Java GUI frameworks. What to choose? Swing, SWT, AWT, SwingX, JGoodies . . . AWT Is the very foundation of swing, it performs well but is lacking in advanced components If you intend to create rich applications, AWT is probably not the way to go However for smaller gui applications that doesn't require rich user interfaces This might suit perfectly as it's a tried and proven framework
Do I have to learn AWT before learning Swing? - Stack Overflow There's really no point in learning AWT first Swing replaces a lot of AWT's concepts and components, but integrates many others unchanged (such as layout managers) If you learn Swing, you'll learn those parts of AWT that still matter (and how they are used in Swing) pretty much automatically Sun's Swing tutorial is a pretty good starting point
Where can I find detailed information on how AWT interacts with the . . . A java awt datatransfer package for use with the Clipboard and Drag and Drop A basic set of GUI widgets such as buttons, text boxes, and menus It also provides the AWT Native Interface, which enables rendering libraries compiled to native code to draw directly to an AWT Canvas object drawing surface
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
Diferença entre AWT e Swing na renderização de componentes Entretanto, o AWT sempre vai usar uma instância da subclasse Graphics2D, então você pode fazer o cast seguramente se precisar para ter acesso a um conjunto maior e melhor de métodos disponíveis E lembrando que no final das contas, quem controla tudo é o AWT O Swing é apenas uma camada por cima do AWT, e não um substituto completo
Exception in thread AWT-EventQueue-0 java. lang. NullPointerException . . .
