Graphics.Blank.Cursor
Contents
Description
This module exposes an overloaded version of the cursor function that can accept
a Cursor ADT argument. This may be of interest if you desire stronger type safety
than Text-based cursors provide.
Note that this module's cursor function conflicts with cursor from
Graphics.Blank. Make sure to hide cursor from Graphics.Blank if you use
cursor from this module.
