After reading and using this book, you'll have the authoritative knowledge that should give you an edge in your next JavaFX-based application projects for your job or your clients.

Not only does this book contain comprehensive technical information for developers and designers, it builds a compelling case for choosing JavaFX. Table of Contents 1. Using SceneBuilder to create a User Interface 4. Properties and Bindings 5.

Collections and Concurrency 8. Creating Charts in JavaFX 9. Using the media classes JavaFX 3D Accessing Web Services Actually, under the hood the compiler is capable of optimizing code and able to reduce its footprint. In the same way other languages create closures syntactically, you will also be able to reference them and pass them into other methods.

In order to achieve this ability you will later learn about functional interfaces. Syntax There are two ways to specify lambda expressions. The following simple examples illustrate the general forms: Similar to Java methods, the parentheses are for parameters that are passed into an expression.

Separating the parameter list and the expression body is the arrow symbol. The expression body or code block may or may not be surrounded by curly braces. When an expression is a one-line statement, it is evaluated and returned to the caller implicitly.

Just remember that if the method requires a return type and your code block has curly braces, you must have a return statement. Listing shows two equivalent lambda expressions, with and without curly braces. The compiler will infer the type of the parameters depending on the context. Sometimes for readability you can optionally specify the type of each parameter. If you specify the type, you will be required to surround the list of parameters in parentheses.

One last piece of syntactic sugar is that if you have one parameter to be passed into your lambda, the parentheses can be omitted. Following is a lambda expression that has one parameter event without parentheses. Lambdas and Properties Listing When these nonlocal variables are used in lambda expressions, they need to be immutable.

This is a key principle in the functional programming world. New to the Java 8 compiler is the ability to reference variables outside the scope of an anonymous inner class or lambda expression. When using lambda expressions you can optionally reference variables scoped outside the closure function.

Typically, prior to Java 8 these nonlocal variables needed to be final immutable. This immutable state enables the compiler to better predict program behavior and thus capable of optimizing code. In Java Swing development, this occurred often when variables of the enclosing scope needed to be used inside the scope of an anonymous inner class method local variable scope.

In order to abide by the compiler rules you had to declare a variable as final. The Java 8 compiler has a new capability that will infer the intent of nonlocal variables passed into anonymous inner class methods and lambda expressions to then be converted to final immutable.

To see how we old-school Java Swing developers prior to Java 8 used to receive compile-time errors, please look at Listing The scenario is a button that will modify the text of a Swing JLabel component after the button is pressed.

Prior to Java 8, the code would not compile correctly, because the label variable needed to be declared final. Compile Error! Variable label must be final. Starting with Java 8, you can now make use of the variable capture capability with anonymous inner classes and lambda expressions. Lambdas and Properties 65 Both of the code examples shown in Listing are identical. The difference comes when using a JDK 8 compiler.

When using the Java 8 compiler, the capture variable will implicitly become final immutable , and that will occur without triggering any compilation error. Another way to think about this is to ask questions such as the following: How can I assign a lambda expression to a variable? How can I create a method with parameters that accepts lambda expressions? Functional vs. Imperative Languages The advent of cloud computing has helped to popularize many functional programming languages.

It became apparent there was a paradigm shift in problem-solving that involves extremely large datasets. A typical use case when applying functional programming techniques is the ability to iterate over datasets while performing computations in a distributed fashion so that load can be shared among nodes or CPU cores. In contrast, imperative programming languages gather data to then be passed into a tight for-loop to be processed.

Because of how data and code are coupled, this puts a lot of the burden on one thread core to process so much data. The problem needs to be decomposed to allow other threads cores to participate in the computation, which then becomes distributed. One of the advantages of functional programming is the ability to express functionality in a syntactically concise manner, but more important is the ability to pass functionality lambda expressions to methods.

Being able to pass lambda expressions to methods often fosters the concept of lazy evaluation. The opposite of lazy evaluation is eager evaluation. Using lazy evaluations will often increase performance by avoiding unnecessary calculations. Another important topic to discuss is how functional interfaces are used as closures in the Java language. Simply put, a functional interface is basically a single abstract method SAM.

The idea of functional interfaces has been around for a very long time. For instance, those who have worked with Java threads will recall using the Runnable interface, where there is a single run method with a void return type. As an example of a functional interface, I created an interface called MyEquation with a single abstract compute method.

Once it is created, you can declare and assign variables with a lambda expression. Listing is a functional interface that has a single abstract compute method. Listing demonstrates the assignment of lambda expressions to functional interface variables. Java 8 introduces the new Stream API java. A source can be a reference to data structures such as collections or IO channels.

Such operations allow you to perform aggregate tasks. Aggregate operations are similar to the way spreadsheets can execute some computation over a series of cells, such as formatting, averaging, or summing up values.

To begin using aggregate operations on collections, you will first invoke the default stream method on the java. Collection interface. Stream instance. Lambdas and Properties 67 The common built-in aggregate operations are filter, map, and forEach. A filter allows you to pass in an expression to filter elements and returns a new Stream containing the selected items. The map operation converts or maps each element to another type and returns a new Stream containing items of the mapped type.

For instance, you may want to map Integer values to String values of a stream. A forEach operation allows you to pass in a lambda expression to process each element in the stream. A typical use case to exercise the three common aggregate operations would be this: Listing implements the use case, which exercises various aggregate operations. Following is the output from Listing Next, it outputs the original list of elements unmodified.

Then the code declares a nonlocal variable to the lambda expression called threshold, to be used in a filter expression. Next, we obtain a stream from the values collection via stream method to perform aggregate operations. The next operation is the sorted method, which sorts elements that were returned from the filter method stream. Continuing the method chaining, notice the map operation.

The map method operation is able to map each element in the stream from one data type to another. Lambdas and Properties In this scenario the stream elements are Integer objects, which are mapped to String objects. In this example the string elements are hexadecimal values.

Finally, the forEach operation iterates over each element in the stream of string hex elements to be printed. To clarify, the idea of method chaining actually comes from the fluent interface pattern for API design. Default Methods Default methods are a new way to add default implementation methods to Java interfaces. Default methods have the effect of adding extending new behavior to interfaces without breaking compatibility.

Default methods are not abstract methods but methods having implementation code. For example, adding new methods to Java interfaces can affect all implementation classes. Because of the strict contract of Java interfaces, the compiler forces the implementer to implement abstract methods, but classes that implement interfaces with default methods do not force the developer to implement those default methods.

Rather, derived classes will acquire the behavior of the default method implementation. An Example Case: Listing is the default method stream in the java. Collection interface from the Java 8 source code. The cat kind or species can easily demonstrate default behavior that is found in some cat kinds and not others. For instance, the great cats such as lions, tigers, and jaguars are able to roar, and smaller cats can purr. Also, a house domestic cat is able to meow.

Lambdas and Properties 69 Figure Both tigers and lions have the same behavior can roar via the default roar method from the Roarable interface.

With both having the same functionality in two places, later down the road things could become a major maintenance nightmare. Code for the Example To see the class diagram in Figure implemented as code, refer to Listings through To implement the class diagram I will briefly outline the three parts of the code example.

First is the set of cat interfaces with default method behaviors. Second are the concrete cat classes such as Lion, Cheetah and HouseCat.

Last is the main example application, which demonstrates default methods in action. Lambdas and Properties 71 Listing The Main Application File Mixins. Lambdas and Properties mediumCat. Tiger with striped fur. Tiger is eating. Tiger is sleeping. Tiger is walking.

Cheetah is eating. Cheetah is sleeping. Cheetah is walking. Domestic Cat is eating.

Best Books to Help You Learn JavaFX

Domestic Cat is sleeping. Domestic Cat is walking. These interfaces provide behavior for any derived class that wants to pick and choose mixin common behaviors. You will notice that the main interface Cat contains abstract methods getCatKind , getFurDescription , and default methods walk , eat , and sleep.

As usual, the Java compiler will enforce classes implementing the Cat interface to implement the abstract methods getCatKind and getFurDescription. The default methods on the Cat interface have implementation code that serves as functionality for all cats. These default methods will provide behavior to the Cat interface while also centralizing functionality implementation for all derived classes.

I created empty marker interfaces Roarable, Purrable, and Meowler, which contain respective default methods roar , purr and meow. These interfaces are similar to the idea of a mixin, which in object-oriented languages allows developers to extend or add default behavior to any derived class or interface.

Listing is the main class that begins by creating three cat objects: Tiger, Cheetah, and HouseCat. It invokes all of the methods on each cat object. Listing shows a cat of type Tiger with all of its methods being invoked. Properties allow developers to add listener code to respond when the wrapped value of an object has changed or is flagged as invalid.

