Use
This code is returned from Wimp_Poll and indicates that the mouse pointer is now directly over the windows visible work area.
Notes
This code is usually returned when the mouse pointer has moved over a window’s visible work area, however, it can also happen due to operations that results in the pointer finding itself directly over the windows visible work area, such as when a menu that the mouse was over, closed.
If a pointer is over a window and it is deleted just before creating a new window and displaying it, the following will happen:
- Wimp_Poll will not return a Pointer_Leaving_Window for the old window
- Wimp_Poll will not return a Pointer_Entering_Window for the new window
