set-cursor in window<%>

Sets the window's cursor. Providing #f instead of a cursor value removes the window's cursor.

If a window does not have a cursor, it uses the cursor of its parent. Frames and dialogs start with the standard arrow cursor, and text fields start with an I-beam cursor. All other windows are created without a cursor.
