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.
