This book describes the history of Java GUI toolkits, explains why SWT (Standard Wizard Tool kit) is superior, and then provides extensive examples of building applications with SWT. This book takes developers through the entire class hierarchy of SWT, explaining clearly (with Java code) how to use all the widgets in the toolkit. JFace, an additional abstraction layer built on SWT, is also described and this book demonstrates how to build applications with JFace with explanation and example code.