Also, property objects can be bound to one another. Binding behavior allows properties to update or synchronize their values based on a changed value from another property. Depending on who you talk to, you might get different explanations; however, these concepts all address the issue of how best to handle synchronization between the model and view.

What this means is that when a user interacts input with the UI view the underlying backend data store the model is automatically updated, and vice-versa. Without trying to oversimplify the concepts, I will refer you to the actual UI patterns that are involved. Because these patterns have been heavily discussed over the years, the JavaFX team has designed and implemented APIs to overcome problems that arose with these UI scenarios.

In this section you will be learning how to use JavaFX properties and bindings to synchronize between your GUI and your data objects. Properties Before the JavaFX properties API, Java Swing developers adhered to the JavaBean convention specification , which specifies that objects will contain privately scoped instance variables which have associated getter accessor and setter mutator methods.

For instance, a User class might have a private instance variable password of type String. The associated getter and setter would be the getPassword and setPassword methods, respectively. Listing shows a User class that follows the older JavaBean convention.

In other words, if the getter method were named getPwd , the property would be named pwd and would have nothing to do with the attribute named password. The JavaBeans specification also provided an API that has the concept of property change support java. PropertyChangeSupport , which allowed the developer to add handler listener code when the property changed. At the time, this solved only part of the issue of property change support.

Although the JavaBeans API became a standard way to build domain objects, it still lacked robust ways to synchronize the domain models and views within a GUI application as described earlier.

Through the years the JavaBean specification and API gave rise to many third-party tools and frameworks to ease the developer experience. However, wiring up GUI components to JavaBeans using unidirectional or bidirectional binding still got pretty complicated.

At times, developers would have resources that were not properly released, which led to object leaks. Developers quickly realized they needed a better way to bind and unbind GUI controls to be wired up to properties. There are two types to be concerned about: All wrapper property classes are located in the javafx. Listed here are commonly used property classes. To see all of the property classes, please refer to the documentation in Javadoc. SimpleBooleanProperty javafx.

ReadOnlyBooleanWrapper javafx. SimpleIntegerProperty javafx. ReadOnlyIntegerWrapper javafx. SimpleDoubleProperty javafx. ReadOnlyDoubleWrapper www. Lambdas and Properties javafx. SimpleStringProperty javafx.

Pro JavaFX 2

To create a string property that is capable of both readable and writable access to the wrapped value, you will use the javafx. SimpleStringProperty class. Listing is a code snippet that demonstrates an instance of a SimpleStringProperty class and modifies the property via the set method. Thus, referencing a StringProperty exposes fewer methods of the implementation class SimpleStringProperty.

You will later discover other convenient constructor methods when working with JavaBeans and Property objects. In the case of reading the value back, you would invoke the get method or getValue , which returns the actual wrapped value String to the caller.

To modify the value you simply call the set method or setValue by passing in a string. Read-Only Properties To make a property read-only you would use the wrapper classes that are prefixed with ReadOnly from the javafx. To create a property to be read-only you will need to take two steps. First is to instantiate a read-only wrapper class and invoke the method getReadOnlyProperty to return a true read-only property object.

Listing creates a read-only string property. Lambdas and Properties 77 This code snippet actually takes two steps to obtain a read-only string property. You will notice the call to getReadOnlyProperty , which returns a read-only copy synchronized of the property. One property is read-only and can be passed to external users. The other property is read- and writable and should be used internally only.

From a security perspective you should be aware of the proper steps to create a true read-only property. In the process of rewriting the bean I also wanted to add an additional read-only property called userName to demonstrate the read-only property behavior. Listing shows the User class rewritten to use JavaFX properties. The File User.

Similar to the JavaBean property change support, JavaFX properties have constructors that will allow you to specify the bean itself, its property name, and its value. As a simple example, Listing shows the instantiations of a read-only and a read-writable property using the JavaFX property change support-based constructors.

But most of all, when dealing with property change support, you will need access to the bean and its other properties. Making the getter and setter final prevents any derived classes from overriding and possibly changing the underlying property. Property Change Support Property change support is the ability to add handler code that will respond when a property changes. JavaFX property objects contain an addListener method.

This method will accept two types of functional interfaces, ChangeListener and InvalidationListener. Recall that functional interfaces are single abstract methods which are expressed using the Java lambda syntax. All JavaFX properties are descendants of the ObservableValue and Observable interfaces method overloading , which provide the addListener methods for ChangeListener and InvalidationListener, respectively. One last thing to point out is that it is important to clean up listeners by removing them.

