Here are some Swing links that you might have missed during this week:

• Kaushik Sathupadi writes about implementing mouse gestures in Swing. Personally, i haven’t found mouse gestures to be overly useful until now, but your users might have a different opinion.
• Danny Coward, Ken Russell and Richard Bair host the “Ask the Experts” session this week on 6u10 over at SDN. Last year Two years ago i wasn’t too lucky and my questions were screened out, but things may change this year.
• Michael Gvirtzman has a new Swing application called “Golden Rules”. It allows several planning levels, actual effort tracking, mind mapping, and contact management, providing function-rich goal system for both beginners and professionals and uses SwingX.
• JavaSwing.net has a short tutorial on InputVerifier, including background on relevant scenarios and sample code.
• Business Swing applications don’t have to be ugly (especially if you’re willing to depart from Metal / Ocean), as the new round of Palantir screenshots shows.
• Clemens Eisserer is one of the chosen finalists for the OpenJDK Innovators’ Challenge with his proposal for implementing XRender pipeline for Java2D. You can follow his blog to track the progress, and this week he announced that the project itself will be hosted at java.net.
• Greg Brown has posted the second part of a practical introduction to the new Pivot UI framework.
• Matt Fletcher writes about his experiences in rolling a JRuby desktop application.
• On a related topic, Mario Aquino has two new screencasts on desktop JRuby libraries. The first screencast is on Cheri and the second screencast is on Monkeybars.

Jeff Friesen is a prolific Java desktop author on such sites as JavaWorld.com and InformIT.com, and his article on parsing .ico files and exposing the icon planes as BufferedImages. One of the areas mentioned in our JavaOne presentation on high-resolution monitors is scaling the application icons, and the org.jvnet.flamingo.common.icon.ResizableIcon interface aims to provide this support.

It was relatively easy to adapt Jeff’s code and create an implementation of ResizableIcon interface that loads .ico files and chooses the best icon plane for the specific size. The org.jvnet.flamingo.common.icon.IcoWrapperResizableIcon is the implementation and you can see how it is used in the test.imageviewer.IcoViewer.

Here is a screenshot of this application showing file icons from the Jordan Michael‘s portfolio under 128*128 size (click for the full view):

and here is the same application with the icon size changed to 256*256 (click for the full view):

The code for parsing the .ico format has been contributed by Jeff under the BSD license. The following must be referenced if you reuse this code in your application:
