Window Interface

The Window interface provides properties and methods for accessing the windows and documents in the object model. A window object is an instance that implements the Window interface and represents the area where a Document is loaded into the browser. In a tabbed browser, each tab has its own window object; one window does not have access to the window object in any other browser tab. There is also one separate window object for each browser window and some methods, such as resizeTo and resizeBy, are delegated to one of these because they apply to a whole application window rather than a single browser tab.
