Study Notes

Java Frameworks for GUI

Java Swing is a graphical framework for building portable Java-based graphical user interfaces.
The set of application program interfaces (APIs) used by Java programmers to create graphical user interface (GUI) objects is Java Abstract Window Toolkit (AWT).

Swing Framework

Swing is used to create window-based applications.
Swing components allow applications to run with native look and feel on different platforms due to their feature of Pluggable Look and Feel.
Swing components contain replacements for AWT components.

Component Characteristics

Lightweight components are distinct from heavyweight components in that they are responsible for rendering their own pixels and shape.
The main advantage of Swing components is their ability to provide a good look and feel to the application.
Swing components provide a good look and feel to the application due to their ability to customize their appearance.

Component Hierarchy

The JComponent class is the base class in the Swing component hierarchy.
Swing's loosely coupled architecture allows for easy modification and extension of components.
Swing components are considered manageable due to their ability to be easily modified and extended.

Comparison with AWT

Swing components are distinct from AWT components in that they are lightweight, whereas AWT components are heavyweight.
Swing's component hierarchy is more flexible and customizable than AWT's.

Additional Features

Swing provides support for user interface framework mappings through its feature of UIFramework.
Swing supports customizability for its controls through its ability to customize their appearance and behavior.
Swing is associated with the "MVC" (Model-View-Controller) architecture.
