.SH "NAME"
XIDefineCursor, XIUndefineCursor \- define device cursors\&.
.SH "SYNOPSIS"
.sp
.nf
#include <X11/extensions/XInput2\&.h>
.fi
.sp
.nf
int XIDefineCursor( Display *display,
int deviceid,
Window win,
Cursor cursor);
.fi
.sp
.nf
int XIUndefineCursor( Display *display,
int deviceid,
Window win);
.fi
.sp
.nf
cursor
Specifies the cursor that is to be displayed or None\&.
.fi
.sp
.nf
deviceid
Specifies the device whose cursor is to change\&.
.fi
.sp
.nf
display
Specifies the connection to the X server\&.
.fi
.sp
.nf
win
Specifies the window\&.
.fi
.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\&.
.fi
.if n \{\
.RE
.\}
.SH "DIAGNOSTICS"
.sp
.if n \{\
.RS 4
.\}
.nf
BadCursor
A value for a cursor argument does not name a defined
cursor\&.
.fi
.if n \{\
.RE
.\}
.sp
.if n \{\
.RS 4
.\}
.nf
BadDevice
An invalid device was specified\&. The device does not
exist or is not a pointer device\&.

.nf
BadWindow
A value for a Window argument does not name a defined
window\&.
