Overview Figure 10.1: Example of a Swing application SWT is an open source toolkit and is a full topic in of itself, see SWT's Homepage for more information. SWT is a third toolkit you may hear about. It is built on top of and designed as a replacement for AWT, the other UI toolkit built into Java. Swing is a tool kit in Java which provides a way to build cross platform user interfaces. Java i18n (there are 18 letter's between 'i' and 'n' in Internationalization) helps programmers develop applications in various different languages, so that you can target a global audience. Hence, when a programmer writes an application he/she must consider how to release it in as many languages as possible. Many people don't know any other language than their native tongue. Internationalization Įnglish is not the only language on this planet. It can even generate output for printers. The Java 2D API provides a rich set of graphics classes and utilities for drawing 2D graphics. Java Foundation Classes Accessibility API enables you to create programs that are accessible to disabled people by providing them with screen readers, braille displays, etc., so that they can get information from the User Interface. There is a good chance that a disabled person might not be able to use your program/application, so your program must be accessible to him or her. There are also many third-party Look and Feels available. Some examples of L&Fs are: Nimbus (really new), Metal, Aqua(Macs only), Windows Aero & Windows Classic (Windows only), and Motif(Highly customizable by the User of the Application). Each Java Swing Application has an entirely separate L&F from the rest of the applications on the computer, including other Java Applications. The Look and Feel module defines how all of the components in the application look. Many components have built-in features such as print, drag & drop, sort, open file, save file, etc. Some examples of Swing GUI components are lists, combo-boxes, labels, text areas, editor panes, buttons, menus, etc. Java Swing Components are components for the Graphical User Interfaces of Applications. Swing is a part of Java Foundation classes (JFC). Initially it was only a Java IDE, but now it supports many languages like C, C++, Python, and PHP, to name a few. Because of Java's portability, it can run on any platform, as long as Java is installed. NetBeans is a Integrated Development Environment (IDE) written completely using Java. There are many applications written in Java, and a new one pops up every day. Java Swing is a library/toolkit released by Oracle as a part of Java language which enables Java programmers to create GUIs and rich client applications. 3.1 AWT Native Interface example walk-through.1.2.2 Pluggable Look-and-Feel (PLAF) Support.
