.SH DESCRIPTION
.\" $Header: XDefCursor.d,v 1.2 88/06/11 07:49:58 mento Exp $
If a cursor is set, it will be used when the pointer is in the window.
If the cursor is
.ZN None ,
it is equivalent to
.ZN XUndefineCursor .
.LP
.ZN XDefineCursor
can generate
.ZN BadCursor
and
.ZN BadWindow 
errors.
.LP
.\" $Header: XUndefCursor.d,v 1.2 88/06/11 07:54:20 mento Exp $
The
.ZN XUndefineCursor
function undoes the effect of a previous
.ZN XDefineCursor
for this window.
When the pointer is in the window,
the parent's cursor will now be used.
On the root window,
the default cursor is restored.
.LP
.ZN XUndefineCursor
can generate a
.ZN BadWindow 
error.
