Ext GWT 2.0 Milestone 2 Released
May 20, 2009 by Darrell Meyer
The Ext Team is happy to announce the availability of Ext GWT 2.0 Milestone 2 available for immediate download. Ext GWT 2.0 M2 is packed full of new components and features, expanding on the Ext GWT 1.0 feature set. Included in this release, are several performance improvements which noticeably improve initial render and layout execution times. Most notably, Ext GWT has closed the feature gap that once existed between its sister project Ext JS. Developers looking to use Ext GWT can now rest easy knowing that they are not missing out on any cool features.
GWT 1.6
Ext GWT 2.0 works with GWT 1.6. With GWT 1.6, the application deployment design was changed to make it easier to integrate your GWT application into an existing J2EE application. Ext GWT 2.0 has been updated to take advantage of the new GWT design.
Ext GWT 2.0 introduces several new UI Components and enhancements to many existing components. Here is a partial listing of some of the new and enhanced components:
New UI Components
- Charting
- HtmlEditor (with ColorPalette)
- RowEditor
- Widget Renderer Grid
- ButtonGroup
- Status
- HBoxLayout & VBoxLayout
Live Charting
The chart package will allow you to visualize your data with flash based charting. Each chart binds directly to a ListStore. The new FlashComponent class, which extends BoxComponent, allows you to easily create custom Flash Components. By binding the charts directly to a ListStore, you don’t have to worry about updating your chart, they will update automatically. Included is a full Java object model for configuring and constructing the charts, no need to mess with JSON or XML.
HTML Editor – Rich Text Editor
The often requested components is now available. HtmlEditor is a lightweight WYSIWYG editor that integrates well with the other Ext components. The HtmlEditor component is easy to customize with other features you may need.
RowEditor
Editing a row in a grid just got a lot easier. The RowEditor is another great new UI component allowing you to rapidly edit full rows in a grid. You can even enable a validation mode which uses the new AnchorTips to notify the user of all validation errors at once.
Widget Renderer
It is now possible to add widgets to cells in Grid. To use widgets, simply use a GridCellRenderer and return a widget, rather than a HTML fragment.
ButtonGroup
ButtonGroup is a new component that will allow you to group together Buttons of different sizes to create complex toolbars enabling your users to find the most common actions first.
Status
The new Status component can be used with a ToolBar to replicate the status area of an application.
HBoxLayout & VBoxLayout
Two new and extremely flexible layouts for layout out children in a single row or column. Box layouts allow precise control of the size and position of the children in a container.
Enhanced Components
- Buttons
- Toolbar Overflow
- Menu Overflow
- AnchorTips
- Buffered GridView
Buttons
Buttons in Ext GWT 2.0 have been refactored to be a valid BoxComponent which enables them to partake in layout management. Buttons can now scale to any height or width and have advanced text positioning.
Toolbar Overflow
Toolbars can now create a menu for items that don’t fit the visible toolbar area. The items in the menu still react with the same handlers as the toolbar items. This new behavior is turned on by default and can be disabled with the configuration option enableOverflow.
Menu Overflow
Menus now also handle overflowing in a more gracious manner. Whenever a menu gets so long that the items won’t fit the viewable area, it provides the user with an easy UI to scroll the menu. This feature is turned on by default and can be disabled by the configuration option enableScrolling.
ToolTips
Tooltips now support an anchor configuration which will allow you to bring attention to a particular element or component with a small callout arrow.
Buffered GridView
Buffered GridView enhances performance by waiting to render rows until they are visible. As your user scrolls away from content which is no longer visible, the BufferedGridView will clean up the old DOM markup to minimize the DOM structure. As a result of the smaller markup, the performance of resizing, forceFit, autoExpandColumn and other layout and DOM manipulation features in a large grid will improve substantially. Buffer GridView is limited to working on fixed height rows.
Upgrading
Ext GWT 2.0 is a major upgrade from 1.0. There are a number of breaking changes to consider when moving from 1.X. There is a migration guide in the Ext GWT download which documents the API changes. Make sure to take a look at this before you begin upgrading to 2.0.
We are offering a pre-release sale with hefty discounts to upgrade your 1.x license. If you’ve thought about purchasing an Ext License, for a limited time, you can purchase online for less than an Ext GWT 1.x License. There’s no better time to support the Ext team.
Google IO
I will be attending the Google IO conference next week. If anyone is interested in having an informal discussion about Ext GWT, I will be available. You can private message me in the forums if you would like to meet up (darrellmeyer).

Very nice…
Keep up the good work guys!

Great!
I see the changes are in comparison with the 1.0 branch, and not with in comparison with the 2.0-m1 release…
Is there a place where the bugfixes can be found?
Posted on May 20th, 2009 at 1:32 pm
Nice release, but I found many bugs in the chrome (try type something in the forms). But once again, thanks gxt team!
Posted on May 20th, 2009 at 2:21 pm
great news!
what’s the difference between the new HBoxLayout and a HorizontalPanel (same for vertical)? Is there a complete overview of the gxt layout somewhere with hints when to use which?

Rvanlaak,
The changes are in the release notes and migration guide.
Fulvius,
What OS and version of Chrome are you using? We see no issues with Chrome.

I currently have a Silver support license. Does the 2.0 release mean that I can only ask on the premium forum for 1.x issues?
Posted on May 22nd, 2009 at 5:56 am
Fantastic work.
Keep up the good work.

Pepe,
Support subscriptions are valid for one year, independent of release. You can ask either 1.x or 2.x questions with a support subscription.

Very very nice buddy. Specially I appraise HTML editor and Chart features. All the new features are looking quite good at first look.

效果很炫，功能很强大

Great work !
But I have some problems in Chrome (1.0.154.65) – I cant’t, for example put any text in combo in Advanced ComboBox.

Great news.
A lot of very good new Stuff !!!
But a great feature is still missing : reordering grid columns

The buffered grid is great. Combine that with Live(Active) Grid and we’d be all set
The examples are down though.

On IE the HTML editor generates mark-up with upper-case tags. This will cause problems for anyone hoping to use it to generate XHTML content.
Posted on May 28th, 2009 at 10:27 am
Charts gallery is great.
Is there color control available so that I can change color.
Posted on May 29th, 2009 at 3:41 pm
GWT Team, I was looking at the chart capabilities that you had as a demo. Three questions:
1) How do you change the orientation of the barchart? From the examples they are all vertical bars.
2) Does GWT 2.0 have the capabilities as your image located here:

I know there are several Ext JS applications, I was wondering about Ext GWT, this would be a very nice application to obtain.
3) Besides the AreaChart, will the other charts have an alpha fill capability?
Thanks

Hi there,
Could someone please try the following example in Google Chrome:

It works for me in Firefox but not in Google Chrome and want to know if it is only my issue.
Thanks!

Our organization is evaluating UI frameworks for our applications.
EXT GWT 2.0 naturally came up. We have been told that GWT does not ‘fit well’ into j2ee frameworks based on an MVC model. If this is incorrect, we would appreciate objective technical documentation explaining how EXT GWT does ‘fit nicely’ into an MVC model. /thanks
