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.
