Demo on JavaFX
This document provides an overview of JavaFX presented by Mansi Babbar. It discusses what JavaFX is, why it is needed, its features and structure. The key components of JavaFX like controls, layouts, charts, media etc. are explained. An example JavaFX application structure and code is given. The presentation ends with a demo of JavaFX.

- 5. What is JavaFX? ●Library used to build Rich Internet Applications (RIA). ● Applications can run consistently across multiple platforms. ● Applications can run on various devices. ● Can develop GUI applications effectively with rich content.
- 6.
- 7. Need for JavaFX ●No need of using various libraries to add features such as Media, UI controls, Web, 2D and 3D, etc. JavaFX includes all these features in a single library. ● Developers can access the existing features of Java libraries such as Swing. ● Compared to Swing, it provides a clear and clean architecture and features many enhancements: styling, event management, transitions, scene graph, etc. ● Provides all the professional Java tooling required to debug, analyze, profile, and log a client application.
- 8. Need for JavaFX ●Enables a simple app-like installation on the client side, without any prerequisites. ● Provides a rich set of graphics and media APIs. ● Provides the possibility of developing up-to-date user interfaces with animations, multitouch, etc. It also provides interfaces to combine graphics animation and UI control.
- 9. Experiences with JavaFX ●Stability ● Standard control library ● Extensibility ● Third-party libraries ● Development process ● Performance ● Support
- 10.
- 11. Features of JavaFX ●Written in Java ● Support FXML ● Provides WebView ● Swing Interoperability ● Built-in UI controls ● CSS like Styling ● Swing Interoperability ● Integrated Graphics library ● Support Media ● Provides JavaScript Engine

- 14. JavaFX Application Structure 1.To construct the UI: a. Prepare a scene graph. b. Construct a scene, with the root node of the scene graph. c. Setup the stage with the constructed scene.
- 15.
- 16. Stage ● A stageor window contains all the objects of a JavaFX application. ● It is represented by Stage class of the package javafx.stage. ● The primary stage is created by the platform itself. ● A stage has two parameters determining its position namely Width and Height. ● It is divided as Content Area and Decorations (Title Bar and Borders). ● There are five types of stages available − ○ Decorated ○ Undecorated ○ Transparent ○ Unified ○ Utility ● You have to call the show() method to display the contents of a stage.
- 17.
- 18. Scene ● A scenerepresents the physical contents of a JavaFX application. ● It contains all the contents of a scene graph. ● The class Scene of the package javafx.scene represents the scene object. ● At an instance, the scene object is added to only one stage. ● Size of the scene can be specified by passing its dimensions (height and width) along with the root node to its constructor.
- 19.
- 20. Scene Graph ● Ascene graph is a tree-like data structure (hierarchical) representing the contents of a scene. ● All visual components (controls, layouts etc.) are part of scene graph. ● Scene graph components must be attached to a scene to be displayed, and that scene must be attached to a stage for the whole scene to be visible. ● The total object graph of all the controls, layouts etc. attached to a scene is called the scene graph.
- 21.
- 22. Nodes ● A nodeis a visual/graphical object of a scene graph. ● All nodes are subclasses of a JavaFX class called javafx.scene.Node. ● A node may include − ○ Geometrical (Graphical) objects (2D and 3D). ○ UI Controls such as − Button, Checkbox, Choice Box, Text Area, etc. ○ Containers (Layout Panes) such as Border Pane, Grid Pane, Flow Pane, etc. ○ Media elements such as Audio, Video and Image Objects.
- 23. Type of Nodes ●Root Node − The first node of scene graph is known as the root node. ● Branch Node/Parent Node − Node with child nodes. ○ The abstract class named Parent of the package javafx.scene is the base class of all the parent nodes. ○ Those parent nodes will be of the following types − ■ Group ■ Region ■ WebView ● Leaf Node − Node without child nodes. ○ For example - Rectangle, Ellipse, Box, ImageView, MediaView, etc.
- 24.
- 25. Controls ● Provide somekind of control functionality inside a JavaFX application. ● For a control to be visible it must be attached to the scene graph of some Scene object. ● Nested inside some JavaFX layout component that manages the layout of controls relative to each other. ● Event handlers can be added to controls to perform some event when the control is fired.
- 26. Controls JavaFX contains thefollowing controls: ● Accordion ● Button ● CheckBox ● ChoiceBox ● ColorPicker ● ComboBox ● DatePicker ● ListView ● Menu ● MenuBar ● PasswordField ● ProgressBar ● RadioButton ● Slider ● SplitMenuButton ● SplitPane ● TableView ● TabPane ● TextArea ● TextField ● TitledPane ● ToolBar ● TreeTableView ● TreeView ● Label ● Spinner ● ToggleButton
- 27. Layouts ● Components whichcontains other components inside them. ● Manages the layout of the components nested inside it. ● Called parent components because they contain child components. ● Layout components are subclasses of the JavaFX class javafx.scene.Parent. ● Must be attached to the scene graph of some Scene object to be visible.
- 28. Layout components ● BorderPane ●StackPane ● TilePane ● GridPane ● AnchorPane ● TextFlow ● JavaFX contains the following layout components: ● Group ● Region ● Pane ● HBox ● VBox ● FlowPane
- 29. Other Components ofJAVAFX ● Charts ○ JavaFX comes with a set of built-in ready-to-use chart components to avoid coding charts from scratch every time you need a basic chart. ● WebView ○ JavaFX contains a WebView component which is capable of showing web pages (HTML5, CSS etc.). ● Audio ○ JavaFX contains features that makes it easy to play audio in JavaFX applications. This is typically useful in games or educational applications.
- 30. Other Components ofJAVAFX ● Video ○ JavaFX contains features that makes it easy to play video in JavaFX applications. This is typically useful in streaming applications, games or educational applications. ● 2D Graphics ○ JavaFX contains features that makes it easy to draw 2D graphics on the screen. ● 3D Graphics ○ JavaFX contains features that makes it easy to draw 3D graphics on the screen.

- 32. JavaFX by Example JavaFXis huge, with 36 packages. These are the commonly-used packages: ● javafx.application: JavaFX application ● javafx.stage: top-level container ● javafx.scene: scene and scene graph. ● javafx.scene.*: control, layout, shape, etc. ● javafx.event: event handling ● javafx.animation: animation
