The Spinning wait cursor is a variation of the mouse pointer arrow, used in Apple's OS X to indicate that an application is busy. The icon is also commonly referred to as the spinning beach ball and the spinning wheel of death. Officially, the ''OS X Human Interface Guidelines'' refers to it as the spinning wait cursor,〔(【引用サイトリンク】url=http://developer.apple.com/library/mac/#documentation/userexperience/conceptual/applehiguidelines/UEGuidelines/UEGuidelines.html )〕 but it is also known by many other names. The spinning wheel is used in many other operating systems and contexts. == History == A wristwatch was the first wait cursor in early versions of Mac OS. Apple's HyperCard first popularized animated cursors, including a black and white spinning quartered circle resembling a beach ball. The cursors could be advanced by repeated HyperTalk invocations of "set cursor to busy." The beach ball cursor was also adopted to indicate running script code in the HyperTalk-like AppleScript. These cursors are activated by applications performing lengthy operations. (Microsoft Windows would later adopt the Apple Lisa hourglass for the same concept.) Some versions of the Apple Installer used an animated "counting hand" cursor; other applications provided their own theme-appropriate custom cursors, such as a revolving Yin Yang symbol, Fetch's running dog, Retrospect's spinning tape, and Pro Tools' tapping fingers. Apple provided standard interfaces for animating cursors: originally the Cursor Utilities (SpinCursor, RotateCursor) and, in Mac OS 8 and later, the Appearance Manager (SetAnimatedThemeCursor). 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「Spinning pinwheel」の詳細全文を読む スポンサード リンク
