Graphics.Blank.Cursor

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.

Overloaded cursor

cursor :: CanvasCursor cursor => cursor -> Canvas ()

Change the canvas cursor to the specified URL or keyword.

Examples

cursor $ url "image.png" default_
cursor crosshair
