We are currently doing the bi directional property binding in the java code, but it would be nice to declare those bindings at the point where the UI Controls are created, ie in our FXML files.
I understand bi-directional binding of the form
value="#{controller.path.propertyName}" was removed from JavaFX 2.1
Will it be put back in 2.2?
I'm using binding into fxml:
<Button fx:id="btnSalva" defaultButton="true" mnemonicParsing="false" disable="${controller.busy}"
onAction="#salva" prefHeight="57.0" prefWidth="141.0" styleClass="text-bold" text="Salva" />
Controller is my controller that extends another class from which it inherits busy property.
I see that fxmlloader only looks into the bottom class and not in superclasses, don't know if it's voluntarily or a bug.
I can't figure out how using binding on selectionModelProperty in a ListView that is using MULTIPLE selection model. I want bind my bean in which I've a list of item A and the selection of that items into the List.
ListView<A> listView; listView.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
My bean return a ReadOnlyListProperty<A>
So I don't know how do:
listView.selectionModelProperty().bindBidirectional(bean.getItems());
I want to synchronize a List<String> with the selected items of a ListView. In the real project, I want to synchronize the selected items of a TreeView and the selected images of a galery (custom control).

In most cases, the program works as expected but sometimes there are some issues.
- For example, when I launch the application and select all the items with Ctrl-A, the event { [One, Two, Three] added at 0, } is fired so the list of strings contains incorrectly 4 elements [One, Two, Three, One].
- Another example, when selecting all the items (with Shift+End), two events are fired { [One] removed at 0, } and { [One, Two, Three] added at 0, }, that's correct. But when I remove the last element with Shift-Up, 3 events are fired { [Two] removed at 1, }, { [Three] removed at 2, } and { [Two] added at 1, } and an exception is thrown:
java.lang.IndexOutOfBoundsException: toIndex = 3

I used the SceneBuilder to create an applications and it works quite well. Now I got a problem to set the pref. size of a ScrollPane to the size of the app.
I want to install a binding between the scroll pane's pref. size and the stage's pref. size. Since the scroll pane field reside in the FXMLController class I need a way to access this field.
I'm new in JavaFX world. I'm going to write an application using FXML and this application will use embedded database. Is there any tutorial or example showing how to connect FXML (using controller as I expect) with database. I'm using Hibernate with classic JAva - is it possible to work with Hibernate with JavaFX?
View Replies View RelatedI have created an application in SceneBuilder, and want to call a pop up (also created separately in scene builder) when a certain button is pressed. How?
View Replies View RelatedIs it possible to validate the input of a TextField that ist bound to a Property before both values are updated? Following is an example of my problem .....
In my model, there is a SimpleDoubleProperty discount. As you can see, there is some validation logic in the method setDiscount that might be used by other parts of the model.
public class Model {
private DoubleProperty discount = new SimpleDoubleProperty();
public DoubleProperty DiscountProperty() {
return discount;
[Code] ....
My Main class has a Textfield that is bound to the discount-property, a button to put the current value of the discount-property to console and a button to call the setDiscount-method ......
public class Main extends Application {
@Override
public void start(Stage primaryStage) {
try {
Model model = new Model();
BorderPane root = new BorderPane();
Scene scene = new Scene(root,100,100);
[Code] .....
By using the bidirectional Binding between the TextField and the discount-Property, the setter in the model is never called and therefore there is no validation of the input value. When calling the setter programatically with the second button, everything works as expected.
I experimented with neglecting the Binding and using ChangeListeners for both the TextField and the discount-Property but only produced infinte loops when both listeners triggered each other alternating.
I'm making a tic tac toe program. Currently I have a welcome screen for my tic tac toe game, once the button is clicked I want the main game to open. I have created two FXML VBox windows created from JavaFX Scene Builder. I want to know how to close the welcome menu and launch the 2nd FXML window.
This 2nd FXML window will have it's own controller where the tic tac toe calculations will be held.
Here is the event listener on when the mouse action is performed on the button
@FXML
private void startGame(ActionEvent event) {
}
I have an FXML table view. And I want to assign value from an tableview create on class to FXML tableview. But at the end is not displaying data.
Example:
@FXML private TableView fxmlTable;
private TableView insideClassTable;
public class SomeClass
{
public SomeClass(){
insideClassTable = new TableView();
//////////////////////////////////////////////////
Filling insideClassTable with data.
//////////////////////////////////////////////////
fxmlTable= insideClassTable;
}
// some other code and main
}
If I set value to fxmlTable, data are display correctly, but if assign value to insideClassTable first and then make fxmlTable=insideClassTable they are not display.
recently I've started using javafx and I wonder if there a way to combine FXML layouts without Java code, like insert smaller layout into bigger one?
View Replies View RelatedWhenever I use a control inside an .fxml file like:
<Label></Label>, <TableView></TableView>, etcera ...
I get an exception for example:
Label is not a valid type., TableView is not a valid Type., etcera
This exception I then solve with placing an import tag inside the .fxml file.
However as I do not know each import name, I have to look this up like writing down:
Label label = new Label();
inside a class and then place my cursor on it to see which import name Eclipse generates.
This import name i then put inside the .fxml file with <? import ?> beginning and end tags with question marks around it.
Is there anyways to automatically generate these import tags inside an .fxml file even if you don't know the import name for the control you want to use?
I have a TextArea that I am trying to restrict user inputs to allow only IP addresses format in that Area. So I thought of only allowing digits and decimal points. For multiple IPs, One IP per line, the TextArea needs to accept new lines. For the most part what I have below is working except for delete. I can't delete any entry even if I am using the associate Unicode. Is this even the correct way of doing it?
public class RestrictIpInputTextArea extends TextArea {
@Override
public void replaceText(int i, int il, String string){
if(string.matches("[0-9_u000A_u232B_u0008_u2421_._u007F_u005F]") || string.isEmpty()){
super.replaceText(il, il, string);