To remove them you will invoke the removeListener method by passing into it a referenced named listener as opposed to an anonymous inner class or anonymous lambda expression. Listing shows how to create a ChangeListener to be registered with a property. Lambdas and Properties 79 Listing shows how to create an InvalidationListener to be registered with a property.

In the Javadoc documentation, the difference between a ChangeListener and InvalidationListener is described as follows: An invalidation event is generated, if the current value is not valid anymore.

This distinction becomes important, if the ObservableValue supports lazy evaluation, because for a lazily evaluated value one does not know if an invalid value really has changed until it is recomputed. For this reason, generating change events requires eager evaluation while invalidation events can be generated for eager and lazy implementations.

When using the ChangeListener, you normally want eager evaluation such as the validation of properties on a form-type application. When you access the observable value, it causes the InvalidationListener to be eager.

Binding Simply put, binding has the idea of at least two values properties being synchronized. This means that when a dependent variable changes, the other variable changes.

JavaFX provides many binding options that enable the developer to synchronize between properties in domain objects and GUI controls. In this section you will learn about three binding strategies when binding property objects. To bind a property to another property, you will invoke the bind method. This method will bind in one direction unidirectional. For instance, when property A binds to property B the change in property B will update property A, but not the other way.

A bound value cannot be set. Listing is a Contact bean having a property firstName that is bound bidirectionally to a local variable fname of type StringProperty. The fluent APIs are methods that allow you to perform operations on properties using English-like method names.

For example, if you have a numeric property, there would be methods like multiply , divide , subtract , www. Lambdas and Properties 81 and so on. Another example would be a string property having methods like isEqualTo , isNotEqualTo , concat , and similar. As an example, Listing shows how to create a property that represents the formula for the area of a rectangle.

IntegerExpression parent interface. This example binds by using the multiply method, which returns a NumberBinding containing the computed value. For all available fluent interfaces, please see the Javadoc for javafx. Listing shows how to create a low-level binding for the formula for the volume of a sphere. Next, I want to close out this chapter with an example showing how to build a snazzy-looking logon dialog window that makes use of shapes, lambda expressions, properties, and bindings with a hint of UI controls.

Shown in Figure is the initial display of the logon dialog window the code will create. Initial display of the logon dialog window Following are the instructions for interacting with the application.

The user will have three attempts to enter the correct password. Figure shows the user making the first attempt to log on. The user is entering the password into the logon dialog window 2. As the user enters the password, they have an opportunity to hit the Enter key.

If the password is incorrect, a red X appears to the right of the password text field. Figure shows an invalid logon. The user has pressed Enter with an invalid password 3.

If the user types the correct password in real time a green check appears. After the green check appears, the user may hit the Enter key to be granted access. Figure shows the user entering a valid password.

Lambdas and Properties 83 Figure Pos; import javafx. PasswordField; import javafx. BOLD, 30 ; userName. Lambdas and Properties 85 passwordField. When the password is incorrect, the visible property becomes false, which hides the green check node SVGPath. Lambdas and Properties 87 In the start method, a User object is created to be used as the domain object model to be synchronized with the GUI form.

Next, the stage is set to be transparent by invoking the Stage. This will allow us to create translucent and irregularly shaped windows without the decoration of the native OS title bar. After initializing the stage, I also needed to create a Scene with a root node of type Group that will allow me to add child nodes.

Even though the root node is transparent, it will need to be the same size as our logon screen. The text node is set up with a 30 point SanSerif font having a fill color of the foregroundColor white variable. Shown in Figure in the upper-right corner of the logon dialog window is the padlock icon.

Recall that in Chapter 2 we discussed generating complex shapes using path elements to create an ice cream cone, as depicted in Figure To render a path the string representing the path notation is passed into the setContent method on the SVGPath node.

To see how to use SVG paths, visit http: There I was able to obtain very nice SVG icons, at http: Next, the code creates an HBox as a container for the first row row1 to hold the userNameCell and padLock nodes.

After creating the first row, the code proceeds by creating the PasswordField UI control. I added a 20 point SanSerif font to the password field. Next, the code will set the prompt text to let the user know what to type into the field. The CSS style I applied to the password field was a white background with opacity of 80 percent. Still working with the password field, I used the fluent interface subtract to bind the preferred width to subtract 55px to allow room for the stack pane that contains the granted and denied icons.

Next, I create two more icons using the SVGPath node that represents an X and a check mark, denoting denied deniedIcon and granted grantedIcon access icons, respectively. These icons will be placed in a StackPane layout node.

