History
, Windows NT 4.0, Windows 2000 and Windows XP From Windows 1.0 to Windows XP, it was represented by an hourglass. Windows Vista introduced a new, animated wait cursor. The wait cursor in Windows 7 was almost identical. It is possible, however, to change the appearance of the cursor into the original hourglass cursor. Windows 8 introduced a new flat wait cursor, which is light blue on dark blue and removes the fade and the particles from the animated part.
Usage
There are two uses for the wait cursor: short term and long term. The wait cursor is a shared resource in the system across applications and windows. By default, when the mouse cursor is in a window, the cursor shown is controlled by the window's registered window class and handling of WM_SETCURSOR . Different scenarios can be used instead. In Microsoft Foundation Class Library (MFC) the wait cursor can be controlled by CWaitCursor . If a local instance is created, the wait cursor is reset when the instance goes out of scope. It is used primarily for short term wait cursors. In Windows Forms, each Control instance has a Cursor property, which can be controlled by the application itself. Control.Cursor is the cursor shown when the mouse is in the control's region; System.Windows.Forms.Cursor.Current is the cursor shown when the mouse enters any window of the application. For long term wait cursors, the UseWaitCursor property can be set (either Control level or application level) on one occasion and reset at another time.