I have a multi scene JavaFX FXML application [URL] ....
I have added a TextField to Scene2.fxml and Scene3.fxml files each scene has its own Controller Class with a ScreensController class that loads a HashMap with Id name, Node screen that is defined in the ScreensFramework
class (Main class)
public void addScreen(String name, Node screen) {screens.put(name, screen);}
So each time you click a Button on a screen (scene) you fire an ActionEvent and move to another screen
myController.setScreen(ScreensFramework.screen2ID);
What I would like to do if it is possible is use the value in the TextField on Sceen2 and transfer it to the TextField on Scene3. I have discovered that unless both FXML files are loaded this is so far not possible. This is a desktop application. So how do you create a variable that is GLOBAL and has a life after one class is unloaded or one FXML file is unloaded?
At this point I do not want a database to accomplish this task.I have developed in Visual Basic 6 where I would just declare a global variable that could be used through out the application.
I am trying to figure out the best way to load localized versions of FXML content. I know that I can localize strings, images etc. by specifying a ResourceBundle when loading the FXML using FXMLLoader with a ResourceBundle. But what about if you need to tweak the FXML for different locales (eg, adding more real estate for certain elements, different fonts, etc). Is there any way to create localized versions of FXML content? The only thing I can come up with is a naming convention like MyForm.fxml, MyForm_de_DE.fxml, ... and trying to load them based on the locale, but I'd have to come up with my own fallback for specific locales that aren't found.
View Replies View RelatedI need to create dynamic Layouts that are created from java source code, using JAXB. As FXML does not have a schema, this gets me in trouble.
Scene Builder cannot be used for dynamic Layouts, but if there really is no schema I could use, maybe someone knows how Scene Builder generates the fxml files.
I got a strange (!?) behavior using an FXML annotated object ...
Consider the following:
You got an app with FXML build UI.
There is a button called connectB which is @FXML annotated...
In the initialize method of my app I disable this button.
After the startup of my app I want to connect to a DB ...
Therefore I use an Task<Void>
I put everything together in one class ( the main application class )
Here is the code...
public class MainApp extends Application implements Initializable{
// ... several other objects
@FXML
private Button connectB;
@Override
public void initialize( URL location, ResourceBundle resources ) {
connectB.setDisable( true );
[Code] .....
The connectB is not null in the initialize method but later in the task class ....
Lets say I have a desire to convert and entered value to Centigrade or Fahrenheit and that I have two Radio Buttons to designate the type of conversion with the Answer posted to a TextField on Scene Two from a button click event on Scene One ok Now I would like to convert the value in the TextField on Scene Two to Kelvin and reflect the value on Scene Three in a TextField by clicking a button on Scene Two
lets say I have 4 FXML files sceneONE sceneTWO and scenMain and I created 4 controllers ControllerONE and MasterController
So far I can navigate to the different scens with just the MasterController code below...
BUT because I have two FXML files I can not capture the value in the first FXML file and pass it to the second scene
This project is my attempt to adapt the FXML style code from this web site
Switching to Different Screens in JavaFX and FXML | JavaFXTutorials
Which uses this code to switch scenes
//get reference to the button's stage stage=(Stage) btnS1.getScene().getWindow();
//load up OTHER FXML document
root = FXMLLoader.load(getClass().getResource("ATTwo.fxml"));
But will not permit variable transfer due to scope of variables which reside in two different FXML files
public class MasterController implements Initializable{@FXML public Button btnS1;
@FXML public Button btnS2;
@FXML public Label lblS1;
@FXML public Label lblS2;
@FXML public TextField txfS1;
@FXML public TextField txfS2;

