Google Web Toolkit 1.4: +Final -Beta

Category: Google, GWT

<p>When I see something at Google have its beta tag removed, I know that the team has gone through a lot to deserve that privilege. We recently noted that GWT 1.4 was almost there, and now it is. GWT 1.4 is here.

The latest release comes with a revamped Mail example that shows a three-paned email client written in GWT.

For more information read the story of GWT on the Official Google Blog, or the details on the GWT blog including the following information on enhancements:

New widgets and libraries

  • RichTextArea, HorizontalSplitPanel and VerticalSplitPanel, SuggestBox, DisclosurePanel, PushButton, ToggleButton, and an enhanced Image widget make advanced applications easier than ever.
  • ImageBundle automatically consolidates multiple images into a single HTTP request.
  • NumberFormat and DateTimeFormat make easy work of complex internationalization and localization.
  • You can finally use java.lang.Serializable with GWT RPC, and the GWT RPC server-side subsystem is no longer intimately tied to servlets. You can easily wire it into any Java back-end infrastructure. Spring fans, rejoice.
  • A new JUnit-based benchmarking subsystem makes measuring and comparing the speed of code snippets as easy as writing unit tests.

New deployment options and optimizations

  • Adding GWT modules to an HTML page is now simple: just add a <script> tag.
  • You can now include GWT modules across domains. Note that including scripts from other sites that you don’t fully trust is a big security risk.
  • External JavaScript files referenced from your GWT module load synchronously now, so script ready-functions are no longer needed.
  • Auto-generated RPC whitelist files are now produced during compilation to help catch accidentally responding with objects that compiled GWT client code wouldn’t be able to deserialize.
  • The GWT distribution now includes a DTD for the GWT module XML format, making it easier to configure modules in an DTD-aware XML editor.

So why did’t they show off the richtexteditor in the mail app. Can the splitpanels be resized?

Take a look at this example for the Rich Text Editor:
