    Study Notes

    JavaFX Overview

    • JavaFX is a framework for creating graphical user interfaces (GUIs) in Java.
    • Three frameworks are available for building GUIs in java: Standard Widget Toolkit (SWT), Swing, and JavaFX.
    • SWT directly accesses the native GUI libraries of the operating system.
    • Swing provides a richer set of GUI components than SWT, accessing the low-level OS drawing routines directly using Java2D.
    • JavaFX is designed for desktop and mobile applications, as well as web browsers and web start applications. It is the successor to swing.

    JavaFX IDE Setup

    • NetBeans provides a "What You See Is What You Get" (WYSIWYG) feature by default.
    • Eclipse requires an additional plugin for WYSIWYG functionality. JavaFX libraries are .jar files and not included with the JDK. Download them from https://gluonhq.com/products/javafx/. Add the libraries like external jars.
    • e(fx)clipse and Scene Builder are popular options for Eclipse. Scene Builder downloads are available at gluonhq.com/labs/scene-builder/.
    • Use the same version of Java, JavaFX, and Scene Builder for compatibility.
    • Install Swing plugin for Eclipse: WindowBuilder (not often used).

    JavaFX Installation and Setup

    • Download the appropriate JavaFX SDK for your operating system.
    • Extract the SDK.
    • Add the JavaFX library to the project in your IDE (like Eclipse) in the same way you add external libraries.

    Java VM Arguments

    • Add the following arguments to your VM (for Java) for Windows:
    • -module-path “C:\your\javafx\path\lib” --add-modules=javafx.controls --add-modules=javafx.fxml. Linux and Mac use '/'.
    • For Mac, replace '' with '/' in paths.

    IntelliJ and JavaFX

    • Use IntelliJ with JDK 21 or higher for creating JavaFX projects.

    Setting up Scene Builder in IntelliJ

    • Open IntelliJ Preferences - Languages & Frameworks > JavaFX.
    • Set the path to Scene Builder.

    JavaFX Controls

    • JavaFX offers various UI components (like Labels, Buttons, Radio Buttons, Checkboxes, and more).

    JavaFX Layout

    • Layout pans are essential for arranging UI elements. Several layout panes are provided in JavaFX, each with different functions:
    • VBox (Vertical Box)
    • HBox (Horizontal Box)
    • FlowPane (Handles Layout)
    • GridPane (Grid Layout) and others

    JavaFX FXML

    • The information for creating the GUI in JavaFx is saved in an XML File (FXML file).

    JavaFX CSS

    JavaFX Nodes

    • JavaFX applications consist of nodes which form the scene graph. There are several types, which may act as branch or leaf nodes. Some include:
    • Group
    • Circle
    • Rectangle
    • Region.
    • Text
    • Image
    • View

    JavaFX Basic Steps

    • Create a JavaFX application stage for one or more scenes.
    • Create a Scene for different GUI components to interact.
    • Create the GUI components.
    • Use variables and classes to represent the state of GUI elements.
    • Set up event handlers for user interaction with the GUI elements.
    • Implement animations.

    JavaFX A Blank Window

    • Creating a simple JavaFX window requires extending the javafx.application.Application class and implementing the start() method.

    JavaFX A Window with Animation

    • Animate JavaFX components using transition, timeline attributes, and techniques like translate, rotate, fill, scale, and parallel transitions.

    Hello World Window

    • Create simple applications by creating custom GUI using JavaFx programming to interact with event handlers.

    Different Layout (Out of the Box)

    • Various built-in layout panes provide flexible arrangements for GUI elements.

    GridPane

    • Grid panes are used for specific arrangements within a JavaFX application.

    Styling FX Buttons with CSS

    • Applying different styles to buttons using CSS to modify component look and feel.

    JavaFX CSS Reference

    Create a JavaFx GUI with FXML

    • Create a graphical layout by using Scene Builder and FXML for structure. Save information to a FXML file.

    Creating a Java GUI Using FXML

    • Parse, and use FXML, initialize JavaFX components. Link GUI components to the controller.

    Assign the correct Id to every Component

    • Assign IDs to UI elements that are referenced in the controller classes.

    Implement the Click Action in the Controller

    • Implement the action trigger in the Controller class using event handlers.

    Assign the Method to the Component

    • Assign methods to the GUI elements.

    General Notes

    • Refer to official JavaFX API documentation. Specifics may vary in documentation, IDE, and Java version. Implement Java in your preferred IDE.
