What is JavaFX? | Detail about JavaFX
Since, JavaFX is using for creating and delivering desktop applications that those applications can run on devices, as well as Internet applications.
JavaFX is the next version of Swing to replace it as the standard GUI library for Java SE, but both are planned for the future. The JavaFX favors desktop computers and web searching on Microsoft Windows, Linux, and macOS.
JavaFX Mobile 1.x applications can be made in the same language, JavaFX Script, JavaFX 1.x applications for the browser or desktop, and using the JavaFX SDK and JavaFX Production Suite.
This concept allows you to share codebase and graphical assets for desktop and mobile applications. By integrating with Java ME, JavaFX applications can access key phone features such as file system, camera, GPS, Bluetooth, or accelerometer.

Java FX Features
Built-in UI controls
JavaFX with Eclipse
Now you need to configure Eclipse to run JavaFX applications. There are two ways to install Eclipse. We can install JavaFX jar files or install new software directly.
The figure below shows the full architecture of the JavaFX platform. There are many components interconnected to each other. JavaFX includes a wide range of interfaces for creating compatible Internet applications on many platforms.
JavaFX public API
JavaFX Application Structure
The JavaFX application consists of three main components, called scene, view, and node. All JavaFX applications must import the JavaFX. application.Application classes. This provides lifecycle methods for the JavaFX application.
- Firstly, public void init
- Secondly, public abstract void start (Stage primaryStage)
- Thirdly, public void stop
JavaFX 2D Shapes
In some applications, we need to show the user a two-dimensional shape. However, JavaFX gives you the flexibility to create 2D images on your screen.
There are several classes in our classroom that use 2D forms. All of these classes are in the JavaFX.scene.shape package.
Create 2D shapes
In the JavaFX.scene.shape package represents a different shape.
Follow these instructions to make a two-dimensional shape.
- Initiate the respective class : As for example, Rectangle rect = new Rectangle()
- Set the desired properties for the class using setter methods
- Add a class object to the Group layout
Commonly, a line is a geometric structure that joins two points (X1, Y1) and (X2, Y2) in the X-Y coordinate axis. JavaFX allows developers to create a line in a graphical interface thanks to the JavaFX application. The JavaFX library represents the Line as part of the JavaFX.scene.shape package.
Create a Line
Follow the instructions below to make a Line.
- Instantiate the class javafx.scene.shape.Line.
- set the desired properties of the class object.
- Add the class object to the group
In general, a rectangle can be defined as a geometric figure made of four sides, the opposite sides of which are always the same, and the angle of the next two sides is 90 degrees. A rectangle with four equal sides is called a rectangle.
The JavaFX library allows developers to create rectangles by moving the class JavaFX.scene.shape.Rectangle.
A circle is a special type of ellipse with two axes in the same position. The horizontal radius is the same as its vertical radius.
JavaFX allows us to create a circle in the GUI of any program by creating a class JavaFX.scene.shape.Circle. Set class properties using instance customization methods and add a class object to the group.
The effects are mainly actions aimed at improving the graphics. JavaFX is a package called JavaFX.scene.effect. There are several classes in the UI where you can apply effects such as shapes and images to graphical components. Their main points are compressed in the table below.
Transformation is a change in the shape, character or appearance of graphics. In JavaFX, a package called JavaFX.scene.transform offers all the conversions.
The table contains lessons for different conversions. A class called JavaFX.scene.transform.Transform is a parent class for all conversion classes.
In general, animation can be defined as a transition that forms a myth of the motion of an object. This is a set of modifications that are applied sequentially to an object to show how the object moves.
This can be done by quickly showing brands. JavaFX has all the classes for applying animation to nodes in the JavaFX.animation package. All classes in this package extend the JavaFX.animation.Animation class.
JavaFX 3D Shape
JavaFX allows us to create three-dimensional images. The JavaFX.scene.shape package contains defined classes that offer all methods for working with 3D forms. Such classes are Box, Cylinder, and Sphere. The Shape3D class JavaFX.scene.shape is the base class for all JavaFX 3D classes.
Create 3D shapes in JavaFX
1. We want to create 3D respondents immediately.
2. Mark the properties of the class. For example
3. Place the camera at the scene. you do not need to set the camera to create a 3D effect, but it does provide a certain position for the camera view. You can do this as follows.
4. Add a box to the graphic view and set the Properties according to Scene and Scene.
JavaFX UI Controls
This part of the tutorial will give you an in-depth knowledge of JavaFX UI controls. The graphical interface of any desktop application mainly takes into account UI elements, layout, and order.
UI elements are items that are displayed to the user for interaction or information exchange. Location Specifies the location of UI elements on the screen. Behavior is the response of a UI element to an event.
The JavaFX.scene.control package allows Button, Label, etc. for UI components. provides all the necessary classes such as. Each class represents a specific UI control and defines a number of methods for its style.
In general, a cart can be defined as a graph or chart that represents data as a symbol. Graphs are mainly used to represent large amounts of data and the relationship between data sections.
We can create different graphs to represent different information. In JavaFX, we can create the charts by using the classes provided by the package javafx.scene.chart.
Types of charts
- Pie Chart: In a pie chart, the sectors in a circle are used to represent different proportions of general information. JavaFX classjavafx.scene.chart.PieChart is used to work with a pie diary. We will discuss the PieChart in more detail later.
- XYChart: In XYChart, information is represented on the XY (horizontal and vertical) axes. The X-axis represents one value type and the Y-axis represents another value type. A comparison is made between the values shown in the X and Y diagrams to show the correct information. JavaFX is used to process the javafx.scene.chart.XYChart class with XYChart.
Types of Axis
- Category Axis: The category axis is used to represent another category of information. This is an axis of different values, as the exact values are not displayed on the category axis.
In JavaFX, the class javafx.scene.chart.CategoryAxis is the focus of this category. To create a category axis, we need to start this class immediately.
2. Number Axis: The number shaft is used to indicate the exact range of values. In JavaFX, the class javafx.scene.chart.NumberAxis represents a value axis. All we need is to accelerate to create a numerical axis.
CSS (Cascading Style Sheets) is a design language used to improve the appearance of web pages without changing their functionality. Therefore, this is only due to the presentation of the web page in the web browser.
CSS in JavaFX
JavaFX, a new generation UI library allows you to configure the theme of the program. Afterall, the javafx.css package includes all classes of the CSS application in the JavaFX application.
Applying CSS to JavaFX is similar to applying CSS to an HTML page. In this tutorial, we’ll look at style rules and printing steps in JavaFX.
Media with JavaFX
In today’s world, rich Internet applications need to be able to play and edit multimedia files. JavaFX offers a rich API that can play audio and video on demand.
The JavaFX Media API allows users to access audio and video in rich Internet applications (RIA). Hence, the JavaFX Media API can distribute multimedia content to a TV, mobile phone, tablet, and many other devices.
In this part of the textbook, we explore the ability of JavaFX to work interactively with media files. To do this, JavaFX offers the package JavaFX.scene.media, which contains all the necessary classes. JavaFX.scene.media has the following classes.
JavaFX Event Handling
JavaFX gives us the flexibility to create many different applications for desktop applications, web applications, and graphics applications.
In current applications, users play a key role in launching the application properly. In most cases, the user must interact with the application.
Types of Events
1. Foreground Events
Previous events are primarily the result of the user interacting directly with the GUI application. For example, pressing a button, pressing a key, selecting an item from a list, scrolling a page, and so on.
2. Background Events
Background events do not require interaction with the user application. Therefore, these events are mainly caused by operating system interruptions, crashes, shutdowns, etc.
