Basically, this means that a layer (similar in some ways to layers in Adobe Photoshop) in the KDE desktop could function the same way that Dashboard does in Mac OS X. Widgets themselves are not inherently difficult to write nor properly interpret, since they are usually just HTML and Javascript (although Cocoa code can be included, the developer’s skills permitting). Furthermore, since Konqueror and Safari share very nearly the same rendering engine, KHTML and WebKit, this too will simplify the process.
This is great news, especially since some of the Apple widgets are quite useful. The latest KDE includes Super Karamba which is similar to Apple widgets, but it would be nice to be able to carry your widgets from your Mac PC to your Linux PC. Source: Slashdot.
