XIDEFINECURSOR(3)XIDEFINECURSOR(3)NAME
XIDefineCursor, XIUndefineCursor - define device cursors.
SYNOPSIS
#include <X11/extensions/XInput2.h>
int XIDefineCursor( Display *display,
int deviceid,
Window win,
Cursor cursor);
int XIUndefineCursor( Display *display,
int deviceid,
Window win);
cursor
Specifies the cursor that is to be displayed or None.
deviceid
Specifies the device whose cursor is to change.
display
Specifies the connection to the X server.
win
Specifies the window.
DESCRIPTION
If a cursor is set, it will be used when the device's pointer
is in the window. If the cursor is None, it is equivalent to
XIUndefineCursor.
The deviceid must be a master pointer device or a BadDevice error is
returned.
XIDefineCursor can generate BadDevice, BadCursor and BadWindow.
The XIUndefineCursor function undoes the effect of a previous
XIDefineCursor for this window. When the pointer is in the
window, the window's default cursor will now be used. If no
default cursor is defined, the parent's cursor for this device
will be used (if defined) or the parent's default cursor will
be used.
XIDefineCursor and XIUndefineCursor are identical to
XDefineCursor and XUndefineCursor but specify the device
explicitly.
XIUndefineCursor can generate a BadDevice and a BadWindow
error.
DIAGNOSTICS
BadCursor
A value for a cursor argument does not name a defined
cursor.
BadDevice
An invalid device was specified. The device does not
exist or is not a pointer device.
BadWindow
A value for a Window argument does not name a defined
window.
