.fi

cursor
       Specifies the cursor that is to be displayed or None\&.

deviceid
       Specifies the device whose cursor is to change\&.

.SH "DESCRIPTION"
.sp
.if n \{\
.RS 4
.\}
.nf
If a cursor is set, it will be used when the device\*(Aqs pointer
is in the window\&. If the cursor is None, it is equivalent to
XIUndefineCursor\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
The deviceid must be a master pointer device or a BadDevice error is
returned\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
XIDefineCursor can generate BadDevice, BadCursor and BadWindow\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
The XIUndefineCursor function undoes the effect of a previous
XIDefineCursor for this window\&. When the pointer is in the
window, the window\*(Aqs default cursor will now be used\&. If no
default cursor is defined, the parent\*(Aqs cursor for this device
will be used (if defined) or the parent\*(Aqs default cursor will
be used\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
XIDefineCursor and XIUndefineCursor are identical to
XDefineCursor and XUndefineCursor but specify the device
explicitly\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
XIUndefineCursor can generate a BadDevice and a BadWindow
error\&.

.SH "DIAGNOSTICS"
.sp
.if n \{\

.nf
BadCursor
       A value for a cursor argument does not name a defined
       cursor\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4

BadDevice
       An invalid device was specified\&. The device does not
       exist or is not a pointer device\&.

.if n \{\
.RE

BadWindow
       A value for a Window argument does not name a defined
