Google Web Toolkit (GWT) is an open source Java development framework for building Ajax-enabled web applications. Instead of the hodgepodge of technologies that developers typically use for Ajax–JavaScript, HTML, CSS, and XMLHttpRequest–GWT lets developers implement rich client applications with pure Java, using familiar idioms from the AWT, Swing, and SWT. GWT goes beyond most Ajax frameworks by making it easy to build desktop-like applications that run in the ubiquitous browser, where the richness of the user interface is limited only by the developer’s imagination.

This book focuses on the more advanced aspects of GWT that you need to implement real-world applications with rich user interfaces but without the heavy lifting of JavaScript and other Ajax-related technologies. Each solution in this practical, hands-on book is more than a recipe. The sample programs are carefully explained in detail to help you quickly master advanced GWT techniques, such as implementing drag-and-drop, integrating JavaScript libraries, and using advanced event handling methodologies.

Solutions covered include

•   Building custom GWT widgets, including both high-level composites and low-level components

•   Implementing a viewport class that includes iPhone-style automated scrolling

•   Integrating web services with GWT applications

•   Incorporating the Script.aculo.us JavaScript framework into GWT applications

•   Combining Hibernate and GWT to implement database-backed web applications

•   Extending the GWT PopupPanel class to implement a draggable and resizable window

•   Creating a drag-and-drop module, complete with drag sources and drop targets

•   Deploying GWT applications to an external server

•   Dynamically resizing flex tables

•   Using GWT widgets in legacy applications developed with other frameworks, such as Struts and JavaServer Faces

Praise for Design Patterns in Ruby

" Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly encounter. Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth of experience available to Ruby developers for their own daily work."

—Steve Metsker, Managing Consultant with Dominion Digital, Inc.

"This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting to overly technical explanations. Written in a precise, yet almost informal style, this book covers enough ground that even those without prior exposure to design patterns will soon feel confident applying them using Ruby. Olsen has done a great job to make a book about a classically 'dry' subject into such an engaging and even occasionally humorous read."

—Peter Cooper

"This book renewed my interest in understanding patterns after a decade of good intentions. Russ picked the most useful patterns for Ruby and introduced them in a straightforward and logical manner, going beyond the GoF's patterns. This book has improved my use of Ruby, and encouraged me to blow off the dust covering the GoF book."

—Mike Stok

" Design Patterns in Ruby is a great way for programmers from statically typed objectoriented languages to learn how design patterns appear in a more dynamic, flexible language like Ruby."

—Rob Sanheim, Ruby Ninja, Relevance

Most design pattern books are based on C++ and Java. But Ruby is different—and the language's unique qualities make design patterns easier to implement and use. In this book, Russ Olsen demonstrates how to combine Ruby's power and elegance with patterns, and write more sophisticated, effective software with far fewer lines of code.

After reviewing the history, concepts, and goals of design patterns, Olsen offers a quick tour of the Ruby language—enough to allow any experienced software developer to immediately utilize patterns with Ruby. The book especially calls attention to Ruby features that simplify the use of patterns, including dynamic typing, code closures, and "mixins" for easier code reuse.

Fourteen of the classic "Gang of Four" patterns are considered from the Ruby point of view, explaining what problems each pattern solves, discussing whether traditional implementations make sense in the Ruby environment, and introducing Ruby-specific improvements. You'll discover opportunities to implement patterns in just one or two lines of code, instead of the endlessly repeated boilerplate that conventional languages often require.

Design Patterns in Ruby also identifies innovative new patterns that have emerged from the Ruby community. These include ways to create custom objects with metaprogramming, as well as the ambitious Rails-based "Convention Over Configuration" pattern, designed to help integrate entire applications and frameworks.

Engaging, practical, and accessible, Design Patterns in Ruby will help you build better software while making your Ruby programming experience more rewarding.
