Google Web Toolkit

Web Design & Development Guide

Google Web Toolkit

Home | Up

The Google Web Toolkit is an open source toolkit allowing developers to create Ajax applications in the Java programming language [1]. GWT supports rapid client/server development and debugging in any Java IDE. In a subsequent deployment step, the GWT compiler translates a working Java application into equivalent JavaScript that programmatically manipulates a web browser's HTML DOM using DHTML techniques. GWT emphasizes reusable, efficient solutions to recurring Ajax challenges, namely asynchronous remote procedure calls, history management, bookmarking, and cross-browser portability.


  • Dynamic, reusable UI components
  • Simple RPC
  • Browser history management
  • Debugging using java debuggers
  • Browser compatible
  • JUnit integration
  • Internationalization
  • Interoperability and fine-grained control
  • Google API Library: Google Gears support
  • Completely Open Source

Available widgets

As of December 2006, the Google Web Toolkit contains widgets for:

  • Panels (AbsolutePanel, CellPanel, DeckPanel, DockPanel, and many more)
  • Buttons
  • Checkboxes
  • Radio Buttons
  • Tables (FlexTable, Grid, etc.)
  • Dialog Boxes
  • HTML primitives (Images, Hyperlinks, and raw HTML)
  • Menus and Menubars
  • Scrollpanes
  • Tabs
  • Trees

Many common widgets not found in the Google Web Toolkit have been implemented in third-party libraries, such as the GWT Component Library.

The rocket-gwt contains many extras which help developers author sophisticated GWT powered applications including:

  • templated based code generation using deferred binding
  • bean factories with aop support (on the client)
  • cometting of objects
  • json serialization
  • browser independent css manipulation
  • programmatic support for determining and changing (mouse) selections.
  • many additional widgets.
