Gwt-Ext 2.0.4 is out

Tag: Ext, Gwt, Java, Programming, Web — Abhijeet Maharana @ 10:37 pm

Gwt-Ext 2.0.4 was released today. Mario announced the release at http://gwt-ext.com/forum/viewtopic.php?f=12&t=1622. I quote from the release notes.

Features

  • Support for GWT 1.5 RC1
  • FF3 Support
  • PageBus
    Messaging support which allows loosely coupled components to communicate with each other via traditional pubhish / subscribe paradigm. See demo in Showcase under ‘Miscellaneous -> Publish Subscribe’

  • Eclipse Project Files
    You can now use GWTExt directly from SVN as an Eclipse project. You just need to add the GWT_HOME variable to point to the GWT Directory in Eclipse
    Windows|Preferences|Java|Build Path|Classpath Variables

Changes

  • Various Bug Fixes
  • Fixed Memory leak when add and remove Panels (Mix of GWT and GWT-Ext)

GwtExtUx Changes

  • FileTreePanel
  • SwfUploadPanel
  • CustomReader
  • Removed individual UX from GwtExtUx.gwt.xml. This means whenever a UX is needed, They have to be added individually in the users gwt.xml file.
  • Latest patch in Multiselect.js including memory leak fixes, drag back, etc…

Download the latest version from http://gwt-ext.com/download/. Gwt-Ext-UX is being subjected to some last minute tests and a new version should be out in a couple of days.

If you have just started, the forums are always buzzing with activity and you are most welcome. These beginner screencasts may also be helpful.

    Hello Khadaa,
    You can request enhancements at the forums or better, create issues for them / add them to the UX project yourself!
    I have created the issue for HTMLEditor at http://code.google.com/p/gwt-ext-ux/issues/detail?id=26.
    I am not sure if Ill be able to make some time to take it up immediately. Hopefully someone else will.

    In the meantime, you can include the JS files in your project and use some JSNI to get it working temporarily. Forum users will definitely render any help needed.

    Abhijeet.

    Hello, Abhijeet. How are you?

    I need your help. I want to use encryption algorithm (MD5, SHA1 etc) on my web portal. But I do not know how to use these algorithms. Although I found following link:
    * http://extjs.com/forum/showthread.php?p=133516#post133516
    * http://ext.vosandhowden.com/ux/crypto/sha1.cfm
    , I cannot use them. Please help me, how to use javascript code on GWT, how to use these algorithms.

    Thank you,

    Khadaa

    Hi Khadaa, I am doing good. Thanx! And hope the same for you.
    I had a look at Jeff Howden’s sample that you linked above. To use it, you will need to include the SHA1.js file from http://ext.vosandhowden.com/ux/crypto/Ext.ux.Crypto.SHA1.js in your host HTML. Then you need to write a native method to invoke the Javascript hash function

    public native String hash(String message)/*-{
	return Ext.ux.Crypto.SHA1.hash(message);
}-*/;

    You can then invoke this method to get the SHA1 hash of a string:

    String hashValue = hash(textField.getText());
hashTextField.setValue(hashValue);

    Didn’t get a chance to test this. See if it works.

    Thank your reply. Thanks, Abhijeet

    However I tested through your reply, I got following message.

    com.google.gwt.core.client.JavaScriptException: JavaScript ReferenceError exception: Ext is not defined

    at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeString(JavaScriptHost.java:129)
    …

    I include SHA1.js file into my .gwt.xml file:

    This including is true, isn’t it? What can I do?

    Thanks,

    This exception is reported when the ExtJS files don’t get included for some reason. This is discussed frequently in the Gwt-Ext forums and Google group.

    Take a look at this thread for example: http://groups.google.com/group/gwt-ext/browse_thread/thread/21e9cd5a15b69093. A search of the forums should lead you to more such discussions.
