Use
The purpose of this call is to set the size of the work area dimensions of a specific window.
Notes
After setting the work area sizes, it is most likely that the Wimp will need to redraw the scroll bars to reflect the new total size of window.
The work area extent cannot be changed so that any part of the visible work are lies outside the extent. i.e. a windows current size cannot be changed, causing it to scroll.
