EECS 1012 Lecture 33 Notes
Introduction
Desktop tasks
• The user can arrange the desktop to his or her own preferences, can easily move around
the desktop to perform different tasks, and can see the results in WYSIWYG (what-you-
see-is-what-you-get) form.
• Windowing systems from different vendors take on different appearances, but share
similar elements.
• Normally, a graphic interface consists of one or more screens or desktops, each of which
contains one or more windows.
• A window is a portion of the screen that is allocated to the use of a particular program,
document, or process.
• Windows contain gadgets or widgets for resizing the windows, for moving the windows
around the screen, for scrolling data and images within a window
• For moving windows in front of or behind other windows on the screen
• Windows usually also contain a title bar that identifies the window.
• There is also at least one menu bar on the screen.
• On some systems, a single menu bar on the screen is always associated with the active
window (discussed shortly).
• On other systems, each window has its own menu bar.
• Each item on the menu bar can be used to activate a hierarchical set of pull-down
menus, used for selecting options within the program being executed.
• Windows and Linux screens also provide a task bar for rapid program start-up, task
switching, and status information.
• On many modern systems, Windows can be configured to look and act in different ways.
• As we already noted, one important option is the Web interface, which provides the
look and feel of a Web browser for all operations within the window.
• Many systems allow windows to be iconified, tiled, overlapped, or cascaded.
