Standard Widget Toolkit

Standard Widget Toolkit (SWT) adalah sebuah alat kerja (toolkit) yang berisikan widget untuk membuat graphical user interface (GUI) di dalam bahasa pemrograman Java. SWT merupakan alternatif GUI library di samping Abstract Windowing Toolkit (AWT) dan Swing.

SWT dikembangkan oleh Eclipse Foundation sebagai GUI untuk Eclipse IDE (Integrated Development Environment)

SWT is written in Java. To display GUI elements, the SWT implementation accesses the native GUI libraries of the operating system using JNI (Java Native Interface) in a manner that is similar to those programs written using operating system-specific APIs. Programs that call SWT are portable, but the implementation of the toolkit, despite the fact that it is written in Java, is unique for each platform.

SWT is developed by the Eclipse Foundation, and is developed in tandem with the Eclipse IDE. The toolkit is licensed under the Eclipse Public License, (an Open Source Initiative approved open source license).[1]
