Study Notes

Heavyweight vs. Lightweight Components

Heavyweight AWT components rely on the underlying native system for rendering, causing potential issues with look and feel consistency across platforms.
Lightweight Swing components are drawn entirely in Java, allowing for a consistent appearance and enabling more flexibility in design.

Java Foundation Classes (JFC)

The primary purpose of JFC is to provide a rich set of tools for building graphical user interfaces (GUIs) in Java applications.
JFC includes features such as accessibility support and a pluggable look-and-feel architecture.

Components of JFC

Components included in JFC are Swing, Java 2D, and accessibility support.
The Java AWT (Abstract Window Toolkit) is NOT a part of JFC.

Pluggable Look and Feel (PL&F)

PL&F in Swing allows developers to change the appearance of the user interface dynamically without altering the underlying application code, fostering customization.

Java 2D Purpose

Java 2D is a part of JFC that provides advanced graphics capabilities for rendering two-dimensional shapes, images, and text, enhancing the visual aspects of GUIs.

Truths about Swing Components

Swing components are lightweight and can be customized, allowing them to support both complex layouts and various user interactions.

Platform Independence of GUI Frameworks

Swing is considered platform-independent, as it does not rely on native GUI systems, ensuring that Java applications look the same on any operating system.

Advantages of Swing over AWT

Swing components offer a richer set of UI controls, better performance, and a more flexible event model compared to AWT components.

Customizability of Swing

Swing controls can be easily customized and extended, unlike AWT components which are more rigid and closely tied to native systems.

Swing Design Pattern

Swing primarily follows the Model-View-Controller (MVC) design pattern, separating data, user interface, and event handling.

Importing Swing Components

The javax.swing package contains the classes and interfaces necessary for using Swing components in Java applications.

Custom Implementation Feature of Swing

Swing's support for custom rendering and user interface elements allows integration of different implementations and frameworks, enhancing the versatility of GUI development.

Root of Visual Component Class Hierarchy

The root of the visual component class hierarchy in JFC is the JComponent class, forming the base for all Swing components.

Component Set in GUI Frameworks

Swing provides a powerful set of GUI components, including tables, lists, scroll panes, and color choosers, which are not available in AWT.

Uniform Changes in Swing

Swing's architecture allows for global changes to the user interface theme without the need for extensive modifications to the application code.
