Update on future direction of GWT-Ext

Sanjiv

In light of ExtJS going GPL, I'd like to provide an update to GWT-Ext users on the future direction of the project. While many users would like to see GWT-Ext continue to provide an LGPL stack with Ext 2.0.2, a few others felt that GWT-Ext should just go ahead and support the GPL versions of ExtJS.

Ext, what now

Unless you were stuck in a cave this past week, you know about the emergence of Ext GWT and the entire Ext JS GPL licensing debate. We had GWT-Ext’s Sanjiv Jivan weigh in, followed by Ext JS creator Jack Slocum’s heated response. While the whole soap opera is somewhat fascinating, I’m more interested in how these new developments will affect the GWT community’s two most popular widget libraries.

Jack is very verbose, but what about Darrell ? Can he explain us why he kills the MyGWT web site. I think that it will not help us to trust the future of EXT GWT. It will be wise to restore it.

Ext GWT, GWT-Ext. What now?

Successful GWT-Ext Project

Last Friday, I completed the release candidate of a commercial RIA product using GWT-Ext 2 and a JSON backend. GWT and Ext are two libraries that I kept reading about in blogs, but initially resisted using. I didn’t think GWT puts enough emphasis on aesthetic appearance out of the box, and I was not thrilled about the Ext license switch from Apache to LGPL.

I just put up a new GWT demo inspired by Jonathan Coulton’s appearance on the TWiT 133 podcast last week. I was going to write something up on how to use the gwt-voices library, but it is actually so simple to use, that there is really nothing new for me to explain. The only thing that was missing which I wanted to add, was a way to pause the songs. Currently the only options right now are play and stop.

The widgets I used are from the GWT-Ext widget library. Sanjiv has really done a nice job with the new 2.0 release.

GWT-Ext 2.0 Released: An Interview with Sanjiv Jivan

dgirard — Tue, 04 Mar 2008 14:45:00 +0100

infoq.com :

On February 6th GWT-Ext 2.0 was released. GWT-Ext is a widget library for the Google Web Toolkit (GWT) that provides a number of controls such as: trees with drag and drop, page-able/sortable grids, validating forms, and tab panels. The controls available in GWT-Ext come from the ExtJS Javascript widget library. The 2.0 release of GWT-Ext ties together GWT 1.4 and the recently released ExtJS 2.0. (For more information on ExtJS 2.0, see the InfoQ interview with ExtJS creator Jack Slocum).

GWT Ext 2.0, on the road for success

dgirard — Sat, 16 Feb 2008 10:40:00 +0100

GWT Ext 2.0 was the buzz of this week. And because in opensource, the success is always correlated with visibility, I think that with this new version, GWT Ext is on the road for success.

Sanjiv Jivan

I am pleased to announce that GWT-Ext 2.0 has finally arrived. This release of GWT-Ext is a new and significantly improved major release that is based on Ext 2.0.

Demo : http://www.gwt-ext.com/demo

Project Site : http://www.gwt-ext.com/

Download: http://code.google.com/p/gwt-ext/downloads/list

Overview of changes

Performance
The overall perfomance and responsiveness has been significantly improved in this release. All components / widgets support lazy rendering which means that they can be instantiated and managed without any overhead and their rendering is deferred to the point at which they are required to be attached to the DOM.

Unified Component model
All widgets now follow a consistent hierarchy and are subclasses of a base Component class which manages the creation, rendering and destruction lifecycle operations. Methods common to all Components are now easily accessible in a consistent, intuitive and easy to use manner. Containers, which also extends the Component class, can contain other child components which can be one of the many available widgets or another child Container. Containers only know about the child Components that are added to them, and their layout responsibilities are delegated to the assigned LayoutManager. The Panel class is a subclass of Container and is typically the class users will work with. The Panel class adds a lot of useful features like header, top toolbar, bottom toolbar, and ability to collapse and expand.

Improved Layout management
Building complex layouts in earlier versions was a little cumbersome but it is now a thing of the past. This version has an architecture that separates the responsibility of Containers, which are only aware of child Components, and the layout of the Components within the Container which is handled by an assigned LayoutManager. There are several powerful yet easy to use layouts available like BorderLayout, AccordionLayout, VerticalLayout, HorizontalLayout, AnchorLayout, TableLayout and others that make building complex layouts quite trivial. The Showcase demo has examples of variouos layouts in action.

Bean friendly API's and better support for extension
Separate config classes associated with a widget are no longer required. All Components support a default / no-op constructor and getters and setter for various properties. Various Components do have additional relevant convenience constructors that are frequently used during development like assigning a label and an action listener to a Button. In this version users can now extend any Component, add members and methods and it will be passed by reference when accessed through a callback or a lookup. In short, things work as expected in a typical Java environment.

Features

Many features of the library are illustrated in the Showcase demo. The Showcase demo is bundled with the distribution and can also be accessed online from the project page.

Grid
The performance has been significantly improved in this release and the Grid component can render a large number of rows very fast. The GridPanel now supports Single Level Row Grouping, Grouping of Summary Rows, List box look, drag and drop capabilities, checkbox and row numbered column, context menus and a lot more features. Support for Grid to Tree drag and drop has also been added.

Tree
The TreePanel component supports Checkbox nodes, Drag n Drop between trees and from a grid to a tree, sorting, filtering multi select and many other features. It also handles display of large number of nodes efficiently.

Forms
Forms have been improved significantly allowing users ultimate flexibility in adding and arranging Fields and other Components. For example multiple fields on a single row, fields displayed across tabs, Grids or even Images in a form and other configurations that were previously not easy to setup.

TabPanels
TabPanel's now support scrollable tabs (like Firefox) and context menu's. They support deferred tab rendering so that a tab's content is rendered only when the user selects the tab. Adding IFrames to tabs is also supported.

DataView
DataView is a powerful class that allows you to specify a template for rendering an given Record. You can then bind the DataView to a Store and it will render the Records using the specified HTML template. It not only renders the content but is also backed by a rich event model which allows you to have full control over user actions like click, context menu, double click etc. The main page of the Showcase demo uses a DataView to display the thumbnail images of the samples.

Windows
A Window is a specialized Panel that supports floating, dragging, minimize/maximize/restore. Any other Container or Component can be added to a Window as illustrated by various examples in the Showcase demo.

New Widgets

Accordion
An Accordion is simply a Container that is assigned an AccordionLayout. All child Panel's added to it will be laid out in the form of an Accordion. And since any Contaienr can be added to a Window, creating a floatable Accordion is a breeze.

ProgressBar
Highly configurable ProgressBar and support for custom styling.

Tooltips
Powerful and easy to use Tooltips that can be applied to any Component. Also supports loading remote tooltip content using Ajax.

CycleButton
This is a specialized Menu Button that contains a menu of CheckItem's. The button automatically cycles through each menu item when clicked.

TimeField
A field that has a dropdown with a time picker.

Hidden Field
Ability to add a hidden input field to a Form.

Several other goodies

GWT-Plus is fully compatible with GWT-Ext 2.0.

Sanjiv,thanks for your great job !

Update : False alarm, thanks Chris

Ed Burnette

Instantiations demonstrated their new GWT Designer at a BOF last night at Eclipse World. According to Eric Clayberg, Sr. VP of Product Development, the response was very enthusiastic.

I hope that GWT Designer will support GWT-Ext, MyGWT and others.
And remember : "Instantiations is giving back to the community by donating its products to committers who are working on non-commercial open source projects."
