The '''Standard Widget Toolkit''' ('''SWT''') is a graphical [[widget toolkit]] for use with the [[Java (software platform)|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)|Swing]] Java [[graphical user interface]] (GUI) toolkits provided by [[Sun Microsystems]] as part of the [[Java Platform, Standard Edition]] (J2SE).

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 interface]]s (APIs). Programs that call SWT are portable, but the implementation of the toolkit, despite part of it being written in [[Java (programming language)|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]].<ref>{{Cite web |author= Open Source Initiative |author-link= Open Source Initiative |title= Licenses By Name |url= http://www.opensource.org/licenses/ |access-date= 2007-03-24}}</ref>
