  • the title of the slide 'A Tale of Two java GUI libraries ' i inspired it from this site http://www.developer.com/java/other/article.php/2179061/Swing-and-SWT-A-Tale-of-Two-Java-GUI-Libraries.htm

    for the contents in the slide i gathered it by reading from many books and sites

Swt vs swing

  1. 1. SWING & SWTA Tale of Two Java GUI Libraries
  2. 2. AWT (ABSTRACT WINDOW TOOLKIT) Oldest toolkit , part of java standard API It includes classes like Button, TextField, and Menu It also provides the necessary event handling mechanism AWT controls may behave differently under different operating systemsFor example, it might be possible to right-click on a button under operating system A showing a context menu, but impossible to do so under operating system B
  3. 3.  It relies on the native GUI elements of each operating systems so known as“Platform dependent “Examplecreate a Button, a native Windows button will show up if the application is running under windows, a native Mac OS button will show up if the application is running under Mac OS, a native Linux button will show up if the application is running under Linux, and so on.
  4. 4.  GUI components are drawn very quickly. This is knows as "native performance“ In AWT, native code, written in a language like C or C++ GUI components look natural for the users of each operating systems. This is knows as "native look and feel“ AWT only include components that exist in ALL supported operating systems(least common denominator) so the problem came from here
  5. 5. SWINGo Part of the Java standard APIo It includes classes like JButton, JTextFiled, JMenu, and JTree Advantage  It still relies on AWT classes for event handling but for rendering components it relies on the Java2D API to draw components from scratch  Does not suffer from the "least common denominator“ because it have Swing classes defining how to draw Swing controls from scratch  "platform independence“
  6. 6.  "Pluggable look and feel" that allows controls to appear with a different look and feel if desired  Swing components follow the Model-View- Controller (MVC) paradigm, and thus can provide a much more flexible UI. Disadvantage  Rendering Swing components is slower than rendering AWT components because they are drawn from scratch  Large memory  When a change happen to the operating system so it doesn’t update automatically
  7. 7. SWT (STANDARD WIDGET TOOLKIT) It is NOT part of the Java standard API Advantage  SWT tries to combine the best of AWT and Swing  There is a native component written for each operating system called Java Native interface  Use less memory  Rich set of widgets which used to make good looking  Run faster  When a change happen to the operating system so it update automatically
  8. 8.  Disadvantage • Also you have to build separate installers for every operating systems which you are to support. • Native look and Feel support
  9. 9. SUMMARY There is a big debate between Java developers about whether Swing or SWT is better So it up to you to choose the most appropriate GUI library (SWT or Swing ) to your application
