Zero Kelvin Desktop (ZKD) / News: Recent posts

We have upgraded the ZK Desktop to use ZK 3.0.5. There are some minor rendering changes between prior versions of ZK and 3.0.5 - check your apps when you upgrade!

Updated to support ZK 3.0.0-FL-2007-11-01.

Upgraded to ZK-3.0.0-FL-2007-10-15.

While our news feed has been idle, we sure haven't been! Today a new Zip-and-Run demo of the latest Zero Kelvin Desktop code is available on our project page. This release contains many bug fixes, API enhancements, and general updates.

In addition to the new demo, the SVN repository has been completely updated, the installation documentation updated (and verified!), and lots of other small edits here and there on the wiki and in the code.... read more

After upgrading to the latest 2.5.0 Freshly based version of ZKD, you need to add a new configuration file (zk.xml) to your installation. Please see the documentation section "Configuration" for more information.

YUIExtz 0.6.0 has been added to our ZK distribution. ZK has been upgraded to 2.5.0 Freshly 2007-08-25.

Using the new Kickstart utility during the installation now allows Mac OS X, Linux, and other UNIXish users easily install the Zero Kelvin Desktop!

The Kickstart utility also allows all users to place the installation in any location they like. You are no longer restricted to the pre-determined installation directory.

After far too long, the installation instructions have been updated with a new procedure that is *VASTLY* simplified from what was online before.

If you had problems setting up Eclipse and ZKD before, give it another try - it's a snap!

The "ZK Desktop" has been re-branded the "Zero Kelvin Desktop". Spread the word!

With the addition of the WonderGrid and the fix of the session-timeout bug (thanks, Tom for ZK 2.5.0 Freshly), we are proud to announce that we've promoted the status of the ZK Desktop project to "Production/Stable"!

We use ZKD daily to develop intranet applications for a large company and feel it's ready to move out of the beta phase.

Join us for the road to "Mature" status! We're always looking for new contributors. Stop by our chat room or forums and say "hello"!

Migrated to Tomcat 6 and ZK 2.5.0 Freshly.

Core
- Updated included Tomcat to 6.0.13.
- Updated to ZK 2.5.0 Freshly 2007-07-17.
- The IPC system no longer prevents session timeouts.

NOTES
- With the switch from Tomcat 5 to Tomcat 6, you will need to edit your
project's build settings for the new server. Be sure you delete the
"Apache Tomcat v5.5" server runtime and add the v6.0 runtime in the
"Window->Preferences" dialog under "Server->Installed Runtimes".

This release is intended for use on Eclipse 3.3.

Core
- Cleaned up project build settings.

- getGridParentVbox() API method added.

NOTES

ZK 2.4.1 support has been added. This corrects a few rendering issues with the new WonderGrid. It also adds GZIP output to improve over-the-wire performance on slow connections.

Core
- Upgraded to ZK 2.4.0.

WonderGrid
- Added WonderGridFilter class.

removeAllFilters().

when the <containchildren> setting in zkdesktop.xml was set to "false".

is no longer required.

WonderGrid
- Refactored the saving code. This slightly altered the behavior of the
editSave() method. (Since it wasn't documented anyway, nobody should be
affected by this change!)
- Added recordSave() API method for saving data into an arbitrary record,
not just the one you're currently editing.... read more

We've broken the top 500 projects on SourceForge!

Of 149,566 projects, we're currently #412!

Core
- New "addToolTips()" API method. Automatically attach tooltips to your
controls from information stored in the persistence database.
- Moved menu generation logic into it's own compiled class, "ZKDMenu".
- Moved application launching code into ZKDStatic.

or through the "Constraint" interface.
- Added "constraintClass" modifier to allow adding custom constraint code
to fields via annotations.
- New methods setShowCheckColumn() and setShowRadioColumn() to display single
and multiple selection columns along with the data in the list.
- Fixed a bug that prevented addActionButton() from working before
buildWonderGrid() was called. That's backwards!
- Many new methods added to make accessing data in the grid from action
button events and custom editing forms easier: recordGetCount(),
recordGetValue(), recordIsChecked(), recordIsLoaded(), and
recordGetSelected().... read more

We now have an EASIER-to-install demo of the ZK Desktop! Just unpack it and go! Take a look at http://zkdesktop.sourceforge.net/wiki/index.php/Demo for all the details! Wow! Exclamation points!

Core
- Window positioning code was incorrectly determining the height and width of
applications that had their height and/or width specified by the developer.
This has been fixed.

they are no longer placed directly on top of each other.

Console
- Updated layout to work properly with ZK 2.3.2.

Core
- Upgraded to ZK 2.3.2 Freshly 2007-05-30 to fix onClientInfo not firing.

"true" retains the existing behavor.
