What is the difference between Swing and AWT? - Stack Overflow

AWT is a Java interface to native system GUI code present in your OS. It will not work the same on every system, although it tries. Swing is a more-or-less pure-Java GUI. It uses AWT to create an operating system window and then paints pictures of buttons, labels, text, checkboxes, etc., into that window and responds to all of your mouse-clicks, key entries, etc., deciding for itself what to ...

Java GUI frameworks. What to choose? Swing, SWT, AWT, SwingX, JGoodies ...

AWT, Swing and SWT are UI toolkits but I would certainly not call them "frameworks". Frameworks are based upon a given UI toolkit and provide the glue to build your application. First, you should choose the UI toolkit and then choose a framework that works on that toolkit. FWIW, I would choose Swing with my own home-made Guts-GUI framework :-)

java - SWT and AWT, what is the difference? - Stack Overflow

AWT is the original cross-platform, native-peer based GUI widget set. It drew a lot of complaints for not being perfectly consistent across platforms. Sun built the Swing widget set to answer those concerns, building it with pure Java (no native peers), but people complained that it was slow and ugly. IBM built SWT as a native-peer based competitor to Swing. It succeeded because it looks good ...

java - AWT vs. Swing....why use Swing? - Stack Overflow

No, AWT is doing the painting, or more to the point, it provides access to the Graphics layer for Swing to paint on. Swing, unlike JavaFX, borrows a lot from the AWT API so it could take advantage of what was already available at the time. Things like Image, Graphics for example, come from the AWT API, but Swing brings a lot, include drag'n'drop, the transferable API, UndoManager, key bindings ...
