Pegboard is a window manager. It simplifies the process of creating, managing, and interacting with windows (dialogs) within your web application. It has been tested in FF 3 and Chrome. It should also work with other Webkit browsers and works with IE8. Other versions of IE were not tested.

It uses jQuery and jQuery UI to accomplish a chunk of the window functionality such as dragging and resizing. The Dialog jQuery UI widget is not used by default but can be used through the jWindow plugin, if one so desires.

Pegboard is not a web desktop like eyeOS or any other web based desktop replacement. It could be used by such an application but that is not why Pegboard has been created.

I've written a post detailing how to get started with Pegboard javascript Window Manager here.
