An important area where Google Desktop for Linux is different from its siblings on other operating systems is support for gadgets. Now, the Linux version of Google Gadgets will extend the gadgets platform to Linux users. By enabling cross-platform gadgets, a large library of existing gadgets are immediately available to Linux users. In addition, gadget developers will benefit from a much larger potential user base without having to learn a new API.
There's two main components to the application: one is a common gadget library responsible for running and presenting a gadget, and the other is a host program that allows the user to choose gadgets and run them on the desktop. Currently we have hosts written for GTK+ and QT, with the GTK+ host offering a sidebar similar to that of Google Desktop for Windows.
