windows manager

windows manager (window manager) A program for organizing the windows of a graphical user interface. The position, size, and contents of a window can be controlled by an application. There may be many applications active at any one time, and each application may have more than one window active at any one time. Windows are created, managed, and closed down by requests from the applications to the windows manager; the applications are clients while the windows manager is the server. All changes to all windows are controlled by the windows manager, which will check the validity of a request from an application and then update the contents of the application's window in accordance with the request, returning a message to the client on the outcome of the request. In addition, the windows manager continuously monitors the position of the mouse cursor, reporting the position of the mouse to an application at any time when the cursor is positioned within a window associated with that application, and generating an “event” when a mouse button is pressed or released. The application can use information about the state of the mouse button, and the cursor position within the window, to control the running of the application. The windows manager also offers some common functions, such as the ability to resize a window, to drag the entire window, and to iconize the window – shrinking its size to the minimum possible. When the windows manager changes the size of a window the client application is informed, and can then redraw the contents of the window appropriately.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
