The debate continues w.r.t. SWT and Swing - in response to comments made by James Gosling on SWT in Australia, Bruce Eckel has enlisted the help of Chris Grindstaff, a contributor to the SWT chapter in Bruce's latest edition of "Thinking in Java".
In Gosling on SWT, Chris counters that AWT is not SWT: "The big difference between the two is AWT is very much least-common-denominator across all platforms. SWT isn't. The other significant difference is AWT chose to hide the emulation layer in C. In other words, java.awt.Button is the same on all platforms, while the native peer differs on each platform. One of the consequences of this is porting is harder, some things are in Java, some aren't. [...] In SWT the org.eclipse.swt.Button Java/class is different on each platform. The SWT lib does nothing but stuff methods straight to the OS. One toolset and less duplication."
