Features Of Swing Class
- Pluggable look and feel.
- Uses MVC architecture.
- Lightweight Components
- Platform Independent
- Advanced features such as JTable, JTabbedPane, JScollPane, etc.
- Java is a platform-independent language and runs on any client machine, the GUI look and feel, owned and delivered by a platform-specific O/S, simply does not affect an application’s GUI constructed using Swing components.
- Lightweight Components: Starting with the JDK 1.1, its AWT-supported lightweight component development. For a component to qualify as lightweight, it must not depend on any non-Java [O/s based) system classes. Swing components have their own view supported by Java’s look and feel classes.
- Pluggable Look and Feel: This feature enable the user to switch the look and feel of Swing components without restarting an application. The Swing library supports components’ look and feels that remain the same across all platforms wherever the program runs. The Swing library provides an API that gives real flexibility in determining the look and feel of the GUI of an application
- Highly customizable – Swing controls can be customized in a very easy way as visual appearance is independent of internal representation.
- Rich controls– Swing provides a rich set of advanced controls like Tree TabbedPane, slider, colorpicker, and table controls.
Introduction to Java Swing
Swing is a Java Foundation Classes [JFC] library and an extension of the Abstract Window Toolkit [AWT]. Java Swing offers much-improved functionality over AWT, new components, expanded components features, and excellent event handling with drag-and-drop support.
Introduction of Java Swing
Swing has about four times the number of User Interface [UI] components as AWT and is part of the standard Java distribution. By today’s application GUI requirements, AWT is a limited implementation, not quite capable of providing the components required for developing complex GUIs required in modern commercial applications. The AWT component set has quite a few bugs and does take up a lot of system resources when compared to equivalent Swing resources. Netscape introduced its Internet Foundation Classes [IFC] library for use with Java. Its Classes became very popular with programmers creating GUI’s for commercial applications.
- Swing is a Set of API (API- Set of Classes and Interfaces)
- Swing is Provided to Design Graphical User Interfaces
- Swing is an Extension library to the AWT (Abstract Window Toolkit) 5:00 – 5:30 pm
- Includes New and improved Components that have been enhancing the looks and Functionality of GUIs’
- Swing can be used to build (Develop) The Standalone swing GUI Apps as Servlets and Applets
- It Employs model/view design architecture.
- Swing is more portable and more flexible than AWT, the Swing is built on top of the AWT.
- Swing is Entirely written in Java.
- Java Swing Components are Platform-independent, and The Swing Components are lightweight.
- Swing Supports a Pluggable look and feel and Swing provides more powerful components.
- such as tables, lists, Scrollpanes, Colourchooser, tabbed pane, etc.
- Further Swing Follows MVC.
