Editing Swing (Java) (section)

===Relationship to SWT===
The [[Standard Widget Toolkit]] (SWT) is a competing toolkit originally developed by [[IBM]] and now maintained by the [[Eclipse (software)|Eclipse]] [[Free software community|community]]. SWT's implementation has more in common with the heavyweight components of AWT. This confers benefits such as more accurate fidelity with the underlying native windowing toolkit, at the cost of an increased exposure to the native platform in the programming model.

There has been significant debate and speculation about the performance of SWT versus Swing; some hinted that SWT's heavy dependence on [[Java Native Interface|JNI]] would make it slower when the GUI component and Java need to communicate data, but faster at rendering when the data model has been loaded into the GUI, but this has not been confirmed either way.<ref>{{cite web |last1=Strenn |first1=Stephen |date=2006-03-03 |df=mdy |url=http://www.javalobby.org/java/forums/t65168.html |title=Swing vs. SWT Performance - Have a Look at the Call Stacks |work=Javalobby |url-status=usurped |archive-url=https://web.archive.org/web/20170917172003/http://www.javalobby.org/java/forums/t65168.html |archive-date=2017-09-17}}</ref> A fairly thorough set of benchmarks in 2005 concluded that neither Swing nor SWT clearly outperformed the other in the general case.<ref>{{cite web

 |quote=''It is hard to give a rule-of-thumb where SWT would outperform Swing, or vice versa. In some environments (e.g., Windows), SWT is a winner. In others (Linux, [[VMware]] hosting Windows), Swing and its redraw optimization outperform SWT significantly. Differences in performance are significant: factors of 2 and more are common, in either direction.''
