once

Now you can't, please file bugs, but please note that we will not

bring all the features (for example I'm sorry to say that I won't be

bring back the light dialog boxes unless someone puts a big bag of

money).

JavaFX 8 node dynamic scaling

I'm trying to implement a scene with a ScrollPane in which the user can drag around a knot and resize it dynamically. I'm moving and scaling with the mouse wheel work as well as a zoom reset.

Here's my question:

I have a problem with the calculations to suit the width of the parent node.

If I Zoom in or out, the width adjustment does not work.

If I change the size of the window after execution of fitWidth() once, the width adjustment does not the second time.

Here is my code as a NBS and how it works...

1 (works) mouse wheel will zoom in and out around the mouse pointer

2 (works) or press left mouse to drag the rectangle autour

3 (work) left, double-click to reset the zoom

4. (does not) double-clicked right to fit the width

My calculations to reposition the rectangle at the top left of the pane and mount it (i.e., resize it upwards or downwards) to the width of the parent are incorrect.

I found the answer. I was looking at the wrong calculations, assuming that it be linked to translation. The real culprit was the calculation of the difference in scale. I just changed this:

double f = (scale / oldScale)-1;

to do this:

double f = scale - oldScale;

in the fitWidth() method, thus producing this...

    public void fitWidth () {
        double scale = getParent().getLayoutBounds().getMaxX()/getLayoutBounds().getMaxX();
        double oldScale = getScale();

        double f = scale - oldScale;

        double dx = getTranslateX() - getBoundsInParent().getMinX() - getBoundsInParent().getWidth()/2;
        double dy = getTranslateY() - getBoundsInParent().getMinY() - getBoundsInParent().getHeight()/2;

        double newX = f*dx + getBoundsInParent().getMinX();
        double newY = f*dy + getBoundsInParent().getMinY();

        setPivot(newX, newY, scale);

    }

manipulate multiple windows in javafx (window inside the window)

Hello everyone,
I'm new to javafx I start using it instead of swing, I used the scene generator for my forms the problem that I have encountered, I don't know how to have a main screen with the menu up and function bar to select it in the menu, it will open other windows and these window must be inside my window like for example netbeans.
I don't need to open the new window in separate that I need all the windows inside my main window and control on them to minimize maximize maybe please help.

I found a way to solve my problem

It's jfxtra library

Chart JavaFX color Changing axis

I'm fighting to change the color of the axis X and Y. I can change the color of the ticks and tick in CSS labels... But not the axis themselves. Can anyone help?

Define your own css stylesheet and who substitute the appropriate values that have been created in the default modena.css.

So for the lower axis of green color:

{.axis:bottom}

-fx-border-color: transparent green transparent transparent;
}

Modena.CSS is inside the javafx - src.zip delivered with your JDK implementation.

If you look, you can find the rules of style for the axes:

/*******************************************************************************

* *
* Axis *.
* *
******************************************************************************/

. Axis {}

AXIS_COLOR: derive(-fx-background,-20%);
-fx-tick-label-font-size: 0.833333em; / * 10px * /.
-fx-tick-label-filling: drift (text - fx - background-color, 30%);
}

{.axis:top}

-fx-border-color: transparent AXIS_COLOR transparent transparent;
}

{.axis:right}

-fx-border-color: transparent AXIS_COLOR transparent transparent;
}

{.axis:bottom}

-fx-border-color: transparent transparent transparent AXIS_COLOR;
}

{.axis:left}

-fx-border-color: transparent AXIS_COLOR transparent transparent;
}

. Axis: Top > .axis-label.
. Axis: Left > .axis-label {}

-fx-padding: 0 0 4px 0;
}

. Axis: Bottom > .axis-label.
. Axis: Right > .axis-label {}

-fx-padding: 4px 0 0 0;
}

. Axis-graduation,
{.axis-minor-graduation

-fx-fill: null;
-fx-stroke: AXIS_COLOR;
}

How to charge the screen when changing languages in JavaFX 2?

I am a beginner with javaFX and need to change the language of the screen... but I have no idea how to do to recharge the screen when the language has been changed. The application has a button where to have the language available. I just want to refresh screen when the user changes language.
Here is the start method to show the scene.
@Override
public void start (steps) throws exceptions
{
Stage = this.stage;
Locale locale = Locale.getDefault ();
Rb ResourceBundle = ResourceBundle.getBundle ("resources/Label", local);
loader = new FXMLLoader (getClass () .getResource ("FXMLDocument.fxml"), rb);
root = (Parent) loader.load().
FXMLDocumentController controller = loader.getController ((FXMLDocumentController));
controller.setMain (this);
scene = new Scene (root);
stage.setScene (scene);
internship. Show();
}
Here is the function to change the language (in the same class with start function), the rb is the new ResourceBundle:
public void refresh (ResourceBundle rb)
{
change the language here
}
1. I don't want to use the resourceBundle to get the value in the resource file, and set the label in a scene of one.like following:
this.btnLabel.setText (rb.getString (key.test));
...
2. I don't want to reload the scene as follows:
public void refresh (ResourceBundle rb)
{
VR;
{
loader = new FXMLLoader (getClass () .getResource ("FXMLDocument.fxml"), rb);
root = (Parent) loader.load().
scene.setRoot (root);
FXMLDocumentController controller = loader.getController ((FXMLDocumentController));
controller.setMain (this);
}
catch (exception Err)
{
err.printStackTrace ();
}
}
While we have a solution to just define the resourceBundle and recharge the easier scene?
Thank you and best regards!

JAVAFX isn't that kind of solution (more efficient and automatic)?

No and nor Swing or AWT (no idea for SWT): whenever you manually change the value of all labels autour (or build a custom system to do as suggested). The easiest way that most of the app use is simply to save the language in preferences and then ask the user to restart the application. So when the computer reboots, the app is full new regional settings. On the change of the fly is another matter.

Note: there is no FXML binding as far as i18n and text labels are concerned. You can just describe them as being located by using the '%' symbol, and at load time, the FXMLLoader has made an extra effort to replace anything out of all values (see the method resolvedPrefixedValue() in the class FXMLLoader source code simply call resources.getString ())... and that's all. There is more no link between controls text properties and the bundle once finished loading (and that's why you can replace everything that follows when in the controller when you want).

Another option would be to create your own custom FXMLLoader keeps the autour bundle and create links to i18n labels at load time.,.
