Ext GWT 1.1 Released
Written by on September 18th, 2008 in Uncategorized.
Darrell Meyer has announced the release of Ext GWT 1.1 which is said to “shortens the feature set gap between Ext JS.”
New Features
The Grid component wraps the Ext JS grid, and it includes support for grid plugins which fit into component lifecycles. You can also use a subclass, EditableGrid which…. allows you to edit content on the fly.
Auto complete has been added to the combo boxes a la Google Suggest.
Portal is a custom layout container that uses a multi-column layout on contains Portlets. Each Porlet can be drag and dropped to change order or move to another column. Each Portlet can contain any content and supports icons to expand / collapse, close, etc.
The desktop mimics the behavior of the operating system look at feel. It is now possible to create multi-window applications with support for a task bar and start menu. Windows support normal, maximize, and minimize states. The start menu is a custom menu that allows new menu items. In addition, there is support for a “task” area for adding additional items.
Java Bean Support with BeanModel
The Ext GWT Store and Binder API work with ModelData instances. The primary goal of ModelData is to provide a type of “introspection” as GWT does not allow runtime inspection of Java objects. You can query ModelData for a list of properties it contains, and these properties can be retrieved and set using the parameter name with the get and set methods.
Although this approach works, it forces you to either implement the ModelData interface in your Java Beans or extend the Ext GWT base classes that implement the ModelData interface. What is missing is a way to use your Java Beans as is, without having to extend the Ext GWT base classes or implement an “invasive” interface.
There are also new examples:
- Forum search is an example of a combo box, using a custom XTemplate, and remote data. The data can be paged with built-in support for a paging toolbar.
- Image Chooser shows loading a ListView in a Window. Each item has a linked details view, and the ListView supports custom sorting and filtering.
- This example shows a Dialog using an AnchorLayout to “anchor” the form fields to the dialog dimensions. When resized, the fields will adjust their size to match the dimensions of the dialog.
