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.