The StackPane layout allows child nodes to be stacked, hence the name. In this scenario the deniedIcon and grantedIcon nodes are stacked on top of each other.

This trick will allows us to flip between icons using the setVisible method. As a whole stack pane node, it will be positioned to the right of the password field. Next, the code continues by wiring up the UI controls and adding property change support ChangeListeners to various properties. The code proceeds with the passwordField by adding an action as a functional interface for the method setOnAction when the user hits the Enter key.

The following handler code is set on the password field when the user hits the Enter key. User cdea is granted access. Lambdas and Properties 89 Still working with the password field, I added a change listener to listen for keystrokes from the user. As the user types into the password field the password is compared against the stored hardcoded password. Finally, I added the last bit of wiring for when a user has too many failed attempts.

The rest is assembling the rows into a VBox layout and adding it to the root node for the scene to be shown. You were introduced to the new features in Java 8 such as lambda expressions, stream APIs, and default methods. Starting with Java lambdas, you were able to learn the syntax and make use of functional interfaces. Next, you were able to use the stream API and common aggregate functions. After an example of using the stream APIs to manipulate elements in a collection, you then learned how to extend behavior on Java interfaces with default methods.

With a solid understanding of working with properties, you then learned about various binding strategies. With the increase of the number different screen sizes a UI developer will need to learn how to create applications with UI layout management in mind. After layouts are discussed in the first half of this chapter an example will be presented showing a form-based application. The form-based application demonstrates the resizing of child UI controls as the parent window is being resized.

JavaFX UI controls include menus, menu items, list views, table views and progress indicators. Layouts One of the greatest challenges in building user interfaces is the laying out of UI controls onto the display area. In GUI applications it is ideal to allow the user to resize a viewable area while UI controls also resize in order to provide a pleasant user experience. Following are the JavaFX layouts discussed in this section: HBox javafx. VBox javafx. FlowPane javafx.

BorderPane javafx. GridPane 91 www. As child nodes are added consecutively, each is appended to the end right side. When the parent node is not resizable a Group node, for example , the row height of the HBox takes on the height of the child node with the greatest preferred height. Also, by default each child node aligns to the top-left Pos. The HBox can be configured to have resizing ranges to allow the parent to manage and calculate space available upon layout requests. Although in this chapter you will learn how to set constraints using a programmatic approach, there are also alternative strategies.

One well known and preferred strategy is to style or set constraints using JavaFX CSS attributes; you will catch a glimpse of that approach later in this chapter, and more details in Chapter 6, on custom UIs. In contrast, when using resizable nodes such as a TextField control, the parent has the ability to manage and compute the available space for the TextField to grow horizontally.

JavaFX - Wikipedia

Nonresizable nodes such as rectangle shapes are used in the example to demonstrate the many spacing attributes for the HBox layout control. For brevity, only the relevant code is listed here.

The HBoxExample. Layouts and UI Controls 93 Figure The output of the file HBoxExample. This constructor takes a value of type double, which specifies the horizontal space in pixels between child nodes. This is also the equivalent of invoking the setSpacing method.

The figure displays three gray rectangular areas, each five pixels wide, that represent the spacing between child nodes r1 to r4. Notice that the inner part of the HBox border has yellow padding one pixel wide surrounding the row.

An example of an HBox layout containing four rectangles After creating all four rectangles, the code sets the margin on rectangle r1. The code creates an Insets object with a margin of two pixels for the top, right, bottom, and left. As shown in Figure , this is the surrounding space around rectangle r1 blue. When the parent of the HBox is a Group node not resizable , the HBox width will total 76 pixels and the height 22 pixels.

As children are added, each is placed beneath the previous child node. VBox layouts can also be configured to have resizing ranges to allow the parent node to manage and calculate space available upon layout requests. To demonstrate the use of a VBox, the example in Listing contains the same four rectangles from the previous example, with the same layout constraints.

The VBoxExample. The output of VBoxExample. Figure depicts horizontal gray bars that represent the spacing between child nodes r1 to r4. After constructing the VBox, you set the padding via setPadding method. Setting the padding by using an Insets object allows you to create padding between the border and the row.

Notice in Figure the VBox padding of one pixel surrounding the VBox shown surrounded by a yellow line. Layouts and UI Controls 95 Figure VBox containing four rectangle child nodes Once the four rectangles are created, the code sets the margin on the rectangle r1. To set the margin we use the static method VBox. The code then creates an Insets object with a margin of two pixels for the top, right, bottom, and left. Surrounding rectangle r1 is a two-pixel margin shown in blue.

