WindowBase class

Top-level container for a browser tab or window.

In a web browser, a WindowBase object represents any browser window. This object contains the window's state and its relation to other windows, such as which window opened this window.

Note: This class represents any window, while Window is used to access the properties and content of the current window or tab.
