Download Konfabulator 4.5

Konfabulator can be used to widgets to install and display. Widgets are small applications that can display all kinds of information via JavaScript, such as news headlines, weather data, system settings and appointments from calendars. The program is comparable to Dashboard from Mac OS X and is available for systems with Mac OS X and Windows as the operating system. Although the current name is also the original name of this program, Yahoo! it released under the name “Yahoo! Widget Engine” for a while. For more information, we refer you to this page and for a little history you can go on this page justly. The developers released version 4.5 a few days ago with the following changes:

HTML

Yes! We’ve added HTML support to Konfabulator! It is provided by an embedded version of WebKit, the open-source engine that is also the basis of Apple’s Safari browser.

HTML objects behave like other Konfabulator objects. The content of an HTML object can be manipulated at will, and standard Konfabulator effects, such as rotation or transparency, can be applied. It is also possible to invoke Konfabulator functionality via JavaScript from within an HTML object. This allows a developer to create the entire Widget UI using HTML and Ajax.

For security reasons, only local HTML (HTML that is included in the Widget bundle) can access Konfabulator functionality. Remote HTML (HTML fetched from the Internet) is strictly sandboxed.

Flash

As if HTML weren’t enough, we’ve also added Flash support to Konfabulator. The new Flash object allows developers to load Flash content into their Widgets. The Flash object exposes all methods that are normally available to Flash developers (Play, Stop, Back, Forward, Rewind, etc.). As with HTML objects, Flash objects can be combined with other Konfabulator objects, rotated, etc. As with ‘fetched’ HTML, the bridge between Flash and Konfabulator is strictly unidirectional – it is not possible to call Konfabulator APIs from within Flash.

Shiny New DOM

If you really want to geek out, then you’ll be pleased to know that Konfabulator version 4.5 implements a W3C-compliant Document Object Model (DOM). The elements within the DOM are bridged to their JavaScript capabilities. Want to have some real fun? Walk your Widget’s DOM tree using Konfabulator 4.5.

Security

An enhanced security block in version 4.5 allows developers to specify Widget operations, such as file system access or Internet access, in fine-grained detail. This information is displayed to the end-user in a redesigned security dialog when the Widget runs for the first time. If the Widget tries to perform a potentially malicious operation that was not declared in the security block, Konfabulator stops the widget from running. If the security block is not present, the user is notified that full rights are being granted to the Widget — this allows legacy Widgets, which were created without a security block, to run.
