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.
