| Bit | |
|---|---|
| 0 | Enable horizontal autoscrolling |
| 1 | Enable vertical autoscrolling |
| 2 | Enable scroll requests – AutoScroll will send Scroll_Requests rather than use Open_Window_Requests to scroll the window |
| 7 | Read the current state of the AutoScroll call in progress – other bits are ignored |
| All other bits are reserved | |
These bits are used in conjunction with Wimp_AutoScroll to specify how automatic scrolling is handled by an application.