Depicted in Figure are four child nodes flowing from left to right and then wrapping. A FlowPane layout with nodes flowing left to right with the ability to wrap nodes based on horizontal space. The Hello text node is wrapped to the next line because the available horizontal space, denoted by the dashed line, is too small By default a FlowPane layout flows child nodes from left to right Pos.

To change the flow alignment, you can simply invoke the setAlignment method by passing in an enumerated value of type Pos. Listing creates a FlowPane layout to flow child nodes from right to left Pos. BorderPane The BorderPane layout node allows child nodes to be placed in a top, bottom, left, right, or center region. Because each region can only have one node, developers typically nest layouts. An example would be to create an HBox with children to then be set as the top region via the setTop method.

Layouts and UI Controls 97 Figure The BorderPane layout This layout is similar to many websites we see every day, where navigational links are placed in either the top, bottom, left, or right regions of a page, while the main content is in the center area. The left and right border regions take up the available vertical space between the top and bottom borders.

According to the Javadocs, the default alignment of nodes when placed in the top, bottom, left, right, and center regions is as follows: For instance, business applications typically have data entry form screens. Forms usually have read-only labels on the first column and input fields on the second column, resembling a grid pattern.

For example, if the second column contains input text fields, you may want them to resize as the window is being resized.

The most interesting part of the example is the use of column constraints on the GridPane. Column constraints apply a minimum and maximum horizontal width for the child nodes to grow or shrink as the window is resized. To address the need for tuning applications on a specific class of devices, the JavaFX 1. From the point of view of the end user "Drag-to-Install" allows them to drag a JavaFX widget or application residing in a website and is visible within the browser window and drop it onto their desktop.

The application will not lose its state or context even after the browser is closed. An application can also be re-launched by clicking on a shortcut that gets created automatically on the user's desktop. This behavior is enabled out-of-the-box by the Java applet mechanism since Java 6 update 10 and is leveraged by JavaFX from the underlying Java layer. Sun touts "Drag-to-Install" as opening up of a new distribution model and allowing developers to "break away from the browser".

The plug-ins generate JavaFX Script code that preserves layers and structure of the graphics. Developers can then easily add animation or effects to the static graphics imported.

There was also an SVG graphics converter tool also known as Media Factory that allows for importing graphics and previewing assets after the conversion to JavaFX format. JavaFX Mobile 1. This concept makes it possible to share code-base and graphics assets for desktop and mobile applications. Through integration with Java ME , the JavaFX applications have access to capabilities of the underlying handset, such as the filesystem , camera, GPS , bluetooth or accelerometer.

An independent application platform built on Java, JavaFX Mobile is capable of running on multiple mobile operating systems, including Android , Windows Mobile , and proprietary real-time operating systems. Sun planned to enable out-of-the-box support of JavaFX on the devices by working with handset manufacturers and mobile operators to preload the JavaFX Mobile runtime on the handsets.

In May Sun Microsystems announced plans to deliver JavaFX for the browser and desktop by the third quarter of , and JavaFX for mobile devices in the second quarter of Sun also announced a multi-year agreement with On2 Technologies to bring comprehensive video capabilities to the JavaFX product family using the company's TrueMotion Video codec. Major releases since JavaFX 1. Update releases typically do not have a release name.

Oracle announced their intention to stop shipping JavaFX with JDK 11 and later, [13] and it's no longer bundled with the latest version. This release introduced: This version named Presidio [12] was released on October 10, This release introduced:.

Various improvements have been made within the JavaFX libraries for multithreading. The Task APIs have been updated to support much more concise threading capabilities i. In addition, the scene graph has been designed to allow scenes to be constructed on background threads and then attached to "live" scenes in a threadsafe manner. Linux support was added with JavaFX 2. On April 27, , Oracle released version 2. On August 14, , Oracle released version 2. JavaFX 8 adds several new features, including: Oracle wrote in a white paper that JavaFX new fixes will continue to be supported on Java SE 8 through March and announced that they are "working with interested third parties to make it easier to build and maintain JavaFX as a separately distributable open-source module.

The following is a rather simple JavaFX-based program. It displays a window a Stage containing a button. From Wikipedia, the free encyclopedia. Application ; import javafx. ActionEvent ; import javafx. EventHandler ; import javafx.
