Study Notes

Introduction to GUI

A Graphical User Interface (GUI) provides a user-friendly way to interact with applications.
GUIs are built from components called controls or widgets, which users interact with using the mouse, keyboard, or other input methods like touch and voice recognition.

Java GUI Libraries

Java's original GUI library was the Abstract Window Toolkit (AWT), suitable for simple GUIs but not comprehensive projects.
Swing, a more robust and flexible library, replaced AWT and became Java's primary GUI technology.
JavaFX is a modern GUI platform that replaced Swing, offering a comprehensive API for GUI, graphics, and multimedia development.

JavaFX Overview

JavaFX is an open-source framework for developing rich client applications using Java.
It incorporates modern GUI technologies to enable developers to create sophisticated applications.
JavaFX was initially developed as F3 by Chris Oliver at SeeBeyond, offering declarative syntax, static typing, and more.
Sun Microsystems acquired SeeBeyond and renamed F3 to JavaFX in 2007.

JavaFX History and Development

Released in 2007 as a competitor to Adobe Flash and Microsoft Silverlight.
Oracle acquired Sun Microsystems in 2010 and open-sourced JavaFX in 2013.
The first version (JavaFX 1.0) was released in Q4 2008.
Prior to version 2.0, JavaFX applications were written in JavaFX Script, which compiled to Java bytecode.

JavaFX Evolution

Starting with version 2.0 (2011), JavaFX was reimplemented as Java libraries directly usable in Java applications.
From Java 8, Java SE and JavaFX share version numbers.
Offers upgrade paths for enhancing existing GUIs, allowing Swing components in JavaFX apps and vice versa.

JavaFX Architecture

The JavaFX platform is built upon a layered architecture, including:
- JavaFX Public APIs: Provides a complete set of Java APIs for rich client application development.
- JavaFX Engine: Responsible for running JavaFX application code, composed of various components to utilize native libraries and hardware.
- JavaFX Scene Graph: A hierarchical tree of nodes representing all visual elements of the application's user interface, handling input and rendering.
- JavaFX Graphics System: Implemented beneath the scene graph, supporting both 2D and 3D graphics.
- Glass Windowing Toolkit: The lowest layer, providing native operating system services for managing windows, timers, and surfaces.
- Media Engine: Supports visual and audio media, providing components for managing media files, playback, and display.
- Web Engine: Based on WebKit, enabling web browsing functionality within JavaFX applications.

JavaFX Application Components

Stage: The window displaying the JavaFX application's GUI.
Scene: Defines the GUI as a scene graph, containing visual elements like controls, shapes, images, and more.
Nodes: Represent visual elements in the scene graph, each with attributes like transforms, opacity, effects, and event handlers.
Layout Containers: Organize child nodes within the scene, managing their arrangement (e.g., Hbox, VBox, GridPane).
Event Handler and Controller Class: Respond to user interactions with controls, defining actions for events like button clicks or text input.
