What is the .SWT File Extension?

.SWT File Extension Description:

SWT stands for Standard Widget Toolkit that produces widget toolkit graphics which are very useful to the Java platform. It was originally developed by IBM but is now being maintained by Eclipse Foundation in partnership with the Eclipse IDE. Written in Java, files with the .swt file extension were developed as an alternative to Abstract Window Toolkit (AWT) and Swing Java GUI toolkits developed by Sun Microsystems. The widget toolkit graphics are saved in files with the .swt file extension.

AWT was the first Java GUI toolkit which started as just a simple wrapper around local widgets such as menus, windows and buttons. Sun Microsystems later developed Swing Java GUI which provided a better set of GUI components than AWT. About the same period, IBM was developing Visual Age Integrated Development Environment (IDE) which later led to the birth of Eclipse IDE. Since Eclipse is written in Java, IBM people decided to create a new toolkit that has a "native look and feel" and a "native performance," thus, the SWT file extension which became an alternative for AWT Java GUI and Swing Java GUI.

The purpose of the SWT file extension is to provide a common API for accessing native widgets across the spectrum of platforms. The primary design goals are high performance, native look and feel, and deep platform integration.

Files with the .swt file extension serve as a wrapper enclosing local code objects, like GTK+ objects, Motif objects, etc. For this reason, these files are frequently described as "heavyweights" suggesting impressions of light Java wrapper enclosing a "heavy" local object.

When it happen that local platform Java GUI libraries do not support the application required by the files with the .swt file extension, SWT executes its own Java GUI code which is akin to Swing Java GUI. So, essentially the file with the .swt file extension is somewhat an effective middle bridge between the low level operation, look, and feel of AWT Java GUI and the high level practical and simple use of Swing Java GUI.

The SWT file extension has been available for C++ (called SWT C++) since January 2008. The NewJ Desktop made this possible without the use of JNI. Currently, SWT C++ is only maintained for Microsoft Windows and Microsoft Visual C++ 7.1 (Visual Studio 2003).
