    • IWorkbenchWindow:A workbench window is a top level window in a workbench. Visually, a workbench window has a menubar, a toolbar, a status bar, and a main area for displaying a single page consisting of a collection of views and editors. Each workbench window has a collection of 0 or more pages; the active page is the one that is being presented to the end user; at most one page is active in a window at a time. Same as Activity???