dynamically create tabs by pressing a button, each tab has Primefaces input texts in which i'll be adding stuff and with a Submit button i'm submitting the form.
My issue now is this; although I can create more buttons through my managed bean, I cannot set the ValueExpression to the InputTexts. When I do:
inputName.setValueExpression("value", createValueExpression("#{cdiBean.name}",String.class)); it doesn't work.
The createValueExpression is a static method in my managed bean and it returns a ValueExpression. I'm most certain I found it online, not sure where though, it's been over a month since the last time I worked with this topic.
Anyway, is my whole "methodology" correct? Should I do anything differently?
I have a question regarding static binding and dynamic binding. Say for example we have below hierarchy,
class Animal
{
public void eat() {
System.out.println("Animal Eating");
}
}
[Code] .....
1) a.eat(); // Prints Animal eating ---> Static Binding 2) a.eat(); // Prints Dog eating ----> Dynamic Binding
Static Binding means,compiler will be able to decide which method to call based on class type of reference variable at compile time.That is compiler will check whether method is available or not in class.
Dynamic binding means,at runtime JVM will run the method implementaton,based on the object which reference variable is pointing.
So basically compiler will check class type of reference variable and at runtime JVM will check what type of object reference variable is pointing.
Here my my doubt is , in below both cases,that is
1) a.eat(); // Prints Animal eating ---> Static Binding
2) a1.eat(); // Prints Dog eating ----> Dynamic Binding
At compile time,compiler will check whether method is available or not in class. Since eat() method is available ,then in both cases it should be Static binding. or at run time if JVM decides which method implementation to call,then JVM will check which object the reference variable is pointing,then in above 2 cases also JVM will check in Animal object and Dog object for the method eat(). Since eat() method available then both should be dynamic binding.
I am getting doubt on what parameters/conditions we are deciding which is static binding and which is dynamic binding .
Will compiler will check the type of reference variable and also type of object at compile time and when it is ambiguous it leaves the decision to JVM?
Or is it like if method call and method implementation belong to same class then it is static binding and if method call and method implementation belong to different class in same inheritance hierarchy then dynamic binding.
I have an editable JTable that has a lot of JComboBox's as cell entries. I would like to be able to "arrow over" to said cell, and with a pressing of either a numerical button or by typing the first letter of the String selection (possibly followed by a second), be able to select the appropriate selection from the cell's JComboBox. I have tried to add a key listener to the JComboBox itself, which works given that I click on said cell and show its menu.
How would I go about ensuring that, when focus is on the cell itself, and I start typing, the appropriate selection is chosen?? (I think this might get into key binding, but I don't know if I have to try it from the scope of JTable, or from that JTable's TableModel (which I have made my custom version of).
Here is what I have so far (everything but SandwichNumber, SandwichName, and Oregano uses JComboBox): [URL] ...., how would I do such key binding?
My program TestBind0 (code below) tries to find/create a registry and bind an object.
Find/create: it first tests if there is already a registry on that port; if not, then it tries to create one.
The program tries to find/create the registry on ports 40654, 50876, 30321, 33445, 1099, in this order, until it succeeds in both creating the registry and binding the object. Why does TestBind0 throw for each attempt

Why is the equals-method in the super-class invoked? Shouldn't the equals-method in the sub-class be invoked(at least in the first if-statement since b2 is a B(i know B is also an A))?Is the equals-method overridden? Or does B have its own equals-method?
class SomeClass{
public static void main(String[] args) {
B b1 = new B(123,1);
B b2 = new B(123,2);
