A status bar is a graphical control element which poses an information area typically found at the window's bottom.〔 〕 It can be divided into sections to group information. Its job is primarily to display information about the current state of its window, although some status bars have extra functionality. For example, many web browsers have clickable sections that pop up a display of security or privacy information. A status bar can also be text-based, primarily in console-based applications, in which case it is usually the last row in an 80x25 text mode configuration, leaving the top 24 rows for application data. Usually the status bar (called a ''status line'' in this context) displays the current state of the application, as well as helpful keyboard shortcuts. One example is the 'vi' text editor of UNIX (from the 1970s) or newer Linux systems.〔(【引用サイトリンク】work=University of Washington, Simon Fraser University )〕 Status lines have been used for more than 30 years〔 to display advisory messages in a predefined area, rather than as pop-up messages in center screen which can block the view of related information. Sometimes, a video game places the player's vital information or Heads-up display (such as hit points, lives, and score) on a similar strip across the top or bottom of the screen; this is also referred to as a status bar. ==Examples== * The status bar of a file manager often shows the count of items in the current directory, their total size, or the size of the currently selected item. * The status bar of a web browser will sit relatively dormant when the user is viewing a page, then light up with a flourish of activity when the user clicks a hyperlink. * The status bar of a graphics editor will show information about the current image, such as its dimensions, color space, or resolution. * In a word processor, the status bar often shows cursor position, the number of pages in the document, and the state of the caps lock, num lock, and scroll lock keys. Additionally, many word processors assign the insert key a behavior similar to that of these three, to allow toggling the insertion modethe state of that is also displayed in the status bar. * Text adventures often had a status line that displayed information such as the players location, game time, and score. Infocom's customer newsletter was named ''The Status Line'' * In a spreadsheet, the status bar shows similar information to word processors, but includes the ability to highlight cells and show the average, sum, maximum value, and so forth. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Status bar」の詳細全文を読む スポンサード リンク
