The Standard Widget Toolkit SWT is a graphical widget toolkit for use with the Java platform. It was originally developed by Stephen Northover at IBM and is now maintained by the Eclipse Foundation in tandem with the Eclipse IDE. It is an alternative to the Abstract Window Toolkit AWT and Swing Java graphical user interface GUI toolkits provided by Sun Microsystems as part of the Java Platform, Standard Edition J2. SE. To display GUI elements, the SWT implementation accesses the native GUI libraries of the operating system using Java Native Interface JNI in a manner that is similar to those programs written using operating system specific application programming interfaces APIs. Programs that call SWT are portable, but the implementation of the toolkit, despite part of it being written in Java, is unique for each platform. The toolkit is free and open source software distributed under the Eclipse Public License, which is approved by the Open Source Initiative. HistoryeditThe first Java GUI toolkit was the Abstract Window Toolkit AWT, introduced with Java Development Kit JDK 1. Sun Microsystems Java platform. The original AWT was a simple Java wrapper library around native operating system supplied widgets such as menus, windows, and buttons. Swing was the next generation GUI toolkit introduced by Sun in Java Platform, Standard Edition J2. SE 1. 2. Swing was developed to provide a richer set of GUI software components than AWT. Swing GUI elements are all Java with no native code instead of wrapping native GUI components, Swing draws its own components by using Java 2. D to call low level operating system drawing routines. The roots of SWT go back to work that Object Technology International OTI, did in the 1. Smalltalk, originally for OTI Smalltalk, which became IBM Smalltalk in 1. IBM Smalltalks Common Widget layer provided fast, native access to multiple platform widget sets while still providing a common API without suffering the lowest common denominator problem typical of other portable graphical user interface GUI toolkits. IBM was developing Visual. Age, an integrated development environment IDE written in Smalltalk. They decided to open source the project, which led to the development of Eclipse, intended to compete against other IDEs such as Microsoft Visual Studio. Eclipse is written in Java, and IBM developers, deciding that they needed a toolkit that had native look and feel and native performance, created SWT as a Swing replacement. SWT is a wrapper around native code objects, such as GTK objects, Motif objects etc. Because of this, SWT widgets are often referred toby whom as heavyweight, evoking images of a light Java wrapper around a heavy native object. In cases where native platform GUI libraries do not support the functionality required for SWT, SWT implements its own GUI code in Java, similar to Swing. In essence, SWT is a compromise between the low level performance and look and feel of AWT and the high level ease of use of Swing. According to the Eclipse Foundation, SWT and Swing are different tools that were built with different goals in mind. The purpose of SWT is to provide a common API for accessing native widgets across a spectrum of platforms. The primary design goals are high performance, native look and feel, and deep platform integration. Swing, on the other hand, is designed to allow for a highly customizable look and feel that is common across all platforms. It has been arguedby whom that SWT features a clean design, in part inspired by Erich Gamma of Design Patterns fame. SWT is a simpler toolkit than Swing, with less possibly extraneous functionality for the average developer. This has led some peoplewho to argue that SWT lacks functionality when compared to Swing. James Gosling, the creator of the Java language, has argued that SWT is too simple, and is a difficult toolkit to port to new platforms for the same reason that AWT once had porting problems that it is too simple, too low level, and too tied to the Win. GUI API, leading to problems adapting the SWT API to other GUI toolkits, such as Motif and OS X Carbon. Although SWT does not implement the popular modelviewcontroller MVC architecture used in Swing and many other high level GUI toolkits, the JFace library, which is developed as part of the same Eclipse project, does provide a cross platform, higher level MVC abstraction atop SWT. Developers may choose to use JFace to provide more flexible and abstract data models for complex SWT controls such as trees, tables, and lists, or access those controls directly as needed. Look and feeleditSWT widgets have the same look and feel as native widgets because they often are the same native widgets. This is in contrast to the Swing toolkit where all widgets are emulations of native widgets. In some cases the difference is distinguishable. For example, the mac. OS tree widget features a subtle animation when a tree is expanded and default buttons actually have an animated pulsing glow to focus the users attention on them. The default Swing version of these widgets do not animate. Since SWT is simply a wrapper around native GUI code, it does not require large numbers of updates when that native code is changed, providing that operating system vendors are careful not to break clients of their API when the operating systems are updated. The same cannot be said of Swing, which supports the ability to change the look and feel of the running application with pluggable looks and feels. These enable emulating the native platform user interface using themes, which must be updated to mirror operating system GUI changes, such as theme or other look and feel updates. SWT aims for deep platform integration, the Eclipse reference to SWTs use of native widgets. According to Mauro Marinillia of developer. SWT can be a plus. This deep integration can be useful in a number of ways, for example enabling SWT to wrap Active. X objects on Microsoft Windows. Programmingedit. A simple GUI application using SWT running in a GTK environment. The following is a basic Hello World program using SWT. It shows a window Shell and a label. Hello. WorldpublicstaticvoidmainStringargsDisplaydisplaynew. Display Shellshellnew. Shelldisplay Labellabelnew. Labelshell,SWT. NONE label. TextHello World label. Disposedif display. And. Dispatchdisplay. Contrary to Swing, a Display class is necessary to access the underlying operating system, and its resources must be explicitly disposed of when they are no longer used. Platform supporteditSWT must be ported to every new GUI library that needs supporting. Unlike Swing and AWT, SWT is not available on every Java supported platform since SWT is not part of the Java release. There is also some evidence that the performance of SWT on platforms other than Windows is noticeably less efficient. Since SWT uses a different native library for each platform, SWT programs may be exposed to platform specific bugs. SWT exposes programs to more low level details than Swing. This is because SWT is technically just a layer over native library provided GUI functionality, exposing the programmer to native GUI code is part of the design intent of SWT Its goal is not to provide a rich user interface design framework but rather the thinnest possible user interface API that can be implemented uniformly on the largest possible set of platforms while still providing sufficient functionality to build rich graphical user interface GUI applications. Since the SWT implementation is different for each platform, a platform specific SWT library JAR file must be distributed with each application. As of March 2. 01. SWT supports these platforms andor GUI libraries As of 1 March 2.
