Is Java SWT still used?

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.

What is the difference between SWT and Swing?

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.

Is Swing still used in Java 2020?

Absolutely yes. Legacy swing applications are still supported and enhanced.

Is Swing good for GUI?

Swing provides a rich set of widgets and packages to make sophisticated GUI components for Java applications. Swing is a part of Java Foundation Classes(JFC), which is an API for Java GUI programing that provide GUI.


Pros Swing:

  • part of java library, no need for additional native libraries
  • works the same way on all platforms
  • Integrated GUI Editor in Netbeans and Eclipse
  • good online tutorials by Sun/Oracle
  • Supported by official java extensions (like java OpenGL)

Cons Swing:

  • Native look and feel may behave different from the real native system.
  • heavy components (native/awt) hide swing components, not a problem most of the time as as use of heavy components is rather rare

Pros SWT:

  • uses native elements when possible, so always native behavior
  • supported by eclipse, gui editor VEP (VEP also supports Swing and AWT)
  • large number of examples online
  • has an integrated awt/swt bridge to allow use of awt and swing components

Cons SWT:

  • requires native libraries for each supported system
  • may not support every behavior on all systems because of native resources used (hint options)
  • managing native resources, while native components will often be disposed with their parent other resources such as Fonts have to be manually released or registered as dispose listener to a component for automatic release.

An important thing to consider is that some users and some resellers (Dell) install a 64 bit VM on their 64 bit Windows, and you can't use the same SWT library on 32 bit and 64 bit VMs.

This means you will need to distribute and test different packages depending on whether users have 32-bit or a 64-bit Java VM. See this problem with Azureus, for instance, but you also have it with Eclipse, where as of today the builds on the front download page do not run on a 64 bit VM.


pro swing:

  • The biggest advantage of swing IMHO is that you do not need to ship the libraries with you application (which avoids dozen of MB(!)).
  • Native look and feel is much better for swing than in the early years
  • performance is comparable to swt (swing is not slow!)
  • NetBeans offers Matisse as a comfortable component builder.
  • The integration of Swing components within JavaFX is easier.

But at the bottom line I wouldn't suggest to use 'pure' swing or swt ;-) There are several application frameworks for swing/swt out. Look here. The biggest players are netbeans (swing) and eclipse (swt). Another nice framework could be griffon and a nice 'set of components' is pivot (swing). Griffon is very interesting because it integrates a lot of libraries and not only swing; also pivot, swt, etc


I would use Swing for a couple of reasons.

  • It has been around longer and has had more development effort applied to it. Hence it is likely more feature complete and (maybe) has fewer bugs.

  • There is lots of documentation and other guidance on producing performant applications.

  • It seems like changes to Swing propagate to all platforms simultaneously while changes to SWT seem to appear on Windows first, then Linux.

If you want to build a very feature-rich application, you might want to check out the NetBeans RCP (Rich Client Platform). There's a learning curve, but you can put together nice applications quickly with a little practice. I don't have enough experience with the Eclipse platform to make a valid judgment.

If you don't want to use the entire RCP, NetBeans also has many useful components that can be pulled out and used independently.

One other word of advice, look into different layout managers. They tripped me up for a long time when I was learning. Some of the best aren't even in the standard library. The MigLayout (for both Swing and SWT) and JGoodies Forms tools are two of the best in my opinion.


I whould choose swing just because it's "native" for java.
